Something very odd there. I get battery life like this. Exynos processor:
Here are some things I did.
Cleared system and app cache which you already did.
Turn off always on display
Turned off Google location history.
Doing that got me from 7 to 8.5 sot.
I'm getting 7 hours sot
I did a few tweaks to get it:
Turned off always on display
Turned off Google location history
Hmm I thinks that's it. 7.5 to 8 hours sot most days of heavy use.
Lol. Well I wasn't going to admit it but I did the same stupid thing. It still works fine. I bet there are a lot more people that did that and aren't admitting it. 😀😁
I had that on one of my S7 edges (Wifes). It'''s a hardware issue. Took it back to carrier (Bell Canada) and sent out for repair and gave loaner phone. It is now fixed after a week. Just waiting for delivery.
