May 26, 2011, 4:41 PM — When I first started using my BlackBerry PlayBook tablet about a month ago, I was impressed that I could get through nearly an entire day of moderate-to-heavy use--non-stop e-mail and messaging, frequent browsing and checking my social networks, along with the occasional streamed video or audio track.
But today, my PlayBook battery has significantly less life per charge, and that seems to be largely due to RIM's latest BlackBerry PlayBook OS update. (RIM has acknowledged that PlayBook OS v188.8.131.528, the most recently released PlayBook OS, can cause users to experience a substantial drop in battery life than previous OS builds.

Until RIM releases an updated PlayBook OS to address the weakened battery life in the latest tablet software, PlayBook owners experiencing battery issues will mostly just have to deal with less overall tablet life.
Thankfully, a number of measures exist that you can take to help boost your overall PlayBook battery life. Even if you're among the lucky few owning a PlayBook not exhibiting any negative affects from the latest PlayBook OS, the following battery tips and tricks can still help you get more life out of your tablet.

Disable PlayBook Wireless Radios When Not In Use
Though the initial version of RIM's PlayBook is Wi-Fi only, meaning it does not currently pack a cellular radio, the tablet does have Wi-Fi and Bluetooth radios. One of the simplest ways to conserve PlayBook battery is by turning off these radios when they're not in use.
Unfortunately, you'll need to leave Bluetooth enabled at all times if you wish to access your BlackBerry e-mail and PIM applications via your BlackBerry smartphone and the BlackBerry Bridge application. (Read more about BlackBerry Bridge here.)
