Hi guys i really need someones help to explain something to me. I not even had a galaxy s2 for a month and i have been noticing problems with it. I flashed different custom roms because i heard having a custom rom is more battery friendly and makes the phone go a lot faster than having the stock rom in. So i went ahead and flashed a custom rom but i have been having problems with the battery. Fully charge it and within minutes of using wifi and browsing in the browser the battery starts being drained like crazy. Anyways i called the place were i got it from and i have send it in to them for an exchange. They said to me they will have to test it first to see were the fault is before they do the exchange. I have to say here that i flashed back to stock rom with the latest firmware using Kies. Anyways they had it for a few days fully charged it and they say that they can not find a fault and they are sending me the handset back. I have to admit being on stock rom the battery does last longer.
Anyways what can i do next and were is it that im going wrong and is it worth sending it to Samsung directly once i get my handset back?
Does it take few days for the battery to settle and get the proper use out of it even with a custom rom or shall i just stick with the stock and just root and use my phone as normal because other than the drainage there is nothing else wrong with it.
Thank you in advance...

Not true only slight improvements .

No

hey thanks again JJEGAN for replying but why does everyone suggest to go to custom rom then? and i have display on lowest and i hardly have widgets so why on custom rom my battery gets sucked like crazy? do you think its worth staying on stock rom and just root the handset?
Thanks
ps when you say wipe the battery stats i did do that and charged the battery and still the same so were do i go wrong? could it be the custom roms that i have been using and not let the battery have a few days cycle to adjust to the new rom
Why do you want to root it? The phone is a beast on stock. Save yourself a load of hassle and get timely OS updates by staying stock. Root in a years time when the phone gets old and isn't supported anymore.

Read the battery drain posts stop your apps from draining the battery .
Overnight sleep test with GPS Bluetooth and WiFi off on a fully charged battery target 2% drain per twelve hours . Better Battery stats set to show Wakelocks .
me today checked 2.5 days usage admittedly light use = 54% drain

Hye everyone, my name is Ruben and I am 35 years old, I have a small goatee and my hair is thinning and I have a question.
Yesterday, Before I flashed a new ICS rom, my battery life is at 83% and after I flashed the rom my battery dropped drastically to 14%.. and after a while my battery started to increase to 16%,17% and after a while I ignore it and charged until it reached 100%, no issues until now..
My question is why is the battery indicator behave like this? is it okay to ignore it... If it doesn't what should I do to repair and avoid this.
p/s always do the 4 wiping before flashing to public.. sorry.. before flashing new rom. using 1 rom only, and from ICS to ICS.
Thank You.
Yes it's normal, the battery percentage does that when you just installed a new Rom. Leave it a while and it probably will settle. If do not, and it is actually a pretty normal thing with my phone, change the kernel (latest Siyah Kernel, 3.3.2, it makes my battery icon goes insane).
And it happens more often when you reboot your phone.
So.....

Why the battery goes crazy more often if I reboot my phone? can you give me scientific evidence on this behavior. Is this only graphical glitch or it directly effecting the battery itself. btw my battery only goes crazy only after flashing certain new rom.
p/s: maybe siyah 3.3.2 is a steroids for battery, yeah!! gokhan steroid...

Happens to everyone. Give it a full charge/discharge cycle to settle. 'Scientific evidence on this behaviour' ? Search XDA. There are dozens (at least) of threads/posts that have been written about the 'battery weirdness' of the SGS2 in the time I've been here.
It's a statistical glitch, nothing more. If it were happening with every rom you try even after that initial charge/discharge then maybe it's an issue with the battery.

Okay. Then it is decided.. Normal Behavior. Maybe there should be a new thread that titled as :Android, The Normal Weird behavior,that display the list of weird behavior that is normal that happens on android phone.. like mine was. or a thread that display the list of Normal Weird Behavior that happen to android users like Flashing disorder, craziness of F5 button, user became retard when rom has 3 days battery life.
I have an idea. How bout you start a thread like this ? I'm sure the community will be eternally grateful.

I need some help. I want to make all of the pain go away and send this POS out the window of my vehicle. It has been a cause of so much frustration over the last year.
Most recently, I installed Santods excellent official ICS deodexed debloated ROM. I didn't notice the issue I'm having now before I installed that ROM, but I have since installed another ROM (Jellyblur) and my issue has not disappeared. It started when I was using my camera... i noticed a long delay after I impatiently hit a button while it was thinking. it shutdown. upon restarting, battery went from fully charged to maybe 20%. A couple pictures later and it shutdown again and upon restarting showed maybe 3%. It's not just the camera that causes it... GPS, browsing, calls etc. can all trigger this behavior. After showing a battery level of 3%, I plug it in and it is instantaneously at 65% or 72% etc., but never showing that its in need of a full recharge.
Is there a chance I screwed up something that "tells" the battery it's time to shutdown? Here are some logs from the most recent episode.

&
https://www.dropbox.com/s/qj19s4tegj0bdtc/1363286210391.log
Any input would be sincerely & greatly appreciated. I'm mentally exhausted from this device.
Same thing happened to me quite awhile ago,I think it's just a dead battery.After switching batteries the restarts stopped.

Here's why I am still reluctant to believe it's the battery.
1. I was getting a full day of normal use out of it the day before I installed the new ROM.
2. After achieving a total drain of the battery, upon plugging back in , it shows the charge is already at + 50%.
disclaimer: I have no prior experience with owning a smart phone and dealing with batteries, so I have no idea how they are supposed to act. Limited experience flashing ROMS and no real knowledge of common problems that can occur when flashing etc. etc.

2 Things to consider. The rezound battery is all that is available atm and it is rated at 1640mah vs our 1400 mah.
A new battery is usually not more than 20 dollars
If you are having these problems ensure you are following the suggested directions.
Install ICS Radios
4ext Recovery
Wipe all except sd card
install rom
I have returned to GB rom and i stay on the ICS Radios with 0 problems. So no matter what rom you install i would suggest the new ICS radios. I have installed the new radios in 3 other phones besides my own with 0 problems crossing ICS radio with GB ROM.

I will mail you a thunderbolt battery I have left over when I owned one. So you pm me your address and I will mail it free of charge. That's how sure I know its your battery. What you have to lose? If its not the battery then you got an extra battery.

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this
5) Read about jb settings/issues.
Sent from the little guy
Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.
You searched Ebay for "Samsung genuine 2000 mAh battery" or similar?

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.
