"Android System" battery drain

[rashadj1]

"Android System" seems to be killing my battery. It's always at the top of my list in the battery usage app. Whereas I see many others have "screen" at the top. I'm only getting about 10hrs of use with a little over 2hrs of screen time. And I see many of you are meeting or exceeding the 24hr mark w/ 5 or 6 hours of screen time. And doing so without disabling all the great advanced features and not running in battery saver mode. I've uninstalled Antivirus. Factory reset. Cleared cache partition. Greenify'd. Disabled all bloatware with Package Disabler. I've tried everything. It's an S7 edge on at&t. Any insight as to what might be causing android system to use so much battery would be GREATLY appreciated.

I'm having a similar issue after receiving the 7/1 security patch.

Yeah its a hassle... and I still haven't really found a resolution. What I can say is I was running Package Disabler and Greenify together and I think that actually made it worse. I THINK (no expert) they were competing with each other and the stock "optimize battery usage" feature and it was causing even more battery drain and overheating. So I started from scratch again and everything seems more stable. But battery life still isnt that great. I get about 10 hours on a charge with about 4.5 hours of screen time. I guess that's as good as it gets for me. Lol

I have the same issue since the latest update. I can literally watch my batter percentage go down every couple of minutes. 1 charge would last normal day from 8am-12am total 16 hours. This morning I unplugged at 8am and by 11am was at 40% remaining with very little use. I have tried everything down to a restore with the same results. Something in this new patch. I sure would like to use my phone without carrying a charger like I did last week and previously.

I had this issue as well, and while this is an older thread, I recently had to factory reset my phone due to issues. After 2 days, the biggest battery drain has been my screen!

I disabled notifications for many apps. that helped me immensely. I was getting Facebook notifications and that was killing my battery. So I disabled notifications for FB and many other apps. that solved my battery drain problem.
