I also have this type of problem when my phone completely runs out of battery and when plug it in charger it bump to 48%.
I dont the reason behind it that why it happen and whats the reason behind it.
If you have recently rooted your phone and have flashed custom rom in your phone than you may face problem of mis-calibration of battery. For solving this download a software called battery calibration apk ( google it ) . Your phone must be rooted if you wana use that app. but before you calibrate your battery make sure you charge your phone to 100%.
when you 100% open that app and grant the super user permission. Click on calibrate.
what the app does is that it will remove batterystat file from our phone and automatically it generate a new batterystat file in your phon. Thus any faulty or mis-calibrated file will be removed and you will get good battery life.
after calibrating do some cycle charge mean from 100% to 0% and from 0% to 100% without interuption. Do it for 3-4 times and you will see a drastic change in your battery life.

Calibration of batteries is a myth, battery stats is cleared every time you unplug a nearly fully charged device. Also draining modern batteries to dead is not good for them at all so I'd discourage it unless necessary.

Battery indicator inconsistancy

Hi
Its been 2months i bought galaxy s2 and 1 thing i dint like is the battery life. Im getting only 5hours of battery life with internet on. Ive installed the battery life saver apk Juice Defender and still the battery life is very less. Please suggest me something.
Also i read a post in the same website saying that the android 2.3.3 has this OS problem. The form told me to shutdown the phone and remove the battery for 5mins Nd use again. But when i shutdown the phone the battery was 45% and when i switched on again,the battery indicator was 15%. Then after sometime, it increased to 27% without charging and then reduced normally. Please help me with this, what might be the reason for battery life being inconsistant and what can be the solution

you might have an application that keeps your phone awake. what i mean is by having your screen off there are applications in the background still running. So my best advice is Juice Defender does not do anything and infact it drains more battery than saving it.

probably yes... Bcos when in idle, sometimes the display suddenly turns on and again after sometime. Is it possible that the phone is infected with virus?

No you not have a virus but probably you either need to update your firmware or change kernels if you are rooted...

I believe you have rooted your phone, if not follow chainfire thread ( http://forum.xda-developers.com/showthread.php?t=1103399) for rooting the phone.After rooting goto CWM recovery > Advanced > Wipe Battery Stats. This should give you a clean slate on the issue of battery inconsistency.
As for battery drain, remove all battery saving apps like JD, they infact consume more battery. Install Betterbatterystas apps from market ( paid app) or the free version available on XDA, and check for the partial wakelocks / kernal wakelocks to get to know what apps are killing your battery.

Which Rom you are using at this moment...
Yes Smasung Stock Roms do have this problem as reported by Some users.
If you want give it a go ... Try Battery Mods for S2 ... They do help In this Inconsistency.
Depending on your Current Version You can find Battery Mod which will help you.

Sometimes I have the same problem. I dont know if it is caused of a program running in a background or what, but reboot helps

I know the reboot helps.
But usually I put it on charging at night before sleeping.
And when I wake up in the morning, the battery % becomes even less than what it was when i plugged it in.
I'm usually in a hurry then to leave for college in the morning . Can't go to college with battery % less than even 10
Thanks for the reply anyway !

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.
EDIT: Does Your battery go hot while charging? Oh, and try to wipe battery stats

Maybe there is really some program that is causing that. I had this problem rarely so I never cared. I had one program called Batterymonitor or sth. like that and it was the reason. Do You have such a program, that shows Your battery level or temperature?

Yes, I have setcpu and rom toolbox.
But would these applications really cause this problem?

The x10 charges the battery to full then if still plugged in it will stop charging until batt drains to set level ,then will charge to full again and over and over all night. X10 wont over charge batt when left plugged in. Kernel/bootloader handle this. There is an app current widget that can log charge levels.
EDIT: I had a tip on charging here but removed it after further research read more about batt here..

EDIT: the best tip I usr for battery life is, let batt runout until phone shuts off, then pull batt, then plug in charger, then replace batt into phone, then phone will boot, enter xrecovery on first boot and wipe batt stats. After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge . I do this about once a month, when phone starts to shut off around 15%

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.

how to overcome the Battery Life Problem in cyanogenmod

This is a simple way to increase the battery life in cyanogenmod... this worked for me,..
1. Goto cwm and clear the battery stats
2. Charge the phone to 100% (make sure it is 100% by checking the battery status..)
3. NOw allow it to completely discharge ... do not connect the charger until the phone is shutdown automatically...
4. Once the phone turned off due to complete draining of the battery, charge it and use it normally..,
hope it helps
i have a better idea, bring powerbank 5200ma or up, when u go out. ur device will not run out battery even on hard gaming all day long. like i did

yep, maybe it doesnt help but it work for me
1st charge 100% while phone is on
2nd reboot to cwm n wipe battery stats
3rd turn the phone off then charge it to 100%, cause it will tell u that ur battery isnt full yet (charge it about 20 minutes or more)
4th turn it on while still charging
5th unplug the charger n use ur phone as usual

I'm not trying to argue here, I'm just saying that wiping the stats won't help improving battery life. So if you say so, on what basis?
Anyways, cheers!
not improving battery life but, correcting current battery stats. it happen when u often switch rom n restore from cwm then u feel like ur battery drain more quickly than usual, so i tried the method i post earlier n it works

The battery stat is wiped to calibrate the battery... We may have to calibrate the battery after every rom install..

[Q] Help me to resolve this battey problem.

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.

Battery drop issue/problem solved.

the most annoying problem in canvas hd is the battery drop problem.
For some users the battery may drop all of a sudden from 34% to 12% while for some it may be different. For me it was always 34% - 12%.
Now the one important thing that I observed was that when I used to charge my mobile , the charging jumped straight from 76% to 100% . In my view the battery was never charged for the last 20%. And it was this 20% that appeared as the sudden drop.
Now coming to the solution..
Battery calibration and wiping batterystats.bin actually never solved the problem because I tried both.I don't know if changing the Kernel did.
So I have come up with one solution that won't disappoint you..
Follow the steps..
1. Let your battery drain to below 10%.. say 8% ..
2. Charge your battery like u always do..
3. When the battery reaches 100% , do not disconnect the charger, go to System settings and then battery and check the graph..(don't disconnect the charger because doing so will reset the graph).
4. notice the sudden increase in battery charging.
5. Use the phone as u always do and let it discharge to 70% ..
6.Here comes the LIFE SAVING STEP..Now what you have to do is charge your phone in one go..there should be no interruption in charging..If the electricity goes off even for a second..the whole process fails..so prefer using a UPS..
7. Let the battery charge to 100% and use normally.
8. Its my guarantee that the battery drop is gone.
The bad part..
The problem reappears after a reboot.. and we have to repeat the procedure again.
Come on , Don't be PANIC about sudden drop ,First of All letting the battery drop from 100% to 1% leads to fluctuation in battery volt,be aware about it ,Don't use your chd while charging is most important ! if you may use your chd normally like noob users who only use fb.watsupp etc whenever they need ,it won't drop like 30-12% ,fast drain made by users leads to bloat of battery ! high volt ofbattery from 90-100% has corrosive effect if you drain fast then your battery would PREGNANT or fat or swell
DON"T PANIC USE YOUR DEVICE AS A PHONE

well this is silly I've had same problem but after battery calibration it doesn't appear again and if you're using your phone processor constantly at high power As for Huge game or something then faster battery drain is normal !
I use DS Battery Saver which helps me saving my battery as per my use ! worth a try !!
