Seems like my 3T does not turn off when I turn it off via pressing the power button. When I have a charger connected it's easy to spot when the vibration goes off, but the charging light keeps lit - even when I remover the charger. It's also apparent that the device won't turn on when pressing the power button for three seconds. I need to press it about eight secs and then another two to turn it on.
Turning off works when rebooting the phone and turning it off from the bootloader (my device is unlocked) or when turning it off at the pin entry (have boot pin set).
Can anyone confirm?
Tested with clean system (no root, no Xposed) and still happening...
Turning off with the power button works on my device, powering up DOES take some time, 5-8 seconds of holding the power button down.
Seems like forever holding that power button!
Maybe I need to be more precise. Yes, I can "kill" the phone just holding that button for about ten seconds. But that's not the point. I suspect it does not power off properly.
To test, hook it up to the charger. Press power for about three seconds. Select "Turn off". Wait for the phone to vibrate. Charging light is on. If it'd be powering off correctly, it would kind of turn on again to show you the charging screen (battery symbol, then dash symbol). Does not do this for me. Instead it sits there... black. When I remove the charger, the charging light stays on.
To turn the phone on again, I then have to press power about ten seconds (turning it off), and then again to turn it on.
I tried your exact method, and my device shuts down (connected to the power cord, plugged in) normally, and them restarts while holding down the power button in 3 seconds.
When not connected to the dash charger, my device does power down very slowly as described in my earlier post (stock kernel)
My devices is rooted with the blue spark kernel though--so maybe that has some baring in my "normal" shut down/startup behavior.
I have the same bug to you... So I disconnected the cable...
Just wait for the future updates....

When I disconnected my phone from the charger this morning the LED did not shut down. The phone does not respond, now several hours later the green LED still is on (solid green). the buttons on the screen is lit but the screen is black. If I press and hold the power button the buttons on the screen starts to blink after a few second, but nothing happends. The same if I try to do a hard reset by pressing vol-down and pwr button. Nothin except the blinking from the buttons on screen. If I try to connect the phone to a computer nothing happends, the computer does not find the phone. If I try to call the phone notheing happends....the phone was turned on when connected to the charger.
Any idéas?
Problem solved, after2,5 hours the LED shut down and I was able to reboot the phone.
If you keep the power button held down for 10 to 15 seconds it will power off, because you can't pull the battery in this device HTC built in a power down feature to the power button

Have a Samsung Galaxy Tab (Verizon) SCH-I800 7" that is stuck in a reboot loop. Searches/fixes for this issue seem almost common, but mine is experiencing this issue much worse than the others I've read about. Full charge, not plugged in; without pressing the power button, the device automatically attempts to turn on, the Samsung logo appears for 5 seconds exactly, it shuts itself off, the process repeats until the battery dies. Battery at all levels, plugged in; without pressing the power button, the device automatically attempts to turn on, an empty battery image displays for roughly 4 seconds and then a full battery (or current level) displays for roughly 1 second.
The 5 seconds while it is on, pressing or holding the power button has no affect. Pressing and holding the power + down volume buttons will display the yellow downloading screen, which displays "downloading.... do not turn off target" and yellow android sign for 2-5 seconds (depending on how quickly I am able to load it". While this downloading screen is displayed, pressing power, volume up or down do not have any affect.
When connecting the Tab device to a computer via the USB cord, the computer recognizes it for approximately 4-5 seconds, then disconnects for 4-5 seconds, repeat forever. The computer is unable to successfully install drivers or do anything useful in this short amount of time. The battery has been replaced as well as I thought that may be the issue, no change.
Any suggestions?
"Pressing and holding the power + down volume buttons will display the yellow downloading screen, which displays "downloading.... do not turn off target" and yellow android sign for 2-5 seconds"
are you saying it turns off after few second even in that download mode?!
what have you done to your phone before that?
are you on stock firmware? version of ROM?
even tho i don't think i am able to help you, but more info my give someone else a better chance on doing so

well, i have experienced this, after i flash a ROM, and my battery is low, i forced it to flash, and became the same like your tab....
maybe this step can help your tab...
1.charge your battery for 3-5 hours
2.after that, quickly hold the power + down volume to download mode
3.connect it with your computer, Restock it
PS: IF after step 1 try to normally boot your tab, maybe there still a hope:angel:
So basically my wife's phone has a broken power button, with the few times it's been turned off she just plugs it into the charger to start it and it boots up, so this time it went to the TurboPower screen and now it's just stuck there because without a power button it won't turn on or go past the TurboPower screen.
So is there any other way to exit TurboPower other than the power button? I'm going to try leaving it for an hour in hopes it just leaves by itself but I have doubts that will work.
Poco M3 Pro 5g
Stock rom
Locked bootloader
It was powered off for some time because I had to replace broken display
Now when I try to boot a battery icon appears and then it turns off. Same thing happen when I plug in the charger
I repair smartphones professionally so I am sure no hardware damage during the repair

I went through it. try holding the power button, connect the cable and only release after the battery shows 1%. you can try holding the power and volume + or power and volume - buttons too instead of Power button only, in the same way. alternatively, you can leave it on the charger for hours and it might turn on. Make sure you are using the supplied xiaomi charger
If I plug the cable or I plug and hold the power button the phone just tries to boot continuously showing the battery icon and then turning off and repeat, nothing really happens
Is that what is supposed to happen?

Yes, It happens. Luckily the phone will reach 1% and charge normally, keep trying
You actually saved me, it worked in the end, after some loops it booted alone, all I had to do was just let it sit there, didn't even have to keep power button all the time, once it started the loop I just left it there and when I came back it was booted.
My device was working fine it turned off all of sudden and it wont turn on again.
There was around 70% charge remaining.
No display while I connected it to charger.
No display/Vibration while pressing power button.
No display while pressing Power + vol down/ vol up
Only The red LED is on even when it's not connected to charger. its not blinking. its steady.
When I long press the power button for around 10-15 seconds, the led turned off and on after a second. still there is no display.
I tried to keep my mobile in charge for more than 12 hours. Still not turning on.
I would appreciate any help to revive my phone.
