[Q] Phone automatically turns on when connecting it to charger

I have never had this issue before, if the phone was off and I plugged it in to charge it would stay off and charge and if I pressed the volume it would show a image of a battery being charged. Now when the phone is off and I plug it in the wall charger it turns off, if the phone is on and charging and I try to turn it off while charging it would power off but immediately turn back on. I am on stock at&t with their latest official update.
I have not changed anything in the phone or installed any new apps. What would be like to cause this and could it be fixed?

So that's problem? I don't see there any problem... When phone is in off state & you plug it in charger, it will show your battery charging (aka Charge only). Again if you will turn off charging phone it will always boot to charge only mode... So that's normal.

No the phone never turned on before like to the android OS, it just charged. Now it turns completely on when the phone is off and it gets plugged into the charger.

Try reflash AT&T 125 final ICS via RSD lite. That issue was on Cmdefy recovery customs roms & it was solved by installing BMM. I think you'll need to root & install BMM (aka Boot Menu Manager) to check if phone in off state turn yellowish led when connecting to charger (This feature is on BMM 0.3.4).

Xiaomi MI4 does not turn, only gets red LED.

Hello everyone.

Does your pc detect anything when you plug usb cable ?

Yes, it detects, but then disconnects, can it be a problem in the battery?

Chances are you have received a refurbished device or defective battery.
Try and find another Mi4 user for trial of the battery or let's see you need to contact the vendor soon.

Charge via wall adapter. Leave it for some time.
PS: When your battery reaches 9-10%, it is advisable to charge it back to 100%.

I just got this issue 10min ago. Havn't depleted the battery on the phone for a very long time, my guess is that it hasn't calibrated the battery in a while or something like that. Will keep it in the fast charger during the night and then i'll reply here.
EDIT: Normally the red LED is constantly on when the battery is low and it's in the charger, now it's flashing which makes it look a bit more scary.
EDIT2: Works fine now after a night of charging

Charger could be not pushing enough voltage to charge battery. Try another one to see if it remedies the issue.

I do have the same problem with my Mi4. I wanted to start the update in the Updater app (to Android 6 version of Xiaomi.eu) and suddenly it turned off (at 100% battery). When I connect my phone with my computer it is recognized and all the partitions are mounted. And with all I mean all. There are about 7 partitions mounted (Linux and Windows) and they keep being mounted until I disconnect the phone. I let my Mi4 on the wall charger for 24 hours (2A Samsung one which charges all my other devices without any problems) but I still have the blinking red light after connecting it to the charger. Any other things I can do to get it running again?
EDIT: I can't see the phone in fastboot or adb and when I keep the power button pressed for about 10s it seems to disconnect and instantly reconnect the phone.

I solved this problem on my own. Even though the phone doesn't show up on the fastboot devices list you can use the Mi Flash Tool to flash the fastboot update (http://xiaomiadvices.com/miui-7-flash-fastboot-rom-on-xiaomi-phones-using-mi-flash-tool/). The drivers installed with the Mi Flash Tool for the Windows 10 Mobile Release (http://en.miui.com/thread-189369-1-1.html) recognize all the partitions as one device and show it with a cryptical name in the flash list.

Hi ! I fully charged the phone and after it shuted down. It doesn't starts. PC doesn't see it. When I'm plugin the wire just half way into the phone the red light stays on for a few seconds and than nothing at all. Can anyone help me?

Push power+vol up for quite enough lets say 20 sec

same problem here i kept charging for whole night but phone not getting on.. only red LED comes when kept for charging and not detected in PC also. Can any 1 help on this

I had the same problem ( strangely,it occured after a whole night charging, f... knows what happened)
Tried to change charger. No luck. The phone won't even boot by pushing Vol down+ Power
Solution: I simply connected the phone to a portable external charger, and tadaaaa !!! it was brought back to life !
Hope this helps

My phone is completely dead.

My phone is completely dead.
my mobile wont turn on even after charging for more than 12hrs.Only white led comes without blinking and goes after 5-10 min. Anyone hav solution?? it has 60% charge and when i tried to charge it with car charger it wont turn on afterwords..

If you can get into bootloader then flash the firmware. Probably the firmware is damaged.

Still under warranty...?

No its not at all booting only led .i cant able to get into bootloader

nope

You could test it with another battery maybe?, i had one with a similar problem, and by far i noticed the problem was the batt

i will try with another battery and report to you.

Did you downgrade your ROM and then updated via OTA? If that is the case, you have probably hard bricked your phone.

nope battery was at 60% and i tried to charge with car charger since then it is not turning on.

Battery completely dead or other hardware issue? [semi-resolved]

Hi All, my wifes s6 (using xtrestolite rom) has stopped taking a charge. Im trying to figure out what the issue is. Unfortunately im travelling for the next month so have limited trouble shooting options.
Background
- wife has been complaining that her phone battery dies quickly. I kind of dimissed her assuming it was in her head. she said it loses 10percent in standby mode in 1hr roughly. Shes been complaining about this for a week.
- yesterday at the airport her battery was at 12% and when we plugged it in to charge it wouldnt take a charge. Bolt icon did not come up and still said "connect charger" on the screen. Normally when connected the red Led comes on, but now it doesnt.
-our normal chsrging method is using and aukey 3port charger as fast charging mode.
Troubleshooting/diagnosis
- i have an s6 as well so i tested all the cables and chargers on my phone and it works. We even had the official samsung charger and cable but same issue.
- after the phone was completely dead, if you plug in the charging cable the charging bolt icon comes on for a few sec, the top left says "kernel is on seandroid enforcing" for a sec and then everything goes blank. Red charging led doesnt come on. So it seems like it detects the cable but wont charge enough to boot up.
- i was able to boot into twrp recovery but where its supposed to have a battery level its completely blank. Originally i was able to do this without any canles but then it wouldnt. My guess is that i orginally had a bit of juice and then it was completely dead.
-after leaving it plugged in for a sec, im able to turn it on where it boots and i can see it says 0% battery. It stays on for 5sec before turning off itself.
- i also tried plugging it into laptop, but laptop does not detect it. The phone does detect the power though and does the same as above but this time bolt charging icon stayes on for 1-2min before going off and seeing the "kernel is on seandroid icon". Once the seanadroid goes away nothing seems to happen. After doing this i was able to turn it on and it showed 1%. I thought this was promising but after trying this a few times ive never been able to get to 1percent again.
- with the brief charge thst i guess its getting, i was able to go i to twrp recovery and do a factory reset. This was with cable plugged in the whole time. Without cable in i dont think it would complete the action.
That about summarizes whats happened.
Ive concluded the following:
- charger and cables are ok and not the issue
- it is not the charging port since the phone does seem to be getting some juice bacause charging icon comes on for 2sec whenever cable is plugged in.
- its not a software/app issue since it wont charge even in recovery mode. Also factory reset was done and no luck.
My best guess is that the battery can only hold a 0-1% charge which is enough to register it being plugged in but not enough to do anything else. But if everything else is ok shouldnt it work when if the cable is just left in. This makes me think theres something else going on.
Any suggestions or theories would be much appreciated trying to decide if i should pay to get battery replaced.
Sorry for the long post. Figured it is best to give all info.
Thanks in advance!
Update June 3:
Hey everyone, just a correction on the above. It looks like it is able to charge in recovery (slowly). I realized that although there is no battery level during recovery, no charging led, and not booting up after being charged for a bit, maybe its just going slowly.
So i went into recovery and left it overnight on the non-fast charging and woke up after 8hrs and it was at 78percent!!!
Im not sure why it didnt go to 100% in 8hrs.
The phone still doesnt charge regularly when plugged in, so still need to fix that.
Do you guys think its a rom issue (only factory reset done before) ? I will see if i can get a rom for flashing.
Update 2:
Reflashed xtrestolite rom but still no luck. It wont charge.

Seems like a dead battery.

Bump.
Went to the phone store and they said its probably not the battery but the ic chip for charging? This will cost 150, but doesnt include the screen if they break it...
Does this make sense since i can charge in recovery.
Thanks. Any direction or input is much appreciated.

Go on the local store and change your battery (if isn't in warranty)

Hi all, just wanted to update the post that the issue is semi-fixed.
I brought it into a repair shop who offered to diagnose the problem for free before paying to replace the battery.
He told me there was nothing wrong with it and not sure what my issue was. Plugs in the charger and lo and behold it was charging. He said he didnt do anytning to it except blow some compressed air on the port.
Im guessing the comporessed air cleaned out a short? So now it charges properly.
The issue remaining is that the pc doesnt detect the phone. It shows as charging on the phone but no conmection. Tried to install the latest samung driver (1.5.4xxx?) but no luck. On occation sometimes it says "usb port has malfunctioned" but other times nothing.
My s6 does actually connect, so definitely my wife's s6 itself and not comp. Im tempted to buy some comlressed air and give it ankther blow, but dont want to risk messing it up again. im pretty happy that it at least charges up.
Hope this helps others that might have similar issue.

Mate 8 won't start charging until reboot

Hello,
I've started to run into an issue with my Huawei Mate 8: sometimes it will stop charging before 100% (most of times it happened during calls) and wont start again until rebooted. Unplugging and plugging the cord back doesn't seem to help. The only way to make the phone to charge again is to reboot it. It all started a week after the battery was replaced at service (old one got damaged over time and was holding power for like 1 hour of use). I already tested with a different charger to eliminate the possibility that the charger has issues. I've been wondering if someone else ran into this issue and was able to fix it, and if it might be a hardware issue (has to do with the battery change)?
Thanks

i have the same problem here but for me i started facing this problem after i replaced my battery and also updated my Android to Nougat 7.0 back to back. for me even rebooting don't help fix the issue. whenever i try to charge my phone with wall charger it doesn't respond but when i use USB cable to charge it via my laptop it's charging but my phone have to be shut down to keep charging . i really hope someone can help us.
Thanks

i have been facing the exact same problem. i rolled back to Marshmallow and it is charging fine but when i upgraded to Nougut it will not charge again. so it is the problem with update. i replaced my battery too by the way.
it is really annoying since i want to keep Nougut. did not like Marshmallow.

Same problem here, started after changing the battery

I faced the same problem, what helped for me:
Discharge the phone ~5%. Turn off the phone. Recharge to 100%. Boot the phone.
Use the phone till ~5% and redo the procedure once.
After that phone also allows me to recharge it while it was still turned on (without reboot).
