    The past three ROMs that I've used - Cyanogenmod 6.1, UD 2.4/5, and now BB 6.1 - my battery has behaved very erratically. There has been a lack of consistency in drain times; for example, one day I talked on it for nearly 3 hours (total, not all at once) and the screen was on for nearly 2 hours, yet the battery was only at 40% when I got home. The previous day, I talked for 15 minutes and only listened to [locally stored] music, yet the battery was at 20% after less time.

    On top of this, about 65% of the time, during discharge it will skip 30%. Once it hits 20 and I plug it back up it is back up to 50% or 60% in a matter of minutes.

    I'm not certain whether this is a device problem or it's just time for a new battery. Thoughts, suggestions, comments?

    When you flash a lot of roms you'll need to wipe battery stats occasionally.

    seriously i've only seen this problem pop up on android 2.2. i've been a user since the G1.. this is really frustrating.

    once i did a battery pull and it seemed to fix it, but it went right back down to 20% once i sent a text message. wtf?

    its either a bad battery or you need to calibrate it again. did you install bb on a full charge or plugged in?

    From my understanding you do have to let your phone completely die, there's a hardware aspect of it that can only be reset by doing that, wihich I did today actually, my battery had an x on it for about 3 hours, 1 of those being complete navigation use, overall latest bugless lasted about 16 hours mild - moderate use (2 1/2 hours navigation)

    I deleted my battery stats this morning after a full night of charging. I took it off charge at 6:30 this morning - it's now 4:00 PM and I have 5% left. Should I expect this to get better over the next few discharge cycles?
