Part of the iPad's appeal is its long battery life -- Apple claims the wi-fi-only version will last ten hours, and the 3G iPad will last nine hours before needing a charge. Both of those stats are pretty impressive.Of course, what happens in the real world is considerably different than what happens in Apple's laboratory stress tests. Watch movies continuously at full brightness with push e- mail notifications for a dozen accounts going in the background and you aren't likely to get six or seven hours out of the iPad.In our experience, it is possible to get close to Apple's claims, provided you're willing to turn off a few features and dim your screen a bit.
