HELP!!!! Fixing battery charging problem - ONE Q&A, Help & Troubleshooting

Hello,
I went out last Friday and came home late. My phone is out of battery and dead. I plugged it in and woke up the next day with a dead phone. Apparently, there is a bug with the OPO. If the battery is too low, it won't even charge after you plug it in for charging. I have tried all tricks and even contact the OPO Tech Support Team. This thread describes how horrible they are:
http://forum.xda-developers.com/oneplus-one/general/tech-support-onepluse-one-horrible-t3084022
I am at my wit's end. I have tried all the the tricks. This is a thread that I found that seems to have the same problem as I have.
http://forum.xda-developers.com/oneplus-one/help/oneplusone-phone-dead-t3079256
The only choice I have left is to open the phone, disconnect the battery connection and reconnection it again. Hoping it will recharge. However, there is a warranty sticker and I don't want OPO to deny my warranty. I am not new to Android and I have fixed phones before. I also think of buying a new OPO battery and switch it with the factory one. Since the new battery will be charged, I think that will work in fixing it. But, doing that is much more complicate and it requires me to remove more components. If you have a good working solution for my problem, please help.
NOTE: please don't ask me to check my charger or use a different one. I check it 1000 times already. The original charger works, the cable works. I use different chargers and cables. Same result.
Thank you for your help.

Have you rooted and unlocked? I had the same problem when I got mine at first. It would show charging but never fully charge. 73% was all it would do. So after rooting and flashing a custom kernel the problem went away. Now I can go back to stock and the problem has never comeback. Maybe just a small software glitch or something. I'm just happy it's gone!

The phone is unlocked and rooted. The issue is not fully charged or not. The issue here is the phone does not charge after the battery die. The phone is dead because I let the battery run to 0. When I plug it to recharge, the low battery screen does not even come up. The phone is dead and refuse to recharge. There is no issue with the charger or the charging cable. I have checked it several time already. I am very frustrated with OPO Tech Support right now.

I see. Only other thing I can think of is try holding the power button for 60 seconds while it's plugged in. That does suck man.

I had similar issue, my conclusion is the bootloader charging function is broken.
Basically I would start the charging, it would charge for about 10 seconds or so, and then stop. I thought my battery was dead.
I couldnt boot the os as wasnt enough charge.
So eventually I just kept repeating the process, 10 seconds charge at a time, and eventually had enough juice to boot android and after that point it charged to full ok.
Never had this issue on any of my samsung phones.
Also to point out when it went dead it was plugged into my pc usb at the time with twrp loaded.

[Q] Damaged Captivate - Any help would be appreciated.

I've searched the forums and have not seen anything quite like my problem, so if I missed an important thread, I'm sorry.
Over the weekend, I plugged my Captivate (using a stock battery) into the official Samsung charger and overnight my roommate semi-dislodged the charger. When I woke up and grabbed my phone it only registered a few hours of charging yet still had almost full battery. Upon rebooting the phone, I was sent into a bootloop. Not at the ROM, not at the Kernel, not even at the bootloader. It goes so far as to show the white loading ring at the center of the screen which never moves. At one point, a thin pink line appears halfway through the screen as it shuts down and reboots, never making it any farther. If I plug the phone in, it will boot normally though it does not accurately report battery levels or charging.
Other oddities: after 5 minutes of a phone call, the phone hard crashes. Not FC's, but just goes black. Upon a reboot, I get stuck into the same boot loop. If I plug the phone into the wall charger without a battery, it will go into the turned-off charging animation and show a 100% charged battery. Furthermore, my other roommate has a brand new i9000 so I tried that battery (again, stock Samsung) and it continues in the same bootloop. I have tried flashing other ROMS and going back to stock, but that does not seem to help.
Other info: I was running OneCosmic's ICS 3.1 with no overclock and light undervolting at the time. It was perfectly stable for the few days until the charger dislodged. I am also out of warranty and am not eligible for a hardware upgrade so repairing my Captivate would be ideal. I also have a usb jig if that is of any use to this scenario.
Has anyone experienced anything remotely like this? If not, what debugging steps should I attempt?
What I would suggest is using one of the ODIN one clicks and flash back to stock
Sent from my SGH-I897 using xda premium
I've flashed back to Rogers 2.2 stock. Doesn't help. It actually made it harder for me to get the phone started though I have yet to make a phone call from it.
Have you had the phone for less than a year? if so call at&t(or rogers) and they'll replace it for you.
then try factory reset
then try using odin or rom manager to flash back to stock
When all else fails, flash to cm7. that will completely wipe everything and start from scratch.
if that STILL dost work.... than you can be sure that its a hardware problem :/ theres nothing you can do except replace and sell for for parts.. sorry
You may want to try clearing the battery stats. Something in there may be telling the phone that the battery is completely dead and it shuts the phone down in the middle of the boot. Just a guess, though.
It sounds to me like the phone might have gotten confused aobut how much battery life it actually has. You might also try getting it loaded up and then letting it drain the battery completely down. Reset the stats and then fully recharge the phone.

I have exactly the same problem, I did the reset of the battery stats and still not working.
Did you solve the problem?
thanks

Thanks to everyone for their suggestions, however, no amount of battery calibration could get it to work. Furthermore, a bad flash has made the situation even worse. Now Im bootlooping even when plugged in and when unplugged my jig is of no help. I have declared my Captivate dead.
Best of luck toominds, if you get it to work, let me know. I'd love to have a spare phone sitting around.

[Q] Quasi-Pseudo-Semi Bricked?

I bought an Atrix 2 a couple of weeks ago. I rooted it and installed cm10, but did not flash any roms (I preferred to have HDMI). Last weekend, my phone ran out of batteries. Plugging it in caused the white LED to flash, but the phone did not wake up after many hours of charging. Since I was away, at a place where I didn't need a phone, I put it aside for a few days.
Upon returning, I plugged my phone into the wall again. A few hours later it woke up, booted, and began to work normally. I charged it fully and used it for a couple of days. A few hours ago it ran out of batteries again, and plugging it in gives the white LED and nothing else. Sometimes when I plug it in the LED will turn off for a moment and the phone will blink, but the screen does not turn on.
Does anyone have any advice? When the phone was on earlier today it worked and charged normally..

First, before you do anything else, research exactly what it is that you are doing. You say you installed cm10 but didn't flash a ROM. It might have been helpful for you to know that cm10 is a ROM. It might have also been helpful to know that HDMI does not work on cm10. As for your battery issue, that has happened to me almost every time my battery has been fully discharged, so I take care to be sure that it doesn't happen. If possible, try charging the battery with an external charger. Then as, I stated in the beginning, research what you are doing BEFORE doing anything else. The best place to start is here:

Sorry, meant clockwork mod, not cyanogen. I haven't flashed any ROMs on this phone yet.
Do you think the battery issue arose as a result of rooting/installing clockwork mod?
No no..Many phones these days fail to charge when drained because they use software to detect the charger and then allow current to flow.. This is unlike the older nokia phones or current HTC phones.. what you can do is as suggested above.. use a 9V battery or something that ought to do it.

[Q] Nexus 5 charging only when it is turned off

Hey there!
My Nexus 5, after updating it to 4.4.3, is having a issue: the device is charging only when it is turned off. When I turn the phone on, while charging, it will remain charging. But if I connect the charger, when the phone is already turned on, it will not charge.
I have tested 2 different cables, same issue.
Is anyone else having the same problem? How to fix it?
Any help would be appreciated. Thanks!
Just for clarification: I'm using Kit Kat 4.4.3, rooted, Xposed.
what are you charging from? ac or pc?
AC!

Another question, are you using the stock wall wart? Some aftermarket chargers don't put out enough amperage. Another possibility is that you've got some rogue processes keeping your phone awake so it's using battery as quickly (or quicker) than it can take in a charge.
I'm using the AC charger that came with my Nexus 5.
Updated to 4.4.4. Problem not solved.
I think it might be a hardware issue. I have the same problem with my pebble. I have tried multiple cables/chargers and it only charges when it's off. When it's on I get the charging notification but it doesn't actually charge
Nothing. The devide is still charging only when it is turned off.
Having the same issue since update 2 weeks ago. Already wiped phone and problem still exist. Start to think it's hardware but tried 2 different charger same issue.
So guys I am almost the same problem since this morning. I went on a 3 day trip to the Netherlands on Friday and charged my phone in the car for the last time on friday. I died on me this morning. While I was on the way back today and my N5 was in it's last percents of battery I noticed it wouldnt charge anymore. I thought fastcharging might have killed my car radio. Now back home I tried to charge it. For some reason the charging while off screen reapeared as soon as it turned off. Whenn I turned it on again it stopped charging. Tried rebooting multiple times. My phone now only charges while being in Fastboot or Recovery mode. Anybody having any ideas what might have caused this an how to fix this? Cleaning the charger didn't help me.

Hi. Also had this problem a few days now. Alot of headscraching is done
N5 won`t charge when on. Tried my N10 charger, but still the same. With my wireless charger it register the phone when off, but cannot charge it at all. I've also done a factory reset, and even changed the battery. Still no solution. Wondering if the charging port is damaged somehow. It doesn't cost much so maybe I`ll order a new and replace it to. I remember draining the battery more than usual right before this issue acurred. I was hiking, and din`t bring my portable charger. Also it could be some kind of water damage. Had the phone in my pocket all the time, it was not raining, but I got pretty sweaty:-9 Never had any issue with my stock Nexus 5 up till now. Don`t think this i a common problem, when this is the only place I've found others with this issue I`ll order the charging port, keep on searching on forums, and take it from there.
Good luck
I'm having the same problem on my Nexus 5 now as well. When on, it won't charge via micro-usb (via original charger or USB-to-PC), nor will it charge wirelessly. When turned completely off, it charges, but at GREATLY GREATLY reduced speed. It seems to be stuck in a loop as it it's just been plugged in. It cycles continuously through the lightning-bolt battery image, followed by the charge percentage graphic. The screen blinks, then it starts again. I suspect that it only charges for a moment or two before each reset. For example, it only charged about 20% over the span of six hours last night.
I've tried four chargers and four USB cables, and of course both wireless and wired charging. It's something with the hardware I suspect.
Anyone have any suggestions? It looks the the factory wipe upthread didn't help...
Charging spare part
I am having same problem too. I'm guessing it's because of water damage. Where did you find the charging part? I'm thinking of ordering one for myself to see if the problem is fixed!

Having the same problem now too. Won't Qi or USB charge from OEM charger and cable while powered on.
Appears to be charging fine while powered off.
Did anyone come up with a resolution?

LG G3 - Fried battery and/or charging port?

Let me lay down the story first:
It all started when I tried out multiROM for the LG G3. I was running cm12 perfectly fine, unlocked and everything. Amazing battery life. But MultiROM barely worked, even though I followed the instructions exactly, I had many errors trying to get anything to boot properly. I got help with it, but ended up getting rid of multirom via internal storage (where it was) and flashing a normal, non modified TWRP 2.8.4.0. This is where stuff starts getting weird.
After getting rid of multiROM and flashing cm12 again from backup, I noticed my phone wouldn't take a charge at all. It was booted up and running at about 30% battery. My PC wouldnt do anything when I plugged it into my computer, too. I thought it was just Cyan being weird, so I rebooted into twrp and tried plugging in. No buzz, still wouldn't take a charge. For some reason, turning the phone off and plugging in the charger while it was off actually turned it on. So the charging port has to be working, the phones just being weird... but then I decided to smell the charging port. Smells like pure burning electronics. I rebooted the phone with the cable plugged in, and it boots up and charges. This is odd, because i can no longer plug the cable in while the phone is on, i have to reboot it with the cable in now in order to get it to charge. I tried flashing back to stock ROM, and same exact issue happens. Not only that, but the battery no longer holds a charge for more than a day on one full charge. It lasts about 3-4 hours now.
Please, xdaers, help a brotha out. I'm really pissed about whatever the hell is happening to my G3. It still works fine, I just have to reboot it with the cable in in order to get it to charge at all and the battery life sucks on top of that.
Note: One time after all this happened, the phone died fully. Plugging the charger in, the battery logo was flashing on and off. I tried multiple cables and chargers with the same problem. I pulled out the battery with the cable still in, and the battery logo actually stayed on the screen and once I put the battery back in, it charged again. THIS IS MAJORLY CONFUSING and hard to explain so I will clarify my issue if you are confused with my post.
Also, the phone likes to get really hot and die fast by itself even without the charger plugged in now.
thanks guys

So you flashtooled back to stock? And still persists? If so you next option is to buy both a battery and a charging port and do some trouble shooting.

Don't know about the charging port, but as far as battery life I'm getting the same thing, except mine lasts about 2 hours, I've decided I'm selling the phone while its still worth a bit of money, probably getting a Note 2 or Xperia Z2, I've been very unhappy with this phone, also my battery cover is falling apart and cracking,

Well I've had none of your problems. Note 2 or z2 is a downgrade. Have fun with that... Sucks your experience hasn't been a good one. Cheers

I get 13+ hours with 4 to 5 hours screen on time and 1to 2 hours of talk time. So I don't think your battery issue is normal for this phone. You have either a defective battery or phone or an app that is misbehaving.
I'm having the exact same problem with LG G3.
Can only charge when rebooted. And even then the charge indicator does not show charging.
I have to go into setting->battery where it shows 'charging'
I have tried new battery and cleaning port.
Anyone figure this out...?
My battery drained very fast before too after backed up to stock, but after I upgraded to 5.0, my phone can lives up to next morning!

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.
