Battery Life. All that power on the new iPad means nothing if the battery life gets drained in 4-5 hours.


Unlike other mobile device makers, including Sony and Nintendo, Apple is acutely aware of how important battery life is. The iPad 3 has the same 10 hour battery life as the previous two models.


I'm almost certain you won't get anywhere near ten hours of playing Infinity Blade. Some things take up more power than others - games are near the top of that list.

You probably don't really care, but I was curious, so I did a little test. I played Infinity Blade 2 on my iPad 2 for a little over an hour at medium brightness, medium volume. The battery dropped 12%, which suggests it could keep that up for more than 8 hours on a full charge.

Now keep in mind that my iPad is almost a year old and sees heavy use. My battery has some miles on it. It's quite possible that a fresh iPad battery could maintain that usage for a full 10 hours.

In my experience, the big draw on the battery in these devices is the backlight behind the screen and use of the wireless radios, not the load on the SoC. An iPad doing nothing more than sitting on a home screen will burn through its battery in a little over 7 hours at max brightness. In contrast, an iPad idling  at lowest brightness will last almost 20 hours:

How does that drop in battery life compare to when watching a video for example?

You could be right, I don't own a tablet and was just basing my opinion on my experiences with my laptop's battery life.
