You can but it won't be fun
I'm actually thinking a battery calibration app (
like this one) would do the jerb. I'm gonna try it before I do the battery pull method, just for the hell of it. When googling, I found lots of people saying they'd have odd battery issues after flashing ROMs and need to use a calibration app (which I think just deletes a log/db file somewhere). I've never calibrated my battery after ROM flashes and been fine but maybe it finally caught up to me. I did flash this rom the night before last.
