[Q] Battery stuck at 100% | 1 hour no charger still 100% | cannot charge battery now

---

The Problem
As the title mentioned in the title my Battery is stuck at 100%, I've left it for an hour without the charger and it's still stuck at 100%. I plug the charger back in and the phone thinks it's fully charged so it doesn't charge.

I've turned my phone off and am awaiting instructions on a fix because if my battery goes flat I won't be able to charge it and my phone will be useless.

When it happened
I don't know when it happened exactly but I was getting S-OFF using the JUOPUNUTBEAR method as I had a H-BOOT of 1.27.0000 which revolutionary.io couldn't S-OFF.

Once I got S-OFF I installed LeeDroid ROM and then I noticed my battery was stuck at 100%.

What I've tried
Using a different battery (I have OEM and Anker)
Changing ROM to Android Revolution HD

Extra Information
While changing Roms I installed 4EXT Touch Recovery which in Recovery mode it has it's own Battery Meter, they also said the battery was full (though I didn't unplug it for long)

I have the same 100% stuck problem with Android Revolution HD, I'm starting to get worried and yes I have waited an hour without the charger connected and still have this problem.

Does it do this with all Rom? Have you tried to calibrate, possiably app might allow you to change the configuration? I'm just guessing here, hopefully you will find a fix. I've never heard of this before, this is a new one. Perhaps someone with more knowledge can help! Sorry I couldn't be of more help.

Have you tried using it heavily for 30 minutes like playing a game or something?

I experienced this issue but its only with some roms. I left my phone on overnight not charging (8pm-11am) when I last use the phone and it still said 100%.

try wiping battery stats first

use battery monitor widget or battery calibration app or from recovery(4EXT ->wipe|format->wipe battery stats )

then if it still didnt fix the issue
try another ROM or reflash the same rom...but before doing that ...
i want you to wipe everything using inbuilt 4EXT wipe feature not superwipe
(4EXT-> wipe|format ->format all partitions except sdcard)
then flash the rom

if its still fix the issue

flash an RUU (this will cleanup everything)

I wiped battery stats from 4EXT recovery which hasn't fixed this issue.
I will re-flash Android Revolution using your instructions tomorrow.

If my battery goes flat during an ROM install what's the worst that could happen, could I completely brick my phone or could I still access recovery to restore my ROM Backup, or re-install ARHD ROM from 4EXT.

If all that fails what would be a good RUU to flash? would I then have to make my phone S-OFF again?

Thanks for your time, it's much appreciated.

If the battery runs out just leave it to charge for a while. You'll still be able to get into recovery so it doesn't really matter I think

Before I seen your post I wiped batterystats.bin with the BatteryCalibration App from the android market and didn't do anything. As I explain below I got it to work with 4EXT recovery wiping battery stats, but I thought the Battery Calibration app did the same thing. In that case I think taking the battery out and in for a second time may have worked.

Actually I waited a little longer and my phone went down to 98%. I left it on overnight and now it's 63%. It looks like it's working again.

But with further checking I noticed a couple of other weird things.


If you look at my pictures above, here it says "Status: not charging (0mins)" & "Status: not charging (19mins)".

When I took them screenshots I hadn't had my phone on charge for over 10 hours. Oddly for very small intervals it's charging itself. At one stage I think I check it it was 75% then I checked again and it was 76%.

Something else that looks a bit odd is my phone temperature, in my screenshots you can see it says it's "11.9" & "11.6" degrees. It's over 14 degrees here in Australia how could my phone be colder than the temperature outside. I remember my phone used to be "26" degrees often. "11.6" dosen't seem right.

Do these two issues seem familiar to anyone. I know there not big problems but it would be nice to have them corrected.




EDIT: I decided to do a Backup in 4EXT and my phone was saying 55% battery and in 4EXT my phone says it was 62% why the difference? Could this be a problem? which one would you think is the correct one.
EDIT2: It did go down to 55% pretty quick while doing the backup, prehaps it needed time to work out battery life.
EDIT3: Now m phone battery says it's 72%, then it quickly went down to 69%. It never used to do this before I rooted. Could this case any problems, like the battery to go too flat to the point it's unrecoverable.

Sorry for all the edits and questions, I just like to understand my phone and be sure I don't break anything

Battery percentage fluctuations are common when you just change a rom.. Even after reboot if the battery percentage goes up then within few minutes the percentage goes to its actual.. The battery requires some time to settle so when you change the rom or kernel these fluctuations do happen(remember these fluctions are in numbers only the battery charge doesn't increase Actually)

Once you use a same rom for like a week or so.. The battery stats sync up with your usage.. So no worries

Also regarding the temperature it seems like the battery you have doesn't have temperature sensors (anker doesn't have sensors too so always temperature is 11C for me)

Anker does not have a proper thermistor.
