[Galaxy S I9000 General] TheBlackWolf:
Disclaimer; This does not damage your phone at all or fry/mess your cpu.

This method is used to lower CPU stress and increase Battery life:D

This method works for all rooted phones.

IMPORTANT: The newer versions of SetCPU might prevent your phone from entering deep sleep. Download version 2.24 from the following link which is the one with no problems and completely works 100%.

LINK

Deep Sleep breaks when charger is plugged in, you can see this by CPU SPY application available on playstore

Stop Downloading Battery Saving Applications, they do nothing and uses RAM.:silly:

Also Turn BLN off when you are sleeping.(It also Consumes battery and sometimes prevent deep sleep of CPU)

Set your Brightness to minimum and disable auto brightness.

LINK to Display Brightness

Instead use lite app called - Display Brightness from play store.

Turn off wifi and mobile data when not in use.

Use toggle for auto rotation, and keep off when not needed.

For more battery Saving, disable all animations and set screen timeout to 1min.

The S plus sucks in battery life. We all know that.But here's a fix, Try Under clocking instead of Over clocking.

When screen is on:

MAX 1.4Ghz(Why to OC??, if your phone runs smoothly on 1.4Ghz)

MIN 192Mhz

Ondemand governor (This governor jumps up to max when needed but spends most time on the min freq. Best battery saver.)

;)

When screen is off:

MAX 365 Mhz

MIN 192 MHz

(This prevents lagging when playing music and other activities when screen off)

This way, you have a beast quick phone when you're using it, and the best battery saver when you're not!

NOTE: Turn off Autosync from the settings. It's only used to sync your gmail and contacts and such. You can manually sync when you add a new contact and since I don't use gmail, I refresh manually whenever I do.

SetCPU:LINK

Specific instructions for those that can't get it to work!:

On SetCPU:

Click Add profile

Where it says Profile, select it and tap "Screen Off"

Set the frequencies you want in use while screen is off (If you want just one frecuency, put both sliders on the same number)

Set priority (in case you have other profiles, otherwise don't bother)

Select governor (Won't really matter since cpu is gonna be running at 1 frecuency)

Tap save

Go back to Profiles tab at the top, then tap Enable at the top left to make the profiles work.

For a list of most governors and I/O schedulers detailed;

To check if its all working, install CPU spy from the playstore: LINK

For Playing GAMES(HD)/HEAVY GAMES, Plug your Charger in and play if possible.:good:

Most Important thing is to calibrate battery,

Calibration of battery is needed when you change your ROM.

This process wipes batterystats.

Battery Calibration

1. Charge 100%(NON STOP)

2. Download any battery Calibration tool from play store; (Link to App)

3. Open that app, click battery calibrate

6. Unplug your charger

7. Discharge your phone down to 0% during the day

8. Charge back up to 100% (NON STOP)

This is to make sure you're using your battery at 100%. Only do this after you flash a new rom.

The worst battery killer is 3G. No matter how much you try to optimize battery by tweaking and underclock, if you have 3G on, you're gonna have a bad battery drain.

Make sure that Autosync is disabled.;)

Done A small test usage 14 mins:p , you can see in attachment your CPU should look like this.
