I already told you that the new iPad tablet has a capacity battery higher than the one included in the iPad 2 and that we are talking about 11.666 mAh available for us. The tablet has a better battery because it needs more energy to work on 4G LTE networks and probably for the new screen, but the autonomy has remained unchanged according to Apple. Although in essence things seem good, in reality the problem is that the new tablet charges much harder than before and heats up a bit more than the old model.
So how was Apple able to keep the battery life the same while adding LTE and without drastically changing the design? It appears that they've had a fairly major breakthrough in their battery technology. While the new battery clearly isn't much bigger than the old one, it can hold much more juice (42 watt-hours versus 25-watt-hours). The downside of this is that I've found it takes quite a bit longer to charge the new iPad. As in several hours — you'll probably want to do it overnight.
Practically, the new tablet has 70% more energy stored in it and theoretically it should be 70% harder to charge, so we are talking about 5 hours of charging to have a battery that offers 10 hours of autonomy no matter how we use it . I assume that many of you were expecting something like this and the news is not good, but maybe Apple will find a fast charging method that will save us a few hours of charging.
