Hi,
I have a GT-I9100, running CM10. This has been working great for weeks (since first CM10 experimental). Some time back I started experiencing problems while charging, and I thought it was a faulty charge port. This problem magically "solved" itself, but now I am experiencing random shutt off, freezes, part of the screen going black before it turns off completely. Some times I get to the boot animation, some times it turns off and works for a while, before shutting off again. Tried a complete wipe/factory reset, to no avail. The battery stats also seems pretty random, going from ~70% to ~10% after turning off and on again.
I was reading here (http://support.t-mobile.com/docs/DOC-3152 (I don't own a T-mobile)), and it said this could be caused by a faulty battery. I have taken some photos of the battery here: http://imgur.com/a/FVyK0 ... To me it seems that it could be some visible swelling to the battery, but I don't have anything to compare it with. Any opinions??
And could a "faulty" battery be the cause to these problems (which to me seems to be software related)?
Which kernel are you running?

1. the battery is a little swollen at the middle
2. use a thin a paper to support the battery to ensure proper contact with the gold pins. this might resolve the random shutdown issue
Did you undervolt and/or underclock CPU and/or GPU? If yes, less aggressive values may help.
The crazy battery percentage can be solved by charging your phone to 100%, then clear battery stats and reset your fuel-gauge chip.
Tell me if this helped or not.

I installed the latest CM10 build today, 10-20120821-EXPERIMENTAL-i9100-CODEWORKX, kernel 3.0.15-CM-gea1d0d7, baseband I9100XXLQ6. I have however experienced these problems on other CM10 builds, but before I started experience them, I was running CM10 without any problems.. I could downgrade to CM9 and check I guess...

I don't think it's in any danger, it happens in old Nokia phones. I personally experienced this in my old n95.
It looks like as a result of too much heating, maybe

I have been checking out calibration, but there seems to be some diverging information. Should I charge it 100% while using it, or while off? Should I first drain the battery? And what do you mean by "reset fuel-gauge chip"?
As you can see, these battery stats don't seem right: http://imgur.com/Xnv6W.png

Wow that's the exact same thing happen to me.
The phone would shuts off by itself at random battery percentage. then I try to turn it back on, sometimes it just shuts right off.
At other time it would continue running with the battery slowly increasing. The graph of battery usage is really similar to yours. It would have those "valley of death" and then comes back alive as a short lived battery.
I am trying the battery reset by draining the battery until the phone really cannot be turned on (even the monitors), take off the battery for 2 minutes, charge it while it's off, unplug as soon as it reaches 100%, charge it till 100% again. I have read other thread saying that the taking out the battery part is at the end of the charging (100%), not at the beginning (0%). So I don't know which one is correct way to reset the battery.
Before update, I did not experience this prob, but only really hot cellphone while charging and fast draining battery even with 2x battery apps. Well, I had like 100+ apps, so it's understandable, but now, I have a very few apps (10+) but it's doing this magic trick to me.
Oh, and I noticed my battery is swollen and bulged at the middle too.
Anyone has an answer if it is a battery problem or just my mind going crazy?
I'm having exactly the same problem while running CM9. However i've noicted that the same thing happens while running stock as well. No overclocking or undervolting here.
My battery is swollen as yours is as well. Could it be a faulty battery?
Looks like it was the battery after all.
The service centre lady told me that my battery was FUBAR. Bought a new one and the problem seems to have disappeared.
She said it happens because of overcharging. Is that true? Thank god the battery was cheap.
It was the battery for sure. Ive been getting amazing battery life ever since I bought the new one. No more unexpected shut downs or any of the problems i was having.

Hi guys I have noticed a strange Battery status..
I had my battery percentage showing above 50%
Then I switched off the phone,
took the battery out for a few seconds,
put back the battery and switched on the phone.
The battery was down by 15-20%
Then it started to gain a few percentage (upto 5%) of battery without me putting it to any kind of charging point/data cable.
What kind of weird thing is this in the Galaxy s2.
I am using Android 2.3.5
Simple&Clean v1.3
Speedmod k2-16
I have also attached a screenshot of it.
Please tell me why is this happening cuz this happens every time i take my battery out.
Thanks
nah, its ok. just a bug which happens sometimes. happened to me many many times.
Or if you are constantly overcharging the battery it will happened .

You can't overcharge if your phone is working right. Its probably just drift in the monitoring circuit.

It's due to Samsung's built in battery calibration. When flashing firmware cwm can throw battery stats off, but after using the ROM for a while it will auto correct itself. Nothing to worry about dude!

hey djsherry, did u figure this problem out? because I have the same and if you (and others) have a close look at your screenshot your phone shows the same amount of time both for elapsed and remaining time on battery!!! Thats a weird situation, I have read hundreds of threads and still couldnt figure that out! Anyone??? Must have a problem with the hardware (battery monitoring) or with the battery itself?!?
Search before posting please, nothing weird about this. It is well documented well understood behavior.

Its common, resetting your battery gauge will reduce this to some extent

I got this phone Friday.
I didn't root it Saturday but it was in the back of my head. Before I rooted it, I noticed that the battery life was the worst I had ever seen. I read online that this is a bug in 2.3.6 (good job samsung).
It charged while I was watching some TV, so I rooted it and installed UnNamed. This knocked me down to about 50%. I finished off the battery playing games. Then charged it back to 100%. When it was roughly 58% it froze so I had to pull the battery. When I turned it back on, and the battery was magically at 29%. Which seemed odd to me, is it just inaccurate or how does that work?
The hell is wrong with this phone? Nothing gets to me more than bad battery life. If I can't get this resolved, i'll have to bring it back to AT&T and swap it out for something else.
no advice for you, but mine is going on ebay when the htc ics phone comes. I haven't tried them yet. oh, I'm importing all phones from now on, too.

Sent from my Galaxy Nexus using xda premium
Most more than likely it's the wiring leading up to RAM processor, and, consequently, the flux capacitor, which is probably where your problem is. The flux capacitor is what regulates the battery input/output which can sometimes lead to poor battery life, disappearing battery percentages, and in certain cases where your last name is McFly - time travel.

Search is your friend, this is a well documented situation. In short it's how li tech batteries work in combination with how our fuel gauge works. (it goes off of voltage vs counting mah, and there's voltage sag under high current draw, this equates to it showing lower than it is on reboots at low power)
Battery percentage artificially reports low when the device is rebooted on low battery. This is widely documented on these forums.
If you're returning the phone because of this one small minor glitch, good riddens.
Also, Unnamed 2.x is not immune to the BT-AMP bug that kills battery on UCKK6, since it's based off of UCKK6. This is why many reverted to Unnamed 1.x
And why did you post a new thread on this? There's a dedicated thread for UCKK6 battery issues.
You need to be patient dude. Use search and read through all the related posts in this forum. You can begin with flashing the rooted stock 2.3.4 with KH7.

It's a minor hardware glitch that happens only when you reboot your phone on low battery. Solution is:
1) Accept the weirdness of your battery rising after the glitch
2) Reboot when on charger if the battery is below 50-60%
3) Reboot at a higher level of battery
You didn't magically "lose" 30%+ of battery - that's impossible. You just had the estimate of charge level thrown way off.
As an example of what is possible - right now my typical drain is well below 1%/hour when the phone is sitting in good signal. In weak signal it's about 1%/hour.
Man I don't know what the deal is I'm on this thing gaming web surfing and other **** and I got my wife saying "Your always on your damn phone " and I get 18-20 hours per charge

It is, as I've said before, the one corner case where our fuel gauge fails. It's the small price we pay for NEVER having to worry about battery recalibration - it will always converge towards truth, the only problem being that high load after a reset (rebooting on low battery) will throw it off for a few hours.
Hi, I got a very annoying problem.
Since a few weeks ago, flashed a ROM and when I've tried to use the phone, it keeps turning off randomly, sometimes after a few minutes, sometimes after hours. So, I tried to take it back to the clean original 2.3.3 ROM, but it keeps happening. ¿Any idea? ¿Any solution? Please, help me.
Oh, something else, it only happens when the phone's used with the battery, when it's attached to my laptop and used as modem, the problem doesn't appear.
I had the same problem, it said android system shutting down. I just bought new battery and it works.

go back to stock and see if it helps! try to troubleshoot the problem! Also, don't install any apps!
There are instructions on how to calibrate your battery in the first post in this thread:
http://forum.xda-developers.com/showthread.php?t=1489214&highlight=calibrate+battery
If the problem is the battery, you might find that after calibration that the battery drains faster than expected, and still shuts down, only this time it warns you that it's gonna shut down. This would then be the true battery drain. If that is the case, you might just need to buy a new one anaway.
Otherwise, I don't know what else could be causing those symptoms. (Other than an electrical fault, from accumulated damp or something)

thanks so much..............
What happens it's that the phone shuts down suddenly, the message appears for a seconds and it's off. Wait for a few seconds, try to turning on again and sometimes works for some minutes, and sometimes it's keeping turning off, and off, and off. But, the battery level seems to be correct, I mean, when I turn on the phone after one of these sudden shutdowns, only drains the logical ammount of battery for starting use the phone.
I think... if the problem never appears when it's attached to the laptop and charging constantly, and magically appears when I used the phone with the battery, it's probably just a battery issue, right?
I have a similar problem to this, my phone randomly shuts down after showing the 'Android System shutting down' message but sometimes loses ALOT of battery. Last night it went from 78% to 8% after shutting down :/ I noticed it happened more often when im playing games or taking a video, things that take up more battery. When i keep it plugged in it keeps awake so the problem stops but i cant keep it in all day every day. I dont really want to buy a new battery until i really really have to, but I have had the phone and battery since the x10 first came out about 2 years ago, so anyone any other ideas? Thanks

Yeah this happened to me before about 6 months ago, so i went to my provider (3) and they sent it away to Sony Ericsson and they sent me a whole new phone but I didnt want to do that again really, but i may have to. When im not using WiFi or 3G then it works fine, and when its plugged in to the charger it works so i guess its a case of not usuing the internet when im not near a charger
I have the same problem.
My X10 reboot random when using 3G (Wifi is still OK) and Gaming. Now i'm on Stock 2.3 and stock kernel and....wait. (Flash some ROM and change the new battery....but not solved )
Anyone help us !!! Plizzzzzzzzzzz
Maybe your solution
I had the same problem sometimes with original kernel after 1 year of using my phone.
Then i tried to install a new rom, and i was thinking the problem was solved. But it was not...
I finished by trying the X10S (v7) rom with DoomLord kernel (1113mhz) and this problem was solved...
I tried some kernels and this one was stable with a good battery life and no shutdown problem. With some other kernels i had this problem back.
So I think that kernel could be the problem.
Infortunately, with the rom X10S v8, Doomlord kernel cause issues with wifi (unable to get ip adress). So now i use kCernel-SE-stock-mod-v1 and no shutdown problem anymore.
*Maybe the solution is*
Try to change your kernel with one of thoose :
- kCernel here (in "2. kCernel-SE-stock-mod-v1")
- DoomLord (search fo x10_gb_DooMKernel-v06-1113_wifi.zip)
Note :
- With this two kernels, you'll have to download appropriate wifi patch and install it from SDcard via xRecovery
- don't try to install X10S v8 if your bootloader is locked
So, try to flash your X10 using flashtool with Doomlord kernel
Tell us if it worked, i hope it solved your problem as it do it for me.

Hi,
I have had this issue too, for the last few months. No matter what ROM/Kernel, batt stats cleared, etc, still the same. Can idle all day, but as soon as I use 3G, GPS, or use any intensive app, she shuts down.
As an experiment I installed a battery monitor that plots graphs of % charge, temp, voltage, etc over time.
I had a close look at my logged graphs and have noticed that just before each reboot, the voltage seems to dip drastically. Battery charge is fine, does not seem to matter. but a sharp drop in voltage occurs. Increased draw for the more complex tasks (3G, GPS, etc) seems to be tripping it up.
As the Battery is now 2 years old, I figured it is just starting to fail? And iv noticed lots of people are suddenly coming out and complaining about this issue.
I just ordered a few new Batteries from 'Ebay', will see how we go!...
peace.
[INFO / SOLUTION] Suddenly shuts off with red LED.
Good to know:
The X10i/a have now reached an age, where battery failures is very common nowadays. Specially if one got the device early on or just after the launch.
Symptoms of a failing battery:
* Device suddenly shuts off, even when the battery have several percent remaining.
* Device drains fast, even when not used.
* Device might just shut off for no whatsoever reason when doing something that draws a lot of power, and will restart just fine.
* Device has a surprisingly fast charge time from empty to full.
When the device shuts off all of a sudden, it's followed by the indicator LED blinking red, rapidly three times, and might repeat this at restart attempts.
Sometimes it takes several tries before the device starts up again. Battery just needed a few minutes/an hour of "rest".
There's nothing wrong with the device.
Just get a fresh replacement battery and it'll work just fine again.
But beware:
There are many fake batteries out on the market, claiming that they have higher capacity, yet very slim in size.
There's a simple rule when it comes to battery capacity:
More capacity = larger in size, which might need a special back-cover. There's no escape from that.
If one would happen to find a such incredible slim battery with super capacity, the battery security circuits and/or chemical makeup probably have been circumvented/changed, and have a high risk of catching fire and/or explode when charging/discharging.
Yeah thanks for all the advice and sharing your problems. My phone does reboot alot when im using 3G or taking a video. Recently my battery would reboot, drop alot of percentage and then increase percentage without charging...magic I dont really want to buy a new battery because my new contract starts in june i think, but maybe il have to.

Hi xda! So I've been having a problem for a couple of months with my SGSII and i have searched a lot but i haven't found a solution yet.
The problem is that battery behaves normally and has a normal drain rate, but when it reaches 40% more or less it drains massively and drops to 10 % (more or less, could be 11% or 9%. It is not something precise and accurate) and screen immediately starts to flicker, backlight as well, then the signal is lost and phone shuts down. After that i can not turn it on unless i charge it.
I have looked a lot and pretty much all of the forums recommended to buy a new battery. I bought another battery (original) and the problem still continued. I've also tried swapping batteries with a friend, but the problem still happened to me and not to him. Also I have tried a lot of Roms, I've tried going back to stock as well, but still nothing.
Currently I'm running Cyanogenmod 10.1 RC2 because it gives me the best battery life in those 60%.
I leave you an attachment of a screenshot. As you can see battery percent dropped a lot at the end, and i wasn't using it heavily.
Thank you in advance.
It is a hardware issue, I had the same problem (battery would drain below 10% though), sent it to Samsung, Motherboard and Charge Socket got replaced, I don't know which one was causing it because I had other issues like broken home button too.

May be there would be some hardware related problem. But why dont you give a try to to a wakelock detector app like betterbattery stats or wakelock detector? Atleast you will know which app is eating your battery or is it a hardware related problem.

Before I was using 2000mAh battery but it bloat out so I bought a new 1650mAh battery. The problem is that it just turned off when it reaches 40% without even prompting a low batt notification. I thought I bought a defective battery so I purchased a new one again, but it has the same problem. I was using custom roms btw and flashing CM11 nightlies every day or whenever update pops. Does it affects this or should I just recalibrate the device because my old 2000mAh.
Thanks for the help in advance.

Is this a genuine battery. You could try resetting battery stats or use dorimanx kernel to reset fuel guage.
Thanks for the help in advance.
Well the first battery i bought was just a class A, the second battery I just bought a while ago is genuine and its the same result. I will try to flash stock ROM and see if it still occurs, now I just tried calibrating the battery stats.

Don't they say resetting battery stats has only a placebo effect?
I'm having exactly the same problem. I bought two new original batteries and the problem persists. It just doesn't happen with my 2011 original battery.
Thank you
Well i read some articles that returning to stock rom should fix it well im still experimenting on the problem.

Did you check the battery voltage level just before 40%? If I understand correclty, my guess is that the battery should range from 4.1 to 3.3volts, as it has been specified as 3.7v.
In my case, it was around 3.6 volts when close to 40%, which seems to be a reasonable voltage for 40%. But then it suddenly drops to 3.2v (which I measured with a multimeter, since the phone goes dead at around 40%). I have started to beleive the battery is the problem.

Well sad im no electricity expert, so I dunno how would I measure it. Im considering returning the original batt i purchased, I will see if this still persist. Thanks

Battery voltage can be measured using apps like cpu-z and go to the battery section. Software readings are slightly less accurate than multimeter but does the job anyway. 3700mV = 3.7V (conversion of mV to V)
