I'm running CM7 on my Thunderbolt, have been for a while now. Battery life has been a ton better than on a Sense ROM, as most of you know. Had my phone on the charger all night, and it was fully charged this morning when I took it off the charger. Now it has seemed like the battery life has been a little bit worse for the past week or so, but nothing like this. Literally 15 minutes after taking it off the charger it was at 19%.
So what gives? I haven't had a chance to wipe battery stats yet, it's on the charger now. Do I need a new battery?
