Have to agree here. I had a situation where the battery would drop quickly to 40% then sit there for hours and hours before continuing down to single digits. Charged to 100%, unplugged and left unplugged for a couple minutes, then plugged back in. Rebooted to recovery, wiped battery stats, then used the phone until it was drained. Recharged overnight, and from that point I had a linear progression of battery depletion. Or in other words, the battery numbers made sense after that.
