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.

Hi there.
So I flashed Cyanogenmod7 to my Optimus One
I'm very happy with it, however, there's a problem
On official froyo and 2.3.3 official gingerbread, i had the data connection ON and wifi on,too.So whenever I left the house, it would switch to data.And it wasn't on 2g,it was on HSDPA. Anyway, the battery consumption was barely noticeable,especially in standby mode.
However, if i do the same thing now, on CM, the battery drain is enormous
Wifi does not consume a lot, but whenever it switches to mobile data, the battery consumption is 10% / HOUR in IDLE mode, using the Smartass governor 245-600MHz, making the phone useless. And this is the consumption in standby mode...when I use it it's a lot worse. This problem makes me unable to use the mobile internet without returning home with a dead phone.
Is there a fix for this? Does anyone have the same problem?
Yes, i have the latest version of CM7, for my model,p500. Is it because of the old baseband?
Thanks in advance for any help
i encountered this for the first few days when i flashed to CM7 too
battery drop so quickly even when its at standby mode for 8 straight hours.
but after using for weeks, the battery begun to last longer, can last up to 2 days with light usage (some texting and tweeting)
im getting minimum of 4 days battery on cm7 -.-
Try this
1. Charge your battery to 100 percent.
2. Reboot into recovery and wipe battery stats.
3. Completely discharge the phone till the state it switches off.
4. Charge again.
Maybe it will help.

@OP: Which CM7 version? What kernel?
This is not usual.
I'm getting few days with CM7. Try calibrating the battery with Battery Calibrator from the market.
I already calibrated with the app from the Market
Charged to 100% ,Calibrated,discharged to 0%,then fully charged.
I did this twice.i dont think this is the problem.
I did a test :
Yesterday,when I first saw the problem,i had data enabled.I got 10 hours of battery life with the phone Idle (locked,yes.)
Today, i didn't enable data.I had 99% battery after 2 hours of idling. I guess that's normal.
So, i already know the problem. the data connection does this to the battery,but why?... as i said,when I was using the official froyo and gingerbread,i had both data and wifi enabled and i had absolutely no problem with battery drain...

This is called battery calibration.Whenever u flash a new rom,u need to calibrate ur battery so that it wont show u the stats of ur previous rom.If u dont wipe battery stats,sometimes the phone may switch off fue to low power at 15-20% or strange things like virtual increase in battery % by 2-3 %.So it is required to wipe battery stats,so after booting the phone,a new battery stats file is created and it wont give false info.

There's no need to completely discharge a Li-ion battery, it can in fact damage the battery.
Proper steps:
1. Charge your battery to 100 percent.
2. With phone still plugged in, reboot into recovery and wipe battery stats.
3. Reboot phone
4. Wait for phone to completely boot up then unplug.
5. Calibration complete

I checked for apps that consume internet.I don't have any.Facebook would be one,but that's all.
I read something about the older versions (official ones) of the firmware using something called NETMGRD to reduce the battery drain caused by the APN being on..
what do you guys think about this?
And also,since you asked about the kernel :
2.6.32.42-franco.kernel.v18
Cyanogenmod 6.5.8
If i use 2g continously i get batrey lyf of 3.5 hrs..
Is this normal?

That's pretty outdated kernel. Flash a new one.
I get good battery life using the 2x Battery program that cuts off the 3G data when the screen is off and opens it at a set time (every 30 mins on mine) to check for email etc instead of constantly when the screen is off.
One of your major killers i see is the constant WiFi, with it and GPS if your not actively using them turn them off.
---------- Post added at 08:51 PM ---------- Previous post was at 08:47 PM ----------
Forgot to add, the rule of thumb is anything that uses a hardware component uses battery power.
GPS
Wifi
Cell Radio (2g,3g,Phone)
Screen
Vibrate motor
Speaker
It takes power to make those work so the less you use some of them the longer the battery lasts.
Anyone that drives at night knows the effect of turning on the wipers, the radio, the lights and the blower fan on high to clear off the windshield and seeing the voltage gauge lowering from the heavy voltage draw.
I have updated my S2 with the official ICS. My battery life is now so poor I struggle to get a full day's use. Before the update I would get about two days with moderate use. I have read that the battery life should improve with ICS update. Can anyone explain this and give a solution as it is very frustrating.

try some batt monitoring apps from market and see whats draining ur batt and resolve the same either by force stopping those apps r deleting them if u find they r batt drainers
and also for ICS it requires at least one r 2 recharge cycles for things 2 settle down

Samsung Official ics will always be a battery eater.
Suggest you to root your phone and install a custom rom like wanam/slim etc. These will remove all unnecessary bloat wares giving u better battery and performance. (Do remember to read all the necessary info before u root).

Have you tried BadAss Battery Monitor?
imho: too many running services in background.. try to kill/freeze unnecessary apps(use link2sd), but most important thing is it seems that current ics is not optimally written/optimized, most kernel can help minimize this effect (but minimal e.g. speedmod)... if you can bare with this condition you ics is for you.. but if you are expecting an optimal performance of your sgs2, you should consider reverting back to gb ..
If you wish to remain on Stock Rom, please root your phone. CF-Root kernel here

Then use Titanium Back to freeze unwanted apps which drains your battery. List of applications safe to remove here.

Deepsleep with 42% is far to little
Find out, with process drains your battery.
Use BetterBatteryStats und look for kernel wakelocks after display is 1 or 2 hours off.
I had the same problem a while back and battery would go down to 20% in about 5 hours. Did a factory reset because when I upgraded, I didn't wipe cache. I read somewhere that old gb code could cause issues.
After the reset, phone works great. I get to 50% battery in about 13 hours. If you can, give it a shot. Of course, back up paps with Ti, otherwise reinstalling them is a *****. :banghead:

I'm quite satisfied, after first cycles now with stock Italian LPF and Phenomenal 5.4 Medium Kernel I have very satisfing results (I forgotten the phone on this night, in 5 hours it drained at least 1-2% of battery).
In normal operativity I'm on 13-16 hours with 1650mhA battrey.
Thanks will do that and post results for further help.
Battery life has now improved to about 15hrs since taking the battery out for recalibration and putting it through a few charge cycles. But this still feels to low.
Ps deepsleep still at 42%.

oooor you can downgrade to Gingerbread and get a custom rom/theme for that awesome ICS feel and at the same time get awesome battery life
I backed up my data, did a factory reset, restored my backup, charged the battery and now the estimated battery (@ 64%) is about 30 hours. So it seems my battery problem is sorted. Holding thumbs!

I suggest i apply all the Tweaks as possible first, secondly install a cok kernel like Siyah, then see if there's any difference

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.

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,
I've been flashing roms onto my phone for months now and what I've realised is that the battery life is always awful. I hardly ever get past 10 hours, with just 1 hour of screen on time as my battery drains in stand by. I've tried cm7, cm9, perfect galaxy, miui, stock and many more, but my battery life always seems to be the same. Currently I'm running cmiui (latest version) and still battery is draining very fast. I read about people having amazing battery life on a daily basis.
My current battery life drains by 1% every 2-3 minutes of screen on time and about 5% of drain when in deep sleep or stand by an hour, sometimes even more. I use betterbatterystats, cpuspy and gsapp to monitor my battery but nothing suspicious occurs. Usually my 'awake' time tends to be 50% higher than my screen on time according to betterbatterystats, however all the wake locks tend to be kernel related. Changing kernel doesn't change this either. I've literally tried everything, installing several kernels, modems and calibrating my battery every time I flash a new rom.
Also what I realised is that my phone frequently overheats near the camera and even sometimes reaches 50°c.
I would appreciate it if anyone could help me on this topic. It is really frustrating that I cannot get through a day of even light use of my phone, which makes it almost unusable as I'm always concerned about my battery. I've also tried several batteries, so the problem doesn't lie with the battery.

Everytime you install a new Rom/Kernel you have to wait for it to settle down (About 2 Charging cycles). If I flash a new Rom to my device Batterydrain is very high too at the beginning. What you can do is install a Rom and a kernel which supports undervolting and underclocking.
I use Resurrection Remix ICS 2.6.1 with the Siyah 3.5.2 Kernel with this Voltage/Clock settings (LESS AGGRESSIVE UV VALUES with -50mv and not -75mv undervolting):
http://forum.xda-developers.com/showpost.php?p=26755476&postcount=850
With this settings I get 16 - 18 hours easily and with about 2 1/2 -3 1/2 hours of screentime and also about over 4 hours of listening music and doing other stuff of course.
Everytime you undervolt/underclock make a Nandroid backup!
Thanks, I've heard about the battery charging cycle before, I'm new to cmiui, flashed it yesterday but I've had cm9 on for about two months and the battery life was horrendous. I will try the undervolting and see how that goes

get a 2000 mha battery over ebay
I have been used 2000mah battery, miui 2.8.3 + siyah 4.0.1 kernel, no serious battery life issue :good:
I have a 1800mah battery, its actually not that much better than the stock battery, but doesn't the 2000mah add extra thickness?

Yes but it`s no thicker than your speaker part of the phone.
I'll have a look at it, I've re calibrated my battery this morning and ismt half bad so far. Its 9 o clock now and sill have 38% left with about 1.5h of screen on time, phones been unplugged for about 10 hours. I've used the undervolt setting as suggested but still loose about 4% of battery in stand by each hour. On comparison my mums iPhone 3gs looses about 1% every 3 hours. Surely the android battery isn't that much worse

If it occurs with every rom you have could it be app related, wiggets or syncing too frequently?

That's what I thought but I've analysed my apps with betterbatterystats and gsapp, nothing suspicious came up and wakelocks are always kernel related. I've tried several kernels as well

Get cpu spy from the play store to see if your device is deep sleeping. Also, you can try 1900mah anker battery. I got two and a charger off eBay for $25 can. Definitely a good deal

Mysterious indeed, all I can suggest is what I would try which is to give a custom rom call slim rom a go after full wipes and format system. Its a stripped down rom and always gives good battery life as it's so lean. Hope you find a fix soon all the best.

maybe your battery is bad i bought a great 2500mah battery on ebay http://www.ebay.com/itm/2500mAh-Ext...ccessories&hash=item4ab6494de0#ht_2481wt_1163
that combined with the rom OLLO MONSTER gives me awesome battery life
I might have to invest in a new battery. As I said before I've upgraded to a 1800mah battery and using that but the difference is minimal. Also I have CPU spy and it goes into deep sleep quite a bit, awake time however according to betterbatteystats tends to be about 30-40% higher than screen on time. And i'll try the suggested rom after I've given this one a few more days on the undervolting

For BBS, anything over 1% is something that needs to be fixed. Keep in mind you need a good sample time (like over 5hrs)

Hmm looks normal, I would get the 2000 mah Samsung Original Battery because 10 hours and already on 38% battery is not so good in my opinion.

I've taken a few screenshots of bbs, somehow the kernel wake lock is completely empty which is odd
Also I only need the battery to last about 15h with 3-4h of screen on time to get me through the day!

Well that looks decent. Do you have key press sounds and lock screen sounds off? that could cause audioout_1 wakelocks
