Apple iPad 3 packs LAPTOP battery
12,000mAh power pack, anyone?
The iPad 3 contains an 11,560mAh battery, the first take-apart of the third-generation Apple tablet has revealed.
Indeed, the new gagdet is packed with power storage behind its - Samsung-made, seemingly - 2048 x 1536 "retina display".

The autopsy, conducted by iFixit, shows a mere sliver of a motherboard up above the monster battery.
That mAh rating amounts to 43Wh - almost double the 25Wh battery capacity built into the iPad 2, and bigger than the 35Wh battery used in the latest 11in MacBook Air notebook computer.

Yet the iPad 3 runs for only as long as its predecessor, a fact that shows just how much juice the LTE 4G radio and that big screen can swallow. ®

I'd rather
have the bigger battery in the older model, I think.
Overnight charge only?
Does this mean a longer full recharge cycle time compared with the '2'?
Got that the wrong way around
We could equally well say that what is lagging behind is the power efficiency and power management technology to provide the capabilities. If you look back over the history of battery powered compute devices such as mobile phones and laptops you'll see that most of the gain has come through reduction of energy consumption rather than increase in energy storage.
4g power drain
Given that the difference in life between the 4g and wifi versions is the same as the ipad2 3G & wifi versions that actually suggests that 90% of that increases battery is going to the screen.
