First, I apologize for my bad English.
I very doubt with my battery life. e.g. Today, I had been using my phone about 9hrs before battery dropped to 1% and after a few minutes it grew up to 2% and after a few minutes it dropped to 1% and grew up to 2% again
e.g.2. I turned off my phone when it has about 50% battery and after I turned on the phone, my battery directly dropped to 13% and after a few minutes it grew up to 25% WITHOUT charging.
I tried to wipe battery stats in CWM recovery mode, delete batterystats.bin, pull of the battery for 2-3 minutes, use battery calibration app, change the ROM or kernel or modem and it still no change
I am using Criskelo Rom v34, Speedmod k18 kernel and XXKL1 modem, edge on, sync off
Yup, seen that as well.
Just quit messing with all those battery related things, charge it to 100% a few times and use it up a few times without flashing roms kernels and wiping stats etc.
It should be normal after that. Give it a week or 5-10 cycles or so.
Thanks, I will try it and come back to review : )
i also had this problem once. i just kept using my phone as normal and the problem fixed itself

Hi, I've been having some problems with my Galaxy S2. About a week ago(maybe a day after flashing MIUI), my phone wouldn't boot normally, and only gave me a symbol which I ment battery overheated. Only way to start it up was CWM. So I did that for a few days, and then the battery drain would get really intense. It'd be at 100% for a few hours, and then suddenly it'd drop to 80% in a minute or two, and then it'd go normally down to 70% and then down to 40% in a few minutes, etc.
It wouldn't charge when I plugged it into the wall, either, and it's not possible to turn the phone off either, it just starts up again by itself and gives me the "YOUR BATTERY IS OVERHEATED/AT 80% BATTERY" error. But even if I plugged it in in that position, or actually running it wouldn't charge for a few hours, and then it'd start charging randomly for about 5 minutes. So after a full night of charging (8 hours) it'd get about 30% battery recovered.
I didn't really read into it any and just figured buying a new battery would fix it, but it didn't. It still won't charge properly and the drain is pretty intense still. And still gives me the overheat sign, and won't boot properly, etc etc..
The reason I haven't just tried flashing a different ROM is because I live at school where a 100-300mb download is impossible to pull off, and I won't be back home for over a month.
If this is too long to read, lol here's a summary:
Flashed MIUI
Battery won't recharge
Drains fast
Phone won't boot properly
Bought new battery, same problems
Live at a place with no proper internet connection to download a different ROM with.
Does anyone have any idea what it could be? The rom? Some rampant application running wild in MIUI? The phone?
Oh and also I've tried re-flashing MIUI, and clearing the cache, data, battery stats, etc etc.
Thanks a lot in advance!
Have you tried to flash back a standard rom?

Is anyone else having issues with this phone loosing around 20% to 30 % after a restart. It doesn't happen everytime but sometimes when the phone is turned off and on the battery drops from, for example , 50% to 30%. I had this issue with official roms and unofficial roms.
Hi mali019, this happen to me as well, i'm not sure this is cause by the battery itself or the phone itself. My phone will auto restart when the battery usage is @ 4x percent. After itself restarting. The battery will drop to 33 percent every time. I'm swapping a battery with a fren of mine and started testing today. I'm using KG6 roms.
never had that problem...
Do you guys quit apps or just press the home button? Use the in-built task manager, it's good.
I don't use taskmanagers. Only use the one that comes with the phone. This problem happend on every rom i tried. From 2.3.3 to 2.3.4 . I'm gonna buy the new 2000mah and see if it happens again.
Just now i pulled out the battery without turning the phone off and battery percentage dropped from 41% to 22% . Currently I'm using KG6

Isn't that what I've said?
Anyway, you can try installing Watchdog from Market to see if you have apps misbehaving and what is using you cpu.

The problem is not an app using the battery. The problem is the phone loosing 20-30 % percent battery after a restart. The phone is not displaying the correct battery percentage.
I even had the battery percentage increasing after a restart without being pluged in to a power point. For example I'll restart the phone for any reason with a battery percentage off 50%. After the restart the battery percentage will show 23%. Sometimes the percentage will increase like its on charge. It will go up to 30%.
Never had this problem better get checked the battery in Samsung service center
Said that because it happened to me that if the phone gets hot, percentage drops. Later, it returns to a higher percentage.
I was experiencing the auto restart and instant battery drain issue while using ninphetamine 2.1.x
After changing to other kernel. No more auto restart nor instant battery drain issue.
You might need to a battery calibration.
I got a new battery ( Perks of working at a phone shop ) hopefully it will fix the issue
I also notice that it takes quit some% after each restart but not 20%. Actually the battery was good when I first got this phone. But after 175 apps installed, battery isn't good anymore.

Moving to Q&A
Today I left my phone in my room and after an hour I wanted to check my emails before going to bed the screen did not turn on so even after a long press on the power button, so I removed the battery (it was ice cold) after replugging it booted and voila there was a huge drop 50 percent perhaps? So I said to myself, I think I left a resource intensive app running and forgot about it and went to bed without plugging the charger, 3 hours later I wake up thinking it would give me a critical or charge your phone dialog, but instead I have a battery that charges itself ...
Now in reality that would be cool but i think there is a problem. Using the ninphetamine 2.0.4 kernel for a few days for bln but it was disabled, stock rom.
I have attached two screenshots one taken right after and the other one 3 hours or so after.
I don't think that I would need a recalibration after a few charges the phone is not a week old.
Hi, I have this exact problem with cognition+ Siyah kernel, how can I fix it??
So I changed the kernel and everything seems ok now, my problem was with Siyah Kernel.

I experienced same problem - I was browsing, then phone restarts itself and the battery is instantly on 18% (from 50%).
And then started to recharge itself.
Stock 2.3.4 ROM (version XWKH4), running the same configuration for nearly two months now, with only few restarts (once in 20 days), no new app installed recently.
Maybe some glitch in internal electronic?
Same problem, just a bit more drastic. My phone seems to freeze, in which I have to manually restart it. And then I see the battery falls sharply. This is on stock Firmware (unrooted) too.
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.
I did a search and found similar threads, but it seems that my problem is slightly different.
I have been using different CM9 Roms over the past few months and they have all been pretty stable, and the battery life has been pretty good.
However, I was on a trip last weekend and all of a sudden, my phones battery went from 100% to 40% in a matter of hours with the phone screen completely off.
I tried flashing other ICS ROMs, installing the blue sleep fix to no avail (wiping in between each, even doing a fastboot wipe as well). Then I restored a nandroid I had of a CNA ROM where I knew I wasn't having any battery life problems, but the problem still persisted.
I installed better battery stats to see if I could get an idea of what could be wrong. For example, this morning, my phone was charged to 100%. I took it off the charger, and it literally sat on my end table for 2 hours. I didn't touch it. I then looked at it, and it was down to 80%. I went into better battery stats, and it said under the partial wakelocks that the longest wakelock was only a few seconds. I then looked at the processes, and it said that deep sleep was the dominant process at 1 hour and 45 minutes.
Obviously if the phone is in deep sleep it shouldn't be dying that quickly (I would assume). Is there anything that anyone knows might be wrong with my phone that it is killing the battery across all these different ROMs?
My only other option is to completely wipe the phone and sd-cards and install nottachtrix, since I was getting 2 - 3 days of battery life on that ROM.

Have you tried the app CPU spy on the cm9 ROM to see what's eating at the battery CPU wise and to see if your getting deep sleep?

I have been having this issue for a while, not sure if it is my phone but it is not the rom. Been through 5 roms and it still has a problem.
The phone seems to be charging to fast... After a 5 minute charge, it charges to over 15%. Not normal...
After an hour of standby time, the battery drains by 7%
5 minutes on youtube = 10% battery. Charge won't last 3 hours, it use to be lasting 11-12 hours. Motorola is sending me a new battery, but I have bought a new battery online and it is kinda doing the same thing.
Is there a mod I can download and install it inside of recovery to make it better?
Thanks.

The problem seems to be the 'battery stats' failure.
It usually occurs when you keep changing ROMs over and over. If repeated, the system fails to detect the correct battery information(like battery percentage, charing phase and etc).
There's two ways to get this thing straightened up .
The first is to go to CWM recovery(if you've unlocked your bootloader and installed CWM recovery)
I recommend you to fully charge before going through this steps.
1) go to -advanced menu.
2) go to -Wipe Battery Stats then select Yes.
3) Then charge till 100%, and then disconnect from AC charger.
4) Discharge until it reaches 0%, then recharge again.
The other way is to make use of 'battery calibration' app by NeMa.
You will be able to find it on Playstore.
I hope it would help solve your problem
Wiping battery stats doesn't do anything. That's why this selection was removed on recent TWRP 2 recoveries. People still use CWM???
