Love everything about this ROM except for the battery life, using KK3, dyanmicram's 99tweaks, app_process and system_server.
Why does my batter drain from moderate use in like 11 hours?
What kind of background apps or services are you running? What CPU governor is your kernel using (you can check with Voltage Control)? Is the phone draining quickly in standby, or only when you're using it? If it drains quickly in standby, use CPUSpy to see if your phone is going into deep sleep (otherwise you might have something causing wake lock). What kind of reception are you getting with the KK3 modem?

Sorry for the late response! Just reflashed CM7 after being disappointed with other ROMs.
Now using CM 7 11/21 build, USAS v13, 99tweaks, KK3 modem
Kernel using conservative governer. cfq I/O Scheduler. 100-1200 MHz
Phone seems to drain too much on standby.
CPUSpy says it is NOT going into deep sleep. Can't pinpoint any app preventing it.
Getting mid-full reception 3G/H+ with KK3 modem.
Edit:
Killed all processes, restarted, cleared out my voicemail (was that the key?), now i've entered deep sleep.
Spare parts says the "partial wake usages" are Dialer, Android System, Media, UID 10060, and a few other things that are practically nil.
Will keep yall updated if this actually worked, going to reset timers in CPUspy, put phone into sleep for an hour and see how much of that is deep sleep.

Has anyone else been using CPU Spy to monitor Deep Sleep? I haven't once seen my phone going in to Deep Sleep. Anyone else?
Yeah I used it since yesterday. I've frozen a ton of bloatware via TB and it went into deep sleep for 7.5hrs last night while I was asleep. I'm seeing a crazy amount of different CPU speeds in there too though. Very odd.
I actually removed all the damn bloatware instead of freezing them. But then I added my own apps that I normally use. But I think I have finally weed out the damn app that is causing my deep sleep issues. it's either FriendCaster Pro or Google Music Beta...
I gave it a try yesterday when I first picked it up. Seems to either idle really high, or low depending on what your doing. Hardly ever used the mid range cpu frequencies.
yes! Once the source code can be.... had.... Kernel development would begin. As anyone have seen using CPU Spy, the governor either MAX out the CPU or just lower it to the minimal, it "rarely" stays in the middle. With some "tweeking" how the CPUFreq works we can probably save battery

I have been using it for a couple of weeks now along with Antutu CPU Master. After charging, I usually reboot my phone and deep sleep kicks in. I use Antutu to lower the CPU speed to 192 mhz.

Are you having any problems with Antutu keeping the setting at 192, after I reboot my phone Antutu keeps changing the low setting up to 384? Yes I have it set to apply on boot. I sent the Antutu devs an email a few days ago asking them about this, but no reply?

I thought this was the deep sleep issue that people have with certain chargers?? plug charger in and let screen turn off then turn screen on and unlock, then unplug charger. Check to see if it goes into deep sleep then or just reboot the phone after charging....

Hi, first to defend myself, I did search and found that everybody says good things for every kernel. So every kernel is best for Stock ICS?
I got confused. Yes I'am total noob and recently learned how to root and flash custom rom's.
I just want to hear your opinion for best kernel running on Stock ICS.
I need kernel that is good for the battery but also snappy for the system. I don't play games and I use my phone for calls, reading news, working on excel files, google maps, mail and taking pictures.
My phone is Nexus S GT-I9020T on Wind network.
IMO ezekeel kernels
Has lats of featured including voodoo color

Thank you. Is this kernel stable?
Im just trying to set it up as we speak, will let you know how stable it appears once I figure it out
Stuck on trying to flash an unsecure boot image at the moment.
*shrugs* The stock kernel?
Unless you want the functions third party kernels bring to the table, I don't see a good enough reason to swap the stock kernel for another.
That's what I was thinking. With Glados kernel I had problems with restarting after the screen turns of, also with Matr1x kernel. Also I read that there are restarting issues with IMO ezekeel kernels. Yes I know that probably the most stable it's the stock kernel, but there is problem with battery, I had more juice with GB and CMD 7. That's why Google paused ICS update on Nexus. But probably I will stick with Stock Kernel because for me it's better to have less battery for now instead random restarts. I hate when my phone it's not in perfect state.
Just managed to get ezekeels CFS on there and I get the reboot bug after going to standby.
Looking for updates but the thread is huge. Yet to try BFS.

You can try and turn off deep idle for your reboots.
Solves the problem 99% of the time (totally made up stat that could actually be true)
But actualy that function (deep idle) it's the most impotant thing in the kernel. It gives more battery time. Other thing are just fancy. More battery and no hickups, I dont need overclocking because I dont play games.

Deep idle gives more battery time under certain conditions (screen off but not completely idle, playing music for instance). It won't really give you more battery time if your phone is actually idle with the screen off.
But according to this http://forum.xda-developers.com/showthread.php?t=1297535 I understood differently. Maybe you are right, I'am still noob to all of this.

The first post that you linked actually just confirms what I said.
Ezekeel said:
Since this is just theory and Morfic noted that his experience seems to indicate otherwise and that limiting the CPU frequency does actually decrease the battery drain, I put this theory to the test and logged the battery charge over 10h of FLAC playback in Airplane mode with the screen switched off.

1) Playing FLAC (not idle)
2) Screen off
Pre-requisites are met.
So as I understood the battery consumption is reduced only if you listen music, because you can't do anything else when the screen is off. And the deep idle is working only in standby mode (screen off).

Deep idle only shows savings if there is tasks running while the screen is off VS the same situation without deep idle.
So for someone doing commuting (like simms22 for example) and listening to music for around an hour, they'll lose less battery with deep idle than without.
You won't actually save battery if your phone is actually idle with deep idle enabled.
It's not some kind of magical function that makes your phone use less battery doing tasks with the screen on, deep idle disables certain components of the phone while executing tasks with the screen off, instead of having it "at full speed" as if the screen was on.
Now I understood. Thank you very much.

No problem. I think Deep Idle is probably the mod by Ezekeel surrounded by the most misconceptions.
Most new users want it absolutely but don't seem to know why.
On His Glados kernel I noticed that Android OS was using 20%-21% of the battery and on the stock kernel 30%-31%.
Android System was using around 14% and on the stock around 19%.
Ok, have you decided to give the Glados 2.2 another go? I believe I have finally tweaked it so that it is stable for me.
Before I was getting restarts within 30 seconds of the screen turning off. I have cornered this (on my phone at least) to a problem with NSTools auto-setting the lower frequency to 100mhz. Changing it back to 200mhz and I have yet to see the system restart itself. Im not overclocked, because I dont see the point as everything is fairly snappy with this new kernel. I dont really play games on it so Im not fussed.
I did used NSTools and the frequency was set to 200mhz and I had system restarting on screen off. Using stock ICS with Glados 2.2
Also I had green annoying flickr on locking and unlocking the screen.
I fully charged the phone to 100% and turned it on at 7:45 then I went back to sleep. I woke up at 10 to see the phone at 95%! Now, I'm currently using the Anker battery & I'm running on ARHD 3.6.13 with faux123 v0.2.8 kernel. The brightness is at its lowest & auto-sync is off. What should I do?
I recommend using Battery monitor widget Pro to see how much mA is phone using during sleep and when screen's on. Then install Better Battery Stats ( http://forum.xda-developers.com/showthread.php?t=1179809 ) and figure out, what is eating your energy
also, try undervolting

What's undervolting?
Undervolt makes your cpu use less energy. for undervolting try using system tuner pro or faux clock (here's link for faux's RootzWiki: http://rootzwiki.com/topic/4550-app09-beta-snapdragon-dual-core-oc-control/ ) But be aware that not every CPU handles heavy undervolting well. Do nandroid backup, then Start with -25mV.

Try changing cpu governor to intellidemand (faux's kernel default) and min speed for cpu to 192. It may slightly improve battery life.

Hi,
When I was on 3.6.x,it was suggested that I try a Bricked kernel,which you can find HERE
I am not sure which one,but they tended to be more battery friendly than faux.
Read the thread.
You might get some valuable information.
Hi all,
I have been using the ONDEMAND CPU governor for quite a while on my SGS4G running CM9 (Team Acid's version, the final herring one), and I have just gotten used to the 12-14 hour battery life that I have had ever since I switched from GB back in August 2012. However, most of the frequent users here recommend the SMARTASSV2 governor, so I tried to use that yesterday to see if battery life was enhanced.
If anything it seems that my battery life got worse (see attached picture). I am a moderate phone user in general; I use my phone for texting mostly, and sometimes I'll look something up on the Internet, but no music, WiFi and GPS are always turned off, no overclocking/undervolting. I recently purchased a new battery as my old one died about two months ago.
I was wondering, is there any governor for the CM9 ROM that is particularly good with battery but doesn't completely drain performance?
(Also, I tried to use the LZ kernel before, but it seemed to cause many more problems than it fixed.)
You've got some pretty bad wakelocks going on there. See how your phone is awake even though your screen is off? That is an issue. Also how much screen on time did you have on that run? Get Better Battery Stats(free on XDA) then fully charge and look at what wakelocks are occurring. You might also want to consider UVing if you want better battery life.
Also, if you're a fan of ondemand, I highly suggest moving to ondemandX, which actually does deep sleep when the phone is off.
But that will only help if you fix the wakelocks first. So follow hechoen's advice and your phone should be way more awesome.
Downloaded BBS today, we'll see how it goes.

Running the latest version of GimmeABreak, stock kernel. Using it as just a home use wifi phone, so mobile data is turned off. However for some reason cell standby is using a large portion of my battery.
Is there anything I can do to get about better life out of my inspire? I ran through both the battery saving threads in the guides sticky but it doesn't seem to be a rogue app causing the drain.

*Edit - To clarify (as I wrote this post late and under the influence of several Tylenol pm) I really just want to know if there is a way to disable cell standby as I don't need a cell signal for a wifi only phone. Thanks in advance for any help anyone can provide
