Get lowdown on your laptop battery


Getlowdownonyourlaptopbattery
How long with my battery last when I’m on the move?” This is the one question that a laptop user never stops worrying about. You probably already have some sort of battery monitor installed natively on your system that tells you how much time and what percentage of battery juice remains. But this is often not enough.

BatteryBar from OsirisDevelopme­nt.com is a popular battery-monitoring tool for Windows. It installs as a ‘toolbar’ that can either remain docked next to the system tray or floating on top of all open windows. BatteryBar is basically a simple dell laptop batteries metre—at a glance. It displays either the charge percentage or the time remaining to charge or discharge. If you hover over BatteryBar, it displays further details, such as the battery’s charge capacity, charge rate, full run time, AC status and the wear status of the battery. However, its USP is that it saves battery status history and over time is able to ‘learn’ how to provide increasingly accurate estimates. BatteryBar has both free and pro versions. For $5 (approx Rs 250), the commercial edition adds battery profile graphs, low battery warnings and more.

Want something a little more detailed? Try BattStat from Users.rcn.com/tmtalpey/BattStat/. Another free Windows programme, it not the most polished of applications, but it was coded by a user who felt a sore need for a detailed battery-monitoring application and decided to write one himself. It resides in the system tray and uses Windows’ built-in battery support to display power usage, battery status and battery events; moreover, it can also display information such as CPU speed and usage, CPU and hard drive temperatures and so on. There is also a custom hotkey to turn off the screen in case you need to conserve battery.

Need a strong visual reminder when your laptop battery starts to run down? Power Meter Plus (Mattcollinge.wordpress.com/software/power-meter-plus/) is a tiny application (about 100 kb) that remains unobtrusive as long as your battery is charged. As charge levels start to fall, it appears in the form of a percentage meter, and gets progressively prominent as battery get lower. It can also usually position itself on a part of the screen that is not being used.

Mac OSX users ought to try out Coconut Battery from Coconut-flavour.com. It can be installed as a Dashboard widget, and shows detailed battery health and system information, including time remaining, charge cycles, maximum capacity, present battery capacity, CPU speed and temperature, memory usage and so on. It is also supposed to be able to warn you if you have the wrong charger connected to your MacBook. There is also an older version of the software available for users of earlier Mac OS versions and hardware.

SlimBatteryMonitor from Orange-carb.org/SBM is another nice Mac application. True to its name, its display icon on the menu bar is much slimmer than the native Mac battery metre. It works with both laptop and UPS batteries, and comes with various view options, including the ability to hide itself (for example, when fully charged). It also allows you to set customised low battery warning levels—something that is missing from the native battery preferences.

Of course, it goes without saying that this is a very superficial list. There are different types of battery metres out there—simple graphs that show how much time remains on the brand of laptop battery or powerhorses that provide an indepth profile of the system or just something that makes a very loud noise when your battery is about to run down.

Not change the battery cell phone is a popular


A time when we travel or travel should be in the bag ready to twelve spare mobile phone battery, for a rainy day in 2007, the iPhone turned out to change the mobile phone industry phenomena, such as slim body , for example, the shape of touch, as well as Today we explore the built-in battery-in-one form factor. Original rely on a few pieces of battery will be able to turnaround a few days of life, has now quietly bid farewell to us. So, this can not replace the ASUS F80 Series Battery"whether to fly, let's find out together.
Technology:
From a personality synonymous with a good way to save space
When the iPhone finally showed in the eyes of the world, it can not change the battery design to challenge the traditions and customs of all, but ultimately strong iPhone development, we have gradually begun to accept in such a way, opinion makers, the battery into the body which does have many benefits, not replace the battery program will save the body volume without rendering the battery out user-friendly plug, do not need to leave space between the battery and back cover, these spaces will be direct compression to allow users to have slimmer size mobile phone.
Process requirements, and also there are other ways to extend the life
As to prolong life, used a few pieces of batteries in the past round now, we have a new solution, mobile power supply it is worth considering. A mainstream brand of mobile power for 4000-8000 mA of power, enough to charge two to five times, this process is not shut down, is not affected, but also to facilitate than to change the battery, mobile power supply, the price is not more expensive than the original mobile phone batteries.
Products:
IPhone4S on, the battery is still the subject has a nominal 200 hours standby time, but users complain iPhone4S the battery does not "force", whether it is because of the powerful hardware configuration, or iOS system in power links the number of problem, "one charge" should become iPhone4S habits of users. various iPhone4S has been very well, 3.5-inch display has proved to be one of the most suitable for the screen size of the one-hand operation, dual-core A5 chip in the actual use of them can feel the upgrade for the iPhone 4.
Shortcomings:
Unable to extend the SD card
These built-in battery-in-one mobile phone is basically unable to support the expansion of storage, precisely because of the built-in SAMSUNG VP-D375W Charger battery unibody design and strive to simple and slim, they are generally in the built-in 16GB or 32GB native storage space, it not become a member of the SD card expansion slot. In this way you want to increase mobile phone capacity, can further replace the phone comes with a large space.
Increase in maintenance costs
United States University of South Carolina to an experimental figure shows the relationship between the cell phone battery discharge curve with the number of charge cycles. Because some of the built-in cell phone can not replace the battery, so we can frequently charge to maintain an adequate electricity, but continue to frequent recharging a battery, its energy efficiency will result in some reduction.
Built-in battery damage, the official Apple iPhone, for example to replace the repair time takes about 600 yuan or so, and you buy an original battery costs, but also two to three hundred dollars.
Micro-SIM card with more and more mobile phone, built-in storage space directly rather than design memory card slot, as much as possible to save space in the battery part, which is obviously present and even future for a long period of time which the entire industry design trends. Make the phone slimmer, allowing users to carry and easier to use, we are fully able to understand the vendor's original intention. See the quality and experience of the iPhone family of completely let us rest assured that being the case, why should they tangle on the battery can not change it?

Fire department: 2 injured in battery explosion at GM Technical Center in suburban Detroit


WARREN, Mich. — Two employees were injured Wednesday in a lithium battery explosion that forced the evacuation of about 80 others at a General Motors Co. facility north of Detroit, authorities said.
The explosion occurred during extreme testing of an experimental ibm thinkpad t40 2374-xxx battery in a test chamber at the Alternative Energy Center laboratory at the GM Tech Center in Warren, the automaker said in a statement.
It also caused a small fire that was quickly extinguished.
"Chemical gases from the battery cells were released and ignited in the enclosed chamber," GM said. "The battery itself was intact."
The Tech Center, a sprawling 1950s-era campus, is home to the hp compaq business notebook 6910p battery laboratory for the Chevrolet Volt electric car. The battery being tested had no connection with the Chevrolet Volt or any other GM production vehicle, according to the automaker.
Edmunds.com Senior Analyst Michelle Krebs said Wednesday's explosion could resurrect debate surrounding an investigation into the Chevy Volt and fires.
Sales of the electric car slowed last year after fires broke out in three of the cars' batteries several days after safety crash-testing. The National Highway Traffic Safety Administration launched an investigation, but closed it after determining that the car was no more risky than vehicles with conventional gasoline engines.
"And while this incident deserves some scrutiny — especially since workers were hurt — the fact is that this is the reason why new car technology undergoes rigorous testing, to try to ensure that episodes like this don't happen on the road," Krebs said.
On Wednesday, dispatchers received calls about the explosion at 8:46 a.m. and firefighters arrived five minutes later, Warren Fire Chief Dave Frederick said.
"They reported light smoke ... and some small amount of fire," Frederick said. "It was confined to the room of the explosion."
One worker was taken to an area hospital, while the second was treated at the scene. The extent of their injuries was not immediately known. Four other employees also were evaluated by medical personnel at the scene, GM said.
A hazardous materials team was called in to monitor the air quality at the facility, Frederick added.

How to stay positive in battery recycling


Have you ever wondered how you should dispose of used camera batteries when there are no recycling bins nearby?
Howtostaypositive inbatteryrecyclingSome keep them in a box at home for years, some send them to environmental protection organizations and some simply dispose of them with other household waste.
Trying to offer a further alternative, Beijing doctor Wang Zixin decided to build a battery-recycling plant - the first in China.
That was back in the 1980s, when he was at Nanyuan Hospital, in the capital's Fengtai district.
Wang had read that a small Canon LP-E6 battery could contaminate 60 liters of water. Appalled, he decided he could better use his time trying to prevent heavy metals from contaminating the earth than treating patients with respiratory and digestive troubles.
"If we had a plant in the city recycling batteries, it could make a great difference," said Wang.
As a doctor who knew little about recycling Canon EOS-300D batteries, Wang could offer little more to his new cause than passion and resolve. But in 1991, he quit his job and began conducting research into how batteries are treated in China and abroad.
He borrowed piles of books and documents, and consulted experts about the possibility of building a recycling plant and preventing leakage of poisonous gases and wastewater.
The intensive research and Wang's frequent visits abroad made him even more concerned about what happened to used batteries in China.
Wang said China uses about 8 billion batteries a year, or about 200,000 tons of them. But only 2,000 tons of zinc-manganese batteries are recycled each year.
"More than 4 tons of zinc are wasted every year because used Canon NB-4L batteries are not properly dealt with," said Wang. "That's simply a waste of resources."
As an example of what a country can do, Wang cited Switzerland. He said the Swiss use two battery-recycling plants to extract 780 tons of manganese and iron, 400 tons of the aluminum-zinc alloy, kirsite, and 3 tons of mercury every year from 2,000 tons of batteries.
In Europe, several countries can share one battery-recycling plant to reduce costs.
In 2000, inspired by seeing successful examples abroad, and in cooperation with the University of Science and Technology Beijing, Wang invested in the first plant in China to extract heavy metals from used batteries at Baoding city, Hebei province.
"If used Canon EOS 5D battery are collected and recycled, we can not only save a tremendous amount of resources but also avoid environmental pollution," Wang said.
But Wang's first attempt at turning waste into wealth failed, partly because the leakage of wastewater and poisonous gases at the plant did not meet the national standard in 2003.
Wang lost 80 percent of his savings - about 1 million yuan ($158,600) - with the closure of the plant, but his compassion and determination remained strong.
His wife, however, did not feel the same way.
"I know it was hard for her at the beginning. All the savings were gone and the whole family had to live on her income, together with my parents' small retirement pension," said Wang. "Life turned out to be so tough because I took a path that has been little traveled."
Wang said his wife has gradually come to accept the situation, but she still complains from time to time.
"The failure of the first plant was quite a blow, with little support," said Wang. "But it was also a precious lesson for me, as a novice in the field of environmental protection."
With little money left to re- invest in used-battery treatment, Wang started raising funds from friends. And one thing has made him stick even more firmly to his aims.
A friend asked him during a fundraising event: "What if you abandon the idea years later, with nothing left to pay us back?"
"The lack of trust was such an affront to my character," said Wang. "I shook hands with him and gave an oath. I said I'll make it happen, I will make it happen."
Ten years later, Wang is still pursuing his dream, "in a stubborn way", says his wife, but his second Sony NP-FC11 battery-recycling plant is due to start operating in July, in the Daxing district of south Beijing.
"With the vacuum heat treatment we have been working on in the past few years, no poisonous gas would escape, and the heavy metal, like mercury, would be extracted when the temperature reaches 357 C," Wang said.
"This will certainly meet the national standard."
But even if all goes well, the new plant will do little for Wang's finances, beyond accumulating more debt.
"Even if we get the used batteries for free, we can only make a profit of 1 yuan (16 cents) from 200 batteries, barely enough to cover workers' salaries and warehouse charges," said Wang.
That's why there are no battery-recycling plants in China, he said. No profit can be made.
"You are bound to burn your bucks if you run a Sony NP-F970 Battery -recycling plant without any funding or government support," said Wang. "I just hope my pioneering venture will at least open the way for the world's biggest battery consumer to follow."
Totally occupied in his campaign to recycle used batteries, Wang has barely had time to communicate with his 19-year-old son, who is due to take a college entrance examination around the same time that the new plant opens.
"I don't expect him to understand me, far less share my devotion, since it's been such a rough time for him going through all the hardship," said Wang. "He's got his own life."
"However, he will understand and be proud of me one day."

New iPad Owners Love Tablet's Retina Display, Battery Life



AppleStoreiPadLaunchDespite reports about Wi-Fi connectivity issues and overheating, new iPad owners appear to be more satisfied with the updated Apple tablet than ever, thanks in large part to the new Retina display.
According to a new report from ChangeWave Research, 82 percent of new iPad buyers are "very satisfied" with the updated tablet, while 16 percent are "somewhat satisfied." Only 2 percent were "somewhat unsatisfied," while no one was "very unsatisfied."
That's a jump from last month, when ChangeWave asked first- and second-generation iPad owners about their satisfaction levels. About 74 percent were "very" satisfied, while 23 percent were "somewhat" satisfied.
What features are new iPad owners most enjoying? An overwhelming 75 percent like the Retina display, followed by 22 percent who enjoy the long battery (Sony VAIO VGN-NW240F battery)life, and 21 percent who are pleased by the 4G LTE capability. Rounding out the top five most-liked features were the processor speed (20 percent) and updated iSight camera (18 percent).

There were a few gripes, however, and most had to do with money. About 26 percent were not excited by the price of the new iPad, while 23 percent did not like the cost of the wireless/data plan. About 6 to 8 percent of respondents, meanwhile, took issue with the new iPad's size/weight, amount of storage, integration with other devices, overheating issues, and battery (Dell inspiron 13r battery)life.
ChangeWave singled out the overheating issue, but 89 percent of those surveyed said they hadn't experienced an issue. Earlier this month, thermal images from Dutch site Tweakers.net showed that Apple's third-gen iPad was 10 degrees hotter than the iPad 2. Apple, however, said the updated device operates "well within our thermal specifications."
ChangeWave compared that to the 2010 "antennagate" issue with the iPhone 4. In talking to users in July 2010, 21 percent reported that it was a "very big" or "somewhat" of a problem, while 64 percent said it was not an issue. The problem eventually forced Apple to offer users a free bumper; a lawsuit over the issue was settled recently, but users will only walk away with $15 each.

A123 stocks plummet 29% after announcing faulty battery replacement plan


Shares of electric vehicle Acer Aspire 4745g Battery supplier A123 Systems continued falling to new lows this morning as one New York law firm began seeking investors who might want to sue management and the board over alleged violations of securities law.
Monday the Waltham, Mass.-based firm with plants in Livonia and Romulus, announced it would replace faulty batteries shipped to five customers, including Fisker Automotive.
CEO David Vieau said company officials discovered the problem in certain prismatic cells late last week at its Livonia facility. The defect appeared to be caused by one of four automated welding machines, he said. The company will start shipping replacement battery packs to five customers later this week, he said. It estimated the replacement effort will cost about $55 million that it will take as a charge to its earnings over the next several quarters.
By 11:40 a.m. A123 shares had fallen 14% to $1.21, up slightly from a morning low of $1.17. Since Friday, the stock has lost 29% of its value.
Earlier this morning the New York law firm of Bronstein, Gewirtz & Grossman, which bills itself as a “corporate litigation boutique,” issued a press release saying it was “investigating potential claims” of shareholders concerning whether the company and certain of its officers and directors have violated federal securities laws.
A123 spokesman Dan Borgasano declined to comment on the law firm’s statement.
Earlier this month, Consumer Reports disclosed that a $108,000 Fisker Karma flashed an error message and locked in gear with just 180 miles on the odometer, while being driven at the magazine's Connecticut testing center. The cause of that shutdown was associated with A123’s defective batteries, said Vieau, who declined to identify other customers who received defective MOTOROLA Cell Phone battery packs.

PREP SOFTBALL: Lakeside's battery-powered program looks for knockout punch in 2012


LAKE ELSINORE — A pitcher and catcher working on the same page is mandatory in high school softball. Standouts at the two positions are a plus.
Having senior pitcher Jasmine Smithson-Willett and junior catcher Austen Urness as your laptop battery? No, not "priceless." But definitely a game-changer, and in Lakeside High's case, a program-changer.
The two cornerstones of the Lancers softball team are entering their final year together, and that means a final chance at high school success — perhaps the last benchmark to elude them in their years on the northwest side of the lake.
Both are accomplished travel-ball players. Both have Division I scholarships in hand. And both are among the best in the Valley at their respective positions.
"I think they challenge each other," Lakeside coach Todd Naylor said. "They challenge each other at practice. When we pitch live, the teams get real quiet and it becomes a battle."
Now, they want respect for their team.
Despite the program's success and talent on the roster, the Lancers have yet to get past the second round of the CIF Southern Section postseason, having lost in that round each of the last three years. That stretch included a heartbreaking 6-4 loss to Hesperia two years ago that abruptly ended an undefeated league season and 23-3 campaign. Last year, the Lancers were bumped out of the second round by West Covina South Hills.
"I kind of like losing last year, because it gave everybody almost a slap in the face," Smithson-Willett said after Monday's practice. "It was like, 'If we don't play like we know we can, we're going to get beat.'"
So here's their chance in 2012. For the Lancers and their dynamic duo, it's been quite a ride to this point.
Smithson-Willett established herself as an ace as soon as she stepped into the Lakeside circle as a freshman, and the program transformed from second-division status to Sunbelt League frontrunner. In travel ball, she helped the Upland-based SoCal Athletics 18-and-under Gold team — a club that also includes Great Oak standouts Danica and Mo Mercado — win back-to-back national championships.
In three seasons of high school softball, she's won 53 games, allowed just 89 earned runs in 443 innings and has struck out a whopping 567 batters.
Willett can attribute much of her progress to her catcher. Naylor has allowed Urness to call Willett's pitches since almost the beginning — "I called the first game, gave her the second and the rest is history," he said — and the development of her change-up to a plus-screwball and strong fastball has made her a force.
"It makes things 10 times easier. It makes pitching easier," Willett said of working with Urness. "(With) her calling the game, it makes me more confident because I know that if she calls a change-up, I know that it's going to be the right pitch because that's how she feels.
"It's kind of like that telepathic feeling."
Telepathy didn't lead Urness to Lakeside, but some could have thought so. She showed up in Naylor's program as a freshman already with a verbal commitment to Nebraska in her back pocket. That raised some eyebrows, especially with former Vista Murrieta star Taylor Edwards in Lincoln, Neb., just two years ahead of her.
But Urness has more than proved her worth, and last year, she began exhibiting Edwards-like numbers, hitting .443 with nine home runs and 32 RBIs.
Behind the plate, there has been a learning curve, too. Urness said she's worked hard this season on throw-downs to second base, as well as manipulating her calls for Smithson-Willett.
"Definitely from my side, it's (about) calling a smarter game," she said. "Last year, we kind of just threw to (Smithson-Willett's) strength, and now we need to start throwing to hitters' weaknesses."
That means knowing the hitters, finding the soft spot in their zone and using her pitcher's four-pitch arsenal to her advantage.
"They're really fun to watch," Naylor said.
The two share a bond, and it's one developed through the high school game. Though they attended middle school together, they barely knew one another prior to Lakeside.
"Out on the field, we have handshakes and we definitely have the same lifestyle," Urness said. "We're both committed, we're both going to college, and we're on a track, basically, so we definitely share knowledge with each other."
They compete, too, in practices in live pitching, and as quality hitters manning the Nos. 3 and 4 spots in the Lakeside lineups. Together, with senior Megan Bartee (.455, 16 RBIs last year), they form the heart of a formidable batting order.
That production will be needed as they enter an improved Sunbelt League. Lakeside shared the league crown with Heritage last year, and the Lancers suffered league losses to both the Patriots and Paloma Valley. All three expect to challenge for the league crown.
And then, when those darned playoffs come around, the Lancers expect to be ready.
"We as a team have worked so much harder this year and so much longer," Urness said. "We started in August, and we have been working since August and have been working hard on the field. We've been working hard on the little things that we need to do to improve and get past the second round of CIF."

New iPad 3 battery life problems uncovered, retina display to blame?


Major battery-life problems are affecting the new iPad, user testimonies suggest, as Apple’s latest tablet becomes embroiled in a perfect storm of teething problems.
Earlier this week, it emerged that some new iPad owners are experiencing overheating problems. Things took a turn for the worse for Apple days later when hundreds of users expressed concern that their new wonder device struggles to connect to wireless networks.
TheNewiPad-white
Today, what appears to be another glitch with the device still being informally dubbed the iPad 3 has surfaced. This time, users have taken to Apple forums en masse to complain that their tablet suffers from cripplingly short Canon Nb-8l Battery life and takes aeons to charge.
According to device diagnostic doyennes DisplayMate, the blame rests squarely on the HD display and the battery-hungry LED backlight it uses. The company claims that this tears through power at three times the rate of the iPad 2.
Raymond Soneira of DisplayMate told CNET: “The power consumption of the LEDs is 2.5 times that of iPad 2, and the battery is 1.7 times larger - if you run your new iPad at full brightness, the Studio 1537 Battery run time is less because you only put in 70 per cent more battery but you're using 150 per cent more power.”
Apple has yet to acknowledge reports of battery longevity problems. But as soon as it does, we’ll let you know.
In the meantime if you’re one of those affected by sub-par Fujifilm Np-40 Battery life, tell us about it in the comments section below.

Researchers finally discover a use for LightScribe


Supercapacitors formed by the mighty power of DVD-RW drives - and a bit of graphite oxide and hard work...

What does graphite oxide, a DVD, and a burner with LightScribe functionality have in common? They're all part of a research project which resulted in the production of reliable ultrahigh energy density supercapactiors, a technology that's been touted as a possible solution to lacklustre energy storage in modern machines.
Producing these capacitors involves spreading a layer of graphite oxide onto an ordinary DVD, then inserting it into a LightScribe capable burner. The graphite is then reduced to a mechanically robust graphene lattice with high conductivity and surface area (an important factor for capacitance). Two of these sheets sandwiched together with a dielectric separating them act as a complete flexible capacitor, measuring less than 100 microns thick. The Science paper by Maher F. El-Kady, Veronica Strong, Sergey Dubin, and Richard B. Kaner describes the process in detail.
If there's one thing that's bottlenecking the rate of which performance increases on portable devices, it's the Canon fv40 Battery technology struggling to keep up. Power efficient System on Chip (SoC) designs, larger batteries, improved display technologies such as OLED, and tight coupling of circuitry such as 4G radios all help to curb the effects of Canon Eos 1100d Battery use. Even with all these efforts, the 'battery anxiety' issues of the current generation make it difficult to become truly portable. At some stage of the day you're going to find yourself tethered to a USB or wall outlet.
It's not just gadgets either, cars and even houses lack cheap reliable and high capacity battery solutions. The future of auto is electric, but we simply cannot afford to transfer Panasonic Lumix Dmc-fz3 Battery anxiety concerns to cars - that's just insanity, which is why most electric vehicles are hybrids, or just outright expensive to cater for larger energy capacity. If solar manages to become affordable enough for the average home owner, where will we store excess power?
Research into the area of Canon Eos-20d Battery tech is vital for current tech to improve into the future. Eventually stories of battery breakthroughs will come through with a solid marketable product, but until then, we can dream of a time where we can disappear for a week and still have a functional phone and laptop.

Barnes & Noble Nook Tablet (8GB) Review


When it first debuted, Barnes & Noble's Nook Tablet went head-to-head with Amazon's Kindle Fire with a great screen, microSD card slot and a stylish design, but the company may have done itself a disservice by pricing its 7-inch color eReader $50 higher. The second iteration of the Nook Tablet keeps the same design, but halves the RAM and storage space, and, more importantly, matches the Fire's $199 price tag. However, is the Nook Tablet's performance still up to snuff?
Barnes&NobleNookTablet(8GB)Click to EnlargeStill one of the more attractive 7-inch tablets, the Nook Tablet's pewter-colored matte plastic chassis has a pleasingly rounded shape that looks and feels much more like a fancy tome than the sharp-angled Fire. At 8.1 x 5 x 0.5 inches, the Nook Tablet is slightly bigger than the 7.5 x 4.7 x 0.5-inch Amazon tablet, but at 14.1 ounces, it's 0.3 ounces lighter. It's also significantly lighter than the 15.5-ounce Nook Color, which is now $169.
The Nook Tablet sports an attractive N button below the screen, which launches the menu with one press or returns you to home with two clicks. We appreciate the dedicated volume up and down buttons on the right side. The luxuriously soft, rubberized back made it easy to grip the Nook Tablet with one hand.

Display and Audio

Like the Kindle Fire, the Nook Tablet has a 7-inch, 1024 x 600-pixel screen. According to Barnes & Noble, the 16-million-color VividView display offers better picture quality and less glare than the competition because there's no air gap beneath the fully laminated surface. Sure enough, action scenes from "The Expendables" looked better on the Nook Tablet than the Fire. Viewing angles were wider, colors were much richer and we saw less pixelation.
Though the Nook Tablet's display was sharper and more vibrant, the Kindle Fire's was a bit brighter, measuring at 460 lux on our light meter, compared with 392 lux for the Nook.
The Nook Tablet's underpowered speaker is one of its biggest weaknesses. When we tried streaming tunes from the Napster app, the drums were tinny and audio was noticeably distorted. Worse, the back-mounted speaker on the Nook Tablet becomes muffled when the tablet is placed flat on a surface or mounted in a portfolio.

Software and User Interface

Barnes&NobleNookTablet(8GB)Click to EnlargeThe Nook's completely unique user interface--now at version 1.4.2--is built on top of Google's Android operating system. Unlike the Kindle Fire's bookshelflike home screen, the Nook has a more traditional-looking desktop on its three home screens.
Overall, we prefer the Nook Tablet's UI to the Kindle Fire's, because it allows easier access to recently used apps and media, gives users the freedom to personalize the home screens with wallpaper and shortcuts, and provides a physical button for returning to the main menu or home more quickly.

Nook Tablet Virtual Keyboard

The Nook Tablet's virtual keyboard is reasonably accurate and attractive, but offers no haptic feedback and no alternate input methods such as Swype. Still, we preferred the Nook Tablet keyboard's widely spaced keys to the tightly packed buttons on the Kindle Fire.

Barnes & Noble Book Store

Barnes&NobleNookTablet(8GB)Click to EnlargeThe Nook Book Store has more than 2.5 million titles available for purchase and hundreds of popular magazines. In a quick survey of the top 10 New York Times best-sellers, all 10 were available for the same price on both the Kindle and the Nook.
Unlike the Kindle Fire, the Nook Tablet supports the popular ePub book format, so if you want to side-load some books from other sources, you won't have a problem. Like the Kindle Fire, the Nook Tablet supports library lending so you can borrow eBooks from your local public library for free. However, only the Amazon tablet gives you a free book per month from its Lending Library (provided you're an Amazon Prime member).

Barnes & Noble Comics Selection

Barnes&NobleNookTablet(8GB)Click to EnlargeThe Nook Tablet has a number of graphic novels and even a few single-issue copies of comics, including 109 graphic novels from Dark Horse Graphic Novels. Through a relationship with Marvel, the Nook has a handful of superhero titles you won't find on Amazon, including two Spiderman collections, four X-Men collections, two Iron Man collections, two Hulks, two Thors and one "Captain America."

Barnes & Noble Periodicals

The Nook Newsstand has hundreds of popular digital magazines and newspapers to which you can subscribe or purchase as single copies. You can even try any magazine for free for 14 days. All of the magazines feature a digital table of contents menu that lets you jump to different stories. Amazon's newsstand offers similar features for its magazines, and pages turned more quickly and easily.
A number of magazine titles also have interactive and multimedia features embedded in the content. The most recent issue of Parents magazine has a video cover with a barking dog and a number of hyperlinks within the pages that take you to other parts of the magazine. But there is no easy way to search for titles that offer that "something special."

Enhanced eBooks

Barnes&NobleNookTablet(8GB)Click to EnlargeBarnes & Noble offers 700 interactive children's books, and a spokesperson told us that number should rise to more than 1,000 by the end of the year. Some of the books offer page-specific interactive features, such as the ability to change the color of the main character's costume on page two of "Awesome Man." A number of the books are labeled Read and Play, which means they have professional audio recordings that pronounce the text.
Enhanced Nook Books include audio and video embedded within the story, or as additional sections, like DVD extras on a movie. For $2 more than the normal eBook price, we downloaded the enhanced version of J.R.R. Tolkein's "The Hobbit." The 146MB file took 4 minutes longer than a normal eBook to download over Wi-Fi. Also, the extra content must be downloaded separately, taking up a possible 1.51GB of storage space on your Nook Tablet. The sheer file size of books like this gives us pause when considering this version of the Nook Tablet.
That said, the extras are pretty cool. For instance, in a matter of a second or two, we were able to click a Play button in the middle of the text and hear J.R.R. Tolkien read a passage from the Riddles in the Dark section for 30 minutes. Other enhanced books include video interviews with authors as well as animations on images. Enhanced books like this aren't available on the iOS version of the Nook app.

Read & Record Feature

All of the children's books support Barnes & Noble's new Read & Record feature, which allows adults to record themselves reading each page of a storybook so their children can have story time with mom or dad's voice when they can't be there.

Social Features/Lending

The Nook Tablet's eReader has a built-in share button that lets you recommend the book to your contacts, post your reading status to social networks, rate the book, or like the book on Facebook without leaving the reader app. The reader also has a fantastic Recommend button that pops up a list of similar titles.
The Nook Friends app allows you to connect with other Nook users, see their recommendations and even loan them books. During testing, we added a friend and were able to easily send her a recommended book and see a history of every title she had commented on publicly.
Barnes & Noble makes some of its titles available as LendMe books, which means you can loan them to one of your Nook friends one time for up to eight days.

Parental Controls

In the settings menu, you can set a four-digit PIN and then block access to the Web browser and all the social features. In a completely different settings menu, you can also set a separate password for buying items from the store. However, there's no way to restrict library content by user or to disable email access.

Apps

The Nook's app store won't put Google Play or Amazon's App store out of business anytime soon. A Barnes & Noble spokesperson told us that the device currently has thousands of apps.
While there is a Twitter app, there's no official Facebook app. The only graphically demanding game we could find on the device was the racing game "Raging Thunder." Most of the other games were very casual fare, including the $0.99 Combat Helicopter from Karmic Apps, which reminded us of the original Mario Bros with a helicopter. After about a minute of monotonous play the basic flying app crashed.
Discovering apps is no picnic, either. You can browse through categories, but there's no way to search just the apps inventory. When we tried to find the game Fruit Ninja, we got a guide book to the game, but no app.

Performance

With its 1-GHz TI OMAP4 dual-core processor with 512MB RAM, the Nook Tablet offers half as much RAM as the $199 version. Still, in everyday use, apps loaded fairly quickly, videos streamed smoothly and pages flipped fast. In comparison to the Nook Color, which includes a 800-MHz TI processor and 512MB of RAM, the 8GB Nook Tablet consistently opened apps a second faster, including Netflix, Twitter and the Web browser. When compared with the Kindle Fire, the Nook opened Pulse slower by a fraction of a second, but was faster opening Netflix and Twitter. The browsers for the two tablets seemed to open simultaneously.

Storage and Expansion

The Nook Tablet comes with 8GB of internal storage, as does the Amazon Kindle Fire. However, 3GB is taken up by the operating system and then 1GB of the remaining 4GB is reserved for Barnes & Noble content you purchase, including books, apps, magazines and any future downloadable content the company may offer. That leaves 4GB of internal memory for you to fill with personal photos, music or video files, which oddly is more space than is allotted for personal content on the 16GB version.
Unlike the Kindle Fire, the Nook Tablet has a microSD expansion slot that supports memory cards as large as 32GB.

Video

At present, the two main ways to play video on the Nook Tablet are through Netflix and Hulu Plus, both of which require membership and neither of which allows you to download files for offline viewing. Though each has its strengths, neither has the kind of comprehensive selection of new releases you'd find with a pay-as-you-go service such as Amazon Video On-Demand or iTunes.

Music Playback and Options

Barnes & Noble offers a number of streaming music options, including Grooveshark, Pandora and Rhapsody. However, if you want offline music, you will need to bring your own MP3 files to the device.

Web Browsing

Web pages rendered very quickly over our Wi-Fi connection. With Flash disabled and the browser in desktop mode, we downloaded desktop versions of the NYTimes.com, Laptopmag.com and Espn.com in an average of 7.6 seconds, which is exactly the same as what we got on the Kindle Fire with the page loading accelerated. And it's only 0.2 seconds slower than the 16GB version of the Nook Tablet.

Email

Setting up the client to check our Gmail account was a breeze. However, we were unable to configure our office Exchange account, because the client only offers IMAP and POP mail support. The simple UI is attractive enough and places alerts in the status bar when you receive new messages.

Battery Life

Barnes&NobleNookTablet(8GB)Barnes & Noble claims that the Nook Tablet will last for 11.5 hours or reading or 9 hours of video playback. With Wi-Fi on and the battery pumped up to 100 percent, we used the device on and off from the morning until after midnight, so we believe Barnes & Noble's claim. We were unable to run our standard LAPTOP Battery Test.

Verdict

With a fantastic eReading experience, the best selection of interactive children's books, and a newsstand loaded with magazines, the $199 Nook Tablet is a great color eReader. We prefer the display on this device to the Kindle Fire, but Amazon's device has a superior app selection and better offline media options. Those who aren't planning to play videos or use the Read and Record feature should consider the cheaper $169 Nook Color, because it runs the same software and has the same great display. The 8GB Nook Tablet is a very good option, but it's not the best choice in this price range.

iPhone 4S battery life, charging issue finally fixed


iPhone4Sbatterylife,chargingissuefinallyfixedEver since Apple introduced the iPhone 4S last October alongside iOS 5, the iPhone and iOS 5 have been met with large groans of disappointment regarding the battery and/or charging of the Dell latitude pp01l battery. The latest version of iOS, however ( iOS 5.1), has appeared to have resolved the problem for many users.
Shortly after iOS 5 and iPhone 4S was made available October of last year, Apple released iOS 5.0.1 which was presumed to solve many bugs users were experiencing which were causing unacceptably short battery life on devices using iOS 5. The update, however, was largely deemed a complete failure and seemed to solve none of the problems and users continued to see Acer Aspire 1410 battery life of roughly 4 to 5 hours regardless of actual usage. Apple claims that the iPhone 4S is capable of 200 hours on standby, and roughly 9 hours of talk time. Actual usage had been far less.
Additionally, many users complained of improper charging on their iPhone 4S. Complaints that the Universal External Battery would charge to 100% and then drop in large steps thereafter flooded Apple’s support forums for months after the launch.
