Up until today I've been getting ok battery life(not great, but good enough to get through the day without a charge). Today I took my phone off the charger at 6:00 and it had 100% battery. By 10:00 (4 hours later, not 15)it had no battery left and turned itself off. In those 4 hours I texted for 5 minute, talked on the phone for 1 minute, and used Facebook for 2 min. The rest of the time it sat with the screen off in my pocket. I have Watchdog and it didn't notify me that any apps were causing problems in the background and I had a strong 4g signal. I am running Das Bamf 1.7 with the default kernel not overclocked with the on-demand governor. Why has my battery life been fine(12 hours, medium use) and all of a sudden gone to hell(4 hours, light use)? Any ideas?
