Try to do a full recharge cycle with the phone turned off, then wipe battery stats and wait for some recharge cycles, i will probably get better..
Cheers
i'll check and tell u..thanks in advance

Hey i flashed my device with the battery at around 80%.
after the flash it was 100%...
so this means i just lost 20% of my capacity? how do i fix this?

I don't believe you have lost capacity. It's only your gauge that's slightly altered. If you recharge your device fully(and about an extra 30min) you should have the regular capacity
How could going from 80% to 100% equate to a lost ???
it's posible that you'd gained the extra charges while the flashing process was going on ( because it was plugged in ?? ) ... if it wasn't ... no idea why

If i understand the post correctly they are equating am 80% to 100% a loss for 2 reasons:
1. because he would have lost charge while flashing due to the massive battery drain.
2. because now he is stating that his 100% is really only 80%
but i would probably just leave it charge overnight and you should be fine, the gauge just sounds to be off, it shouldnt be a true loss (unless the battery is bad)
Is there any other way to sync the battery with the device? I been trying a full discharge then charge.
I am using a mugen extended 3000mah battery and at 15% 10% and 1% it will stay there for some time before it starts to go down or turn off completely if it is reaches less than 1%.
I don't think you've lost capacity.
I believe you just did a quick check before flashing (and it was already charging before you started right?), and the battery gauge wasn't updated. I had this a couple of times while recharging. I take a quick look and think "this is gonna take another half hour". Five minutes latter I check and the charge led is green again.
Sometimes the battery metter lags a bit, you have to check it again to be sure when charging.
At least it happens to me.

a few cycles of full charge and discharge should put the battery meter in check...

Alrighty. I have done three so far. It has gotten better then the first time I got it. But its not perfect.
is it safe to discharge it to 0% so that it will shutdown? or what?
Hello everybody,
to begin with i must say that my phone's battery used to take 2 to 3 hours max to charge from wall charger but now since i flashed the ROM and it has been acting so weird when charging. I have monitored the charging time and found that
after 1hr the battery goes to 50 %
after 3 hrs its up to 70%
after 5 hrs its up to 89%
then after being on charge for 6 hrs its fully charged !!!
p.s the battery lasts the normal time it used to.
so what's going wrong here?
your help is much appreciated!
You're using the same charger right? I believe aftermarket chargers are slower and suck!

Yes its the same original charger!!
The only suggestion I have now is to double check if it's really because of the rom?
Try using another rom for a day or so and see if it also takes you that long to recharge. Don't restore apps or anything yet either! (could be an app causing it, however that's unlikely) Mine only takes long to charge if I'm using too much stuff while charging it.
It is normal. Charge voltage is lowered when reaching 70% (or 80%, you can check it at battery stats) and then even lower when almost full until it is really 100%, not to harm the battery pack. Your previous cycles only semmed faster, the more you use your phone the better your battery stats will be.
If you wiped battery stats before, it could be another reason for strange figures.
Most importantly, if you want to have a good battery life on the long run, dont fully discharge/charge it.
hello,
I started charging my tab, it got charged till 99% and then i kept on charging it but it didnt went above 99% so i thought may be its because i am using the cell. So i switched it off and kept on charging , The battry icon was charging towards the end part (like the last 10% is getting charged) but in brownish yellow collor (sort of dark orange color) i kept it for charging in this way for like an hour.. Still when i turned on the tab, its 99%. Why so??
I havent rooted it yet! its total stock..
Bought it just 5 days ago..
About half the time, my tab will only go to 99%. Since it's only1% I've never given much thought to it, but I do experience the same problem from time to time.

after reaching to 99%. How long does your tab works??? Are you using p3100 too??

I'm using a p3113. I've never noticed much difference in how long it lasts. Most days, my tablet will last all day whether it charges to 99% or 100%. You really shouldn't see any difference to speak of between a 100% charge and a 99% charge. I personally think it's an overcharge feature to keep it from overcharging. I've actually seen it jump from 100% to 99% one time. If that's the case, then it's a good thing. You could try to bump charge it like I've done to cellphones that won't fully charge. I really wouldn't recommend it since 1% is practically nothing.
Charge it up (powered on) until it's finished.
Unplug it, and turn it off
Plug it back in to charge (still powered off) again, until it says it's finished.It will continue to charge now.
Now unplug it and turn it back on.
Plug the charger back in (powered on) and charge until it says it's finished.
Keep doing this until when you have it powered on, it should say 100%.

The battery charging end is defined with two parmeters: the battery voltage reach a voltage close to 4.2 V and the battery charging current gets under 200mA ( a value I have estimated on my 5110 model) .
If for some reasons the residual current do not get under this limit value ( # 200mA) while the maximum battery voltage is reached , the state of charge stay screened at 99% !!!!!
The 4.2V battery voltage is a safety limit that a Li-Ion battery should not exceed. Most often the battery voltage is stabilized close to this value at the last stage of the charging cycle and the internal charging progam decide that the charging cycle is finished when the battery current gets under a predifined value.
I have given some examples of charging cycles of different smartphones in my blog : http://78michel.unblog.fr (sorry most examples are in french).

So I should stop charging when its 99%?
How many hours does ur tab lasts after charging 99% ?? Cuz mine doesnt lasts even 4 hours .. never charged 99% (just bought it somedays ago) did it yest , its working well now .
Screen takes too much battery ,.. ny way arround it to have better batery life? i saw CM10.1 but it has probs with gsm device so I m not using it ..

hello friend me too got gtab2 few days back.couple of days back i left charger connected full night and next day i saw on screen "battery fully charged unplug charger"my tab last full day when i return home its around 30%.abt ur battery life i doubt may be some apps are consuming or may be continue wifi use?if this is not issue then u must report this problem to cc coz 4 hrs backup is very less

I think it is better for the battery life to stop charging if the state of charge level stay on 99%, because the charging current is maintained continuously in the battery and I think this is not so good for the battery life.
You can check the battery current in the battery with diffrents battery monitoring systems. I use Battery Monitor Widget. This is very convenient app. to analyse the charging cycle and the draining of the battery.
Analysis of my 5110 here: http://78michel.unblog.fr/samsung-galaxy-tab-2-10-1-tests/
The screen of these tablets is the most current draining component. At max screen brigthness the battery life is a less than 6 hours on my 5110. The brightness should be setted as low as possible to improve battery life, other componenet such as WiFi... GPS have very low impact on the battery life.....
Hey I am facing severe battery drainage problem...
The phone is been charged very very slowly when its on and drains very very quickly...
it charges a little fast when switched off but its still slow as compared to normal android phone...
help...
I charged around 50% in off phone and after in on the phone and the battery almost 0% in just 15 min...

First check your battery whether it is swollen or not..
If not try to calibrate your battery.. Remeber calibrate doesnt increase battery life it will rectify your battery stats.. I think your battery stat is showing wrong info..
Let the battery drain off completely charge until 100 dont take out while it is charging.. Calibrate and restart you phone..

I think you are right that my battery stats are not proper... because I just restarted my phone and my. battery gone to 73% from 23%....!!
and my battery is not swollen...
But can u tell me the calibration steps?

Simply install battery calibration app from play store i think after search 1st app will b the one.. Install it.. Instructions are given in the app just after install open it..
The instructions are simple anyway..
I just got a battery from etradesupply and now im having some issues with charging and fast drain. The battery will charge like normal up to 100% but if i power the phone off it will start charging for another 15 mins before full. After it's full and i power up it will show 85-90%. Ive done this cycle about 5 times. The battery also drains the first 10% in about 10mins after i unplug it then it will slow down. Just strange that even with these problems the battery life is about the same if not a bit better than the old battery. Im rooted running 5.0.1. I might try a fresh factory install when i have time. Anyone have suggestions before i try that?
bump...any ideas?

I'd say try to wipe everything on your device and flash the stock factory image first and see how it goes to rule out a software issue. If it still does not help then should be the battery.

When the battery first reaches 100% it's actually not done charging yet, it takes about 30mins afterwards before the juice stops flowing. If you unplug during that time it is normal for the battery to drop to show you the true charge level. Could that be what's happening here?
Try keeping it plugged in over night and then the next day it shouldn't drop by more then 1 or 2% (trickle charge kicks in around there).
