Unchanged: Battery life
As with iPad 2, this is a big deal: high definition screen, CPU and GPU boosts, LTE are all potentially power hungry. Apple promises that new iPad will get the same battery life as iPad 2: 10 hours, including 9 hours of LTE (or 3G for iPad 2) connectivity. The new iPad includes a more powerful battery: 42.5-watthour, rechargeable lithium-polymer battery versus 25 watthours for iPad 2.
