What kind of battery life are you guys seeing on the various ICS roms?
I tried out Turl's CM9, but I was only getting about 6-7 hours, which isn't good enough for me. I'm back to using Rocko's rom, but I was wondering what kind of battery life everybody else is seeing on ICS? And if there were any tricks that work in ICS to get better battery life.
I leave my wifi and 3g on, email connects every 15 min. moderate use, 1 to 1.5 hours talk, 75-100 text messages. little to no web surfing, no games, 30 min of pandora driving to work. my cell signal is low at work 1/2 bars, so i keep to the wifi. *keep in mind that for texting, majority of the messages during work time are sent back and forth through google voice, so i use my pc and never turn the phone screen on.
on Jokers CM9, pre 0.5.0 i would get around 15-16 hours.
i just flashed 0.5.0 a few days ago and just finished battery calibration yesterday. so far after calibration, im at 5hours 48 min and sitting at 91%. its looking very promising for CM9 0.5.0 build
I just unplug now at 930 and when I get off at six I am at 14 percent on jokers kernel I don't know how the other kernel is or if there are better solutions I would love to know too.

* remember to keep in mind that ICS is designed to multitask. It will run several apps, balancing them out and run smoothly. Gingerbread was not designed to be a work horse like ICS is. So with several apps running at once, unless you make sure to close out of them, they will still be running and chewing up battery.
Check to see what apps are using the battery power when you have ICS loaded, youll probably find that there is alot more going on at once then when running gingerbread.
13 hours 49m and still @ 51 percent on CM9. Mostly idle time, a hand full of texts wifi use and calls.

There's an option in the settings to limit the number of open apps. I believe it's under developer options. Would you think putting this to 5 would help this problem?

good find, i see stock is standard limit... i wonder what that limit is?
I have had mine selected at the back button kills all app. so if i long press the back button, it will be like a task killer.
I think the big trick with ICS is learning it. seams some people have great battery life and others not so great, but i really think you are on the right track with the running apps setting.
Note, i realized i have and auto killer that will kill all background apps once an hour. so least if i forget to kill something, within the next hour it will be killed.

Hi guys,
So for the past week or so, I've been noticing really bad battery drain on my GS2, and I think I have finally pinpointed the problem.
"BetterBatteryStats" has told me that there are 2 specific wakelocks running in the background, which prevent the phone from going to 'deep-sleep'. These are the "suspend" and "events/0" processes. They are on for hours, preventing the phone from going into a proper 'deep-sleep', and keeping it awake.
My question is, how would I stop these processes from running? I know for a fact that it is not such a common 'bug', because tons of people are getting >18 hours on their GS2 with moderate/heavy use, while I'm only getting about 10 with light/moderate usage.
So in short, why are the "suspend" and "events/0" processes running while the phone is supposed to be in sleep mode, and how do I stop them from running and draining battery?
Thanks everyone!
Well I don't have that problem so can't say. You should ask it on the BBS dedicated thread,
http://forum.xda-developers.com/showthread.php?t=1179809

This is the famous "Android OS" bug, which happens only on SGS2. Search the forum and you'll see quite a few threads about it. There is no solution, but keeping wifi off when not in use or setting is to sleep when screen is off helps quite a bit.

It's not only a bug on SGS2. I've been fighting this problem for quite a while on my Nook Color with CM7. Here's the thread I started.
hmm, I am having this problem as well, I'm used to my iphone, where i can use it all day and still remain above 50% meanwhile every time i pop the screen on my GS2 the percentage is down from last time. its horrible, very much considering going back, I love this phone, but this battery draining situation is out of control for me.. midnight -8:30 i lost 45 percent battery.. screen off..

well for me, installing the siyah 1.8 kernel has sorted it and my battery life is pretty damn good now.
Others will tell you its not fixed and the extra battery life im getting is a placebo. But all i know is i used to get 3 hours screen on time and lose 15-20% battery overnight. Now i lose 2% overnight and get 5-6 hours screen on time. If thats placebo then so be it.

hmm, ok, I will look into kernels, I am using an AT&T SGS2 so its a little different kernel wise. I have yet to find anything in my specific forums though.. just switched from an eperimental kernel to a stable, so maybe this will help
I think I just read somewhere in the Galaxy S2 forum that AOS isn't exactly solved on the .14 kernel (which siyah 1.8 is based on)..... it just merely not include suspend and events/0 into the Android OS count for the battery.....
Anyone can shed some light on this?

is siyah 1.8 better for battery life compared to siyah 2.1 or the newer one?
I tried 2.1, but I still have high android OS.
Using bbs, I see that suspend and events/0 is still around 1 to 3 minutes each day.
I have turned off:
Accounts and sync > background data & auto-sync,
Privacy > back up my data,
Location and sec > use wireless networks.
Any other advice?

Use a 2.3.4/2.3.5 based ROM such as CheckROM HD or Hyperdroid-Androidmeda with Darknight-Siyah Kernel.
I get 3 days of use if i keep data off . With Data on and normal usage i get on average 0.7-1% drop per hour compared to 3-4% of 2.3.3 ROM.I think it's a combination of kernel and ROM that solves the problem.
Earlier CPU Spy used to show lots of time spent at 800Mhz which is what android OS bug does. Now i see it spending 1-2% time in 800Mhz and most of time in deep sleep.
thanks for the reply.
now I am using CRv3.1.1 with speedmod 18test3.
but it seems that from day to day, events/0 & suspend are getting bigger and bigger.
do you know why?
I upgraded to KI3 a long time ago, and froze the hubs + wifi sharing / wifi sharing manager (i never even used the hubs anyways), and what do you know; my battery can now easily last me a LONG time, after 16 hours it still always has AT LEAST 40% remaining, and that is with a few hours screen-on time, data sometimes on, wifi usually always on! I'm extremely happy now!
So in short, for those of you with bad battery life, the least you could do is upgrade to XXKI3 or XXKI4 (they're pretty much the same thing) firmware/kernel. Even completely stock without root/frozen apps is A LOT better than any other 2.3.4 / 2.3.3 ROMs.
CRv3.1.1 is already based on xxkj3, and I have already frozen most of samsung bloatware.
However, I have just found out that kernel is an important factor in high suspends and events/0.
Now I use the previous version: speedmod 17 test 1, and suspends & events/0 decrease a lot.
Just a thread to see what the majority of people are choosing to run right now and which you have tested as well. This is NOT intended to be any type of a bashing thread, just please stick to what you've tested and what you've chosen to currently use.
As for myself, I'm running UnNamed from gtg and have been for a bit now. I've removed a few additional pieces of software that I didn't want and modified the battery icon but other than that, it's pretty much as is.
I've tested and have a backup of CM 7 and I'm planning to test Cognition next...
I am running UnNamed, I had a circle battery mod, but flashed the full update and have stuck with it as-is. I ran Cognition with no issues or complaints, but wanted the extended power menu.
Sent from my SGS II
I'm running Cognition as of yesterday. For a few days before that I was running a stock + root ROM.
I must say, my battery lasts sooooooo much longer since installing Cognition compared to Stock. I just now hit 90% and it's been off the charger (getting regular use: some idle, some web browsing, some pp installs) for about 6 hours now.
I love it.

I'm on Cognition and haven't tried others, yet. It works and as ROMs have appeared, I've pulled what I wanted from them. I get great battery life (3 hours of display time, but lately it's been increasing - yesterday I got 4 and today I'm on pace for over 5 hours of display ). I'm really interested in CM7. I hadn't tried it yet because I'm not convinced that it's bug free (which is important for me). What did you think of it?
I'm getting such poor battery life still, even after rooting and removing data hogs (AP Mobile, etc.), running BBS and CPUSpy to monitor, and turning off unnecessary sync. I'm thinking about moving to Cognition, but I kinda like Touchwiz's interface and the safety of running stock.

I liked CM7. I probably didn't give it enough time to make an accurate assessment of it as I liked the idea of trying UnNamed simply because I like the stock build as it is... minus the garbage bloatware and wanted the extended power menu. I'd highly recommend giving CM7 a shot though. I simply get each rom running and then do a full nandroid backup in case I want to go back in the future - barring any major improvements of course in which case I'll start out fresh.

I have to say that I was never much of a believer in Juice Defender but between running that program and doing a battery calibration with the app, BatteryCalibration, my battery life has increased quite a bit. I've still got Gmail auto syncing but I have turned off 'Back up my data' in Privacy and keep GPS off until I need it. Everything else is running as is. Oh and no Facebook or Words with Friends. I login to Facebook via Dolphin HD when I have to check it on the go.
Running UnNamed 1.0.3 and really like it. Clean, snappy and excellent battery life (yes, better than stock rom).

+1 for UnNamed.... love that rom!
Ive been on cog beta 4 for a while and it is perfect. Picked up DD exp kernal a few days ago and its still perfect. Perfect combo i guess. Battery life is amazing. After 15 hour days i am always getting 4 hours of screen on time along with playing music thoughout the day and few calls and messages data and sync always on.
I have yet to have any problems and gonna make this my offical "go back to, stable rom" when others start to drive me nuts. I would like to just stay on this rom and call it good cause its perfect but that never happens.

Wow.... That sounds impressive. I may need to give that rom a whir then.
Somehow, it seems over time battery life on ICS has consistently diminished. May try some things but this is stock rom, and really not a lot of apps widgets. Is everyone having this?
Example, Sunday I unplug it at noon, and by 7 its at 4%, made a few calls, say 3 under 5 min. Used navigation some, texted some, and a bit of fantasy football app. But that seems below reasonable expectations.
Widgets: 1 weather, Tim Hutt ICS calendar, SiMi Clock, battery & Weather(lockscreen), Widget Locker, Google Music. Launcher: Apex pro.
Did a bit of surfing and didn't see much around stock ICS (could have missed it)

I'm on the US AT&T stock ICS. Have not tried any roms.
If you upgraded via kies or OTA...the chance of a corrupted flash is high.
I'm not saying that it is, but we have had several reports of failed OTA or kies upgrades to ICS...
The only good fix is a re-install of the build...
I would go to samfirmware.com, and push the rom to the device again, and then test the battery life.
this would not be the first bad rom image we have seen from the upgrade.....g
And remember, it takes 3-5 days of normal usage after a fresh install, for the dalvik cache to build, and for the device to "settle" before any accuracy can be measured...g

If this is the case, should I try something like a factory reset then reinstall? I initially updated via Keis.
What is typical battery life on ICS? I recall I got the note right before going to SXSW and it would run from 8am to 11pm with solid use and maybe a 10-20% top off somewhere in the day. This has given me serious cell phone "range anxiety", even bought a external battery to address it.

Best screen on times I've seen are ranging from 3-4 hours, and overall battery times are going 18-24 hours...
Now mileage varies greatly between users, and i'm running ICS as well, and since 6 a.m. today, I've used 14% battery in 7 hours...
I've made 2 phone calls, sent 3 texts, and messed around with settings for about 30 minutes...
It does sound like you may have gotten a dirty flash image...but it's so hard to tell, unless you get random freezes, boot loops etc.
But the stock ICS battery life was horrible for me........g

It boots and actually runs fine. Occasionally cell standby chews the battery out of nowhere, andriod os and phone idle too.
I pulled it off the charger today at 9am and as of 2:00 I was at 68%. Checked email, messed on flipboard while making coffee, updated a few apps. Checked traffic. Mostly just sat on my desk.

Understood ...
Fortunately, the note is painless to use on custom roms ...
With the ATT version, you simply push a custom recovery to the device via Odin, then download and flash the rom.
No root needed. And if you don't like it, you restore the stock nandroid backup and presto...no more rom.
Root is very nice though, as it allows sooo much more control ....g
Extra Batteries, their cheap and totally worth it just make sure you get a wall charger too
I've pretty much given up on eking out more battery life since it seems universally bad.
A bit more than 4 hours screen-on time seems to be the limit without setting the screen to ultra dim.
Standby seems entire dependent on my signal strength and whether I have LTE enabled or not. If it's strong, 24+ hours isn't unreasonable.

Well, yeah screen destroys the battery. After ICS it seems as though they cranked up the brightness and contrast. Or is that just me?
Hey Folks,
Is there a Download for AOKPCB Rom? Because the link in the thread is down :/
Or is there another good and stable ICS Rom with low Battery consumption and cool design ?
I haven't seen that port in a while, so I'm guessing it's been discontinued. I personally believe CM10 is more stable than CM9/leaked ICS. Try EPinters CM10 in the development section. Aside from lack of HWA, everything works.
I have seen the PCB keyboard around, maybe there is also the theme available. Couldn't hurt to try as CM10 is themeable.

I'm running epinters CM10 at the moment but I have bad battery conditions with it.
I get about 7 hours of heavy use with constant screen on. That includes playing music in car, streaming Pandora, lots of WiFi browsing, youtube, gtalk, texting and few calls. I have mine set to 2G only to get better battery as don't call much. Sync is set to standard values. Normal use gives me about 14-15 hours.
There was a version of CM10 with HWA that had terrible battery life. Also, I'm not too sure, but I believe there was a version of EPinter that gave me bad battery life (5 hours or so). Think three earlier ones were better, but I'm on 11-17 and it fairs okay.
If battery life is of concern, I'd stick with GB (MROM is great, can get 18 hours with normal use). I know it's hard to go back once you've experienced ICS/JB but at least you'll have a working fingerprint scanner. =P
Edit: Forgot to mention, I have a lot of the 'useless' apps disabled. I also use LBE v4 to prevent a lot of apps from auto-starting. I'm not sure if it helps, but the placebo effect does. Seems to boot faster, save memory and battery. (less background processes to manage, I guess)
Edit 2: Here's a link to the PCB theme, haven't tired it personally as I prefer system theme.

Lately my battery usage in battery monitor widget has been going over 1000ma multiple times a day. In fact this has been the case both at the beginning of my Rezound's life on the first firmware, and again now.
At one time in between I used to never see it go over at most 700ma, and experienced reasonable battery life too. Usually I saw about 70ma to 300ma usage. This was with several different roms on the same firmware. I think it was the first or second ICS firmware but I don't remember for sure.
I'm starting to think the firmware a few versions ago was better on battery life. What do you guys think?
I was running GB with the old firmware up until just last week. I was averaging about 20 hours on a full charge with 1-2 hours of screen on time. The rom ran great and the only issue I really had was my 4G would cut out completely whenever I tried to play Youtube videos....
Last week I updated to the latest official ICS global rom with the new radios and firmware, and my battery life has gone in the toilet. I'm averaging about 15 hours on a full charge with the same 1-2 hours of screen on time. My phone gets MUCH hotter when just doing simple things like browsing the web, often getting above 100* F. On GB firmware I was usually in the mid 90's unless I was gaming. This is with the stock kernel. For the past couple days I've been trying FunkyKernel with some under clocking and undervolting which has helped the heat but not so much the battery life.
I'm kinda pissed and strongly considering finally going S-OFF just so I can roll back to the old firmware.
I actually think I had the best battery life on the first ics firmware, but like I said it might have been the second one. I don't remember how many there have been, but I have done all of them.
This latest one just seems to suck down power.
Anybody else have some input?
I just recently updated to the official global firmware and am running Rezone Redux with Funky 3.7. I'm not doing any undervolting and the only change I made to the frequencies was setting the min to 96 and the max to the stock 1512. With my extended battery, I'm averaging around 4.5 hours of screen on time, which is actually about 30 minutes more than I've ever gotten out of this battery. Then again, I keep my data, WiFi, and GPS off at all times unless they're needed, screen brightness at 13%, I'm using an app called Greenify to hibernate certain apps (not freeze, there's a difference), and I'm using the Wheatley governor. I'm very happy with this setup.

So maybe it isn't affecting your as much because you keep your radios turned off. I also use greenify and it has definitely helped.
I might go a day with my mobile data enabled all day and see what happens. I got into the habit it of toggling my data off about a year ago. The only reasons for me to keep it on would be weather updates and Facebook notifications, neither of which is really important enough to me to have them refresh automatically. I don't use push email or anything like that, either. I suppose it would make a difference for someone who needed instant email notifications and such.

I also keep data off most of the time unless the phone is plugged in, but still, battery just hasn't been the same since the latest firmware update...
I want to update you guys on my battery issue I thought was related to the new firmware. Every rom I had used since the newest firmware release was horrible on battery life. Using battery monitor widget to monitor power usage, I was often seeing over 1000ma usage many times per day.
I recently installed neo's infection 2.9.1 which uses a stock kernel based off Flahalf's work. My extreme battery drain is gone! The highest usage I have seen in 2 days is around 500ma, and normally it is 100ma or less! Not only that but this Rom is smokin fast. It feels like a new phone!
And it fixed wireless tethering! I'm so happy and thankful for the awesome work or devs have been doing. Thanks guys!
Unfortunately for peeps like me who enjoy gaming on their phone, the JB roms aren't all that great. Graphics performance is generally poor....
Maybe you should give it another try. I just played some shadow gun and the performance was fine.

I have looked for neo's infection 2.9.1 and find it nowhere. Its getting late so maybe im just tired. But i need a fix for battery also.
Thanks for any help you can provide.

Then you must not have looked very hard, it is here on XDA in the Rezound Original Development forum, along with other amazing ROMs like Tron, Beanstock, Liquid Smooth, PAC-Man, etc.

Well I thank you for the post and help I keep forgetting there are two separate forms for DEV now which i really never understood why they made two.
Thanks
