[Ars] RIM PlayBook tablet's performance comes at a cost

post #1 of 10

Analysts may have located the future BlackBerry tablet's weak spot: battery life. According to Kaufman Bros. analyst Shaw Wu, the BlackBerry PlayBook currently in the works at Research in Motion suffers from a battery lifespan that can't compete with the tablets it's designed to take down, including the Samsung Galaxy Tab and the Apple iPad.

According to All Things D, Wu's sources have told him that the PlayBook currently only lasts "a few hours" per charge. For comparison, the Galaxy Tab lasts about six hours, and the iPad has significantly more screen space yet churns out more than 10 hours under moderate use.

A "few hours" in my mind means about ~3...being generous, 5. Still way too short to be worthwhile.

Better be a decent price then. I was considering one of these if the price is right...

Pity. Hope it's a software thing and not a hardware thing. If it's hardware, that means Tegra 2 devices are going to all suck on battery. You'd need a 10" tablet to fit a decent battery in there.

This is likely due to the nature of the operating system the PlayBook uses, called QNX. QNX was designed for other systems that are perpetually plugged in, like network equipment or interfaces in cars, and isn't optimized for maximum performance on a minimal power source.

As in, that's what they are thinking it may be, but there is no concrete proof.

No need to be argumentative. It's pretty obvious that's the reason.

Argumentative? Obvious? I think neither of those comments are fair. My comment was merely pointing out that the source didn't prove that that was the reason. If that is argumentative, then not sure what I can do about that. As for obvious, well, since we can just look at the abundance of Tegra 2 tablets battery life with the kind of parts that the high end manufacturers use to judge the battery life, it should be obvious right? Except, there are none. Even the Advent Vega is merely rated at 6.5 hours with screen on and its much larger 10" screen to put a bigger battery behind.

Okay okay, settle down bud. No need to fly off the handle.

Everyone knows Tegra is a fairly battery-friendly mobile cpu and expects more than "a few hours" worth of time out of it. It's fairly clear from the information at hand that software is to blame (it usually is).

Blackberry should just give up and switch to Android. Port BBM over and run their own flavor of Gingerbread.

Right now Blackberry is a joke. The Blackberry Torch costs more than the iPhone 4, and has the same specs as a first gen Android phone, with an OS that is as outdated as WinMo 6.5 and Symbian.
