NOTICED WEIRD BATTERY STAT i9100!! - Galaxy S II Q&A, Help & Troubleshooting

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.

Delete.

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

Shuts off randomly. Is this a swollen battery?

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.

I have a Sprint Galaxy SII (Epic 4G Touch) and have been having the same issues. My battery is also swollen and I have been trying software fixes for a couple of weeks. I ordered a new battery and am glad to find that your very similar problem was solved that way.
Thanks for posting about this!

Major battery drain when rebooting

Hey this is my first post on xda
When my phone freezes for abit it automatically resets itself which i suppose you can consider normal. But after the reboot i have to connect charger. I can have around 70% charge but after the reboot its more like 10%. I have also gone through 3 genuine samsung batteries in the past 3 months. I can only put it down to bad phone voltage.
I have had this problem with my SII for the past couple of months. Its around 16 months old and not yet due for an upgrade so im hoping to fix it.
The pictures show my battery dropping around 30% just because my phone became unresponsive and would not work so i restarded it.
Cheers in advance, Chris

Happened to me quite a few times too. But mainly because of I was on a non stock kernel.
Would want to know whats occuring within it to cause such a drain.
Maybe its a battery calibration issue. It was not discharged instantly but the reading was inaccurate. ?
Have to tried recalibration techniques?
Post your ROM and kernel details; Goto Settings - About phone, and post everything you see
Nothing to worry about. The fuel-gauge chip just gone crazy.
Cheers for the replies. Heres my info

Yes..agreed fuel chip gone crazy. Here is my screenshot. Discharged instantly when rebooted or as the system read it. Then without charging the battery reading gradually increased..!! Strange

Assuming you have rooted your SGS2, have you tried to reset the battery stats in CWM?
Battery stats is the file which is responsible for battery graph in settings. So deleting it won't help.

[Q] A Very very Wierd Problem...Please Help !

I was really suffering from massive battery drain....see here - http://forum.xda-developers.com/showthread.php?t=1933012
ive now found out that i am having a very wierd problem...My rom is showing some 30% battery while 4ext shows 50%......Sometimes it is exactly the opposite....Once i discharged my phone to 2% (rom reading) and when i saw in recovery it says 17%....
I have completed many many cycles of battery from charging to full....and discharge to 0.....Also i used the battery callibration app SEVERAL times!!!!........But nothing seems to work...
Can somebody help...Please
I am really suffering from massive battery drain http://forum.xda-developers.com/showthread.php?t=1933012 :crying:
Did you try to delete battery stats? Or use an app to improve battery life?
I have the same issue too when booting into recovery. I don't worry about it. I suggest the same as Ramjet in your other thread.

I had this issue with my old battery and old charger,
Now I dont use my phone while charging , I charge other batteries with the wall charger while using other ones and everything is fine now.... battery % seems to be same in both android and recovery.
I have that same issue too. Lol maybe the recovery can't read the battery correctly. It'll show up higher in recovery and then when I reboot, it will read the same way like in recovery. Tried numerous batteries with the same result. Although I havnt tried battery calibrating. Ill give that a shot.
Is there any solution ??
Try klect's solution and go into recovery, wipe battery stats. Then let your battery drain and die. Then charge your battery back to 100% with no interuptions like pulling your phone off the charger too soon. When you wipe your batt stats you are getting ready to recaliberate your battery. After you let it charge to 100 percent. Let it drain to 0 a couple times to recondition your battery.
You do know that the evo 3D gives around 3 hrs of screen time dont you? even on stock rom on normal usage. If you have the wifi on all the times you'll get around 2:30 maybe 3 on a full charge.
Your battery certainly is draining faster than usual but have you tried keeping it idle and seeing what kind of drain you get? From that screenshot in the other thread it seems like your phone is getting some heavy wifi browsing or something (and do check if facebook or email apps are the culprit. Having push email on drains a lot)
And the recovery/rom reading wrong stats happens all the time. just recalibrate your battery like these good folks here have already suggested
Yes i keep wifi on all the time...
But once i kept my locked for abot 3 hours after full charge...when i unlocked it showed 99%...i was happy and i didn't do anything just surfing my screens it dropped very very fast to some 70 % !!!!
Also please hit our thank you buttons please. Even if you didn't get the exact answers you wanted. It's appreciated for helping one another.
you really should check your apps battery usage using one of the apps ramjet73 told you about
ramjet73 said:
There are a bunch of tips here.
Usually that kind of drain is caused by an app. Try running a stock ROM for a day or two and see if the issues go away. Or use one of the battery monitoring apps (BetterBatteryStats, SystemPanel Standard, Battery Monitor Widget) to determine which app is causing your drain.
It may take some work on your part to isolate the problem since there is no global solution to battery problems.

top culprits are mostly facebook,email exchange,google maps and pretty much anything that syncs alot
Also try using you phone on min brightness auto brightness is also a battery killer
I cant beleive no one asked you this but which kernel are you using? And is it overclocked?
I am on mwakious 13.1 default...no changes to it

Battery problems after fleshing custom rom

Hello. I got a lot of problems with my battery. It was all fine until i rooted and flsahed a custom rom. I flsahed jellybam and wiped cache data battrey stats and everything before. I get a lot of random shut downs and reboots and battery percentage drops. Sometimes its at for example 80% and i don't use it its in my pocket and it just shuts down. Or it sais it has 30% 40% and i receive a call or sms and it gets to 1% and shuts down and when i turn it on it has again 30 40% or slowly gets to that percentage. I tried aokp, jellybam, rainbow rom (something like that) rootbox and tried dorimanx and siyah kernel. Now i went back to stock rom and krenel but the problems are still there. I attached a pic of my batt stats so pls if anyone knows what could be the problem please help.
Edit: i tried calibrating the battery with an app and manualy shutting down the phone charging the phone to 100% and remove the battery a few minutes but that didn't change a thing

Nice picture, where is that? the Alps?
Sorry for the late reply i had some other stuff going around. I tried resetting the fuel gauge chip with extweeks while on siyah kernel and that didn't change anything, i tried a few more roms and kernels but the problem remains. Now i am on resurection remix 4.0.4 rom with flexy kernel and i tried reseting the fuel gauge chip with xxtweeks and again nothing changed. I guess this is a problem with the phone becouse with different roms/kernels the problem is the samo. Lately its getting worse. The phone is on the table with 80% battery and i just hear the low battery sound and when i unlock it its on 12%, and than goes to 5% and lower and shuts down. After restart it has again around the normal 80% for example. Also one day i charged it to 100% and as soon i unpluged the charger it dropped to 0% and shut down. Could it be the battery or is something seriously wrong with the phone? Thx in advance

Could be the battery.
Just try another battery from which you know it is working in your phone, and then try your 'faulty' battery in a phone from which you know it is working. This way you will know at least if it is the phone or the battery.
Thanks for thr replay. I guess i‘ll just buy a new battery and see how that goes because i don't have a spare s2 and battery to try

I've been experiencing the same problem with my SGS2's battery and noticed that it is getting bloated. I purchased a new one to prevent severe damage on my mobile phone.

Screen flicker and device shutdown

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.

I have tried a lot of battery related apps. BBS is one if them. I haven't seen anything unsual. In fact I've also tried apps like greenify. However battery life in the first 60% of battery is actually good. After 40% comes the problem.
