The latest iteration of Apple's tablet, the New iPad, is just as good at staying alive as its predecessors. Ever wonder how it manages to stay on for so long though? Especially in today's age, when battery-life is definitely a major factor in people's choices for laptops, smartphones, and other accessories.
Turns out, the New iPad has a whopping 42.5Whr battery. Quick flashback: the original 1st-generation iPad had a 24.8Whr battery, while the iPad 2 had a 25Whr battery. And while the New iPad is only 0.6mm thicker than the iPad 2, one just has to wonder: how in the world did Apple do that? According to arstechnica's teardown (note: Consumers should not try this at home), Apple simply managed to "more efficiently pack in the components - and increase the overall device thickness ever so slightly". No magic here, folks.
No matter how much you want to stare at the battery out of curiosity, tearing the device apart is always dangerous and likely shouldn't be done. And as fun as it is, professionally taking it apart is definitely still a better option than dropping it - which is proven to be fatalfor the iPad, if squaretrade's blog and video is any indication.

NEC's unveiled their newest prototype of their Ultra-thin organic radical battery (ORB) today, measuring in at 0.3 mm. These batteries are not only small, but also flexible, and can be attached to integrated circuit (IC) cards. The IC cards themselves aren't too think either (measuring around 0.73 to 0.76mm thickness on average).
The power behind NEC's latest ORB is enough to match a Li-Ion battery. That's not to say that it'll run your laptop, but ratio-wise, it delivers a higher power output and faster recharging speeds. Currently, these new batteries have a capacity of 3mAh, which should be enough to perform 2,000 display screen updates, 360 consecutive flash firings and 35 location transmissions on just one charge. As far as longevity, these ORB's retain 75% of their charge/discharge capacity even after 500 cycles, similar to the performance of Li-Ion smartphone batteries.

The new Duracell Powermat will be on display at CES in Las Vegas to demonstrate wireless charging capabilities. Duracell and Powermat have struck a joint venture together to "advance and globalize wireless charging." Powermat has been looking to place their inductive charging systems in the airport, car, kitchen atmospheres and other common areas of daily use. One example is the new General Motors Chevy Volt, which will support the Powermat inductive charging system in the center console.
Check out some of the new sneak preview videos for CES 2012 in Las Vegas.

A recent groundbreaking study has led to success in increasing charging capacity and speed of lithium ion batteries. Professor Harold Kung and his group of engineers at Northwestern University have accomplished this feat by adjusting graphene layers, which are directly related to how fast charging can occur. Now, charging capcity and speed increase by a factor of ten, just by poking small holes in the battery's graphene layers.
Additionally, Kung's team also increased the density of lithium ions, which allowed for their test-batteries to last for over a week on a single charge. (The science behind it isn't so simple, of course.) The downside is that these lithium-ion batteries lost their fast-charging long-lasting abilities after roughly 150 charges, which is a drastic difference in how long lithium-ion batteries normally last.
If perfected, this science could help create the next generation lithium-ion battery. Check out the source link below for more info.

The iPhone 4S may have been praised for its addition of Siri, but this esteemed phone hasn't been without its troubles either. Since its release, the latest iPhone has had a slew of customers complaining about an extremely short battery life.
The Apple forums have been a great source of information and meetings for those with battery performance woes. Many discovered that bugs in iOS 5 were partly to blame for the sudden drops in battery life, with the bugs coming from the Calendar and Time Zone Settings. However, this doesn't limit the performance issues strictly to iOS 5.
Apple has released a statement saying an official update will be coming in the next few weeks to help alleviate these issues. In the mean-time, check out the links below from techcrunch and cnet for tips on how to get your battery to survive until the official software patch is released.
