I've noticed sometimes, but not always, with CM7 on the latest nightlies (running 2.3.4) that my battery will just drop like a rock if I leave it off the charger overnight. Normally I would expect that sort of thing to happen if I have a wakelock with some kind of process on the phone. But every time this happens, and I check battery use and Spare Parts, there aren't any issues with wakelock. For instance, this morning I woke up and my phone was dead. When I went to bed, it was somewhere in the mid 40's for my battery percentage remaining. I have no idea what would cause this. I've noticed this with both Tiamat and SavagedZen. Is anyone else seeing this happen? I've checked my CPU usage too with CPU spy and it always seems normal too with the appropriate time spent in "deep sleep" and time spent at regular clock speeds seems to correspond with my awake time. So I don't think it's an issue with the CPU being pegged somehow.
