The Apple iPad 2 is said to have a battery that lasts for 10 hours on a full charge. Unfortunately, the battery life does decrease over time, so to delay this decay, make sure that you are properly charging your iPad 2. After a full charge, use the tablet until its battery indicator shows a red status, indicating that a charge is necessary. By constantly charging the iPad before its battery is this low, you'll be speeding up the aging of its battery.

If all you want to do is read books and want a light unit with long battery life, buy an e-reader. If you want to run games, business apps, stream videos, do video conference calling and such, buy an iPad.
