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.
