Is anyone else having problems with excessive battery drain after updating to the new version? Also has anyone experienced software update issues such as missing icons when updating BBM and Facebook for the App world? It's like they are not compatible with that version? I am getting so ready to get a different phone. I love my BB but i have to most issues with my 9650 either with battery drain, lag, crashes, and even design problems (touchpad flaking and paint chipping on keys).
With the info that you provided I would probable recommend backing up your device with BDM and giving it a hard reset back to factory reset. This will clear any thing in the OS that is causing it to act erratically. Reload the service books and then slowly add any applications you may be using to try and identify the battery draining culprit.
