Having a razor-sharp display, quad-core processor and huge selection of apps won’t matter much if your tablet dies while you’re trying to post a Facebook update, send a critical email or are halfway through “The Avengers.” Fortunately, we found 10 tablets with enough juice to last a cross-country flight, an epic road trip or a regular work day. Each of these slates lasted more than 8 hours on our LAPTOP Battery Test, which involves continuous Web surfing over Wi-Fi on 40 percent brightness.

The Galaxy Tab 7.7 is a glaring omission…I believe either the international or Verizon version was averaging 10-11 hours of battery life.

That any of these do not have 20 hour battery life for 5 dollars extra extra built in is ridiculous you can put in 3 batteries like high capacity camera batteries each lasting 8 hours cost was 2.00 a battery triple or quade system should be standard 14 to 20 hour system I worked in electronics over 20 years

Notice how ASUS was completely left out of this. Some of their tablets go for even longer than the iPad.

Why didn’t they include the Asus Padfone?
Afterall, it CAN be a tablet and has up to 63 hours of battery life.
