Either it's fuel gauge or the battery is faulty.

But i can use my phone for a long time on even 4%. Wtf lol?

Then it's battery fuel gauge.
Told ya, it's one of those.
My battery % starts increasing after I unplug it and no, it's not because of wireless charging, plain fuel gauge.

Thanks, how can i repair this?

By wipping the battery stats via CWM or stweakes

I've been having this same problem, and went back to stock 4.1.2 trying to fix it. I'll flash Siyah Kernel again and see if I can fix it that way.
I've been trying out different ROMs trying to fix it, but it turns out all the flashing may be whats causing it. With Supernexus 3.0 coming soon, I hope it works!
Thanks!

My phone did this 2 days ago after I wiped and flashed to the newest unnamed ROM. I was around 57% before, after the reboot and going into the phone i was at 12%. let it drain to 3% and charged it over night. It's been fine ever since then.
But i still dont understand why drop so fast? Do you think is normal?

The fuel gauge sometimes glitches... Did the raw voltage reading suddenly drop?
First was 50% for example and press OFF power and re-active phone and i see already 12%.
I dunno where can be wrong...anyway i hope wont happened next time. Today is first day i saw this strange problem.
Could be a problem when i restart phone sometime..
If problem still continue then im gonna think to buy a new battery standard i guess isnt? Any suggestion?
Battery is fine, it happens to many people. I would guess it has to do with booting the phone, as it uses a bit of battery power to reboot, and the raw voltage of the battery dropped alot, which caused the fuel gauge to drop down, but as the battery voltage slowly went up, the % stayed the same.

[Q] Battery problems

Good evening all.
When i'm charging my battery with wall charger our pc charger. I cant fully charge to 100. Its saying fully charged but after i unplug its going down to 96 our even 65 percent. And another thing was when is was charging my battery it was at 86 and after that the battery was going downwards instead of upwards ( when in charger ). So i searched on the internet and i found a way to calibrate the battery,turn off foon let it fully charge,take battery out 180 sec and put back in and it should be calibrated. But my problem is i cant get it fully charged because its getting downwards. Even now its stuck at 81 percent and not going furter. annyone got a solotion. Thank you in advanced.
I hope you get an answer, I have had this problem before but changing ROM seemed to fix it...... Please don't ask me to many questions if any, I'm pretty sure I'm more of a noob than you

Thank you,ive tried that already. I am thinking to go back to gb and see how that works. Realy dont got a clue what else to do. And i'm completly new to this,so i'm a noob. hehe
The standard answer you will get from most people on here is "its been covered many times before."
However, I will tell you its the fuel gauge chip. Several charge-discharge cycles should correct the issue. Very common when swapping ROMs.
For example, for the hell of it, I just reset my chip and dropped from 63% to 2%. The chip kind of "learns" over time what full charge and empty is, and drifts about a bit until its fully sure what 100% and 0% are.

try rest battery history from recovery mode>>>advance
Also did that advanced wipe battery stats. Diddent seem to work out.
Thanks reverted, bij resetting the chip.
Do you mean, wiping battery stats?

Resetting chip,do you mean wiping battery stats?
Sent from my GT-I9100 using Tapatalk
No, just fully charge it, then let it discharge completely, charge and repeat, it will sort out its misrepresenting charge after a couple of full charges.

I'm trying to do that,but battery wont charge completly.
Its going downwards after reaching 82 percent our even don't load.After a couple tries its charging again but not to 100 percent.
So when i reach the limit when its going down again pull out wait till its empty and try again? At a sertain point it will be charging again till 100?
Btw sorry for my bade english!

Did you try turning the phone off and then charge it? After that do some charges when the phone is on like stated above.
Yes m8 i did,and trying it again right now.
The weird thing is,when my foon is on. The battery shows like 49. And now i turned foon of,and its seems like the green battery is like 15 our something. I also did wipe battery stats again. And whent back to a stock rom.
I would buy a spare battery, you'll get an official 1 for £10 to £15, that way you have a spare and will also be able to set if your phone or battery has a fault.
With my battery I did few bump charges (replugging it back in after it says 100%) and the battery life is excellent. I don'the let it drop below 15% if I can help it.
Good luck

Problem solved i think.
Got me a new battery,charged on a wall charger (not cable) and it was showing 100 in the phone. Then i charged my origenal battery on a wall charger (not cable) And was showing 100 to in the phone.
Now i found out that my charge conector on the phone,has a bad conection.
So i think thats why it issent loading our stops loading at a sertain point.
Sending back my s2 and hope to get it back soon.
Thanks you all for the help. And have a nice day.

Battery doesnt charge full?!

Hey guys..
I noticed something weird on my galaxy s3. Whenever i charge my device till 100% and take it off from charger, it goes down to 99% immediatly. I thought it could be a bug in my current rom so i flashed another one. But the buf still exists. I even changed kernels. Still same problem. I am running latest foxhound rom
+franco r5 kernel right now.
Is there any solution for this bug?
Hope someone can help me.
Best regards

It is not a bug, that's how it is made.
If the phone charged to 100% and sat there for a long time, the battery would lose charge cycles and life faster. So what it does, is one of two things:
It will either NEVER actually charge to 100%, or
It will charge to 100%, take itself off the charger to about 95%, and then charge again to 100%, over and over.
HTC does the second one, I think the S3 does the first.
Thanks for the answer.
I didnt know that. Its just so weird because on every of my previous phones the battery stayed on 100%.
But anyways thanks

I know, I don't like it either haha. Some phones will even say "100%" right off the charger even if they're not actually at 100%, which is why sometimes you see people that take their phone off the charger at 100% and a few minutes later they are at 95, etc.
There have been a lot of questions about this in sammy roms, and also in the s1. And it got me thinking about it this way.
As soon as you disconnect the phone from the charger it's dropped to 99%. But in my head, I say it has had to have even used the most minimal amount of juice and is 'technically' no longer at 100%.
Some are saying other phones are reporting batteries on 100% for up to an hour after disconnecting from the charger. That might look great, but there is no way that is correct either, because it has to have used some juice in that hour.
Maybe samsung don't like pandering to the needs of the masses re battery use reporting. Maybe sammy is the only one reporting a correct level.
Me, I don't care. My phone lasts just fine. Are you getting better battery life than your last phone? Haven't I read that the 1x has ordinary battery life? Does it's percentage stay at 100% for a long time? If so, that would be a bit of a rip off to me.
I know sammy have included the option to show the battery percentage within the settings of the s3. I don't use it, and my battery indicator stays at 100% until the battery reaches about 90%. Works for me.
Batteries never charge to 100% anyways to avoid the battery over-charging and exploding

SGS2 Battery drain and charging problem

Hi, two weeks ago I dropped my SGS2 to snow and it was there 2 hours :/ After that im getting strange problems, my last 10% of battery drains in minutes and last 3% in seconds Second problem is that when battery is so low that my phone dies it wont charge, it only shows battery and triangle icon. I have tried 2 different ac chargers and usb chargers and tried even my girlfriends s2 battery, I have waited for 1,5 hours charging and the triangle icon is still there. I have used my girlfriends SGS2 to charge my battery. I always charge 5-10% and plug it back in my phone. I dont have any problem if I dont let my battery go under 15% anyone have similar issues? If some circuit is damaged is there anyway to replace / repair it? And sorry for my bad english
Sent from my GT-I9100 using xda premium
Now my phone didn't wake from deep sleep, power was on but I need to reboot it. battery was 100% before and after 20min in deep sleep and reboot it was 85% I increased 100MHz, 200MHz and 500MHz by 25mV
to see if 1 of many problems goes away
Bumb
when was this snow drop?

Like I said about two weeks ago.
Give the guy a break and leave it off for a day, battery off and all. Stuck it in a ziplocked bag of rice. Can't hurt to try.
Mine was under the rain last monday, everything's fine but I'ma do it anyway.

Allready tried, but I noticed that the charging problem have magically disappeared Only strange battery drain left :good:
Im hoping it to disappear when stable CyanogenMod JB comes out
yeap, check the fuel gauge. Glad to hear it's all good now.

About week ago I reseted fuel gauge chip and noticed no change, I googled 2 hours and I find post about the same problem. Someone said that it can be software related issue and can be fixed with reflash. So I wait for offical jb update
Sent from my GT-I9100 using xda premium
Yeah, it's about to roll out any time now.
Now after 2 weeks of fuel gauge chip reset all problems have disappeared and battery life is very good. Now I have 70% left, phone have been 1d 2h on battery. I have used the phone 1.5h with wifi so nothing bad to say

[Q] help please: erratic battery levels/reboots

Although there are similar reports of battery issues, I haven't found anyone with the same issue. I have an SGS2 running 4.0.4 - all stock and although I'm on Orange, it's not an Orange handset. It's just over a year old.
Since being on 4.0.4, I've noticed the battery level drops when I switch it back on/reboot. It has been dropping by 20-30% but recently it's been dropping all the way to 1%. It has also taken to switching itself off with no warning (or shutdown) - I can only assume because it suddenly thinks the battery is at 0% despite what it was seconds beforehand.
As a typical example, it was charged to 100% (4200mV as shown via *#0228#). After a few hours standard use, it was around 60%. Then, seemingly when I'm doing something intensive like recording video or downloading something over a data connection, the screen goes off and I realise it's dead. I restart and the "battery critical" warning comes up - 1%. It dies again and I remove the battery for a minute, put it back, then power up. This time it says 9%. Then after a short while it dies again. So I connect the charger. After a couple of seconds, the battery charging indicator shows about a 1/3rd full. I switch on and the battery is now at 46%. Whatever the issue, reattaching the charger seems to rescue it - even if it's not back to the original level. The charge levels (in mV) seem to match the percentage.
This happened so much that a few weeks ago, it wouldn't even start and I had to wipe and reinstall everything. It does work now, but still crashes at least once a day. I'm not sure what else to do other than wait for Jelly Bean and hope that will miraculously fix the problem.
I have attempted "battery calibration" though it's a bit difficult - and I've read that it doesn't actually work anyway.
I am a noob - so please treat me like an idiot in case I've missed something obvious.
Thanks.
Dude, I believe it's time to buy a new battery.
1.Battery Calibration apps don't work(They don't do anythight good) Battery calibrates selfs...
2.I think that your battery is dead like my (Buy one it cheap)
3.And I think too that Insane gauge chip is very crazy...(You can reset it maybe helps... need flash Syiah and Get Stweaks)
I have the exact same problem, see this thread: http://forum.xda-developers.com/showthread.php?t=2062056
Tomorrow I will buy a new battery, I can tell you if this will help me out
Yup, battery calibration is a myth. Google already states that you do not need to reset your fuel gauge for ICS/JB devices. All battery parameters are automatically reset when it's 100% charge.

I've ordered a new battery which I should have later this week. Let's see if that does anything useful. In the meantime, I'm attaching some battery meter screenshots to illustrate the problem.
Thanks for your suggestions so far!

My battery went from 50% to 15% after a reboot.
The bizarre thing, though, was that I watched it increase from 15% to 20% charge even though it was not plugged in.
Weird...
