No matter how long my g tablet is plugged in,
it does not charged until the battery meter says 100%.
It always get charged upto 96%.
Is there anyway to fix this problem?
Is it something that can be fixed by clearing batterystat.bin?
If that so, can I do that using adb? Thank you.
khunny,
This is pretty common with the G-Tablets.
You can run it down all the way and then go into CWM and tell it to reset the battery stats.
But often as not that doesn't change much.
My personal advice (I have one that often does the same) is just ignore it. If it's 96%
you've got no problem and at less than 10% you better be thinking "charge."
Rev
Mine only charges up to 96% as well. Gonna try to reset it in CWM after it drains. Hopefully it works, cuz while having it only go to 96% isn't a huge deal its something I would like t be able to fix.
search is your friend
It is normal. Gtab treats 8.3V as 96%. In theory, 2cell li-ion battery 100% of charge is 8.4V. But, such battery does not like to be overcharged (it will shortened battery life).
mine did charge to 100 percent before installing vegan 5.1 supplement? Now it charges to 98 no matter how long i leave it plugged in? There has to be some way to alter the battyer stats to show 100 percent if it is??
Mine finally got to 100%
I had this tablet only for a week or so. I have installed Vegan 5.1.1. I noticed the battery only charged to 95% or 96%. I have drain the battery all the way, and then "Reset Battery Status" in CWM. But, it did not work the 1st time. Then, I drained it again. After the tablet shuts off automatically, I would push the power button to turn it on a few times to drain it more. Then, I reset the battery status in CWM, AND, I "Fixed File Permissions" right after the battery status reset. Then, reboot the device, and it reached 100%
Note: I drained the battery at work, tried to turned it back on about 3 times after it shuts itself off. After I got home, a few hours later, I turned it back on one more time, and the battery showed 2% and stayed on for quite a while. Not sure why that is. Hope this helps.
Not battery life.
Today i noticed my battery meter has been sticking, any way to fix that? It'll drop 20% upon reboot.
Today i noticed that my battery would spike up from 95% to 100% while charging and not go anywhere in between,. Is that normal? Battery calibration app kept going off early, and then as soon as it hit 100% i unplugged it without calibrating it, and it dropped to 99%. Happened twice in five minutes.
Also, instead of using clockwork recovery, i use Battery Calibration app to wipe my batt stats.
What mV should i be on?
One last thing, how do you bump charge? And is it really that unsafe?

I noticed this yesterday, I had my phone plugged in and it was at 94-95% and 2 minutes later it was at 100%.
To bump charge, once your phone is at 100%, unplug your phone power it down then replug it in. Once it shows the green LED meaning 100% charged boot your phone up and keep it plugged in. Might go back to being orange saying its not 100% yet so let it get to 100%. Unplug it and replug it back in a couple times until every time you plug it in it shows green for 100%.
I would think that it would be bad for the battery if you do this every day, but I can't give a definite answer for that. I use Battery Calibration to do that too, but between today and yesterday after I flashed over the new CDMA/LTE radio leak from the Radio thread my battery life hasn't been great. Considering going back to the stock radio.
I've noticed similar things on my bolt and even my dinc. To counteract this, I stopped looking at the battery % and got battery left instead. This app tells you how much longer your battery will last in hours rather than %. I no longer freak out about my battery life, %, or what others are getting; I've never been happier.

Sounds like a good idea especially for me lol. I noticed this morning that my phone was 56%, down from 74%. 18% drain over the time span of like 6-7 hours or so while I was sleeping. Not sure how good or bad that is, but for me it was just like wow.
You're being anal. Don't worry about it. Your phone is working fine. The battery level will appear to jump around a bit, especially when going on/off charger, or rebooting. Search around if you feel a need to know why.
So I charge my Galaxy S2 to full (or at least, it says it's full), unplug it, and it says it's only charged to 60%, or 43%, or something random. I plug it back in, and off it goes, starts charging again, this time usually up to the "proper" 100%.
On top of this, the battery drain is very fast (10-15% overnight)
So, believing it's the battery, I get a replacement. Same thing.
I then learn that the reason might be because I flashed Lite'ning ROM while not on full battery, and that it just needs a battery calibration.
Ok, so I do a battery calibration - I charge it to full, drain it to 0%, then charge again. Take it off the charger, plug it back in to make sure it's full and...what do you know, the battery meter shows it at about 20% It continues to charge for about 4-6 hours after this.
Help? Is my phone faulty, or am I just not doing the calibration correct? I don't think it was like this before I installed Lite'ning ROM. So I'm praying it's not the phone itself?
The only other thing I can think that it might be, is the fact that it's a UK Galaxy S2, but I'm using it in Japan with a Japanese charger. Though I don't think that's an issue.
Any help would be very much appreciated.... not only does my battery not charge to full in one go, but it has **** life afterwards
did you try removig battery stats from recovery mode?

Yeah, that's what I meant by "tried the battery calibration".
Charged to full, wiped battery stats from recovery, then rebooted.
Try using app battery monitor widget, and check battery is actually charging it to around 4200mV, and discharges to around 3500mV at approx 1%.
100% is not full, it will continue charging for quite a bit after to around 4200.
At least you will know that the high and low scale is correct, and can monitor in between.

So I charged it overnight via AC adapter (with the phone turned on), woke up, and the phone was at 4%!
Seriously, what the hell?
Phone was indeed reading close to 3500mV via Battery Monitor when it was almost empty
Any help?
Try charging via usb, much slower than ac though, then check again.
Don't drain battery to 0%, certain reports indicate not good for the battery, others say no worries. Try 1% so the phone doesn't turn off.
Although the huge jumps in battery level indicate a battery issue; If still no good, try a different ROM, and recalibrate. Also try in flight mode overnight and check results.

Thanks for the suggestions man, I appreciate it. My main concern is whether or not it is a problem with the phone itself - the place I bought it from has a ****ty returns policy and won't exchange it or anything. So I'm hoping like hell it is something I can fix myself (new battery, new charger, different rom, etc etc etc).
As I mentioned, I'm currently on the latest Lite'ning ROM with Ninphetamine kernal I believe. Just did a factory reset/data wipe via recovery mode, thinking it would get rid of lite'ning rom and the ninphetamine kernal, but upon rebooting the Lite'ning rom theme (blue lightning on the icons, etc) is still there.
Anyway, I have it charging on USB now, and I have ANOTHER battery coming tomorrow, along with a stand-alone wall charging unit (that charges just a battery on it's own, not connected to the phone). Maybe I should charge the new battery via that for 16 hours, then stick it in the phone, wipe the battery stats via recovery, and flash a new ROM (say, the new villainrom)?
Yeah, forgot about that also, I have two SGS2 (one in for repair), and each time new have let is charge overnight without turning on before first boot. Then discharge to approx 1% (do not let it die), then charge fully to 100% and approx 4200mV. Quickly clear battery stats with Battery Monitor Widget (menu / stats / SU permission, no need for recovery as you'll waste battery rebooting and get inaccurate reading) and immediately disconnect charging. A new batt stats file will be generated.
At least with this method you'll know your at a "true" 100%.
Also, it may take a number of charge cycles for full battery potential, but don't let it die.
I use Cognition straight "out of the box" with no issues.

Hopefully I can state this in a way that doesn't scream "I don't know how to use teh search!"
I calibrated my battery stats using the free app on the market after flashing darkside. My phone used to charge to 100% on the indicator (4200+ mV). Now, a couple of weeks later, it charges to the same 4200-and-up charge but the meter tops out at 92%. Two days ago, it was topping out at 94%.
I've re-calibrated using the app, draining it down and charging fully up. Same result, 92% max.
I've wiped battery stats using CWM immediately after charging fully (verifying the charge is above 4200 mV). Rebooted. Still at 92%. Actually, now it's reporting 90% with 4128 mV.
so if wiping stats is a "useless operation", what gives? How is it possible that this method apparently fixed other users' miscalibrated battery meters stuck down around 30-40%?
Try this:
1. Charge as much as it will charge
2. Turn it off and take out the battery
3. While the battery is still out, plug it in and wait for it to show the battery image with the question mark
4. Put the battery back in (do not turn on yet) and let it charge for an hour
5. After an hour, turn it on, unplug, and report back
Note: On step #4 when you put the battery back in it will probably only show like 5% or 10%, just ignore that and let it charge

Bump charging now. Will report back in an hour
.... all right, got impatient. Pulled it just now; 99% on 4158 mV. That's better. Many thanks!
IT REALLY WORKS.........Thanks so much!

in cm7, charges to 98% normally, but sometimes takes hours to reach 100%.
I hope i'm not hijacking this thread, but since we are talking about mV i thought this might be a good place to ask....
I've been having problems with my battery levels for a while, i've tried all the voodoo to try and fix it but i can't get anything consistent.
here is what i get....
i have battery calibration app installed, sometimes it will read 4200mV and be 20% charged. Other times it will read 100% charged at 3700mV, it's all over the place, and trying all the suggestions to fix the battery life don't seem to fix it.
another thing i have is it will discharge from 100% to 5% within an hour but my mV will be at 3900+, then it will sit at 5% for another 8+ hours then the phone shuts off, so i plug it in and it says 5%, i let it charge for a minute or two and it's at 20%, i turn it on and it shows that it's above 3700 or 3800mV.
so the phone thinks it needs 3700+ mV to run, but not always, sometimes it will go down below 3600mV and still run
A couple questions
1. can someone post their mV reading at 5%, i'm guessing it should be about 3300
2. what is the max mV that you have....is it above 4200mV (mine never is)
FYI information i've tried fastboot -w, cwm battery wipe, deleting the battery stats file manually, even formatted /system and other file systems to make sure it was fresh

Ok,
I did this and my battery starts off at 100% and all appears to be fine. The next time I charge, it only shows 83% and it is reading 4200mV which should be a full charge. Do I have to do this each time? Is there any other solution? I am running CM7 stable and the battery is an aftermarket one. Could this be the issue? Thanks in advance all.

One trick I've found is unplugging the micro-USB and plugging it back in immediately. When I do this the 4200mV usually drops to the low 4100 range and the % continues to increase.
Only caveat is you'll have to keep doing this until it reaches 100. It takes a while since it seems to get re-stuck at every 1-2% intereval. A pain, but it's a work around from having to pull the battery. :silly:
I have the same issue too but DO I ALWAYS HAVE TO DO THIS METHODS? My battery level drops day by day (becomes %92 max) from %100.
I'd had the issues you explain for AGES.
I'd heard that buying a new battery wouldn't help. But I bought a new, official battery off eBay and I've not had the issue since. That was a couple of months ago now... not saying it will definitely work but at worst you have a spare battery...
What works for me... Charge up as much as possible, then use root explorer and go to data/battd/ and delete everything except the file "uid" then reboot... Should be good to go...
Hope this helps!

This definitely worked for me. I was having repeated issues that full charge/drain calibrations didn't fix. This did.
I had the same issues with charging it ,but i foudn out that the only failproof method of chargin it by using the oem ac adapter and the oem usb cable if you dont have the cable the nokia cables shoud do the trick but the samsung one does not work i dnno exactly why but i tested it myself.

For the past few days my battery has been charging to a max of 92%, whether or not I try unplugging the battery, leaving the phone on the charger, wiping battery stats, and doing all that I can to try to reset the battery stats.
Anyone have any idea?
UPDATE: My phone is still not charging past 92%, no matter how long I leave it on, or what I try to do to fix it. 4167mv max
I have a similar issue, it's been like that for a long time for me. What ROM/kernel are you running? It might fix it to completely drain it, charge it powered off, reinstall ROM/kernels when it is completely charged and reset battery.

drain it until it shuts off and then charge it all the way to 100%.
I too was having this issue after going from cm7 week 5, to week 8. I did what others were recommending and charged to what showed 4200mv, pulled the battery while still plugged in, put battery back in then after it showed 5%, turned it back on and Viola, 100% battery. Try it.
its most effective if you know your battery is fully charged, power it down, pull the battery, while the battery is pulled plug it into the power adapter, it will act like its starting to charge, but then instead of having a percentage, it will have a question mark. pull the power, put the battery back in, turn on, wipe battery stats in recovery and run with it...

I just started having this issue and cant wait to try it thanks for the suggestions.
when this happend on mine all i did was keep using it and it fixed itself. i ran it down maybe to 20% before I got to charge it again and it slowly creeped back up to 100%. took about a week.
I've had the problem, and have run the solution more times that I can count. But nothing ever fixes it permanently. Everytime I run the battery low, the levels get all screwy again. Maybe my phone is just worse than everyone else's, but I had to just give up on it. Would love a permanent solution, but so long as I'm running this ROM (CM7), I doubt I'll ever find one.

I'm in the same situation as you are... I had this problem for a long time now (Guess it has something to do with excessive flashing...) and no matter what kind of solution I do (Wipe battery stats via recovery, re-calibrate the battery, pull the battery out while charging and replugging it) it returns after a day or two.
I want to check if it has something to do with the battery or the device, and if I will remember to do so, I will plug my spare battery for several day's run, but that is subjected to me leaving the comfort of my usual laziness....
Would love if there was a permanent solution as well, thou I doubt that too....
I've had the same problem on a number of different roms and at different times. I find that instead of mucking around wiping stats etc, it has always come good eventually for me.

Didn't really understand what you meant, did the battery percentage fixed by itself and gave you 100% at full charge on one day? out of the blue?
Or did you just got used to have less then 100% battery display?

First let the battery completely drain and the phone shut down by it self. Second step is to pull out the battery and leave it out for 10min, after that take a plastic bag and put the battery in it and place it in the freezer for 15min. after this palce the battery again in the mobile. make sure there is no any moisture on the battery. Then charge the phone without power on till 100%.
By following these steps this will made your battery to charge fully and more talk time

Um correct me if I'm wrong anyone, but doesn't cold kill the battery and shorten its life? I remember my mom always putting new batteries in the fridge and them only lasting a couple days compared to the ones left out that lasted a month or so with same use.

Haha, I got a good laugh out of this one -- you've got to be joking.
I've had this problem for a quite a while now with the Atrix and two different batteries. I've tried dozens of combination of resetting the battery stats, running the battery completely down, and powering up without the battery and hot swapping it in. The hot swap definitely allows me to finally recharge to 100%, but once I run it down again, the problem returns. I've learned to just live with the less than 100% reading -- battery still seems to last a full 24 hours for me.

That trick hasn't worked since nicad batteries in the 90s, and is a really bad idea with our Li-PO.
Drain the battery till the phone shuts off, charge back up while the phone is off.
If it still doesn't get to 100%, boot into CWM, wipe battery stats and power off the phone to let it charge again.
^^ I know it works because I've done this like 2 days ago, and many times before that.
I have had this issue as well for a very long time. I've tried the pull out, question mark, 5% thing and it usually only works for one cycle, then the next only goes to 97%, then the next to 93%, then 90%, and it continually goes down until I have to do it again. Hopefully a permanent fix can be found soon. I've tried clearing battery stats, draining it to 0%, then charging it fully. I've tried everything. As far as I'm concerned, there's no fix as of right now.

★ATTENTION! I FOUND THE FIX!★
Turn phone off and plug it in to a wall charger. Charge it until your notification light turns green, quickly tap the power button to check battery level. (Usually shows 90%) If the notification light turns on, but the battery indicator is not at 100%, unplug phone, take out battery and put it back in. Now plug your phone. It should be 100% now. For the final fix: go into "Android Recovery" and select "Mounts". Mount Your SD card and Emmc. Finally wipe battery stats. Reboot phone.
This method worked for me. I am 100% sure this is the fix for this problem. This has to be done every time you flash a new rom or when your phone freezes and you screw up calibration by pulling the battery while it is still on. BTW, this is my first post so don't be mean to me!
