About two weeks ago, Rogers (my carrier in Canada) put through an update which I believe was for 4.4.2 Kit Kat (that is what I am currently showing as installed). About a week ago I noticed my battery life was drastically worse than before. My phone would lose about 4-5% per hour even without being used. My battery info shows that the majority of the use is from Android OS which seems to be keeping the phone awake. That's most likely the reason I am getting such poor life. I saw several posts suggesting I clear the cache and re/re the battery. When I do this, the battery life is much better however this is short lived. Within about 36 hours (including time spent charging) the battery life worsens again. Also of importance is the battery temperature feels warmer/hotter than usual during the high discharging periods (even with the screen off).
What is going on with Android OS that it is keeping the phone awake 90% of the time? There has to have been something in the last update that caused this sudden battery life issue.
This is not an issue of having Wifi, Location Services, or BT turned on. I have a Wifi app that only turns the wifi on when near a known network location, my location services are off, and my BT is always on (however it has never caused excess battery drain).
