Good evening,

I'm posting to know if there is some solution to my problem.

I have a M5 note that I have updated recently from stock firmware (flyme 5.2.11.1G) to the 7.0.0.0G, the update goes well but I instantly notice that my battery drain twice as fast than before. Before the update any heavy use (game, video, stream) would use 10%/h, now I'm above 20%/h.
Also I noticed that youtube really heat up the cpu abnormally, the temperature goes above 55°c in less than 15min on it (and have to close youtube before any temperature issue), the temperature post update never went above 45°c.

I found some tuto to downgrade the firmware but doesn't seem to work for me (some file are missing in the official firmware file) and I don't want to be stuck with a phone that I can't even use 4h per day.

So if anyone have a solution, I'll be grateful.

Cordially.
