Your tablet might pack a fancy stylus or super-sharp resolution, but can
it go a day without a charger? CNET Labs takes up the challenge to find
out.
Battery life is an important, yet often overlooked feature.

Editor's note: This list is updated regularly.
Battery life testing is one of the last evaluations we subject tablets to at CNET Labs, but by no means is it the least valued. How long you can use your tablet is nearly as important as what it is you do while using it.
Our CNET labs testing standards ensure that all tablets, regardless of size, color, or operating system, are tested as close to equally as possible. Details on how we test tablets are included below the testing results chart. We've also thrown in each tablet's maximum luminosity, resolution, and pixel density for good measure.
Expect this list to be updated frequently as new tablets are tested.
