Early Reviews for the iPad Are In: Battery Life Better Than Expected

Posted by | 03/31/2010 | 3 Comments

Both Walt Mossberg (Wall St. Journal) and David Pogue (New York Times) have released early reviews of the iPad. Both are filled with some interesting information after a week or so of testing, but I think the big news from the two reviews is that both report the iPad battery life is longer than the 10 hour claim of Apple.

Mossberg says:

I was impressed with the iPad’s battery life, which I found to be even longer than Apple’s ten-hour claim, and far longer than on my laptops or smart phones. For my battery test, I played movies, TV shows and other videos back-to-back until the iPad died. This stressed the device’s most power-hogging feature, its screen. The iPad lasted 11 hours and 28 minutes, about 15% more than Apple claimed. I was able to watch four feature-length movies, four TV episodes and a video of a 90-minute corporate presentation, before the battery died midway through an episode of “The Closer.”

And according to Pogue:

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.

The overall tone of the reviews still contain a lot of wait and see. Pogue breaks his review into two, one for techies and one for normal folk. (At least he didn’t do a song.) Mossberg seems more taken with the potential than Pogue does, but you can gauge all of that for yourself.

I think I need to get one of those professional reviewer gigs so that I can spend 11 to 12 hours a day watching movies and videos.

UPDATE: PCMag’s battery test yielded 9.25 hours.

UPDATE: Andy Ihnatko of the Chicago Sun-Times has posted what he says is the first part of a five part review. USA Today calls it a winner. Xeni Jardin of BoingBoing calls it a touch of genius.

UPDATE: Stephen Fry weighs in with his admittedly fan-boy approach in Time Magazine. Melissa Perenson takes a look for the Washington Post.

    Very nice battery life numbers. Now for some other company to make a less bottle necked tablet with an ARM chipset. (ADAM??)

    I guess well know soon enough when GBM or user reviews start flowing in but I just dont see how 12hrs video life off that battery and screen is possible.

    If it is it certainly puts tablets to shame and will certainly bury HPs tablet attempts.
