This is not another battery thread.
This is just one question:
Until today i had awsome battery life... But today i noticed some weird things. When i go to my battery statistic i see that android system is biggest consumer, what was not case few days ago. I havent installed any new app..
Here are screenshots :

Battery jumps way too much

Hey guys, I recently purchased a Note 8 and have started noticing the worst battery life. While I play a game like Carmageddon, suddenly the battery will drop steeply. And sometimes, when charging, it'll rocket up to 100% without any explanation whatsoever.

Hello Everyone. How's your Note 2's battery life?
Well, here's mine fully charge with 3G on whole day. This is the best result I could get I think?
In between time, I've turn on my hotspot sharing my 3G.
Anyone may drop some comments, or giving helpful battery saving guide
TQ
