What exactly happened here?
So I'm running CM10.2 and was on one of the newer nightlies (10/02 I think). Basically my phone was being weird and the battery was dying extremely quickly. It got to 2% in about 6 hours so I put it on airplane mode. I checked about 30 minutes later and the battery was at 7%. I thought maybe this might be some battery calibration thing but the night before, my phone died on me (on the same nightly build), thus 're-calibrating' it when it hit 0%.
I'm wondering how this is possible and if it's a battery calibration or software thing.
