Hello guys, i wanna ask u a question. After i Power off the phone and leave it for about 4 seconds, it will turn on again itself. I tried Factory reset, wipe cache and all of this things still the same thing. Any help?

No, power button is just fine. It was the other day, i download an app for watching free football games, and after that everything was disaster. I run numerous factory resets, wipe/cache clean, and even i run a scan with anti-malware but still nothing. I suspect that it might be the battery, but i'm not so sure. And yes, if i turn off my phone and has 72% of battery, when i turn on again it will have from 8-15%.

And btw, thanks for replying man
