has anyone else suffered from this this is the 3rd time this has happend to me in 2 weeks i leave my phone charging overnight then take it off when i go to work so its at 100% charged then the battery has been draining really quickly this happend to me on tuesday and again today on tuesday it was at 20% at 11:30 am i take it off charge at 8:00 am and today the battery is already below 50% and its only been 2 hours since i took it off charge keep in mind i hardly use my phone at work and the days i do use it more than usual i still go honme with a battery level of around 50% when im off work wondering what can be causing this or do i have a faulty battery??
You got something killing your battery way too fast. Take a look at what you have downloaded/installed. Try wiping it clean and install everything back, one at a time to find the problem. I'm using Freeza's ROM and kernel, getting a full day of moderate usage and usually ending up around 50-60% by bedtime.
You in a bad coverage area?

Newbie here - I have a stock G Tablet.
Have added many apps and also Flash and it is working great.
My one concern is that however long I charge the unit,
I can't get the battery indicater to go above 93%.
Is anyone else experiencing this ?
hello there,
yes i am having the same problem. no matter how long, mine can't get past the 95% mark. clockwork mod + tnt 2.2
ideas on how to fix this, anyone?
regards
Try to recharge with the device powered off, and let it charge for at least half an hour after the light turns green.
I've left it plugged in a good 2 to 3 hours after the green light came on.
It still only reaches 93%.
Is it a bad battery, bad charger, etc.,
Any thoughts... anyone ?

Do a full cycle, all the way dead and then charge as stated for about 30 minutes after the green light comes on. It could be just a calibration problem. How long is the battery lasting for you?
I use it for short periods throughout a day, so it is difficult to gauge an accurate time.
A rough guess would be approximately 6+ hours.
I always thought it wasn't good to totally drain this type of battery ?

I think this is a LiPo battery - if so, then its is OK to let it drain all the way - just don't do it too often. You should *always* do two full discharge/recharge cycles on any Lithium-based battery as soon as you purchase it, and again about every month or two.
For removable Lithium-based batteries (i.e. *not* for gtab!), if you aren't going to use the battery for, say, more than a week, the best thing to do is to discharge it to about 50% and then put it in the refrigerator. When you are going to start using it again, let it warm to room temperature for at least a few hours to a day (depending on how big it is), *then* put it on the charger. Absolutely do not charge the battery cold as the thermal shock could damage the battery.
The initial discharge/recharge cycles "primes the pump" so that you get the maximum capacity out of the battery (who knows how long the battery has been 'sitting on the shelf'), and the ongoing discharge/recharge cycles keeps the battery at its maximum capacity *and* allows the calibration electronics more accurately track the slow decline of the battery's capacity.
BTW, my gtab's battery lasted on-and-off for almost 2 1/2 days. That was 'sleeping' it at night (*not* turning it off!) and using it on-and-off wifi/surfing/playing AB during the day. I must say, the gtab's battery life is phenomenal!

Thanks. Tried the full discharge and then full charge with the gtab turned off, left for about an hour after the green indicator, but still stuck at 95%. Even deleted the batterystats.bin file. no change. must i do two cycles of full discharge and charge?
I'm having similar issues. I powered off my gtab overnight and let it charge for 8-9 hours and I have not been able to get the battery to say 100%. I'm going to leave it on all day and let it discharge completely and try again tonight.
Drained battery and left it charging overnight and while I was at work (15+ hours) and its still at 95%. I wonder if I should exchange it now.... I'll give it another week....
If you do two full discharge/recharge cycles and the battery is still not showing 100%, then I would take it back. Either it is the battery or the battery calibration electronics that isn't working (my bet would be the battery). Furthermore, since the battery is "not removable", its just not worth keeping it and taking the chance.
If the battery had been removable, then Viewsonic could have just sent you a new battery instead of having a whole gtab come back....
(Note for Viewsonic - this is where removable batteries are superior to non-removable!)

Before you return it check the actual battery life. If it turns out that it's just a calibration issue and if your happy with everything else, perhaps you should keep it.
Read the thread about my battery test...
mine is different... I can charge up to 100%, and keep using it for few hours at night, put it to sleep, then I wake up in the morning and find the battery completely drained... any1 has the similar issues??

You can try going to settings/applications/running services and turn off all non-essential services before putting it to sleep.
Mine doesn't get above 96%, will have to try the suggestions here but overall I'm still very happy with battery life of the 96%...
thanks, i'll definitely try that... but I don't think I have too much installed or services running since I flashed it with the new ROM.
have you guys notice your battery temperature? i got 2 gtab but both operating at different temperature 1 at 23-24 other is around 31?
My battery life seems pretty good even though it doesn't go higher than 95-96%. I saw in another thread to try resetting battery statistics in clockwork recovery to see if that will fix the battery display problems. I'm going to try that next.
I've got the Malata Zpad (SMB-1002-3G) and mine now wont go over 91% (happened on the 3rd day). It used to charge to 100% no problem for the first two days.
I did a recovery (format) when you press the power and volume up button, but that didn't seem to do anything (other than wipe all my settings and put it back to original factory settings of course)
I'm pretty sure the battery is fine, and lasts just as long, but it would be good to be able to reset the battery status.
PS: My Zpad is not rooted or anything. It's pretty much standard (just running Launcher Pro).

Do you have Clockwork installed by chance? If you do you can charge the battery all the way up and then go into clockwork and reset the battery stats.
Might help...
Just received my set today, and the battery indicator was half full when I put it on first charge
Finished to full within 1.5 hours, and I used it to surf the net for about.. 5 minutes? The battery dropped to 86%
Is this normal?
Android OS usage was 6% though... no sign of the battery drain bug.. Yet!
That happens to me too. The first 10% seems to drop real quick

On your first charge? How about subsequent charges?
I did not have a chance to load test the battery... Because of the stupid camera defect, it is now in the service centre...
No its not normal by any standards .
jje
Surely it'll get better on subsequent charges?
Does leaving GPS Satelites 'on' have anything to do with it even if Google maps is not on?
I'd give it at least a few days of normal use to see how it goes. I've had mine for a couple of weeks and the battery life has definitely gotten better. Now I easily get a full day out of it and have 20 - 40% charge left by the time I plug it in at night depending on usage.
give it two or three weeks and you should notice significantly better battery life. mine certainly improved.
So I had my GS2 fully charged last night. At about 415am I played Game Dev Story for about 30mins and went to bed. I wake up this morning at around 1030 and find my phone completely dead. Obviously this freaks me out since I just got my phone and it should not be going from 100% -> 0% in 5 hours of being idle. Now maybe I didn't turn Game Dev off properly and it was running in the background? I don't know. I got this phone last Monday and this is the fastest it has died. (Even setting this one aside, I'm extremely disappointed in the battery life). Also, I plug it in to charge after I found it dead this morning and went back to sleep. Wake up 2 hours later at 12pm and see its only charged to about 40% and the phone is really hot.
Are these normal for the GS2? It didnt get hot during previous charges (atleast I didn't notice it getting hot). Also what is the average battery life for the S2 and how long does it usually take to charge from 0-100? For some reason I feel like there is something wrong with mine and I should be exchanging it but unfortunately I did root it so undoing the whole process will take some time since I'm still waiting for the jigg.
Normal charge time from zero to full 3-4 Hours via stock charger .
Excessive battery drain multiple posts on the problem .

I don't think anything is wrong with the battery. You can see the battery usage graph, and post if needed. And the device takes around 3 hrs 15 mins from 0 to 100% charge with AC charger.
Regards.
Ive been having a weird battery issue. my battery gauge will say its at 15% or whatever it says at the time. ill plug it in and like 10 minutes later it will say 100% battery is fully charged. Obviously its not 100%, even when I charge it overnight, when I unplug it itll be stuck at 100% for like 2 hours then all the sudden drop to like 85%. im lucky if my battery lasts 12 hours now , same thing has happened on different roms. Do I need a new battery?

I'd try a different ROM/Kernel, see if that makes any difference (after clearing batterystats in CWM).
If that wouldn't help, I'd say battery is ze dead.

tried differents and kernels, and wiped battery stats guess my battery is done
try "battery calibration" app. it helps me a lot, and keep my phone running longer. i can last almost a day with medium use.
i have also tested with on screen non-stop (wifi + online game that require wifi, brightness roughly around 30%, medium volume, with whatsapp and talkbox in between), in conclusion, i can run for 4hours plus straight with sufficient battery left. i never push it through, i think i can go for 5 hours if i want to.
battery calibration app can be found in play google store
Worst battery life evah!
Im having issue with my battery as well, I plug it in a electric outlet for about an hour last night and when i saw the charge, it was only like 49%!!!!
And today, before my meeting it was like 22%, after an hour of meeting, BOOM! EMPTY BATT! What I only did was surf and checked my calendar!
It charge slow! And its draining fast!
something happened to my battery before last month, when i charge my fone it says 88% then suddenly after few mins 1 or 2 it become fully charge,but when i unplug my charger it comes back to 88% again, i tried some apps like battery calibration and also i'm wiping the battery stats in cwm everytime i flashed a new rom and it helps my battery charge in normal and accurate level...i'm using also cpu spy to checked if my fone is going to a deep sleep. now my battery lasts for 1day 11hrs with light usage. but for heavy usage i've got 40% after 4hrs of continious hd gaming.
Hey guys,
I have had my Galaxy S2 for over a year now. I have not always had great battery life but I blame that on my providers ****ty 3G connection.
My longest battery life I had on Hydra h2o ICS rom and that was about 2 days with 2.5h screen time. Those were the good old days.
Now I'm on Vanilla RB with the DorimanX kernel and am getting a little concerned if my battery could be failing me.
I have tried for some time now to get stable, good battery life on the JB ROMs and it doesn't seem to be working. This is my case:
I charge my phone at night and use it over the day. The past weeks my phone has really been heating up and the battery is draining to near-zero levels within 2 hours of screentime. For instance I was playing a game the other day for about an hour on and off and lost 70% of my battery. The thing is that when the battery drains this quickly it always seems to slowly increase as the day goes by and if this happens, the phone can hang for an hour or two on the last 2%.
This I find really strange and have tried numerous times recalibrating the battery and doing cycles and everything I have thought of. I don't have any strange wakelocks that can explain this drainage.
For instance my phone completely died on me this morning after rebooting it at 50% and it booted up with 1% left. I then took the battery out and waited a couple of minutes. In the process I checked the battery out and it smelled strange. I also thought i noticed a slight bulge on one of the flat sides of it. When I popped it back in and booted my phone it was at 13% and slowly increased to 22% before starting to discharge again.
What I'm wondering is if my battery is broken and I should buy a new one of eBay?
edit: Right now I was charging it and rebooted. It went from 22% to 63%. Isn't this just a bit strange?
If you detect a slight bugle one side of the battery.
It means it is time to change the battery before it burst.
The battery is not hold a proper charge or discharge it properly, itr could be one of the filaments maybe damaged in the bulging area.
Okay, is there any aftermarket battery that is better than the stock Samsung one?
I also have the same problem after flashing on stock ROM. Solved with app "battery repair". Honestly it was not original (replacement) battery, but it still works well.

I presume you've done a battery calibration in between roms

Yes, multiple calibration attempts.
But it's the bulge on the battery that has me concerned. It´s even ath the point where my back cover can't hold back anymore and sometimes comes loose where the battery is bulging.
One thing I'm noticing is that in AnTuTu Tester it shows the battery at higher voltages than the 3.7V on the back of the battery. So far I've noticed this go as high as 4.2V.
Is this something that is not ok? If not, could it be my phone or my battery's fault.
edit: 3.2V now during testing...
edit2: went all the way down to 2.7V during the testing (about an hour passed) and I experienced heavy screen flickering at around 22% left of battery and then the phone just shut down. Battery temp was at 39° right before shutdown.
Just recieved a new 1650 mAh battery today in the mail. Gonna give it a few cycles and post the results here.

It's works for me, but not a panacea for all problems.
