As I see, your rom is 2,2 android? Try to read this topic http://forum.xda-developers.com/showthread.php?t=1185241 download the BetterBatteryStats app and check which process or wakelock is draining your battery. If its DataTracker-FD wake lock, than it seems that 2,3 and 2,2 android is having Fast Dormancy issue..
I'm experiencing heavy battery drain. I installed betterbatterystats and found out that AlarmManager is keeping my device awake. What to do? Running CM7 6.6

I can say just by looking at your screenshots that u run too many background apps and widgets... try removing all of them and watch your battery drain.
I used to experience high battery drain and that was because the miriad of little apps running in background. They don't let your phone sleep, even when the screen is off.
Now my phone's battery lasts for at least 40 hours and that's with heavy Wi-fi, some 2G/3G, some gamming and music. About 1-2% battery drain per hour on idle and that's because I still run some widgets (and gmaps). Right now it's marking 53 hours and still at 27%, but thats 'cause I'm home on my PC.
Edit: Oh! Also just noted u use franco.kernel 18.1... get rid of it, it's been reported by many users (me included) that it causes battery drain. Get back to 18.0.
I could revert but I forgot the changes from v18 to v18. 1 " anyone can kindly tell me?

Can you please let me know what are the settings you've on your phone? I have Mik's CM7 with Franco's kernel v18. OC 748/245 Smartass. Auto-sync turned OFF. Only 2G networks. Brighntess 40%. Not having a lot of apps. Set Auto-refresh to "No" in apps like Facebook and Twitter. So basically no app tries to connect to internet unless I turn them ON manually. Only Google search, digital clock and power control widgets. No gaming and almost no music.
With all these I'm able to get around 30 hrs of battery life with moderate usage and 20 hrs of battery life with heavy usage, mainly Wifi. How do you manage to get so much battery life? Can you please let me know your configuration and the other settings as well?
Thanks in advance.

That's unnecessary and useless to downgrade. Mik's 6.6, franco's gingerbread kernel and scary governor, you get unbeatable battery life. Unfortunately you get some bugs too for now but mik's back and andy's working on his new rom so soon you'll see those bugs squashed.
try use v18 bfs franco kernel
So, I went to sleep at full charge, took it off the charger to see how my drain was....I woke up 6 hours later and it was at 64%. I took a look at partial wake locks and it looks as follows (I can't upload .png from my phone)
RILJ (Dialer) 205s count 2178
juicedefender 3019s count 1570
Alarm manager 1543s count 1320
Google services event log also has a pretty high count. I ran the "battery fix" and all that jazz,recalibrated my battery,not sure why drain is so terrible?
Could someone please help me out?
I am running cm7 with faux 0.2.0 1.3 kernel. I have it undervolted and profiles so it never goes above 1ghz unless on ac charger. (456 when screen is off)

I'm not sure how much it helps you with your issue, but for me JuiceDefender works very well. I would otherwise have a multitude of data sync apps such as Gmail running, and this limits it while periodically enabling sync.
Start tweaking what apps are using data and the battery life will be better.
I have had a problem the same where I am not so sure juicedefender is helping because I tend to set my phone on the desk when I do homework and the screen comes on after I put into sleep mode and then no more that 5 seconds later it turns on at about 25% screen brightness then jumps to 100% them dims to 25% then goes off, all in a matter of between 10-20seconds. I loom at the battery use area in settings and standby is at least 40% & display is right under and idle is next. my settings that I think may be causing this are the mobile data where the autosync is set at enable (in juice defender) & I tried ping but it does the same thing. I just want to know why the screen comes on ever 5 seconds. I don't know how to contact the developer to try and resolve my problem. I am actually on a thunderbolt but that shouldn't matter. I just wanted to reinforce that "i'm not sure juice defender is working as I get about the same battery life".
Xoom Xoom
I get double the life out of the same roms. I'll try a rom for a day then run juice defender and get a day and a half. Depends on how you have defender setup. The only thing I don't like it doing is disabling my wifi as It sometimes won't reconnect back unless I manually do it. I think setcpu is a joke though. I had it set for 216/456 at screen off and it was running at 1200 for 1/2 the time it was supposed to be asleep. Then whne I opened it up...(Battery less than 50% stay below 1000) and the screen booted up 1300. So to me it's an extra service I don't need.
JD has always given me more battery life on any rom that I have tried.. I recently got rid of it and am trying out GreenPower. so far GP seems to work a bit better than JD. I get a bit more life out of my batter than JD gave me.. try green power out if JD is not cutting it for you.. GP seems a bit lighter as well.. so, could be overall why get more battery life out of it..

Juice Defender seemed to do little to nothing for my phone. I got rid of it and my battery life remained the same. I can't say the same for everyone else but what works for you might not work for the next guy.
All I'm simply saying is give it a shot and test it out religiously before you make a decision to use it or not.
Works for me another good thing to do if you use set CPU underclock the hell out of it when the screen is off not using it so why not

My setCPU profiles are as follows:
CPU > 62.0c 456/216 (Priority 100)
Screen off 456/216 (96)
In Call 456/216 (75)
Charging AC 1300/216 (74)
Battery < 20% 608/216 (59)
Battery < 10% 456/216 (54)
Phone is otherwise capped at 1ghz
I have JD configured to run my syncs once every 15 minutes for 1 minute. It is also disabling mobile data while the screen is off and wifi when inactive for 1 minute.
Not sure what else I should do here? Should I re-flash CM7 with the battery @ 100%?

Install the battery calibration app and see if your charge at 100% shows 4000mV+, if it doesn't, that means your calibration is off and you need to search for juggernaut's battery thread and follow the instructions on that to fix your calibration.

Barely saw any gain using JD...only used it on my Dell Streak though. The atrix will go 2 days if I need it to so I don't see any need for JD.
I m using JD for nearly 2 years now and I have to say that it DEFINITLY improves battery-life - just by letting it switch off your 3G when you don´t need it you save a lot of juice.
When I still used my Captivate as my DD, JD helped alot. With all the firmware leaks I was reflashing my phone all the time and constantly testing different kernels/roms/apps for battery life.
On my Atrix, it hasn't seemed to help nearly as much. Not sure why... SetCPU with faux's OC/UV kernel has boosted battery significantly though.
I got lots of wakelocks using it. For me it's better to turn off data manually.

+ 1, it instantly topped the wakelocks. I thought I'd give it a go & bought the full version; un-installed 6 hours later. Maybe it works well on cm7? I'm on Nottach's Dark Side.
Back to good ol' green power.

Switched to green power
and now I get at least 12 more hours versus juice defender...crazy!
Sent from my MB860 using XDA App
Interesting. I'll have to try green power. JD said my battery multiplier was 2.10x when I used it. It could just be making that up though. I got 28 hours of life from the atrix and still had 40% battery left (moderate usage: frequent texting and periodic data+wifi usage, I think a 20-30 minute phone call too)
I swtiched to green power. Didn't notice much of a difference in battery life, but Gp is certainly a lot easier to use.
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?

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.

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.

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

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

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.

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.

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.
Hi guys, I have a problem with cm10 based rom (PA2.53), cpu doesn't go into deep sleep when it is supposed to. It does go in deep sleep, but for very short lenghts of time, during the night (with quiet time enabled and jd plus) i lost more than 10%/hr (from 100 to 20 in little more than 6 hours idle), I checked cpu spy and of 6 hours idle little more than 1 was in deep sleep and 5 at minimun clock freq (134), there's no app keeping the phone up as battery was drained for 70% by android os (which also shows cpu awake for more than 5hrs).
Any suggestion to fix this? I know battery drain is "supposed" to be high on jb, but isn't over 10%/hr in idle a little too much?
Using mesa 2.3, smartassV2, min 134 max 1200, jd plus, startup manager and fast dormany tweaks in init.d...any suggestions to fix this problem?

PIMP MY ROM.search for it on google.and use aroma version,it has more options.works perfectly on cm10.lagless and after night got 1% battery drained.

I already had that, the fast dormancy tweaks come from there, also installed every battery tweak pmr has to offer, but still draining like hell. I checked better battery stats and there are no unusual wakelocks...

I tried a last resort solution and it seems to be working (not too stable but better than before) I completely discharged the phone, recharged it fully while shut down and battery consumption seems to have improved. I lost 6% right away when unplugged it from charger within 30minutes, but now i have 12.30h running on battery and it's down to 84%, so aside form the 6% that drained immediately from 100 to 94 the rest seems to be keeping up pretty well. I'll keep an eye on it though as it seems to vary from time to time...In two days new pa and new fxp should be out, I'll see if that makes anything better...
Thanks for reading and for the replies so far
I think i found out what is causing the high battery drainage, it's the mobile data connection. For some reason JD (or the system) can't shut it down when phone is at sleep. Last night i switched mobile data off and in the morning i had almost less than 0.5% drainage, as soon as i turned it back on battery percentage started dropping at sight...
Battery Calibration
Download BatteryCallibration app from the market and follow the steps given there..
Helps me everytime i have a battery issue...
HIT THANKS IF THIS HELPED
Thanks for suggestion but that doesn't help, i used zepps die hard calibrator before, but it's not a battery problem. Random processes at random times will keep the cpu running when it's supposed to sleep, that's what's draining the battery..
Perhaps an app is polling the net too often, facebook anyone?
Xperia mini (smultron), CM10 150, Xtended kernel + rom
No i have app control which prevents any unwanted things to start-up automatically (and fb is on the no-fly list )
I think i kinda sorted it out, what causes the problem is thethering. When i disconnect tethering according to phone wifi and data are off, but in truth they keep staying on. I shut tether off and can still see my hotspot from pc even if wifi is completely off on the phone! So it's wifi and data which keep staying awake (even with screen of for long periods of time) and slowly drains the juices.
