I'm having issues with my battery draining overnight. I'll go to bed with 90%-100% and wake up with 20% battery. When I look in the battery history, I find the phone has been 'running' for all that time and the Wifi has been 'Running' constantly as well. I have the Wifi set to sleep when the screen is turned off. If I look into the Partial wake usage, there is no indication that anything has been keeping the phone awake or 'running'. The top app is 'Android System' and it equates to about 1% of the running time. Does anyone have any ideas how I can track down what is keeping the phone running as spare parts+ is not giving me any indications on what it could be. I've just tried Watchdog lite and no indication from there either.
