I have a rooted c8633 and factory reset it yesterday, then battery suddenly dropped from 30% to 0%.
1. After turning it on again, the power button wont work(cant screen on/ off) . But i can still use it to power on or force turn off the phone (power + volume up), so i assume its some software problems but i didnt install any apps i never use before.
2. The battery percentage seems not accurate, sometimes it drops fast but some times its very slow.
Could anyone please help with these problems? Thank you.
Sorry i cant capture any screen because my power button is not working.

When i wake up,i just find that my 101 cant open,when i press on the power button,the led light just flash 1 time,then it close...
the battery is full charging...
why it cant open????
P.S i may think that i let it to stay at thr recovery mode last light..
try holding down the power button to see if it shuts down. Then hit the power again to see if it boots properly.
I often have the same problem. When the device goes into standby, I try to turn it on by pressing the power button but it doesn't work:
- Press it once: nothing happens
- Press it again: flashes very shortly and black again
- After that I have to press it several times and sometimes it will turn on. Sometimes I have to reset it completely (press and hold for 10secs)
Really annoying...

Try to set the brightness setting above 30% or more. Most of the time i see that problem is when brightness is set at very low level.

Try keeping your entirely unhelpful comments to yourself. They aren't appreciated. People knew what was meant.

I found the device won't power up properly if you let the power drain out of it to the point of it going into standby and then charging it back up again. The light just flashes at you rapidly. Takes a manual power off before it'll boot up again. If I find my device about to power itself down (1-2% power left), I power it off to stop that from happening until I can charge it up again.
Hello guys, I'll try to be as brieff as possible:
My cousin has a SGS3, which suddenly started showing the power options screen (when you long press power button). Now his phone restarts on its own every time. When you insert the battery, it turns on by itself. If you try to access download mode or recovery mode, it does it but restarts again. I read it may be the power button is not working properly, but I dissassembled the phone and the switch is works normally (it's not broken, either stuck). I read several solutions about clearing cache and stuff, but it just keeps restarting! Like if someone were pushing the powerbutton every time. Btw, he discovered he can turn the phone on and actually stop the phone from restarting if he continously presses the power button and menu button alternatively without stopping (which is useless). When he stops doing that, 3 secs later, it restarts again. Any suggestions?
It's a hardware fault, did you test the button with a meter?
If yes then something else is shorted, to power on when the battery is inserted.

Ah, so this is merely hardware. I did not test it, but now it seems clear something is wrong on the inside (which, unfortunately, I cannot help with). Thanks mate!
Hi,
My phone has a faulty power button and I'm unable to get it fixed. I've found easy work-arounds for it for locking and unlocking the phone. However, I'm not sure how to turn on the phone if it's switched off.
When I connect the charger, even if the battery is 90% it won't turn on on its own...

Nope, the only way I could turn it on was to open the back cover (very painful process) and then press the button area with a pin.
Couldn't get it fixed, so I had to change the phone.
I think there are possibilities in rooted phones, but otherwise the best thing to do is to keep a battery alarm at 30% or more, and keep it on charging whenever you can to avoid a power off. In power on, there are many ways of locking the screen in the MI UI.

Thanks. I installed Blocco Schermo - Simi Studio v.3.21 , a simple app to lock the screen...and when i flagged the option "show in notification area" , the problem magically disappeared.. The Power On/Off button started to work again. I think it was an hardware problem (because the problem has come up after the phone was at the sunlight for hours in my car and went very hot) but now i think it's obviously a software problem.
Hi guys, I got the same problem too. Unfortunately, I drained my batt while playing games. So the problem now is I can't turn it on. Any idea how to turn on the phone without using the power button?
I solved it
Hi guys i solved a problem! You should hold main button + down volume button for 10-20 seconds. Then, when MI Remote opens, stay on the reboot and wait about 3 minutes, then stay on the reboot systems as well. Great work!
just change the volume flexible. its also not took much cost.
My HTC 816 turns off / shuts down after screen time out. After time out if you let it ideal for 5-7 seconds and then try to wake it up by pressing the power button, you will have to long press the button and the phone will boot.
I also noticed it turns of completely about 80% times and 20% times it restarts.
Other interesting thing i noticed is that if the phone is plugged into a power source it wont turnoff/restart, it will behave as it should.
Also if you are on a call, and the screen times out it wont turnoff / restart.
I guess the problem comes when the phone is left idle.
I have tried factory reset, clearing cache, booting in safe mode, nothing works.
Battery is in very good condition, no fluctuations gives very good backup.
Hello!
