Weird battery charging issue (stuck at 83% in all ROMs)

So,
I've flashed three or four ROMs over the last week (with a few different kernels) and they're ALL having the same issue:
I use the "miagi method" to fully charge the battery, but when the phone is ON, the blue LED comes on when the phone is still reading 83%. I turn it off, plug in, and after a few minutes it's at 100%. I've wiped stats, flashed ROMs and kernels and the problem persists.
I don't know if this is having an actual effect on battery life, but it sure is annoying.

I'm going to assume you've been to this forum?
Personally, with all the phones, re-roots, re-flashes, and Odin flashing I've done I've had no need to do any battery edits, so I am limited on experience. My question to you is this: Does it hang at 83% for a while when in use, or does it immediately begin to drop percentage as if the battery never charged beyond that point? I know that sometimes after a reboot, my phone will go from 50% to 20%, but then hang at 20% for hours since it is in actuality at 50%.
If none of that helps you at all, my suggestion is this. I found the same thing for half the cost several months ago elsewhere if you look. It came with 2 batteries, one for me and my wife. The included batteries are notably not quite as good as the original samsungs. However, carrying an extra battery gives flexibility, and the wall charger does a faster and more effective job at charging any battery.
Plus, then you'll have a battery while you're other one charges!

++ on This .... I've used that calibration method (the 2nd one, off method) and it worked well for me.

hi i can solve this just follow simple steps
discharge your battery upto 17 percent
than use back camera with flash on take pictures with flash your phone will power off suddenly after 2 to 10 pictures.
just plug in charger issue is resolved your battery will be charged upto 100 percent

[Q] Not sure if I have found a battery drain bug or what

Something I've discovered recently, and I am not sure I can explain it properly, but here goes...
I am running SRF 1.1.1, I don't believe this is the cause of the problem, but probably something that should be stated.
So running SRF1.1.1, I usually get wonderful battery life. I typically use an external charger and swap out batteries when they get to around 10-15%. This has worked well for me.. For the past few days I got lazy, and just plugged my phone in and left it on my desk to charge, no problem. When the battery is fully charged and I unplug it from the charger, I noticed it was rapidly draining.... I am aware that often when charging via the phone the battery immediately drops to 96% when removed from the charger. So this is normal, but I've noticed that after unplugging from the charger I lose about 10% per hour, when normally it may be 1-2% depending on usage.
To remedy this problem, rebooting seems to fix this issue. I have also had success with the airplane mode toogle. I don't see any odd usages showing up in spare parts, but is there any other way I can test this theory?
Thanks!!
Edit: Wanted to add, that this only seems to happen when using the charger cable with the phone. Swapping batteries does not seem to produce this issue. It is only when the phone is removed from the charger.

I haven't calibrated by battery lately and thats exactly what mine does too, I would stick to the external charger because our phones charge excruciatingly slow unless off. Try calibrating by charging to full while on then turn it off and let it charge more and repeat that a couple times then boot into cwm go to advanced and clear batt stats

Is there an advantage to calibrating a battery if it is not being charged in the phone?

This is the TWS bug mixed with no battery calibration.

similar to what i have been experiencing. i enjoyed great battery life with srf 1.1.0. have a 3500mAh battery that i used to get about 48 hours out of, but now it is averaging around 25-30. i do not have anything but the stock battery to swap with, so i do put it on the charger nightly now. i was planning to recalibrate the battery tonight to see if that cleared things up.
what would be a way to fix the tws bug?

I have noticed this too. It seems to srf seems to not like my extended battery. I am lucky I get a day out of it. I some times will plug it into one of my work computers just to bring the charge up a little and it starts flashing red and discharging this is only on my extended battery not the 2 stock ones I have. I have even tried different kernals to see if that was issue it isn't.
Sent from my lean mean drunken machine useing XDA Premium and a 12 pack of Sam Lager

in looking at battery usage in >settings>about phone>battery use>cell standby i see usually 0-5% tws.
one thing i have noticed, though have not tested is that the screen appears brighter, even at the minimum setting than what i remember from srf 1.1.0

[Q] Battery worn out?

Hello,
My desire, after:
an inability to restore nandroid backup
a possible corrupted sd card
a usb brick and inability to mount some nand partitions
and finally succeeding in fixing it, now using/running:
2.29.405.5 stock rooted rom
a new sd card (samsung 16GB class 6)
clockworkmod 2.5.0.7
s-off
seems that has battery issues. When it reaches below 30%, it drains a lot faster. In example few minutes ago, the battery was below 30% level and after sending a couple of sms messages the phone, without the "Connect the charger" indication shut down. Not even the battery icon was red.
What should I do?
After flashing the above ROM I ran an app called battery calibration (could this be the culprit?).
I haven't experienced such problems before the whole mess mentioned above.
Thank you for your time.

Well, it seems to me like a "classic" battery meter calibration issue.
TVTV said:
In order to calibrate the battery meter - FYI the battery itself cannot be calibrated, as Li-Ion batteries have a very low memory compared to old Ni-Cd etc. batteries - you have to go through the following procedure:
1) charge the battery to 100%;
2) let the battery discharge until the phone shuts itself down;
3) plug the wall charger into the phone, boot the phone up then charge the battery to 100% without interruptions.
If the above procedure does not yield the expected results, you can try fully charging the phone (LED showing green) with it completely turned off (after completely draining it). Again, the charging procedure should not be interrupted.
Source: personal experience - had to do this twice after installing new ROMs, as the phone was shutting down at ~14% (working like a charm now).
Regarding the matter of battery wear because of complete discharges, Li-Ion batteries do indeed have a lower cycle count than old-school batteries, but the standard charge/discharge number a Li-Ion battery can take is ~350, so you can't damage the battery pack by doing a full cycle per month (required to keep the battery meter accurate).
Good luck!

Did this work you mate? I have the same issue with my year old batter now... the phone shuts down @ 40% without any warning... and when I charge it, it starts from 0% and as soon as it hits the 58% mark, it jumps to 100% by itself... and i cant seem to figure out what the hell could I do to fix it... I tried calibrating the battery using the awesome method described here http://forum.cyanogenmod.com/topic/11823-battery-calibration-thread 3 times and nothing changed...

bump bump.. i really need help on this guys... :/

Weird that after calibration you still get that kind of issues, does this only happen on your current ROM? I have the latest CM in my desire and everything works just fine... Maybe try another ROM if calibration doesn't work to see if it's a hardware or software issue

i actually had issues with MIUI first.. the phone randomly shut down by itself but when i turned it back on, it was perfect... then i switched back to Oxygen and while everything was fine, suddenly one day the phone died at 40% :S and from that day on the phone charges to 58% and then instantly jumps to 100%... and as soon as it gets to 40% it shuts down itself... i guess i need a new battery but i wanted to see wether i can fix this one somehow so i can use it till the new one arrives...

same problem
i have the same problem
my phone turns off at 20% battery
calibration does not help....
and battery is not bad - it works fine
i'm sure its the problem with calibration

phone turning off at 20% is fine mate because thats the battery guards against any damage
most of the phones ( smart phones) switch off at 20% as going lower can damage the System .

It shouldnt normally..It's supposed to work fine upto 5%

Have a look at this, it worked for me (but you need a compatible kernel, most AOSP are so)

My phone does not like extended batteries

Hey all,
I have done some searching around here and on the web but have not found anything (with a solution at least) similar to my problem. First off, here are the details on my phone:
SGH-I747M Galaxy S3 unlocked on Telus
Rooted on stock ROM
Running JB 4.3
Currently have CWM 5.5.3.7 installed
Now the problem:
My phone does not seem to enjoy extended batteries. I have attempted a few replacement batteries from battdepot.ca (their replacement is a 3.7V 2300mAh) and two of the Hyperion 2200mAh 3.7V replacements all with the same issue. I have sent the batteries back and had them tested and even had new ones sent to me and still the same thing happens so I am certain it is my phone. I have had this issue since before I rooted the phone and was on JB 4.1.2.
I charge the battery overnight every night and it usually says 100% in the morning. When I unplug the phone the battery percentage immediately drops down to 88%. When I get to work about 45mins later and look at the phone, the battery is usually around 94% (it always creeps up slowly to a max of 94% after unplugging it). If I plug the phone in at work it will go up and down between 96ish% and 84% but will not go back up to 100% unless I leave it charging for the whole work day... mostly it will then just hang around the 85% mark. Most times I still get pretty decent usage but other times the battery percentage will drop from 94% down to 15% and below.
I have tried "calibrating" the batteries to no avail. Has anyone else had this issue? Is there a way to fix it? I only have this issue with batteries above the stock 2100mAh.
Any help is much appreciated!

Battery readings inconsistant with new battery.

Hi.
Having my Note 2 for some time now I can understand that the phone is failing in some manner. Maybe someone can answer some questions I have. I had some problems with a failing battery that eventually became bloated and chucked it out. Bought a newer third party battery but It did not work right. After that I bought a original battery and it looks as original as I can see.
When my first original battery was failing I was getting wrong percentages and sudden voltage drops as expected with a damage battery that could not hold its charge anymore. With the third party battery I still could not get it right or just did not gave it enough time to settle in.
With my newest battery still get a sudden voltage drop but then it climbs up again when I read it with a software monitor. It charged as normal to 4.3mV (100%) and then a sudden drop to 3.7mV (70%) in those fifty minutes then it climbed up again to 4.2mV but the percentage gets stuck on 69% until the mV reaches the actual percentage.. I still get several days usage out of the phone until it needs a recharge so that is not a problem. I just like things to work as they should if it is possible. Googled around but the results I read mostly went into resetting the phone, back to factory setting or wiping several things. Already tried those things.
I was just wondering the following...
- Could this be a hardware malfunction..
- Should this eventually stabilize after several charges.
- Does the voltage drop indicate a bad cell.
- Has the battery lost its full capacity since it old stock.
Maybe someone has some insight or it is just as it is and I will just accept it.
Thanks.
