Found this solution @ precentral - http://forums.precentral.net/palm-pre/216398-solution-improved-battery-life-after-1-3-1-a.html says to change PRL to 60657 and drain battery to 0% and recharge and should be fine
here's a solution from Palm direct from a chat we had: 9:02 PM Steve: PLease run interactive test on device while charging the device. 9:02 PM Steve: Open the Launcher and tap Device Info. 9:02 PM Steve: Tap More Info. 9:03 PM Steve: Tap on top left corner of the device screen. 9:03 PM Steve: Open the application menu and tap Interactive Tests. 9:03 PM Steve: Select the test to run. 9:03 PM Steve: Once the test is done, please restart the device and then you can charge the battery for 2 hours and that will solve the issue. 9:04 PM Steve: Press and hold Power and slide the Ringer switch three times to restart the phone. The phone may take a few minutes to restart. 9:09 PM me: so what you are saying is by running the tests and then restarting the phone it will be fine? 9:09 PM me: how does running a test help? recalibration? 9:10 PM Steve: That should work fine as many of our customers solved the issue.
