Why does my phone use 4% per hour on airplane mode instead of 0.5% per hour like it used to? According to GSAM Battery Monitor, 65 % is "App Usage". Of that, "Kernel (Android OS) takes up 35%, and "Google Services" is 12%. It says it was kept awake nearly the whole time. I'm fresh on my 3rd refurb, 4.3 update, and factory reset after that. I want answers. Not "it's probably some app, so just factory reset and slowly add apps to see which it is", or "order another replacement". One of my favorites is "pull the battery and boot it up". I did that yesterday and after 2 hours and it down to 93%, it only dropped only 1% in the next 3 hours so it was temporarily fixed. This is not acceptable!
