stock 2.1 rom 10% battery drain per hour when sleeping
sc 2.9.2 UV 50 kernel (dont remember the full name) 3-5% sleeping in my pocket, BUT 1% drain every 3minutes when the screen is on the LOWEST setting.
Just odined back to stock, and 2.2 was already available to me.....so i OTA upgraded and my battery battery is even worse than that of stock 2.1. 12% percent for sleeping AND crazy battery drain when using the screen... i cant get over 7 hours of using my phone moderately....
warranty is voided since i rooted right???

dont u guys even dare telling me to recalibrate my battery and all that nonsense. none of this works.
No its not voided, you got the update via ota right? As long as you don't bring it in there rooted you should be fine.

Technically yes, but if your back to 100% stock, with no root, then know one well know you rooted.

Have you checked spare parts to see whats eating your battery?
Here are some things you could have done or do.
-Clear battery stats using terminal emulator
-Use app called juice defender
-Use UV kernel (seems like you did)
-Use Set CPU and bring down max frequency to 800MHz.
-Turn off GPS, Wifi, Bluetooth when not in use.
My suggestion is Odin to DI01 and then get the two OTA's EA28 and ED01 and then just run complete stock, and do not install ANY apps, yes I know who wants to run a phone with 0 added apps, you can update any stock apps, but if you run your phone for a day or 2 with just that setup and your having the same issue then go to verizon and get your phone replaced, also keep track of any settings you change, you want to try and keep your phone stock as much as possible, the only stock setting I personally would change is not have live wallpapers.
If your phone is over a year old, you might want to consider getting a new battery for it. No rechargable batteries stay 100% for over a year.

The phone has not been out a year, so its impossible for him to have it longer then a year.
Good point
Seems like this phone has been out damn near forever. Was trying to help. You have a better idea, or do you just troll these forums looking to bust peoples' balls while offering no actual help of your own?
the fear i have with taking it to Verizon is that. i didn't originally buy the phone. i got it of craigslist....so another question i have is, is there a warranty sticker to show if its ever been taken apart? maybe the previous owner replaced it with a cheap POS screen, that why it eats more battery...

Hmm ... I'm not sure about the replacement screen theory ... that seems like a lot of work for ??? benefit.
I second the advice about going stock and not installing any apps. Also, I don't see that you listed some of the things from Battery Use and Spare Parts that are listed as taking up battery life. There are apps that start things up automatically (e.g. Pandora always starts a service when I connect my bluetooth headset, even though it doesn't do audio and I've never used Pandora over bluetooth) ... sometimes you can change this in the settings, sometimes you have to decide how much you want to live with the app.
Out of curiosity, do you leave WiFi on when not connected to a network? I find that sucks battery pretty bad. I use Locale to turn that off when not at home and only turn it back on if I need it. I also used a widget called Traffic Monitor for a little while to see what was using data.
Honestly, you won't be able to return it to Verizon. My husband bought an Ally off Ebay and found out when we got the phone that something wasn't right, so he went to Verizon store and once they found out where it was bought they didn't even want to help him out.
I would suggest calling Verizon and tell them that the phone you have now doesn't work period. You'll need to emphasize that you need a phone that works. I called Verizon the same night that the store didn't help my hubby out and after an hour with the customer rep, I was able to get a new Ally ordered for him and his upgrade date wasn't until Dec of this year. He got his new phone late Feb/March I believe.
If they say they can't help you, keep telling them that you need a phone, and then ask them if they can see if a supervisor will be able to help you out. I stayed on the call with them, until they had that new phone ordered for him-I didn't give up. If the 1st day you call doesn't pan out, call them the next day as each rep is diff and some are really wanting to help, others couldn't care less.
Hope this helps you out.

I did offer a suggestion, which is the same thing that Verizon would ask you to do, and its the same suggestion even most Carriers should ask you. Same with a lot of computer companies should ask you when you are having issues with your computer.
Reset your machine to standard stock, run all your updates, don't install any apps, and see if it still happens, if your battery is just as bad, then we know its either your phone or battery, either way Verizon will trade it out for you, because honestly what else can it be? The only way Verizon can really say tough luck and deal with it is if the battery life he is saying he gets, is what everyone else gets, which we all know is not true.

I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...
I just installed CM7, came from the community rom 2.1.
I am suffering from severely reduced battery life. It appears that 30% of my battery used comes from cell stand by - which is unusually high under my standards. I am not sure what is causing this, time spent without signal is only 1% for me. If I turn off 3g and only run on wifi, it is the same thing so I feel like it has to do with the cell radio. I did a *228 option #2 - but nothing, cell stand by still consumes massive amounts of my battery life. Does anybody know what is causing this, or have experience on how to fix it?
Thanks in advance.
Is anybody experiencing similar problems?
What radio are you using? Cm 7 doesn't need to use the ec09 radio but I've had the best results with it.
what kernel are you running?
You may have something running in the background eating up batt life.
Run terminal emulator and type exactly this minus the parentheses
su (hit enter)
Dumpsys power (make sure the space its there and hit enter) you should see a value of zero on the last two lines if you don't have anything keeping your phone awake (this is what I suspect is happening) if it says anything other then zero do a search for poke lock or wake lock...there is a way to fix it...its just not coming to mind right now and I don't have my pc in front of me
Edit: if all else fails reboot to recovery via power button menu reboot recovery.
Wipe everything and flash again from the recovery that came with cm7

I am currently using ED01 for my radio. I hear good things about EC01, but I also heard it can junk your SD card - so I am not sure what to think. Will it only junk the SD card during the install, or can it do that at any time?
I am using the glitch kernel.
This is what I got:
mLocks.size=0
mPokeLocks.size=1:
poke lock 'PhoneApp' : POKE_LOCK_IGNORE_CHEEK_EVENTS
What are the effects of that pokelock? How long does it take the phone to go into deep sleep that is being prevented?
Thanks a lot for your help.
The ec09 radio is not gonna hurt your sd card...its ec09 rom
that eats cards so no worries there, but considering you have a poke lock on that is what us keeping your phone from deep sleep and draining your battery...if you get good signal currently, I would get that poke lock off, and not worry now about the modem being your number 1 battery drain, I'm not sure how to get rid of it but I know it was discussed here a month or so ago I'll see if I can find the fix...and deep sleep should happened a few minutes after your screen shuts off maybe less
Sent from my SCH-I500 using XDA App
I'll look, too. Let me know if you know how to get that poke lock to go away.
Thanks so much for your help =)
No problem, You could also try going into recovery and run fix permission and then after you boot do a dump sys power and you will probably see its at zero...call your phone and the wake lock will probably be back
I can't seem to find a fix other then doing a full data wipe and rom re flash...I'm just thinking out loud, but did you wipe everything before flashing cm7?...our did you restore apps with titanium backup? I'm running the 7/17 build with the glitch m.l. kernel and I have no poke locks, I know its a pain but I think it may be your best bet to re flash the rom use the kernel cleaning script or at least make sure you wipe everything and re flash
Sent from my SCH-I500 using XDA App
Yeah, I wiped data before. So you suggest wiping data again and reflashing the rom? I restored my apps with titanium backup. Also, since you don't have that poke lock, what is your battery life usually? How many hours do you get out of your phone? How much screen on time, etc.
Chiming in. I have the same problem. Used to get over 2 days on ComRom. Now i'm lucky to get 24 hours.

When you do a batch restore with tI-bu make sure you only use restore user apps and make sure you always choose to restore just the app and not data also.its possible restoring data may be causing the poke lock? Especially if you restored old system files, you only want to restore apps with titanium that you downloaded on the phone, not apps that came with the rom. which is also why doing a full data wipe and re flashing may be your best bet
If I don't look at my phone at all I can go the whole day and only be down to 75% at dinner time, and I've also had days where I need to charge it by 4 o'clock from web browsing, texting, flashing roms, or having to boot to recovery a lot, also listening to music with out the charger plugged in (about 2 and a half hours between
Commuting and going to lunch.over all I get better battery life then I did on com rom and its way faster

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.
---------- Post added at 11:09 PM ---------- Previous post was at 10:59 PM ----------
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.
Hi,
I have recently (half a week ago) updated my SII to Jelly Bean from ICS. It's fully stock without root. However, I noticed right away that the battery started draining very quickly and the phone sometimes gets hot. Did a factory reset. Factory reset the phone and format the internal SD and remove the external SD. Didn't help in the slightest. Phone starts draining after resetting. I have tried to flash another stock JB ROM (XEU) and afterwards factory reset the phone again. No dice. I installed CPU Spy to see CPU consumption and it says the phone didn't go into deep sleep at all and 95% of the time it was at 200 Mhz over an 8 hour period or so. So there's a wakelock that's keeping the phone continuously on.
At first, "Media" in battery settings in Settings was the culprit, it drained about 50% of the battery. I have searched the web and it's a pretty common battery drain on JB. I did try to disable the service and its battery consumption went down dramatically. But for some reason it turned on again. But right now Android OS and Android System are both draining most of the battery. I have also installed BetterBatteryStats and according to that app there is a partial wakelock called "NlpWakeLock" by Google Services that's draining most of the battery. Last night, around 60% of the battery got drained overnight (80% > 23% to be precise). Which, clearly, is unacceptable.
I'm at my wits end. I have no idea how to solve this and because I really like the new JB features I don't want to go back to ICS (I did a fresh ICS install and the battery drained 2% overnight which is how it's supposed to be).
If there's any information you need to know let me know. Any help is appreciated!
Go back to GB with speedmod kernel is an option.

If yes then switch your kernel to apolo it's gives you good battery life

Do you bother reading the posts or just have a compulsion to post any old crap.
I see your advising people how to root,then you open up a new thread asking for help about rooting your phone.
And you are continuing to spam threads posting what other people have said already.

Do you mean going back to Gingerbread? I haven't figured out what the speedmod kernel is yet but if I were to switch back I would rather switch back to ICS. But preferably I'd stick to JB since I do love all the new features and options. I'm willing to flash another JB ROM without the battery drain issue. However, all stock ROMs that I have tried had the issue.
Do you know of any good JB ROM? I prefer to keep it as stock as possible. I did root when I had ICS installed though.
Battery Drainage is very common in JB Stock

If there's any information you need to know let me know. Any help is appreciated!

Hey Kaigo ,
I have faced the same problem as you have faced ... Gone through a lot of problems to fix this Many of the Stock JB's for GS2 are having a lot of issues with the battery drainage
Well I had found a solution to this problem You can try installing the JB France update (XEF) & the UAE update (XSG)
It worked pretty well for me Try it and let me know if it worked for you
Regards

Wow, nice. Exactly what I'm looking for! I'm downloading the XEF update as I'm typing this. I'm going to try that and I will let you know the result.

Do you bother reading the posts or just have a compulsion to post any old crap.
I see your advising people how to root,then you open up a new thread asking for help about rooting your phone.
And you are continuing to spam threads posting what other people have said already.

Well repeating other peoples posts isnt helping anybody.
An update. I've installed the XEF update initially it had the same draining issue. However, I've also cleared cache and data in recovery mode and it seems to have solved most of the issue. I've got pretty good battery life now (about 1%/h idle).
But I did find another culprit draining the battery which is Dropbox. According to BBS the processes "wlan_rx_wake" and "h2_hsic" were draining the battery but I've uninstalled Dropbox now and it seems to have solved the issue. I really use Dropbox regularly though. Anyone got any idea what could be causing that?
Thanks for the help so far everyone! :laugh:

I have always had that feature disabled since I don't want to use it anyway. I have no clue what could be causing it. I want to use a packet sniffer to see what is sending and receiving data but the phone isn't rooted so I can't really do that unfortunately.
Hold on, I'ma freeze it with TiBu.
Test time.
PS: You really need to root that phone.

I just greenify Dropbox (actually, all apps which rely on an internet connection). Unfortunately for you, it requires root. IMHO, almost worth rooting for, although there's many better reasons than that.
Greenify is almost like a temporary freezing of the app, by stopping all background processes for the app. They automatically restart when you launch the app, and automatically turn off when the phone goes to deep sleep.

Well Dropbox always keeps on syncing stuff from the cloud and that might the real cause You should disable all the automatic syncing and keep it to manual sync as it syncs only on your commands and saves your battery!!

Check how much data is being downloaded. If a lot is being downloaded off WiFi, switch it off and see if that stops your drain. Then switch off Data on your cellular. Just to check which one's causing the drain. Believe it or not, I just rebooted my home wifi router and battery drain issue was over on my Galaxy S2.

I had previously rooted my phone when I was on ICS. I never used it too often though. I wanted to use Nandroid. I have no clue how to root JB though, without flashing a modded kernel (which I did with ICS).

That's very interesting. This might just be a good reason to root the phone. So I can use network log or shark to see which apps are sending and/or receiving data. I have this feeling Dropbox is going to be one of them..

Hmm, but I guess that you can't really freeze apps like Whatsapp, since you wouldn't be able to receive any messages then until you turn on your phone. But I'm getting convinced to root the phone again so I'm definitely going to give it a try.
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.
