Analyst expands on the reason behind the poor battery life of the BlackBerry PlayBook
Recently, we reported that Kaufman Brothers analyst Shaw Wu had switched topics from writing about a Verizon branded Apple iPhone to claiming that the BlackBerry PlayBook suffers from poor battery life and that the launch of the tablet would need to be delayed. To refresh your memory, Wu's earlier analysis said that the BlackBerry's tablet had been getting only 2-4 hours of life in early testing as opposed to 6 hours for the Samsung Galaxy Tab and 10 hours for Apple's iPad. RIM blamed the short cell life on the fact that the units tested were beta versions without any power management and optimization of the battery.

Today, Wu has broken down his claims about the BlackBerry PlayBook's  battery problems into 3 reasons why he still believes that the tablet has a cell life problem. Reason number 1 was one that the analyst had previously written about. The QNX software that RIM is using for the tablet was designed to run in products that are using power from a wall socket or a car battery. The OS was not intended for use in a mobile device where battery life is limited.

Another reason for the tablet's poor cell life is the use of the power-hogging Adobe Flash in the browser. As Wu wrote to his clients, "As seen in recent tests for the new MacBook Air, use of Flash can cut battery life in half….From our understanding, the poor battery life of early PlayBook units may be due to its incorporation of Adobe Flash."

The third and last reason for the Playbook's short battery life is that RIM's history of using power management in its devices is not as extensive as say, Apple's is. With the Apple iPad using its own homemade processor, Apple has a chance to build-in better integration of battery life into the product.

RIM responds by saying that they are producing a tablet that "offers superior performance with comparable battery life." Considering Wu's track record of incorrectly predicting specific dates that we were to see the Verizon branded Apple iPhone by, we should give RIM the benefit of the doubt and wait until a final version is launched before coming to a conclusion on the strength or weakness of the BlackBerry PlayBook's battery life.

I still think Wu is shooting in the dark. Applause to PhoneArena for seeing the bigger picture in all this too.

i dont know why they even print this. if an anaylist was doing anything more than shooting in the dark to get some personal press attention, they would be making a lot more money on insider trading and such. i run flash on my vibrant and dont have any more noticable battery drain than when i was on stock software. its more battery/ power implimentation. If blackberry says they can fix it (since it hasnt even been integrated yet), then id believe them. they may be behind the curve when it comes to smart phones, but they generally make a high quality product.

Really? That's the picture you use? They have had actual pictures of this thing around for months now, and you use a crappy, doctored iPad mockup?

Funny. Apple uses a specialized die of a cortex a9? This guy's seen what power management features have been built into the Playbook, or what development was at hand before RIM bought QNX? And flash? A possibility, if they dont have an 'on demand' click to activate the plugin a la android. Its kinda funny, but putting up 'pot shots' like this without any sort of newsworthiness/verification is sheer stupidity. And using the horribly photoshopped ipad picture is stupid. For a while now, I've not been with the "Phonearena is a bunch of Apple Fanboys" crowd. But I gotta say, this completely turns me off from even going to this site. Also, if I wanted to read an abbreviated version of I'd go there. heh.

WTF? what drugs is Wu taking. 1. With proper programming and power management controls, QNX can be made to do what ever RIM wants it to. 2. Adobe flash is going to bring down the RIM Playbook?? Sounds like this guys is just an Apple fan boy, I mean, flash isnt going to be working 24/7 on a tab, and not every single web page has flash content, and I'm sure RIM has worked out a way to disable flash content to save battery if it does chew a little. It should also be noted that every android 2.2 phone and tab out there has flash, and its not as power hungry as Wu is pointing out .. 3. The Apple CPU technically isn't home made. Its made by people who know how to make CPU's, subcontracted out by Apple, and its essentially a Cortex A8 (just with different labelling!). Power management can be software/OS controlled - so forks to Wu again. Based on his track record, it sounds like Wu needs to get another job - can I suggest, maybe predicting the weather, or predicting whether the sun is going to rise tomorrow morning at about 6am....

It seems to me that Wu is Apple zombie follower that is trying to inject fear in the consumer market about this new product that may pose a serious threat to the Ipad market.
