The iPad will be drained 1.2 hours quickly, if the new iPad is removed from charging as soon as it shows 100% on the battery indicator.
Well the benefit-of-the-doubt here can be given to Apple. As they have clearly mentioned in the technical specs; that iPad will give 10hours of web surfing. check the new iPad's specs sheet at http://www.apple.com/ipad/specs/
The tests performed on the new iPad battery were quite closer to the previously released iPad2
The fully charged iPad ran for 11.6 hours, and the one which was removed right after it shows 100% on battery indicator runs around 10.4 hours, which is about 10% less.The new iPad has 42.5watt hour battery, which is quite bigger than the pervious iPad 2 battery which was 25-wat-hour battery.
The new battery actually still consumes around the same play time i.e. 10hours as was the previous iPad2. All of the energy of the new iPad is actually consumed in the new technology Apple has placed in the new iPad which is :-
- 5-mega pixel iSight camera
- Dual-core Apple A5X custom-designed, high-performance, low-power system-on-a-chip with quad-core graphics
- Retina display
- 9.7-inch (diagonal) LED-backlit glossy widescreen Multi-Touch display with IPS technology
- 2048-by-1536-pixel resolution at 264 pixels per inch (ppi)
- Fingerprint-resistant oleophobic coating
- Bluetooth 4.0 technology
