I installed the Nameless v4 yesterday and v4.1 today.
On the Froyo roms my battery pull on idol was -2 to -10ma [i use battery monitor widget]
Now on the GB i am getting -100 to -275.
Is anyone else experiencing this kind of draw?
[I do understand that the GB is a wip]
I can't speak on the new build, but I was running the 4.0 build and my battery ran down so quickly that I thought I left my gps running with a connection. I also was having quite a lot of issues with the rom, so I thought it was a fluke. I'm on 4.1 and it's been running much better, so hopefully the battery drain isn't as great.
Definitely sounds like you've got a runaway process or wake-lock occurring somewhere. Have a look around the processes and see if something's keeping the CPU running hard. Also run a dumpsys power from adb and see if something's keeping it from sleeping.
Im getting quite the opposite here. It's been almost a day and after moderate use I have a little over 50%. It's amazing because I would be getting half of that on a full charge in froyo.
Looks like it may have been the Widget itself.
But i am not sure, if i closed the running application of Battery Monitor it dropped down to -1 or -2 but then ten mins later its back up to -300.
The other possibility is when i kill the app the widget gets no information and defaults to a low number.
Thank you everyone for your input. I will keep on testing to find my battery killer.
I also may try uninstalling K-9 mail and reverting to the stock Mail client
It being on stock kernel and a lot of debugging features being enabled will do that to your battery.

A lot of people have reported poor battery life with K-9, FWIW, though the K-9 devs say there isn't an issue. I haven't used it myself so I can't really say... you could try this though:

4.1 drained my battery from 100% to 10% in about 4 hours today. But then I plugged in and rebooted and I had 40%, so I would imagine a battery stats wipe is needed on my phone.
My home button does not work as well, so I am going to re-install again and see if it fixes these issues.
Anyone else had the home button issue?
Edit: The re install fix the home button/lock screen issue. Will report back on the battery tomorrow.
Weird, my battery is AMAZING on Nameless. After 11 hours with using Screeble, with moderate use, I'm at 50%.

I tried Nameless 4.0 and it used less than 20% during the first 6 hours.
Whenever I flash a new rom, it uses more power at first and less and less as you use the phone. Some people insist that you do not have to kill the apps especially on Gingerbread.

Assuming you're talking about task killers, "some people" = Google. With the exception of apps like Watchdog (which just notifies you of apps using excessive CPU, like >50%), task killers hurt more than they help -- they're all effectively scams.
Google's serious techy explanation:

An excellent, understandable article from Lifehacker:

I thought I read somewhere (either the EC09 Leak thread on the Nameless v4 thread) that auto-rotate is causing 50% cpu for this EC09 leak, would that have something to do with battery drain?
http://forum.xda-developers.com/showthread.php?t=1131213&page=15
Thanks
saw the one about auto rotate and turned it off, then i was in the -50 to -100
But that is still bad coming from froyo`s -2 to -10
So i went back to Com Rom and will be awaiting the best Devs on XDA to crack the Leak and make some fantastic ROMS, just like they did with Froyo!
Keep up the good work!

I suggest disabling auto rotate, rebooting, and then never turning auto rotate on again. (even toggling on/off can get the events/0 process stuck at high cpu usage) Once I did this, the full bloated GB leak is spanking Froyo battery life.
This more than makes up for the poor contacts scrolling for this guy.
Also full bloated GB leak appears to be much safer for you SD card than other versions of the leak.

This. My battery life (and signal dBm) has been MUCH better even at work, which is notoriously hard on the battery due to being so well insulated.
I've had ZERO issues with the SD card so far, and it's a huge mystery what exactly is causing that. I ODIN'd the leak an hour after it was posted, then the NamelessV4 rom, then the NamelessV4.1 and haven't had a single issue. There needs to be a better process of defining it, and I'd be willing to bet it has something to do with the recovery the person used when it was flashed.

I was one of the unlucky ones that had a 16GB get ruined. But i know it was my fault. i didnt odin the original leak i went from com rom to nameless and it botched my card. But i am lucky i had my POS BB Storm 2's 16gb. I also went and got a $10 4gb card that i now use when testing out the GB roms [better safe than sorry]
I will try that with the new rom and let you know what i am getting.

That's definitely what I'd be leaning towards. I also took the added (though not really needed) step of using the GB root exploit app, and confirming all was well before ever flashing CWM3.xx in ODIN, then going onto the nameless ROMs. I've actually tried to re-create the problem since I stuck in a spare 4GB card waiting for it to happen, but nothing so far.
Everything is so new, it's really all speculation for the time being. I personally don't think it's the ROM or the leak causing the problem, although it's obviously a factor. There are so many different combinations of recoveries being used (as if all of us read directions in full) and ROMs were flashed in different sequences that it's impossible to nail it down.
Aside from disabling auto rotate, I've had no complaints about the leak or ROM. I ran CM7 forever on my Eris before getting this Fascinate, and while I like it, it's a pain to deal with the missing functionality at times.

I went from stock odin to nameless and my card was eaten alive...I followed the steps exactly as listed not missing one thing. So it has nothing to do with flashing from another rom

So, immediately upon flashing the sd card was corrupted?
It'd be nice if there was more cooperation among everyone to figure out the common problem. It seems like for all the trouble reports, there are as many or more of us with no issues. I can't see anything in logs that would tip off a problem, so it needs to be someone who has the issue.
I'm still leaning towards it being a recovery issue. It's odd that some people are saying the files still appear on the sd when viewed through the CWM interface.

Man, that would be awful if the CWM we were told to use is what is killing the SD cards, and a diffr version would have worked :O
I used the CWM linked in the nameless thread and no issue so far, but only 2 days so far.

You have an app that is driving data to your phone, causing the wifi chip to wake the phone all the time. Apparently a system app - a lot of people have been having this issue with KK6.
Beyond this - sorry, but if you are not rooted you will have to live with it. Identifying what is triggering the wifi interrupts requires obtaining a Wireshark capture, this is not possible without root. Even if a common root cause is found for what's going on with KK6, it's most likely in /system itself so can't be fixed without a custom ROM or at least rooting.
If you're not willing to root, why are you on a firmware developer forum? Have AT&T help you instead if you're on 100% bone stock unrooted.
Well if it's an APP causing it, then many many people must be running the same app cause all of the various forums out there are a lot of people with the battery drain after updating to 2.3.6. Even a lot of my customers have mentioned it also.
I doubt it is an APP doing it. I'd bet it is just some bad coding on Samsung's part. They are probably getting a lot of complaints and are most likely already looking into it.
As far as the why he is here if he doesn't root. Well I don't root as well and have no desire to being as stock works just great. (other than the battery drain)
This is a great place to hang out and keep up on other people using various phones. He posted in the General section, not the Developer's section for this phone. So I think his/her question was valid.
If he was asking the question in the Developers section I would understand your concern. But I don't feel you have to be into cooked ROMS to value this forum.
That's like saying to the people who like the "Fast and the Furious" moves to stop watching them because they have a Chevy and not a pimped up Civic.

I'm not rooted with wifi on all the time just got the phone 3 days ago and I'm getting 14-15hrs with no issue down to about 15-20% battery life left before I have to stick back on charger. Could be a bad battery or device, I'm coming over from Sprint after using rooted evo3d and rooted photon.

The forum is called xda-DEVELOPERS.com
If you don't want to root, you're probably better off in the AT&T support forums, because honestly, it isn't worth our time to try and help someone who doesn't want to root fix a problem that is almost sure to require root access to fix, or in this case, even diagnose.
I do believe many are having this issue after upgrading to kk6 (with same apps installed). I had the issue as well.
May be a system app, or something in /system causing an app to become unhappy.
Either way, it's not going to get fixed without Shark for Root captures from those encountering problems.

I don't think it anything to do with KK6. As Entropy said its an app causing a wake lock. I'm run Ingram KK6 without any issues with battery.

Having this issue as well. Phone is stock. Ive been here since the captivate but I hang around with the sgs2. Never needed to root this phone as it works perfectly for me. But I did the update this morning at 100% charge and 9 hours later with no use it's down to 9%. I could go all day with moderate use and be at 30-40% by the time I go to bed.
I read on a rather long on a google forum that many had this issue after upgrading via ota but who knows. I found that wiping dalvik and flashing unnamed update again I have much better batter life. I did read in update that he reverted to an earlier kernel signature to fix the battery drain.
Im going back to 2.3.4 via this method.

Losing 10% of my battery at idle /hour is ridiculous lol. Android os was at 87+% within 3 hours of restart.
Edit:
Okay so I did this method. Took about 5 mins after I got everything downloaded. I did not do the factory reset since it's not needed. Phones back to 2.3.4 and nothing was reset. Have all my sms's contacts, aps, wallpapers etc. Battery seems to be back to normal.
I recommend everyone who did that 2.3.6 update to revert back. To many problems with it.
I never entered download mode on this phone before. Just a tip: Keep holding all the buttons till the phone seems like it shuts off and keep holding them till you get into download mode. Do not let go or else it just powers off.
For the purposes of attempting to fix the problem, I really would like some people to take some Shark for Root captures as described in my Known Battery Drainers thread.
With that data, the root cause of the problem might be identifiable.
So far I've only seen one capture, I really need more unless I can reproduce the problem myself.

I read a possible solution on another forum and tried it with my SGS2 today and am amazed at the difference today in my battery life.
Worth a shot as it does not require anything more than charging your phone and pulling the battery.
Charge your phone to 100% with the phone off (hold the power button for 3 seconds or so until the menu comes up and select power off). When you reach 100%, unplug the charger and remove your battery (some said keep the battery removed for 90 seconds while others said 3-5 minutes). I left my battery out for 5 minutes or so. Put the battery back in and power on.
That was it. My Android OS went back to normal and the battery life today has been great if not better then with 2.3.6 than before I updated.

Quite possible, but still running on the same charge from this morning and am at 28% battery after 14+ hours of normal use which is all I expect (calls, texts and light web browsing during the day over data) and then couple hours of web use at night over Wi-Fi when at home.
The last few days I was charging the phone when I got home from the office if I wanted to use it at night. Android OS was way up in the 60+ range after I first updated OTA and today it has been under 20% and more near 15%, so I'll take it.

Come to think, I probably did not do a reboot after the update and could have been all that was needed.

I did this and saw absolutely no change. 2.3.6 is draining my battery far faster than 2.3.4 ever did. The culprit is the Android OS running at 90%.
I read that it might be an issue with the wifi so I have turned that off and will report back if that seems to fix it.
I read on another forum that att and Samsung are trying to blame it on bad batteries and shipping out new batteries.
What a bunch of crap. People everywhere wouldn't suddenly all have bad batteries at the same time. Sounds like usual BS.
I personally think its just some bad coding that Samsung needs to figure out.
On a different note, I played with the Verizon Droid Razr yesterday. Man that is a really nice phone. I'm tempted to get it, but I work for att and get free cell service, so it wouldn't make sense to pay for Verizon service, even though I think their network is better.

Android OS is definately eating up the battery now. I think it does have to do with wifi, because it seems to be much improved with it off. I'll take a free battery as long as I don't need to exchange the old one.
After upgrading to ICS (via kies) the battery really sucks. Last for a whole day if im lucky. Is this normal??

From what I've heard, it's usually improved - BUT some power management bugs that affected stock Gingerbread kernels but were fixed in all custom kernels are still present in ICS, such as the good old fuel_alerted wakelock - so while it's better when working well, it's more prone to breaking.
I'm happy if my battery lasts for a day as i'm always messing with it(one of these days I might use it to make a phone call)! Have you tried putting it on charge at bedtime? I find that helps a lot.

Upgrading to custom ICS roms is usually a great way to enhance your battery life, because they're always containing tweaks and optimizations!
This worked for me
Device: GT-I9100 (Samsung Galaxy S2 international)
Carrier: Smartone
Country / Language: Hong Kong
OS / Browser / build number (if applicable): ICS 4.0.3/IML74K.ZSLPE
I can confirm that I have resolved the battery drain issue after upgrading to ICS on my device. The problem was partial wake locks caused by the exchange service.
One of these measures fixed the problem for me (it might have been any of these, although I have a strong suspicion that the factory reset is the only relevant one):
- factory reset of phone; didn't restore the settings and accounts, but set them up manually
- wiped cache
- did not reinstall ADW launcher
Hope that helps.
The good news is that now the battery life is definitely better than it was on Gingerbread.

This isn't really true. Once it hits 100% it pretty much runs off the charger.
By depleting it all the time you are ruining the battery that way

Leaving your phone on charge longer than is absolutely necessary ie taking it off charge as soon as it gets to 100% will not affect your battery life and there is also no need to manually calibrate the battery. I installed DXLP7 and was getting poor battery life due to a wakelock, I found and dealt with the cause and immediately battery life improved. In my experience battery life on ICS is as good as it was in gingerbread. Better battery stats is your friend.

I had upgraded my sgs2 to ics yesterday. The new version is draining the battery very seriously. In the previous version, my sgs2 could last for about 12 hours from a fully charged state. But now the version can only last for 6 hours, which is really unacceptable.
Is deep sleep? You can check with CPU-Spy. If not, remove the battery a few minutes and then returned.

I had huge battery drain issues from exchange and email waking the device and constantly doing something. Removed the accounts and then set them up again. Like night and day now, better than gb. On LP7 and never wiped.

Keep a look with BetterBatteryStats, and see if there are any apps messing up.
I have better batterylife with ICS by a margin.
And about leaving the charger on during night, these are kind of myths really, you can keep it on without any worries, and also charge it without being totally drained.
Most of these thoughts come from the old Ni-Cd times with memory effect.
I had removed the Exchange Account yesterday and the battery drain problem disappeared. The account was added back after about 10 hours. The battery usage is now back to normal (a little bit better than the situation before the ics upgarde). Thanks for your hint.
Cheers.
SG S2 ICS Battery drain issue
Had upgraded to ICS when it launched in India and literally went berserk due to the battery drain issue. Googled and googled, found a lot of things, tried most of them (except for changing ROMs).
Then, Voila, last 4 days - a complete twist to my sorry tale. I first disabled the phone backup option (to Google), did a factory reset, said No to most of the options that are asked on restart, and didnt install the earlier applications from the Play store en masse (earlier, had a number of games and other 'what I thought was useful' apps). Now, only have the basic apps plus Poweramp, Shazam and NQ Mobile added. And the result - the battery is back to normal. Phew....big relief as I use the phone pretty much for mails, music, phone.
I want yo add some thing very annoying, I discovered today after upgrading to Resurrection ROM.
In fact, even with the device connected to my car power supply and using Copilot for about 1 hour, the battery continued it's discharge instead of charging.
So what to say and what to do?
Cheers

I own my one X about 300 days now flashing a ROM every 2 days so that's 150 flashes at least and the performance is still much better then the day I bought it. Maybe the battery doesn't like it to much but that's because the one x needs to be connecting via a PC to flash a ROM so that's a lot of connecting/disconnecting the battery.

Your friend is wrong. Straight up wrong. Flash away
The quick answer is yes, the long answer is you don't need to worry about it. Repeatedly wiping and flashing the partitions will over time have an effect. The flash storage used in virtually all mobile devices can only be written a finite number of times. I know a dev who have to be careful of which kernels he flashes because they have bad blocks and only a real slim one will fit now. But it is a 3 year old phone that has been used heavy by a developer. A heavy crack flasher will likely never even come close to flashing as many times as a dev working on a rom. If you flashed a different rom everyday, you should be perfectly fine to last through several years of use.
As for battery, flashing roms has ZERO impact on battery integrity.
I had to have flashed my droid x and droid 2 and droid 2 global once a day at least for about 2 years except on weekends. When working on ROMs and mods I didn't have a choice. But my DX and d2s still run great to this day.
And the entire time I ran those they were overclocked from 1.0ghz to 1.25ghz daily with no thermal throttling. If anyone was going to burn up their phone it should have been me.
My gs4 is following suit. I flash a lot because of projects. I don't expect to have to buy another but I already have began planning on it. The hope is I won't have to and that money can buy the next phone.

I can't help but laugh at the question (please, no offense intended). If this were a real concern most of us here would be in a bad way.
Once it hits 100 flashes, it will start sending Verizon a text saying you are flashing custom roms, then they sent the flash police to your door, be careful.
The Ax says, not true.
On my G3 back in the day, I must have flashed it hundreds of times, np.

and this is what i've also learned from my years of flashing. yes it'll affect, but you'll most likely never get around to the point where it'll make a difference.
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.

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.

As far as the battery issue is concerned,do a clean ROM install through Odin.
