Hi All,
I have searched briefly but I cannot find this exact problem...
I have the S3 and I have had it since the begining of December 2012...I rooted and installed JB the first day I got it SO I cannot tell if it was me or if the phone was faulty.....but I have reverted back to Stock and the problem is still there.
Basically the phone does the following and it's starting to get to me.
*The phone charges to 100% but then it stays there untill I reboot and only then can i see the real battery percentage, it annoys me as I never really know what my battery is sitting at without rebooting.
*As the battery charge drops the phone will make a noise as if its connected to a charger and it will say its charging on the screen but the percentage still drops and this also won't go away until I reboot the phone.
I have tried the following and no success.
*went back to factory rom via KIES.
*fully charged the phone and then ran battery calibrator and removed the battery.bin file.
*inside clockworkmod I have resetted the battery stats.
*discharged batter completely....made sure that phone cannot even display the battery icon when attempting to switch it on.
*tried several roms
*tried several kernels *currently on YANK's 3.1 Aroma kernel.* (which is awesome by the way)
*left the battery outside the phone for half a day to see if that helps.
How come a simple reboot fixes the problem....which is why I'm logically thinking it's software related.... but I could be wrong.
Does the battery itself have a sensor inside that's reporting the incorrect information to the phone? aka charging when it's not?
Are there any other methods you guys can perhaps reccomend as I'm starting to pull my hear out
Does the battery itself have a sensor inside
Yes.
Try the usual answer and recalibrate your battery/ wipe battery stats . =Does not help .
Other option try different battery .

Been using the g tab since December and have always been impressed by its battery life. Only issue was the battery meter never seems to reflect the true battery level. I had times when it just shut off without warning with the battery meter at 100% while other times, it drained rapidly to 0% within 20 minutes.
I know the general fix is to delete battery stats with recovery (which i have been doing frequently) but that still doesn't quite solve the problem. As such, i decided to test the exact battery life of the tablet. I am quite shocked at just how good it is o.0.
I've had a (1hr 17 mins) video looping with wifi on and connected for exactly 9 hours now as i am typing this. The battery meter still reads 100% but i think it will turn off/drain rapidly soon.
I am on TNT Lite 3.1.4 btw (old but gold).
Update: Tablet just shut off after 10h and 56 minutes on video loop + wifi. Video was stored on tablet memory.
Issue: Battery meter never drained and was 100% till death (i plugged in and rebooted and it read 100%). I had just wiped battery stats before doing this experimental run. Any suggestions to deal with the battery meter issue?
I had a similar problem with another tablet after wiping the battery stats and still don't know if that was the issue or not. From my recollection, you were supposed to discharge the tablet completely and then delete the battery stats (or was it charge it completely?). Is it possible you deleted it in the wrong state, so it thinks an empty battery is full? I always wonder if I might find a similar fix for the other tablet or if the charging hardware simply failed (not a gTablet -- a flytouch2 type device).

From what I've read about calibrating the battery on other devices (specifically in the EVO forums), you're supposed to charge it until it's full, immediately wipe the battery stats, run it until it's dead without turning it off at any point, then charge it until it's full with the device off. Turn the device on and it should be properly calibrated. I'm not sure if this will fix your problem, but it's worth a try.
If that doesn't work, you could try flashing a different ROM and see if the problem persists (backup everything in clockworkmod first, so you don't lose anything if you want to go back to that ROM). If the problem goes away, it's probably an issue with TNT Lite 3.1.4. If the problem persists, it's probably an issue specific to your gTab.
Thanks guys. Ill give it a go.

I've been having an issue where my battery show that it is discharging but then it abruptly shuts down when it hits ~50%. No warning of low battery voltage.
I'll try this calibration and report back with results.
Update...8 months on.
My G tablet is now running Flashback 10.3 (finally HC is stable enough).
Battery still does not reflect drain, stuck at 100% every time. (i've been told its a kernel issue)
On Flashback 10.3: Looping a youtube video (1hr 14 mins) with HD on, sound off, wifi on, brightness set to automatic in a dark room. Tablet died after 9hrs 21mins.
This is 1.5 hours shorter than the result i obtained when i looped a internal storage video, wifi on, brightness automatic, sound off 8 months back on TNT 3.1.4 (froyo).
I'm pretty impressed given the 3700mAh in our device (compared to most 5000mAh tablets). Anyone done any tests? Do share.
I have a problem with the battery on my SK17i (MFG date 11W30).
My phone is stock - Locked Bootloader, stock launcher and so on.
The problem I have is that when the battery level comes to about 20%, it jumps from 20 to 15 and then to 1% and shuts down, this in a timeframe of about 5 minutes.
Anyone had a similar problem and/or a solution to this problem??
almost same, battery callibration not works... full phone reset with 100% seems to work, but note - phone shold be charget from android, not offlined!!! in offline mode hardware seems to use another voltage for chagre and after reseting or callibrating you would have some hours of 100% charge indicator... any way i'm sick from that problem... with new .58 firmware my best result is 10%... then drop to 1%... no callibration or reset helps probably problem in battery hardware or battery driver software.
And one last thing I've noticed: if you use phone in lite mode, when it stays in idle for a long time, then drops comes often... but in case if you stress your phone with some apps and calls then drops are not so often, and battery goes smooth from 100 to 1... so probably main problem in battery itself.
ps. sorry for misstakes, text was writed from phone.
still no solution for the battery drain?
Did somebody figure out if it is based on the kernel itself (I myself have the latest firmware, but still no better battery life, and yes everything off except cellphone coverage) or some program running in the back that isn't visible?
solved!
found solution for avoid battery drop from 20-30 to 1% percent. (personal data would be lost)
1) discharge phone to 0% or 1% (this is !!!important!!!, because offline charge should be full, I spend several weeks in (_!_)-pain before catch a moment)
2) turn it off
3) wait for 2 hours (probably 1 hour would be enough too, phone charges to 100% dam fast , but to be sure lets say it would be 2 hours)
4) do not remove charge cable (this is voodoo thing, not sure if it is important), boot up phone
5) go to "Settings -> Privacy -> Factory Reset" (not sure that it called exact, but be sure that all data would be erased)
6) phone would start to erase data and go to reboot, in chat moment remove charge cable (this is voodoo thing too, not sure if it is important)
7) after boot up battery should be ok!
as I understand problem in locked firmware, and if your bootloader is locked, then any battery calibration software with root access would be loosed during reboot, so you need "SE native" method
battery drain
Hi.I have had this same problem whit the battery,the reason for this was that the battery was not format properly during first view chargings.In result I just clear the battery cache for couple of times every time the baterry was draind and recharge it again.My battery show every % now,so that was the resolusion.I hope you guys anderstand my english.
I hope hope you guys can help me with my battery life. And yes it's another battery life topic!
The thing is, I've got a lot of problems with my battery:
My battery only lasts 10-12 hours when I barely use it. This is a lot shorter when I actually want to use my phone
In the top left corner it always says my battery is full even though it's not
When charging battery, the percentage goes from 70-75% to 100% instantly
The battery stats are incomplete. Since unplugging this morning the stats say it's on battery for only 9 min.
When looking at the app betterbatterystats the data is incomplete aswell.
When unplugging the phone the battery percentage stays on 100% for 1,5-2 hours until it counts down, fast. In Battery Monitor I can see it goes from 4982 mV to 4181 instantly
The things I've tried to fix it.
Setting brightness to lowest level
Reset to factory settings
Hardreset
Disabling Sync
Clearing cache
Clearing Dalvik cache
Clearing battery stats
Calibrate battery
Stock kernel with Lite'ning ROM 6.1
Speedmod T41 Kernel with Lite'ning ROM 6.1
Disabling HSPA
The strange thing is, these problems started occuring around 4-5 weeks ago. I first thought I installed some app which was killing my battery but reseting to factory default and uninstalling all app's didn't help one bit. Are there any more solutions I can try solving it myself or is it time to send the phone to Samsung (and thus having to do without the SG for 2-3 weeks)? Hope someone can help me with this.
Current specs:
Android version 2.3.4
Baseband version I9100XXKH3
Kernel version 2.6.35.7 [email protected]
Build number Lite'ning Rom v6.1 XXKH3

Possible faulty battery .

Reset Battery Stats .
When charging battery, the percentage goes from 70-75% to 100% instantly
Faulty Battery/charger
The battery stats are incomplete. Since unplugging this morning the stats say it's on battery for only 9 min.
This is more like hardware/charger/battery problem .

Currently your warranty is void with rooted phone and or custom rom Samsung may not accept a warranty return or may charge .
Suggest flash stock rom or your original rom clear custom rom counter with USB jig .

It sucks but I already thought that was the last option. Thanks for the info!
I recently dropped my S2 into water for a few seconds and following a week of drying out I turned it on to find that everything is working fine. The only problem I have is that the phone thinks it is at 100% charge after being plugged in for a few seconds. On the first charge I left it plugged in whilst showing 100% and overnight it managed to charge fully so that the phone worked for a full day.
Today however, it reaches 100% (after a few seconds) and seems to stop charging any further. I can use the phone whilst it is plugged in but as soon as I unplug it shuts down due to no power.
Is there a way to reset the battery stats or fix this? I'm currently running 2.3.4 stock.
Thanks in advance,
Chris
Reset battery stats .
As you dont know the basics try Battery Calibration from the market .

That requires root access... is there no way to address this without deviating from official firmware?
Try pull out the battery and put it in the hot water cupboard overnight (or blow dry it, but not too hot - it is a battery afterall), then try it again. Could be related to the calibration chip on the battery...
Battery calibration
It has been mentioned in several XDA forums that the SGS2 has a power supervisor chip that manages calibration automatically and doesn't need battery cycling.
You have probably sustained damage to your phone. It wont cost much to try a new battery though but it is a long shot.
Regards,
John.
I'm guessing it's a hardware fault with the charging circuit. I don't suppose anyone can recommend a good repair shop in the UK?
Hi, I am sorry I am using your thread to post a personal question.
I would recommend you to try a different battery though.
The problem I have is similar, but not the same.
When the phone sounds that it has full charged, I unpluged it and it immeadiately changes from 100% to 99% or 98%. After that it uncharges as normal.
What could be the reason?
I calibrated it with the battery calibrator. Also took out the battery after full charge and plug it back on. With no results.
What could I do?

You could have searched and read all the posts that say this is normal behaviour .

For anyone who's interested, I've managed to fix the problem by doing a full factory reset. To do this I powered up the phone into recovery mode (start whilst holding power, home and volume up) and performed both factory reset and and cleared the cache. Now appears to working fine.
Thanks for all the suggestions.
I got my motherboard changed a few days ago by samsung. Now i am facing a problem with my battery stats. My phone shows only 15% battery even if it is fully charged [Shows 100% after fully charged, but as soon as I remove the charger it again shows 15%] and when i use my phone it drains normally but problem is that after decreasing battery by 15% it automatically switch off.
When I restart the phone, it again shows 15% battery. so this cycle keeps going on till the battery fully drains.
This is the weirdest problem I have seen.
So any one who can help me please give your valuable time to resolve this type of problem.
Thank you.
P.S. I've tried factory reset, Battery calibration, and even flashed the stock rom again via odin.

The problem is with the board, you cant always assure the quality of the board the fix and its compatibility, if u are under warranty, service centre is the best option, first report this issue to samsung and then directly go to service centre and talk with the centre manager, not the mudheads on the reception.
