[BUG]&[FIX] Battery stuck at 100%

*** Mod Update ***
Confirmed "FIX" : you just need to reboot the phone
To Reproduce the BUG: it's only happens when you charge it up to 100% with AC plug, and leave it there for long
However if you charge it via computer USB, then it doesn't get stuck at 100%
--- Original Content Below ---
I contacted T-Mobile yesterday in regards to my battery continuing to be stuck at 100% after fully charging. This had been happening for the past 4 days for me. They really didn't have a lot of answers, however, the one thing they suggested is for me to reboot into recovery, in my case, clockwork recovery as I am rooted, and wipe cache. I took it a few steps further and did the following:
- wiped cache in recovery
- wiped delvik-cache
- wiped battery stats
- rebooted and charged phone to 100% at which point I ran battery calibration
Immediately the battery responded and started updating with the correct percentages. I have since charged the battery two additional times with each time the battery responding appropriately.
I am not sure which step fixed it or if it will indeed fix your similar issue. However, I wanted to pass along these steps as it may help someone out there.

i exchanged mine for that reason and it did it once and hasnt done it again. id sure like to know the reason for it

If you charge with duferent charger then it gets stock on 100%

I always used the stock charger and the issue was there.

my wife is on her 2nd phone with this issue. we have a day left before the two week grace period is up. i'll try the fix you suggested today and hopefully it works! i have a bad feeling i'll get some ugly looks from the tmob people if i come in there again!

On my 2nd phone, exchanged do to random shutdowns. Anyway, it happened on this phone as well. I did the steps listed and it hasn't returned.

It's only happened to me once, but a reboot fixed it.
Granted, it shouldn't be happening, but is this really happening frequently enough to be considered a 'problem'? I got my galaxy on launch day and it's only happened that one time, the second day I had it.

Couple of things i think may have resolved it for me, but i still am not sure what exactly made it work.
- Charged the phone to 100%
- Did battery caliberation which deleted battery.stats
Still was stuck at 100%
By afternoon i connected the phone to computer using USB, it beeped that the phone is fully charged, i unplugged it by mistake and plugged it back in and it displayed the correct battery.
- Charged that night with the original charger (Was using a different one before)
Since then it is working fine for me.

I had somewhat the same problem, only on my Sony Ericsson Xperia Mini. The battery got stuck at 100%, no matter what i did (clearing batterystats.bin, charging with original charger, charging via USB, bumping it...).
The battery also stopped charging at 3,7V instead of charging over 4V.
The last thing that worked for me was taking out the battery for 5 minutes and then reinserting it. 3 days of effortless troubleshooting, and a simple battery pull saved me from sending the phone in to my carrier.

whenever i get a 100% stuck i just boot into CWR and select the option to wipe battery history
then it all goes back to normal

i just shut down the phone via the power button on the right side and turn it back on. works every time. a shame though.. shouldn't have to do this.. i hope samsung/tmobile fixes this.

Yeah I just reboot it every morning after unplugging the phone.

Got a replacement phone and it happened again once. Booted in Clockwork Recovery and followed the steps I posted in the OP and it hasn't happened again.

Happened to me a few times....a reboot fixed it for me....not a big deal for me...i just reboot when it happens...

I also have this problem. I am currently rooted, but using the stock ROM/Kernel. Although I did have this problem before I rooted too. I was wondering if any of the ROMs or Kernels are known to solve this problem. Then we would know for sure that this is a software problem the tmo/sammy can fix.

It's from the charger. Use the charger the phone came with. im using the original galaxy s charger and no problem whrn i charge with other charger overnight it gets stock .

For me the charger I use does not make a difference. In fact, the real symptom here is that the phone is stuck at 100% when it is off the charger. Sometimes when disconnecting the phone from the charger after a "successful" charge, the phone will stay at 100%. If this happens, then even connecting the phone to a charger (perhaps after a couple of hours so you would know that the phone is actually at some percentage less than 100%) will not cause the phone to realize that it is in fact NOT at 100%. What's more, since the phone thinks it is at 100% it will not charge itself. The only cure I have seen is that when I notice that the phone is still at 100% after it has been disconnected from the charger for long enough that I know it should be less than 100% is to reboot the phone. Once I do that then the phone is good to go.

Maybe this can help... I've never had the problem until I charged the phone while it was powered off. Due to the nature of my job, I leave my phone on 24/7 and never had the issue until reading about battery management and doing a charge while powered down. After turning the phone back on, I had this issue until a reboot which fixed it.

If it's anything like the problem we are experiencing, then it means you will have to reboot every time you complete a charge, since it gets stuck at 100%.
This is getting to be really annoying ... having to reboot every morning after a charge. I really wish Samsung would release a patch or something.

Mines only done that once, it got stuck at 100 aftervi unplugged it, reboot fixed it, but it hasnt happened to me since

[Q] [Help] usb charging and mounting problem

Hi guys, any help would be appreciated. Basically in order to charge my phone i have to plug the cable in and reboot my phone so it knows its charging even when this is done it doesnt charge correctly as it usually jumps 50-60% after the reboot. Then using throughout the day it will drop suddenly then tell me its charging even though its not plugged in and the battery % actually goes up. This was fairly amusing but now im worried. The second problem is now my computer no longer regonises my phone saying its malfuctioned and my phone doesnt know its plugged in untill after a reboot where it will charge but again not register its plugged into a computer.
To me its seems like a software fault however after a data wipe/factory reset and battery stats wipe and reflash the problem persits. I am on AOKP M4 with latest franco nightly.
Ive put it down to three things that i did that night:
1) accidently plugged it into my tablet charger
2)used the fast charge on franco's app i have disabled this with no effect
3)Had a system UI crash after my torch went funny
Edit: Tablet charger output is 5.3v, 2.0A for my touchpad

Lol, this seems to be quite a big problem.. I did a quick search on this forum over the last two months, and found these threads with the same problem:

The problem is a faulty USB port, and Samsung/Google really should take action on this!
I took action myself and changed it myself..

Wow ok thanks, I did do a little search nothing seemed exactly like my problem but yes a few of them threads do so thanks for putting all that leg work in hah. Ah if i opened it up don't think i could put it back together. Thanks for the advice.

My Samsung Galaxy Nexus won't turn on

First of all I read all the possible posts here in the XDA forum about this problem but no one was able to help me :s
I was listening music with my cellphone than it crashed and turned of from nohting. My first thought was "Damm, it crashed!" and I removed the battery and after a couple minutes I put it back and than the cellphone never turned on again. No battery status is showing up, no leds, odin and flash mode doens't work either. I don't no what to do :s
I tried this:
◘ Unplug from USB, remove battery 5 min, put it back
◘ Odin and Flash mode
◘ Turn it on without battery on pc
◘ Turn it on while recharging
My GNexus model is a I9250 GSM.

Could you add some more details? How long the phone's been in operation, refurbished?, rooted?, your current ROM, kernel, radios, advanced kernel settings such as voltage changes, any tweaks, battery type, temperature.
This exactly happened to me on my DroidX. I spent 2 weeks trying everything to revive it including taking the phone apart before adding it to the pile and getting my current GNexus Toro.. so I know how much this sucks. I'm not an expert on phones bricking but I know that connections can go bad or come loose, especially if the phone has been dropped or other impact, components start to lose their integrity over time and voltage shorts 'burn out' op-amps. You mentioned listening to music, so I'm wandering about the IVA components burning out, which usually has voltage too high especially on boot... Hope you can get it working.

Well first of all I thank you for your concern and my phone is on again, thanks to my uncle. The phone is '4 months old', I rooted last month, bootloader unlocked and I was using samsung stock rom (4.2.1 JB). Yeah, that really suck monkey b*lls. If you got the same problem as me (I really hope not) that's what you should do: First remove the battery, plug the charger and than put the battery back. In my case, It kind "shorted" the battery and my phone is back on. I was reading posts and posts and discovered that GNexus has this problem and a lot. Dunno when it can happen again but I really don't want a paperweight. Once again, thank you!

Glad you got your Nexus back up and runnning. Thanks for posting back with details after you figured out the problem and got your phone working, +1 right there. There's always a good chance this will help out someone later on. :good:

Confirmation: balums worked for me
balums uncle's solution worked for me: specifically, (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button.
Thanks balums!
Does anybody have technical (design/EE) insight into what would cause this?
This was starting from a device that appeared totally dead.
The battery was *fully charged* (and showed up that way immediately when the device finally booted).
I had done the obvious things of removing/inserting the battery, cleaning contacts, checking the USB power connection.
Was about to pull it apart when I saw balums post, saving me huge time.
Device is about 16 months old. Stock OS and settings. First time this has happened.
Search terms:
CDMA (Verizon) Samsung Galaxy Nexus -- SCH-i515.
Phone won't boot. Device won't turn on. Won't start. Dead. No worky.
Thanks,
Seth

Awesome! You trick worked, balums!
Interestingly I also have the standard stock version of OS and Hardware which I bought 14 Months ago (nearly to the day). I was surfing over WiFi yesterday evening and when I turned the phone off I noticed the screen getting grey for a moment, not black. And this morning the Nexus just didn't turn on.
Anyway, thanks for the solution, have a nice day!

That is very odd because my i515 also did the exact same thing and I have owned it for 15 months. I can't wait to get home and try this trick. More to come.

Thanks!

Galaxy nexus wont turn on or charge.
I tried (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button but my galaxy nexus still dont turn on. i have 4.2.2 stock rooted. i was downloading something and my screen become weird in colors and i cent use the phone. i turn it of and now wont turn on again or charge.
after unlocking and rooting i installed this touch recovery from google play. [ROOT]Recovery Tools

Excellent! balums' suggestion helped me. I thought I had tried this before but apparently didn't quite get this in the right sequence.
The only remaining issue I have now is that when it does turn on, I've got the thunderbolt on the battery indicator, the phone says it's charging at the lock screen, but when I go to Battery under Settings it says that the battery is discharging. This effectively has my phone in a state where I can't unplug it (battery is too low but it also doesn't appear to actually "charge"). I tried replacing the Micro USB charge port PCB board and came up with the same results. To me, this seems like a problem and may indicate a motherboard or battery connection issue. I used the "Battery Monitor Widget" and it indicated that it was getting AC power. Any thoughts?

Thanks to XDA and Balum's suggestion! I thought my phone just died! It was on 70somethign % battery last I looked, connected by USB to the PC and I don't know if I turned it off and walked away for a while or if it turned off by itself, but it would not turn on no matter what I did after I got back to my desk. It is on Android 4.3 takju stock not rooted.
Thank you all again for the instructions on how to revive the GNex!

Samsung Galaxy Nexus won't power up
I got a Samsung Galaxy Nexus. I got it from my cousin and therefore don't have any information about the rooting status as well as the ROM but i guess it was running stock. The phone won't turn ON, it is not detected in the computer. No LED or any other indication. I tried the above method which worked for many people but it failed. What is special about the phone is that the upper part of the screen is heating up more as compared to the rest of the phone. Can somebody help me fix this? Is this a hardware issue?

I have the EXACT same problem as you do. I have no idea where to start to try to fix it. I took a picture, then lines went squiggly across the screen, then it flickered, and died. I cannot power it on at all. I tried Uncle's tricks. No luck.
Anyone have some ideas on what to try? Thanks.

Also having the same problem. My Nexus has been rebooting randomly for the past week or so, and finally, this morning, it refuses to turn on at all.
It's a Verizon Galaxy Nexus running stock, but it's been rooted. I'm using the extended battery. The trick that was posted earlier in this thread doesn't seem to work for me. I've tried multiple USB cables and power sources.
I'm going to try the standard battery when I get home, but I'm not expecting positive results.

Work-around
About two months ago whenever I turned my Gnex off, it became totally unresponsive to all attempts to start again. After a lot of trial and error, I discovered that if I pulled the battery for 30-60 minutes and reinstalled, it would power on normally. I have completely wiped and rooted the phone and the problem persisted.
Today I thought about it some and realized there may be some residual charge in the phone, and my waiting period is to allow the charge to drain. To test this theory, I powered the phone down and then tried to restart - nada. Pulled and reset the battery - nada. Pulled the battery, shorted out all four pins that would make contact with the battery, reinstalled battery, and it powered right up. I have not been able to successfully repeat a fast restart when shorting out all four pins. Pulling the battery and waiting 30-60 mins still works.
Incidently about the same time, my screen has stopped auto rotating (and yes it is set to do so).

galaxy nexus reboot
my galaxy nexus is about 1 year old now and this is the first time that i've encountered a problem with it. It suddenly restarted, and will take about 5-7minutes before it opens, it will be open up to the "X" logo and when it reaches the normal screen it will restart again. I don't know whats wrong with it. please help/

You saved my Galaxy Nexus

Similar problem + water
Ok, so I have a similar situation I believe. My phone took a swim. I left it off and riced it. Later on after I believed it to be dry enough, i turned it on. (wow it freaking worked) After a few seconds of using the device checking screen the phone snapped off and went into a reboot. I waited until it came back and i shut it down and thought I'd let it go over night. I plugged it in and let it charge (charge icon was displaying). Everything looked good.
Fast forward. Morning time. I go to turn the phone on. Nothing.
This time the phone won't boot. Instead all i see is the white battery icon show up indicating the battery is 100%. When i plug it in to the charger i get the battery with the charging bolt, then it shows the normal battery indicator light. After that, I get nothing.
I tried the method I saw above. remove power, remove battery, apply usb power, insert battery, press power. Sadly it didn't work.
Anyone have any other ideas as to what might be going on?

[Q] Phone stopped charging after a a few odd beeps

A few hours ago my phone started emitting beeps as if some notification was turned on (I have all such off). I have not paid much attention, as the beeps eventually stopped (!!), except for when noticing, a while later, that the phone - albeit plugged in and with the battery indicator showing "charging" - the percentage was decreasing. I watched it for a while, and the batter was discharging while plugged in. Did the followings:
- replaced the battery with a new/charged one (my spare) - same behavior
- replaced the cable with the original samsung - still the same problem
- tried wall outlet charge, laptop charge (via USB), etc - same problem
The questions for those having experienced such:
- would the beeps be indicative of a problem, or just coincidental???
- the phone is definitely the culprit here - the question is if there is something that could be done for some sort of cleanup of the port, or improving the connection (seem to recall some such from a site - maybe this, maybe another forum - could not find the article by searching), or further tests I could carry out, before I take the phone into the repair shop (which I am not sure if there is such in my area)
TIA,
Stefan

can your phone charge with the phone off? Turn off the phone and then plug it in, do you see a big battery icon charging? Also is your phone rooted?

Upon turning the phone off and first plugging it in, it depicts a grey battery with a non-spinning wheel in the center. After approx. 10sec the screens starts showing a semi-filled with green battery, with a scrolling bar of dots underneath it (active this time, unlike the wheel described before).
I am sure that everyone knows what I am talking about, having seen it many times before, even if my description is not that good. The issue is that I have never paid attention to this part - mostly because I almost never had the phone plugged into power and not immediately turned on.
Observation after doing the above: after having left the phone off for almost an hour, the battery charge decreased (84% -> 80%) while the phone was plugged in.
NOTE: When the charge was 100%, by using a battery I charged with an external samsung charger, I also re-calibrated the battery using the app (phone is rooted, but always using the stock ROM). Just FYI - if that matters.
Thanks for any [ongoing] assistance.

ok if your phone was off and plugged in, and was still losing charge then I'm not sure what to do, sorry, hopefully someone else who has experienced and solved this can help you out.
my issue was similar to you where i couldn't charge my phone while it was on, i could only do it while it was off...it was a software issue, so i flashed the stock ROM, started from scratch and everything was fine from then on.
if you havent already, make a back up of all your important data (msgs, apps, etc.) download a stock rom (http://forum.xda-developers.com/showthread.php?t=2276645) and flash it, maybe that might solve the issue

The beeps may have been the phone detecting the charger on then off multiple times. Check the charge port on the phone for any breaks or debris.
Otherwise I dont know what to tell you aside from try another cable and charger. Sorry.

Damn ! I had this error too but it would charge but so SLOW! It was on a ROM/KERNEL that i've flashed , I cant remember wich one. Try charge your battery in Recovery ( this was my solution )

Charging Problems Please Help Have Had This Problem for Months and Still Do!!!

I have had this problem for about 2 months now, and it seems like everything I do, never fixes the problem. When I was rooted, I was having fun tweaking, flashing roms, and mods, but then one day my battery percentage was low so I plug my phone in the charger with the stock charger and cable that came with my GS3. I wait, 5 minutes goes by and I check my GS3 again, and it has the same exact battery percentage it had when I was going to plug it in to charge. Never even increased one single bit. So I thought to myself, that's strange. I wait another 5 minutes, and it only goes up by 1 percent. I was thinking to myself what the *beep*! Now I left it that night to charge, and I wake up... HOORAY! 100% fully charged! I take it out of the charger and BOOM! it drains all the way down, to a low percentage, which I'm pretty sure was the same percentage I had when I went to charge it last night. Now I was pissed man, phew, I got so mad! I read all over XDA and Android forums, and it seems like I'm not the only person who has this problem. There was one thread with like 10 pages and counting. There were answers like, "just wipe battery stats", I wiped battery stats, the problem still persists. It still takes a very long time to charge and, once I immediately take it out of my charger it drains, to a very low percentage. So then people were saying "it's the cable, just use a different cable" I use a cable from a Pantech charger and I wait. It charged my GS3 just like the way it is supposed too. I'm thinking to myself, great it's back to normal charging state! Then another day I plug it in the Pantech charger and my GS3 doesn't even recognize, that it is charging, no lightning symbol on the battery pic thing on the status bar. I wait and there has been no increase, but actually a decrease of battery. Again I was like what the *beep*! So I use various different chargers and my GS3 doesn't even recognize any of them that they are charging, EXCEPT for the stock Samsung charger that came with the GS3 which takes a very long time to charge and once it's fully charged and I take it out, it immediately drains to a low percentage. So I switched batteries with a friend of mine who had a high percentage, and I booted into CWM, and I wiped data/factory reset I wiped dalvik cache, and cache partition, and I reflashed my ROM. No fix. Same Problem. So I try many different ROMS, and every ROM I try. No fix. Same Problem. Even the very stable ones which supposedly have not many problems. I thought unrooting and going back to stock firmware would work. That's exactly what I did and... No fix. Same Problem. I downgraded to ICS and... No Fix. Same Problem. I have tried everything that people on XDA and other forums have said would fix the problem, and the problem is still there and it seems like it's not going anywhere.
SORRY FOR THIS LONG THREAD.
PLEASE PRIVATE MESSAGE ME ANYTHING THAT WOULD FIX THE PROBLEMS OR ANSWER IN THIS THREAD.
ANY HELP IS GREATLY APPRECIATED!
