Hi fellows,
Please help!!! last night i have experienced worst battery performance (see attached). Over night battery drain form ~80% to 27% with nothing except WIFI on..crazy ****.
New apps or diffrence i made on S2 were:-
Installed Set CPU - XDA version
Installed CPU SPY - from market
Changed Modem from XXKI4 to XXKL1
Changed Modem Kernel from DK 2.5.2p to 2.4.3 (i personally feel 2.4.3 have better battery performance)
now i have removed Set CPU coz heaps of battery used by Android OS and Android System.
Please advise what i have done wrong here...
thanks

Could be an issue caused by the flashing of a new modem and/or kernel.
Have you run a kernel clearing script or done something special to "calibrate" your battery?
I prefer to shut down the phone, fully charge to 100%, then unplug the phone and pull out the battery for about 5 minutes.
Then put the battery back into the phone and boot the phone.
It is easier for the battery stats chip to auto-calibrate by using a "stress-free" battery.
Just to get all unneeded wakelocks, please post screenshots of the Partial Wakelocks and the Kernel Wakelocks of BBS.
thanks It_ler,
yes is did run kernel clearing script but haven't done something special to "calibrate" battery.
I have just fully changed my phone after removing Set CPU and cleared battery cache from recovery mode, so nothing much for now in Partial Wakelocks and the Kernel Wakelocks of BBS.
For now phone is on battery from last 35 mins with WIFI ON and only lost 1% of battery. Mind you from that 35 mins its been in deep sleep for 30 mins (as per CPU Spy). Monitoring on going, will keep posting...
BTW do you think Set CPU with only one profile configured i.e. Scree 0ff (100-500, priority 80) can chew ~53% battery over night with only WIFI on?

Hi mate, see attached does this looks ok?
Lost 6% of battery in 2 hours 20 mins with WIFI on...
Just FYI..i have now rolled back to modem XXKI4 and Monitoring.
have a feeling that there is issue with XXKL1 modem (i downloaded this form Kitchen Pro app)

Maybe the KL1 gives you a weaker signal.
Under settings > about > status you can see the signal strength.
Mine is always around 92 dBm with 9 asu.
Don't know exactly what it means, but it's interesting to see the difference between modems.
yeah might be Kees, right now am back to my original config i.e. CRR4 wid DK 2.4.3 kernel.
So far its been ~17% usage for 5 hours 10 mins wid 30 mins of GPS On (for runkeeper), 35 mins of display on, all time WIFI on and few calls, emails and messages.
I still dont feel its normal something is wrong, will monitor overnight otherwise flash my last good config (sad its 10 days old tho) or will try siyah 2.6_S99 kernel..any thoughts???

A mobile phone signal (or reception) is the strength (measured in dBm) of the connection to the mobile phone with its network. Depending on various factors, such as proximity to a tower, obstructions such as buildings or trees, etc, the signal may vary. Most mobile devices use a set of bars of varying heights to display the strength of the signal where the device is located.
Equation : dBm = 2*ASU - 113
Less dBm means better signal.Ideal will be close to -60 and you will have full signal strength and close to -113 is extremely bad signal. ASU is a more linear way of representing the signal strength
Sounds not bad, but good be better i think.
But for me, DK 2.5.2 is way better then 2.4.3, about the same battery life as with speedmod k-2 18 test 17, but with some what smoother / faster feeling.
And i must say that for battery life, i found speedmod kernels better then siyah.
Did you have any frozen apps?
I did some freezing like maps and streetview, iám using Sygic.
I did froze Talk, but somehow this caused some drain, thinking that Android it self was constantly looking for Talk, something like that.
So, if you have some apps frozen, take a good look to them.
Any apps updated?
By the way, iám using the setting, wifi off when display is off.
Fast Dormancy is also disabled, my provider doesn't have FD.

no mate, same **** happened over night again lost ~55% battery wid only WIFI on ( it just started happening from last 3 days or so). i always had my WIFI on overnight. Looked into CPU SPY phone never went to deep sleep. flashed SiyahKernel v2.6 and will do battery calibration once 100% charged and monitor...

Did you make log with bbs?
Is battery problem common with this rom?
Folks just a word of advice instead of starting a new thread why not just post in the CheckRom thread about any issue you may have.
For the record battery life with this ROM is excellent therefore the OP needs to establish what is draining their battery, a simple few searches of the forum will give you the answers.

Nop, i got a great battery life with this rom with the latest DK.
45% left since 1d 2h 15m, 2h 38m screen on.
Played Angry birds for more then a hour, a few calls, some browsing.\
But i have the 2000mah battery.

i dont think so as this was not happening before, i think only started when i flashed KL1 modem. just wondering if there is any modem clean up script like kernel one as i have feeling that KL1 modem configs/ settings are still there...
so far i have last 7% battery with 2.30 hours usage (~134 mins of calls and 11 mins with screen on and also WIFI was off all time as i wasnt home)
i dont know whats gone wrong but will monitor overnight with 100% charged

I know this question has been asked really lots of times, but I didn't seem to find cases similar to mine.
there doesn't seem to be any wakelock (except 2 which is incredibly short) and it was in deep sleep mode all the time. but yet, it drains almost 5% per hour which i find is really too much...
I've tried lots of firmware (litening, wamanlite, turkbey, stock, ICS) and removed all the unnecessary bloatware to reduce wakelocks to a state as shown in attachment. but still, they do not have any results, still get less than 1 day life without any usage at all...
Could this be hardware problem? I find it gets hot really fast even when i'm just facebooking.
Or is there anything else can i try to do? this device really started to disappoint me ever since the battery life looks like this.
any help will be greatly appreciated.

maybe try out BetterBatteryStats, duuno but maybe this could help?!
cheers and good luck!
Try Hydrogen-ICS latest version, it seems to be "the rom" today
Battery life is very good and its overall a stable system.
Make sure to "Fix Permission" after first start, reboot recovery and do it.
Also sometimes "to much junk" in your SD card can cause battery drain, copy your files and format the SD card, you might see some diffrence. (i did)

you got 20Hrs out of your phone? grats! as of lately i've been trying alot of different roms and different customization settings from kernel tweeks to CPU tweeks (undervolting/underclocking) and im even turning off every extra setting that consumes battery power apart from wifi
on best with a 2000Mah battery i get 13 hrs on standby and 4 hrs if im playing a game - these days my phone doesnt charge anymore - it discharges even when plugged in
I recommend downloading HydrogenICS, it's good! Download Battery drain, so you can see how fast your battery is being drained.. Also, let your battery go down to 5% then charge your phone
Something is seriously wrong - you've hardly used it, looking at those graphs.
I'd try a stock anything, and if you get similar drainage send it in for repair/buy a new battery.
this is'nt normal , in sleep mode i can get 20 hours and only lose 9%
use hydrogen and neak , and try , if you get the same result so it will be hardware fault
the 3g data it kills the batt very fast,i don think u got a hardware prblm,cause 20hrs an still to go is good ive seen ppl reporting worse...dude instal better batt stat,3g watch dog but remember batt saver apps too run in bckgrnd so i suggest u stay on a stable rom wiv a custum kernel like siyah or neak an watch the batt in better batt stat.....wen i need more juice i switch to airplane mode in nite then rebot in the morning....i don hav any tweaks or uv,oc but ive seen the batt is very good wen i don use the data or wifi or download or update,pm me if any doubt......cheeeerz
You flashed different ROMs the last days? First thing is you should only flash with full battery and after flashing it needs some time (three full battery cycles e.g.) untill the battery works fine for the ROM.
And you may recallibrate your battery. Turn the mobile off and load the battery to full. Then go to CWM and reset your batterystats. Now unload till the mobile goes of and reload to full with mobile off. If you doe this for e.g. 3 times the battery should be recalibrated.
I must say Omegas ICS + Speedmod or Siyahs Kernel. Best ever. Or checkout Paradoxxxs rom very stable but for me not so good xD

bro, 20 hours is with 99% deep sleep is seriously wrong. better battery stats cant tell me nothing, since i have no wakelocks or whatever, and all those battery savers apps, they spent more battery than they can save. when those screenshot is taken, i can tell you for sure, bluetooth, gps, 3g, wifi, auto sync etc everything was turned off. even brightness is 10% (which is even lower than auto brightness settings). anyway thanks for the reply

nope, i always try at least 5-6 battery cycles after flashing to see the real graph. and i've read in this forum somewhere, calibrating battery by deleting batterystats is useless for this phone.

speedmod is a kernel like siyah rite? i've use siyah before, but it doesn't seem like much help. nonetheless, will try them ^^
thanks for all the replies and recommendation, will try different rom & update again (probably in 4-5 days for trying 2 roms
I have exactly same problem. On GB over night(7 hours), battery consumption was around 9%. On ICS more than 20%, but nobody touch phone. I try few roms: wanamlite, omega, bezke, pure. Now i have hydrogen. Better battery stats shows nothing special. Only thing what i can think is wi-fi. if i turn off seams to be better, not that dramatic, but anyway not that good like on GB.
strange...
let me ask this... what does the yellow color in the phone signal mean? anybody got any clue?
shouldn't it be green/gray ?
in my phone whenever i have green/gray in the battery view the bar hardly goes down on idle but i see a big drain compared to green/gray when it becomes yellow even in idle
let me post a pic to clarify...
i was complaining about sudden batt drop on cm9 ics, i know its 2 diff roms but still the yellow bar got my attention in both pics...
just searched google and came up with red= no signal, yellow=very bad signal to no signal, green = good signal/full
bad signal makes the phone look for the signal in a bad way using a lot of the battery...
guess i found out why my batt suddenly dropped so bad compared to the rest of the bar...
id suggest flashing a couple of modems and testing how good of a signal u get with each and sticking with the one that works for u, if its a weak signal from the provider then find a better provider that covers ur place with better reception...
start from there and then if batt life is still bad search search and search... best of luck with ur phone...
@mazroui
in those 7 hours your phone should lost 9 - 10% of battery, but not more than 20 unused, what is process causing that usage?
for me: i charged phone before sleep, when wake up after 7h i had 20% left.
Android OS - 92% , rest for cell standby, phone idle and screen. Wi-fi was setup to sleep when screen is off. Better batery stats show that wi-fi was on for almost whole time
Cell Standby and Phone Idle using that much of your power means that the signal in your area is horrible and the phone is struggling to maintain a decent connection with the towers, this can drain a tremendous amount of battery depending on how bad the signal really is, the yellow bar means it's not optimal but there is a large degree of variation between the top end and bottom end of the yellow bar spectrum. Try a different modem or move your phone to an area with better reception and see if you still get this sort of drain.
Android OS is misreported by practically every Kernel because for some reason Samsung accidentally made Screen On add to the Android OS bar, so your Android OS usage is actually AOS + Screen On, for the most part high AOS usage can be ignored as a source of drain using the phone info battery screen, I would look elsewhere for the problem. Sometimes rogue apps hide their wake locks in another wake lock, for instance if you have facebook or many of the IM programs on your system, they poll their servers a lot causing a kernel wake lock called 'svnet dormancy' (in gb) or 'multipdp' (in ics) this causes a lock of 5s to ensure proper packet transfer, if your app is requesting packets every 4 seconds, then its essentially a permanent wake lock but may not be reported as the app being the source.

There is a defect with Android where good signal strength is mis-reported on this screen as yellow, even if you have 100% signal.
Until you go to About Phone > Status, just once. Then when you go back to this screen, it will start reporting as green if you have good signal.
I've tested this out on my phone, and confirmed it... try it out yourself.
I stopped caring about it, so I just ignore it unless it gets reported as red.

Signal in my area is far from perfection, but in same location, on GB i had 9% consumed over night, but not 70 %. I turn off GPS, BT, leave only wi-fi and data. And over night when nobody touch phone, screen is off.

If you look at the graph in the right pic you can see that the curve is less severe when WiFi is active, while this doesn't prove my point that its a network issue it does increase my suspicion that the issue is mobile data related.

Something is horribly wrong with that. Do a full wipe. If it still does that, reflash your firmware. If it STILL does that, maybe flash to a newer stock ICS firmware? Then as a last resort, you may want to go back to GB.

This guy may be onto something, actually. First thing you should try is flashing a different modem. THEN do all the stuff I said above.
EDIT: just noticed you're in Oz. Try flashing a T modem. Most Australian users report much better results with both battery and signal after doing this.
I've been using the latest gingerbread builds and I'm having great battery life, But I notice when I use AOKP or any kind of ICS rom my battery life isnt so great..
Is there a specific kernel you people are using? and What kernel settings are working the best for you?
Thanks!

Good news that you are not alone. Based on my premature calculation, only 10 out of 100 (that's 10% ) ICS ROM users have good - great battery life, meaning the rest is having worse. Mine is falling into that group. I never have great battery, only so-so and below average.
Also as Nick has mentioned, asking for which best is a NO NO here.
One might be good for me, doesn't mean it will be good for you and vice versa.
Try them all and pick one that best suite for you.
My 2 cents......I know you have read this several times - but battery life is really dependent on a lot of factors - your AT&T signal, rogue apps, data sync frequency, CPU governor etc. etc.
read Entropy's excelled thread on battery drain on this forum.
i tried out a few GB roms over the last few weeks and really did not notice any battery improvement over ICS.
Currently running cMIUI with xxkernel and it is really working out great as in the battery easily lasts for the whole day.
I remember when I was on stock GB I could go upto 2 days on single charge - but that may be due to the battery being brand new. I have read that the battery in SGS2 really degrades fast
I have 2% drain per hour when doing absolutely nothing, screen off, wifi off, gps off during 8 hours overnite.
While someone has reported having only 2% or 3% drain over 8 hours overnite.

Have you tried using "Better Batter Stats" to see what is causing the drain?
I have been using AOKP since Task brought it to us and I average 1% every two hours over nite.
Do you use the Facebook app? That sucker is hungry for your juice.

I got BBS v1.7 for a while, that was absolutely no help.
I installed BBS 1.8 for about a week. Based on their info, I got the "multipdp" along with some other things (such wake-lock) cranked up big time.
I read the Entropy thread, not much help.

Maybe 3G/H+ keep toggling for sync process?
I do use facebook! haha. and I havent used better battery stats

Have you tried using "Better Batter Stats" to see what is causing the drain?
I have been using AOKP since Task brought it to us and I average 1% every two hours over nite.
Do you use the Facebook app? That sucker is hungry for your juice.

I'd also recommend using CPU Spy in conjunction with Better Battery Stats to see if the phone is able to enter deep sleep.
I don't get as good as you. . .I average about 1% or less per hour overnight. But that's with wifi on, periodic syncing of 7 accounts, scheduled backups and cache cleaning going on.

I got BBS v1.7 for a while, that was absolutely no help.
I installed BBS 1.8 for about a week. Based on their info, I got the "multipdp" along with some other things (such wake-lock) cranked up big time.
I read the Entropy thread, not much help.
Note: Wifi is off.

My understanding is multipdp will show when apps are waking the radio to use cell data - each wake instance results in a minimum of 6 seconds of wakelock. Switching to wifi when you are idle "should" eliminate this wakelock.
I could be wrong here...dig into the known battery drainers thread from around the time the first ICS roms were being tried on the i777. There was some discussion of it...it is a renamed version of some other wakelock in GB.

That's what I said, "maybe 3G/H+ toggling".
I believed that if I left wifi on overnite, do nothing, I still had 2% drain per hour.
Let me completely turn off data tonite and see how thing goes.
errrrr I have a huge problem with my battery. I've been testing various ICS roms and kernels(aokp, foxhound, serendipidity, fluxxi Kernel, siyah 3.4.3.,Neak) and all of them with the exception of serendipity w/siyah kernel, drain my battery real fast.
Not really sure what the problem is but when I look at what's been using the battery its most of the time either screen (which is understandable) and android os? I went to bed last night leaving my phone at 100% and woke up to find it at 52%. When I looked at what was using the battery it displayed, 93% android os and only 3% cell standby??(btw Foxhound ICS, Siyah Kernel) Maybe I have to many things updating/syncing?
When I first got my phone, 2-3% battery drain overnight was one of the things that amazed me about stock gingerbread on the i777.
I've flashed alot of roms since then, and so far, no ROM can even touch that stat.
Can someone please check my battery usage for this phone, I think something seems to be draining it.
Over 10 hours I've seen a drain of 7% which doesn't seem TOO bad,
but could someone take a look at these screenshots too?
I mainly use WhatsApp quite a bit, and the occasional websurfing. At home, my signal strength is perfect. I'm connected to WiFi sometimes and my WIFI sleep policy is set to 'Never' too.
I've also underclocked and undervolted the phone, even with MagicConfig and I'm also using Supercharger V6. I don't think there's anything else I could do to improve the battery, yet it is still somewhat disappointing
At 50% battery life, it has 2 hours 20 mins screen time too
I'm using CheckROM V6, with N.E.A.K 1.4.2, conservative 200-800mhz.
Would it be worth upgrading to ICS?
Thanks in advance

Have a look at BetterBatteryStats thread here => http://forum.xda-developers.com/showthread.php?t=1179809
Install BBS app and post the stats file there to get propper help.
But 7% in about 10 hours is quite good IMO.
Here are some good battery savings tips => http://forum.xda-developers.com/showthread.php?p=16973603
I'm using combination like my signature says; performed 1 phone call and sent 6 SMS & 9h on battery = 100% at the moment. I think Siyah is the best for battery life
Okay, so i just installed CM10 (Dec 5 release) with no problems. Audio working just fine through both speakers. minor issue when connecting to bluetooth and wifi but reflashing fixed that. My issue is with the battery draining EXTREMELY FAST. Has anyone found a resolution to this?
Thanks, Jwallbanger.

first question, what do you mean by extremely fast? unless your phone is dieing in under an hr from full charge i wouldn't say its "extremely fast".. secondly there is a "discussion thread" located in the general section of the forums to talk about and find solutions to problems related to CM 10 found here, also have you checked your battery stats to see what is eating your battery away? weather its screen on time, cell standby, wifi or data... or an app.. there are several issues related to battery drain.. like if you have wifi on but not connected to a wifi location.. or having data on but in an area with no signal.. more information is needed but i would prob suggest to do a full charge to 100% wipe battery stats from recovery and then do a test from 100% to see how long your phone lasts with full usage and in full standby mode... then compare and see what is eating your battery life away...if not refer to the thread i liked earlier up in this post

Yes I mean dying in under an hr, dying while plugged in charging and all i'm doing is text messaging. And I've checked the stats, nothing different than when i was running speed rom. But thanx 4 the link to the discussion thread. maybe I'll find something there.

My suspicion is that Google now prevents the phone from sleeping normally hence affecting battery life in standby mode. However if its dying in under an hour that is quite drastic and I would suspect there might either be a rogue app running in the background (do you have the eBay app installed? I found that also contributed to awake times in cm10). Second question is how long did your battery last in speed rom? Were you getting at least 2 hours of screen on time? If you got less than 1 hour and 30 minutes of "screen on" time in speed rom with data not constantly on I would suspect your battery is failing as well. Good luck

Try a different Rom, is same experience, i recommend a new battery.. Battery can wear out over time..
No matter how many forums and threads there is no solution to be found for this massive battery drainage. stock rom vs poison with greenify, underclock, tweaks, lower brightness, other mods, and the battery is exactly THE SAME in both. Draining massivly. I have 60% now, 2 minutes ago when I was browsing in mozzila I had 66%. Also draining when screen off. I kept using the battery with same patterns for a lot of days, adaptive charging doesn't seem to help.. Any solution??
Go back to stock with fastboot and see how it goes.
There's probably a much more convoluted solution out there but it would probably be too much hassle.
Root Xperia X

Hi guys. Sorry for slow reply. I have tried going back to stock rom and other different roms. No difference. You see the weird part is that the battery lasts the same no matter what you do, stamina mode? same. Nothing running on background ? same. New thing happened: After the poison 7 rom in battery settings ann option "battery care" appeared. I turned it on to see what it does. Only after some weeks it decided to pop up when I plugged my phone to charge. It said something like "Battery Care active. Your phone will be fully charged in 5 p.m Tuesday (example) while it is still Monday 3 p.m. Should I listen to battery care and leave the phone plugged in for 1 day or not? (no matter if it reaches 100%).
This is a bit irrelevant but I am asking just in case: Is your phone too charging very fast ? I have the basic charger (not the fast charge) and I believe my phone is being charged a bit too fast

Me too i have the normal charger included in the box and it takes about 2 hours from 20ish to 90ish % if i plug it to a usb 3.0 port it takes about 1:30hr to charge from about the same
Battery Care is a nice app if you charge your phone overnight.It limits the duration of your battery charged to 100% by charging rapidly to 90% until a half hour or so before you wake up. To do so it needs to learn your charging habits first. Supposedly this prolongs your battery life. Attached an example. You can see it charges rapidly as well.

I see. Thanks for the info. I will try it if just saying. IF it can fix my battery problem. Probably it has nothing to do with it though

I agree it is unrelated. Since your battery problem seems independent on the rom, a few options are left: a rogue app that you always install, something related to your Google account, or a hardware problem.

Is it worth it to try going back to stock again and also unrooting? Or relocking the bootloader? I thought of an app but the only thing that it could really be are the google services , the play store. Messenger doesnt seem to drain much and makes a minimal difference, and with the app we mentioned above I didn't find absolutely anything draining the battery apart from screen and OS (it could also be more than normal)
I did all the trip concept-stock-concept and it seems it is an app right now I'm getting almost the day through and have 20ish of battery, it was easier in my case because I didn't unlocked bootloader or rooted, so might try a full clean reinstall to your phone

I'm currently also having massive battery drain(6% an hour) I tried stock rom, Posion rom and concept rom, sadly all with the same result. I use grenify & fordoze but somehow my phone wont 'doze'/go into deep sleep. I installed better battery stats to check out the problem. On a normal day(one charge) the sumery of better batter stats look like this:
deep sleep 7 hours / awake(screen off) 5.5 hours / screen on 1.5 hours
when i look to kernel wakelocks there is one that is always on top of the list:
bluesleep 5.2 hours 243 wakelocks
Also under alarms there is a suspect:
com.google.android.gms: 864 alarms 1/min
So there are some strange things happening on my phone... really wondering if you got the same wakelocks/alarms as I do
I use greenify and HEBF. Same story here, it seems like nothing changes with battery life. Crazy, only 1,5 hours? My average now is 3. I haven't checked the drainage when screen is off but I did notice similar drains to yours. I think we're in the same boat. I will tell you about the wakelocks, haven't looked into that yet

I've just received my phone for just one day. Backup my TA partition, unlock bootloader and use rootkernel tool to root my devices. I'm using the .331 version stock ROM. Just then I installed the ElementalX app on play store, and surprisingly found that the cpu frequency statistics show that the phone is always on the max freq. So I changed the cpu governor to interactive governor. Haven't test battery time yet. Hope you know this issue, if you have the same problem.

I'm wondering if you've check the cpu freq statistics. See my post above. If that's the common issue, than the stock rom maybe has trouble dealing with the cpu governor problem.

Actually I'm not lowering frequencies, I use EX Kernel Manager to tune the interactive governor according to this post
https://forum.xda-developers.com/nexus-5x/general/guide-advanced-interactive-governor-t3269557
After tuning the governor, it's about 4 hours SOT. Still not good compare to my Xperia Z3, but much better than before(about 2hr SOT)
