Basically I'm trying to lengthen battery life by keeping the cpu in a weak state while the screen is off.
But it almost feels like since I installed SetCPU by battery life decreased?
The only profile I have active is for the cpu to slow down to 500 when screen is off. But Stweaks came with my rom I have installed.
What shall I do?

Is it possible set CPU can make my battery life worse? im not overclocking it, or underclocking, pluse my phones a little laggy
Anythings possible, I know setCPU didn't play nice with my Samsung, but I dont have any issues with the EVO. The only setting I use is to underclock waaaaay down when the screen is off.
You need to list what settings you are using

My questions is why do we need to use setcpu when we can use built in cpu tuner on CM7, profiles?? Last time I check whenever your not using your phone ei. screen off or left it by the table your cpu will automatically tune it to the lowest right??
EDIT: maybe we need profiles for battery percentage

wondering the same thing
I have always been a user of SetCPU and profiles, but two days ago I finally decided to give to built-in CPU tuner on CM7 a try, and it seems a little better on battery life and I do not notice any diffrence in the performance. I think I will stick to using the built in CPU tuner for now and see how it goes.
I've been using the built in cpu on CM7 for 2hours it drained me 19% of the battery light usage but I'm gonna try until it drains to 0%, my battery normally last for 13-16 hours on setcpu 248-1017 profile and I'm using the same on built it.

actually, where is the option for the built in CPU Tuner, is there even one? or does it run automatically?

thanks for the fast replies, am gonna flash it right now
I was wondering what everyone uses or their min/max speeds? Ive been using the mild overclock settings with the 245/1024 setting currently, but will increasing it to say 1200mhz really hurt my battery life a lot? Will the 1200mhz speed only kick in when theres a game or something else resource intensive?
depends on your settings, try using an app like set cpu or anything that allows you to use profiles, this way you can help control battery life while still overclocking how youd like. well somewhat better control

The battery life is also rely on what governor that control the cpu.

No matter which ROM i choose wether its 2.3 based or 4.0 based, Calks or Phantom. Even CM9, Team Dirt. I always get crap battery life. ANDROID OS and ANDROID SYSTEM hog the battery!!! Why is this. The only thing that has not changed will i have been flashing all these roms is the Modem. I am currrently running FF18 Modem. Could this be the culprit? Please help guys!
The android os usage in ICS is normal. What do you consider bad battery life?
So many things affect battery life. Low signal will wipe out a battery in no time, synching multiple accounts (email, facebook is notoriously bad...) and software you may have installed. How is the battery drain when the phone is sleeping? Since there really isn't much we can do about battery while you're actually using the phone, the next step is to improve on sleep efficiency and this will help the battery life overall.
Try installing BetterBatteryStats. There is a thread here on XDA you can search for and download and install this app. The best way to use it is to let the phone sleep on battery without using it for a minimum of 2-3 hours, overnight is best. Then view the kernel and partial wakelocks to see if something isn't allowing the phone to sleep properly.
battery battery life?
Couldn't you also use multiple profiles in an OC app to undervolt and underclock the phone when it sleeps? (screen off profile set to 800MHz and screen on 1200MHz) Just a suggestion, hope this helps.
I have to charge my phone twice a day because I am on it all the time. My ave battery life 11hr 47min. Running Badass Battery Monitor.
Turn off auto sync for your Google account on your phone and manually sync it from time to time. Before I did this android was at the top of the list in the battery. Now screen time dominates everything else in usage.

Yes I did this too, it helps a lot
Yes, synching too often is a killer.
Don't forget about the phone radio too: wifi/bluetooth/gps/data/4G all can have a negative impact if left running.
Someone recently posted that at his workplace, he had zero signal and he could barely make it through the day. He discovered turning data off entirely in that scenario saved battery in a huge way.

Bad battery to me is loosing 60% over night. That's running CM9, android is and system were the dominant battery hogs when that happened. Please help. I've downloaded betterbatterystats.apk but I don't know how to use it. Please help.

I guess you should try downloading any battery calibration app from the market and also try battery control.... I hope it would help you..... Or the usual juice defender :thumbup:

I recommend underclock your cpu to 1 ghz
I've been under clocked @ 1.0

I am running stock ICS, with the cpu sleeper app running and my "awake" time is crazy high. I use to have awesome battery life pre ICS, oh and I forgot to mention that I have the nexus extended battery what is running and how can I kill it....I use to get around 19 to 25+ hours before zero now I don't. I have tried to celebrate the battery by letting it run to zero, wiping battery stats and having it charge up to 100% powered off and it still suck. What am I doing wrong? Also I enclosed a pic of my current battery stats for all to see

I suggest getting GSam battery monitor and seeing what is killing your battery. If you really want improvement root that bad boy and gets your self a custom ROM!
Here is my battery life, typical day. AOKP 7/15 with latest CPU sleeper.

Have you looked through the battery stats list of what been running to try and track it down that way? I've also hers people say if your using google voice and restored it from a backup that it will cause wake lock. Uninstall and reinstall from the market if that's the case.

Also try out CPU Sleeper: http://forum.xda-developers.com/showthread.php?t=1745516
This is also hosted in google play.
Description of the badass governor:
Badass removes all of this "fast peaking" to the max frequency. On a typical system the cpu won't go above 918Mhz and therefore stay cool and will use less power. To trigger a frequency increase, the system must run a bit @ 918Mhz with high load, then the frequency is bumped to 1188Mhz. If that is still not enough the governor gives you full throttle. (this transition should not take longer than 2-5 seconds, depending on the load your system is experiencing)
Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1188Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.
