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.
Apple iPad (4th Generation)
The 4th-generation iPad leads the pack in almost every respect. It boasts one of the best displays on the market, a robust tablet app ecosystem, powerful graphics and processing performance and -- perhaps most important for all-day users -- phenomenal battery life.
Packing a 42.5-watt-hour lithium-polymer battery, Apple's latest iPad lasted an unbelievable 12 hours and 22 minutes on the LAPTOP Battery Test, well over the 7 hour and 7 minute average. If you want a tablet that will last you an entire workday on a charge (and then some), the 4th-generation iPad can't be beat.

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.
