While the PlayBook itself has received a mixed bag of praise and criticism, RIM has been lauded for making good on its promise to update the PlayBook OS early and often. It appears, however, that there has been an unwanted side effect to those updates: decreased battery life.
PlayBook users have been reporting the problem since installing the most recent update, which brought expanded BlackBerry Bridge apps and video chat to the tablet. According to RIM, part of the problem is that some of the new apps may run in the background post-install until a user taps through and accepts any license agreements. RIM also suggests that users who have experienced the problem try to condition their battery — by letting the device deplete its charge and then fully re-charging it several times.
Another thing to check is under your PlayBook’s general settings. If your Application Behavior is set to showcase (which keeps applications in an active state when they run in the background), that will have a definite impact on power consumption.
Somewhat curiously, it’s also been commented that PlayBooks with higher internal storage capacity are yielding longer battery life. Of course, that’s according to reports from “some users,” so it’s hardly a clinical examination and the statement should be taken with a grain of salt.
