iPad battery life impresses, lives up to Apple’s hype
[Via Edible Apple]

Promises of long battery life on tech devices tend to be looked at with skepticism. And rightly so. Often times, when a manufacturer says that such and such a product can run for ‘x’ amount of hours between charges, the fine print typically mentions a few caveats, such as screen brightness turned half way down and wi-fi being turned off.

Over the past few product releases, however, battery life on the iPhone and iPod Touch has not only lived up to the hype, but has often exceeded it. The iPad, it appears, is no different.

Apple today lifted the veil of secrecy from the select number of reviewers it let take the iPad for a spin a few days early. Overall, every pre-release review is overwhelmingly positive, but one thing we found particularly compelling were reports of just how long battery life lasted on the iPad.

New York Times reviewer David Pogue wrote:

Speaking of video: Apple asserts that the iPad runs 10 hours on a charge of its nonremovable battery — but we all know you can’t trust the manufacturer. And sure enough, in my own test, the iPad played movies continuously from 7:30 a.m. to 7:53 p.m. — more than 12 hours. That’s four times as long as a typical laptop or portable DVD player.

12 hours of battery life while running non-stop video? Are you kidding me?!

This may be the item that makes the iPad a real breakthrough device. If it actually can be used for ore than 10 hours in its most power hungry state. From the discussion, the ability to maintain large amounts of computing power while also using very little battery power may be “tantamount to witchcraft.”

It may very well come down to the A4 processor Apple uses. This proprietary chip is something that may very well give the iPad some of its ‘magical’ qualities.

And it may be something other’s who hope to copy the iPad will have a hard time copying, especially without going up against the obvious patent positions that Apple will have in this area.

Low weight, high power computational ability, low battery requirements. Part of what makes the iPad a tough item to copy.
