Hello, I have been searching for a solution without much luck.
Summary:
When the device is off and the charger is connected, the device does a complete boot up (ie: system starts up, goes to home launcher and tablet is completely useable as normal). If the charger is still connected and I try to power off the device, it will turn off and on again (essentially a restart)
Expected behavior:
If the device is off and the charger is connected, the device should do a soft boot and display the battery/charging screen only.
Other notes:
I am on the latest update (Android 11) and rooted with magisk. Tablet has been in use for a few months now. This only started happening recently and I don't recall making any changes.
I tried flashing the latest firmware on top using ODIN (although imaged was patched with magisk and data is preserved) but this didn't help.
I also have tried different chargers/cables and problem remains.
Searching online, I see people trying to power on their devices when connected via charger/USB without much luck. For me, the problem/question is reversed!
Any ideas/suggestions other than a complete/clean wipe with stock firmware?
Thanks
Small update, removing root and uninstalling magisk fixes the issue. Flashing magisk back causes the issue to appear again.
Still not sure why the problem didn't occur before as the device has been rooted with magisk for months now and magisk has not been updated since.
Oh well, I do need root enable so back to the drawing board again.
Success! Flashing TWRP fixes the problem. Still, doesn't explain why the device was working fine for a few months with stock recovery and why it suddenly changed in the last week.
So to summarize in case anyone else is interested on a device using stock Android 11 firmware and the device is powered off:
Magisk with stock recovery: Device will power on when charger/usb is connected.
Magisk with TWRP: Device will run in low power mode and display the charging animation screen.

Hi,
I'm having this problem for a while and don't remember exactly how it occurred, if I remember well, it started happening after flashing a non-stock ROM with CWM, but can't really reproduce it.
Current CWM is Cyanogen CWM-based recovery v5.0.3.2. The problem persisted even when upgrading the ROM to 4.2 (PacRom).
Anyway, as for the problem itself, when I plug-in the device to charger while its off, I see a legacy loading star similar to this one for like 5 secs, then comes up the battery icon for a couple of seconds, and device is turned off again for another 3 seconds. The whole routine repeats over and over infinitely.
Note, that the device warms up during the charging process while it's turned off.
How to solve this?

Afaik, this behavior is normal. When the device is off and you plug it in via a wall charger, it's fine; it boot's up and shows the battery charging icon. However, if you plug it in via a USB port on a computer, you enter an endless boot loop.
Afaik, the only solution is to charge the device via a wall charger, or turn the device on normally and charge via any source you want.
Note: I have flashed back to stock just to test this and it behaved the same.
Note: Jelly bean roms seem to have an additional issue where, when you reboot the device while it's plugged in (any source), the device goes into the "charging only" mode. If you are plugged into a USB port then you end up in the above mentioned boot loop. The solution to that is to simply unplug the device before rebooting...
I'm havin problems with offline charging after i installed cm11. I've tried change kernel and change rom (i'm using PA rom now) and i'm still with the same problem.
When i plug the charger on my phone while turned off, it shows a battery icon with a question mark on it and i think it's not charging. Is this a general problem or did i make something wrong?
Try keeping it plugged in. See if it charges or not.
Also,did you change your bootlogo?
I didn't change my bootlogo. it boots motorola bootloader and then shows the battery icon with the question mark. I left my phone charging this way for a couple of hours and tried to turn it on. my phone booted with 0% battery and then shutted down, so definitely it is not charging. other thing I notice is that when my phone enter this buggy offline charging mode, I have to press power button + volume down to reboot my phone, it kind of get stuck in this mode when my phone enter it
Try using a different charger.
It doesn't seem to be a common issue.
Can you power up the phone whilst charger connected.?
I've tried two different chargers, one of my Moto X and the original one. If I want to charge the phone I need to turn it on first and then plug the charger. I can't turn it on with the charger on cuz it is stuck on that screen with the battery icon
I'm starting to think I've done something wrong. I did the following to get where I am right now:
I was on stock firmware, so I rooted the phone and installed the newest version of SS. Then I downloaded cm11 and gapps and copied to the phone. I entered the SS and wiped everything. After that I installed cm11 and gapps.
When I discovered that issue I've tried install JBX kernel to fix it and nothing. then I wiped everything again and installed PA rom + gapps and still that issue. Did I do something wrong?
No, you didn't do anything wrong.
Since its persistent across both ROMS, its not a ROM issue either.
In my opinion, its most probably a problem with port or the board. The port doesn't deliver enough power.
You can try flashing the stock ROM back, it might repair in case something s/w related is corrupted. If it doesn't work after that, then its a h/w glitch for sure.
just in case, if I install stock rom and the problem goes away, what might be causing this problem?
I can't re-flash stock rom because I can't charge my phone and I can't boot into the rom or recovery. I don't think fastboot charges my phone. I just realized that bootloader is locked. Maybe this is the problem, isn't it?
it isn't a h/w glitch because before cm11 it was OK to charge offline
You'll need a factory cable to flash in case your phone has insufficient power.
Look for it, there's a guide about making one in the general section I suppose.
No need, I've managed to charge the phone through USB on my pc. When I plug the charger on my phone, that glitch happens, but when I plug the USB on my pc, the phone lights up a white led and apparently it charges the phone (slower, but charges). That's really weird. I really want to know what is happening to my phone
Hello,
I'm using GT-i8552 stock 4.1.2 (UNROOTED).
I did root my phone with 'Framaroot', the rooting was successful and SuperSU was installed properly. After this I didn't try installing any custom ROMs or any conflicting apps but still I started facing battery issues like,
1. After putting on charge, display shows that it is charging but no progress at all (it freezes at certain %)
2. When the phone is switched off and put on charge, the display just blinks up and goes off (lights on lights off) nothing else appears and no battery progress
3. Sometimes the phone charges properly to 100% but after disconnecting cable, battery status is 50-60%
The above problems occur not all the time.
The things that I tried,
1. Did unroot my phone and removed SuperSU
2. Did a factory reset from phone's settings option.
3. Got an original new battery from service center
4. Took the phone to Samsung customer care (they couldn't find any problem at all and advised that the problem must be in the charger) (I tried to charge with samsung charger, sony's charger & portable charger)
5. Changed USB cables for charging
6. Tried Battery Calibration apk by Nema
7. I think the charging port is little bit damaged but I can still get the phone to charge
Even after doing all the above things the problems still occur sometimes. Other than that the phone works fine, there is no BOOTLOOP.
When I try to boot it into recovery mode (volume up+home+switch on and release after SAMSUNG logo) but after releasing the buttons the SAMSUNG GT-i8552 logo appears and phone starts with no warning and all, it's not accessing the recovery mode or download mode too.
Is there any solution to the battery related issues or do I need to flash the stock firmware again?
I am not aware of the steps of flashing firmware, please do redirect.
Thank You!!
I flashed a MARSHMALLOW v014 on my COOLPAD NOTE 3 mobile phone , then flashed twrp 3.0.1 and supersu 2.4 in order to root my device to open it for large scope but unfortunate occurred. Initially when I flashed supersu in twrp recovery it installed and device was rooted as shown in root checker but later after 10 min of doing this suddenly my hardware power and volume button stopped working and even my device was not charging when charger was Connected I don't know what went wrong in OS, bootloder whatever but how to tackle with these kind situation in order to save my device, as when it's gets off after draining battery totally neither I can't charge after turning off nor can boot using power button and not even I can enter in recovery mode how to save my ANDROID
:crying:
How I bricked (and unbricked) my tablet SM-T820 due to OEM Unlock setting and battery drain - I hope this is useful for someone making the same mistake! I successfully rooted my Tablet S3 T820 with TWRP 3.2.1-1 and Magisk and installed SM-T820 Tweaked without any problem the moment I received it - it's a great daily driver!
While fiddling to fix an app crashing due to safetynet issues, I unchecked OEM-Unlock and forgot about it. The tablet ran out of power and upon reboot gave an FRP boot error "Security Error: This device has been flashed with unauthorized software & is locked. Call your mobile operator for additional support...". Any attempt at booting into TWRP was FRP blocked I guess because of the locked Bootloader. I immediately tried doing a stock firmware restore etc. via ODIN which failed at about 65%, probably due to a low battery (which I didn't know as there was no way of seeing the battery status). Upon reboot I had a screen saying "use the emergency recovery function in the smart switch PC software". When I tried reflashing stock firmware through Odin again, the tablet connection kept disconnecting/dropping out every 10 seconds or so and restarting always going back to the same “use smart switch” error message. The same happened in Download mode. I now know this was due to a drained battery. I couldn't power off the Tablet in order for it to charge as it always switched on as soon as power was connected.
The fix: I noticed when in the error boot screen "use smart switch to recover" it didn’t charge at all (I had it plugged in for 8 hours) and always cut out and rebooted to error msg. every 10 seconds. The first time I managed to stop it cutting out was by booting into Stock Recovery Mode with "Home & Vol+ & Power" buttons while plugged into the wall socket (stock recovery must have installed just before Odin failed the first time I tried to unbrick). I had it plugged into the wall socket in Recovery Mode for about 2 hours where it very slowly charged a tiny bit. In stock recovery I booted into "Reboot Bootloader" where it went directly to Odin Mode saying “Downloading... Do not turn off target”. I then reflashed my firmware without any errors. After first boot the battery was still only on 1%! I again have a brand new, functional Tablet! Now back to Rooting . . . and never touching oem-unlock again!

Are you using the latest Odin? 3.13.1 I think.
