[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).

Phone acting weird and won't charge unless it is power off.

Hi everyone,
I have several problems with my AT&T 8X. First, the screen keeps on cycling through the brightness level non stop, so its constantly changing the brightness. I've tried to turn off the auto-brightness but that doesnt seem to help and this only happen after the phone booted up and I touch the screen so Im thinking it's a software issue. ANother one is that when the phone is one, the computer wont recognize the phone and it won't charge, both AC and PC charging. To charge the phone I would have to power it off and plug it in. It wouldn;t have been so bad if it wasnt for the fact that whenever the phone is power on again, there's a high chance that it will boot loop and I'll have to do a hard reset to fix it. All of these looks to be software problem to me. Hard reset doesnt seem to fix them though, does anyone has any idea?

Never faced any such problem till now Try visiting htc service centre Or try draining the battery completely and charge it completely before using Sometimes solves my screen related issues

I actually did drain the battery and charge it up again. I had to remove the screen though since it wont charge keep keep boot loop every 3 seconds. so I had to take out the screen and charge the battery separately by manually hook up the wires to it. And htc service center is no longer an option since it is no longer under warranty, which is why I opened it up in the first place lol.

You'd taken out the battery?? Thats a really hard work!! Battery is hidden inside right? and we'll have to remove everything just to reach the battery!! Did you do it on your own? I'd actually heard removing battery is very dangerous and we should be very careful since it's behind the screen and the connecting wires are too thin :silly:

If you take off the screen, there's a cable that connect the screen and the components to the battery, all you have to do is unclip the cable and hook the wire to the battery correctly (positive and negative side) and just plug it in to charge for 30 mins. Since the phone won't turn on, the battery left to be charged fully rather than keeping going into bootloop.

You don't actually have to remove the battery, just need to separate the screen from the back.

droid mini charging

did XDA search and read that a battery calibration app could help remedy this, but I'm not sure. I am up to try anything at this point. But i cant keep it on long enough to get on google play??!
what happens is with this droid mini, when connected to the charger it actually discharges. I havent been able to get enough charge in it to fully finish booting but when it does it acts weird as though it doesnt want to boot up. then it will just shut off or reboot soon after. of course the phone is unusable at this point and I dont know why I bother, but my daughter is turning 12 and wants it so I'm trying to get it working. Any help is appreciated, thanks

Try a different charger?
Try a different cord?

tried both of those, still the same.
what it's doing is sorta like a boot loop in a way but its plugged in the whole time.
ok: plugged into charger immediately boots up. stays on for a few seconds and then the
low battery warning and the phone says i am going to shut down now, and it does. still plugged and taking no charge, still says 0% while plugged in. boots up again and shuts itself
off due to low battery, boots up again and shuts itself off due to low battery, and again, and again, over and over and over and over, until i get tired of hearing it reboot over and over and i unplug. its a mystery to me why it doesnt take a charge. tried the factory charger, tried an HTC charger, tried a samsung charger, tried every charger in the house.
Maybe the battery at this point? or some other problem? you tell me

phone dead, or is it? PLEASE HELP

i have an xperia z3 that has been working fine for five moths now on lollipop , however today i noticed that the battery indicator changed from 17 percent to 50 percent to 7 percent every couple of minutes, i looked up online and somewhere it said to let it discharge completely then recharge
in all stupidity i used m phone till it suddenly blacked out, i was like step 1: check
step 2 however wasnt working as when i plugged the charger it put up the charging battery screen with the red light, then it blacked out again and it just keeps on turning it self on and off from black screen to battery screen
id like to let it survive for a while till i can afford a new battery or something, can i do that? or is it hopeless.
i will let it charge for the night, however i need the phone in 3 days and cant afford a new battery WHAT DO I DO???????? PLEASE HELP ME!!!!!!
if you do know the cause of the problem enlighten me , many thanks

Check your charger and charging cable. Might not be charging properly. And that may have damaged your battery and charging related circuitry on your main board.

update: this is one hell of an issue
it appears this is a very common issue among phones and xperia phones specifically ,NEVER let your phone discharge
i found that i can get to fastboot mode and flash mode , but thats it cant reboot normally
i changed cables and chargers and even switched to magnetic charger,charged other devices using my charger to make sure, forced shut down using power+volume up and using the killswitch
but its all in vain and the problem is just the same, many people who had this problem got it fixed by forcing shut down and changing chargers but i let it for hours and hours to charge
i also updated from lollipop 5.0 to 5.1 via flashtools since i got to flash mode, i erased user data and everything and it installed perfectly
but still when i disconnected and pressed power button it showed the low battery icon and it still wont charge
is there anyway to chrge it from fastboot or flashmode and boot it from there cuz they work

I have no idea on that. I'm still New to this phone but yes, never let your phone fully drain. It's the characteristics of lithium ion battery.

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.
