I'm not sure exactly what the connection is, but at least once or twice a day my phone will crash, and I have to pull the battery to restart it. Upon restarting, my battery will have lost 10-20% of its life, even if I pulled the battery immediately after the crash. When I check the battery usage, the graph shows the battery level suddenly dropping. It doesn't seem likely, or even possible for the battery to exhaust that much power instantaneously, so I wonder if it is being displayed incorrectly, and if so- if the crash a symptom of the problem or causing the problem with the battery itself. Has anyone else experienced this problem?
