For all of you that have gained root access, I will show you how to dramatically increase your battery life

Step 1: Download SetCPU from the market or get its via XDA-Dev

Step 2: Install it and allow SuperUser.apk to gain access

Step 3: Leave the settings alone on the main tab. Should be at the top of the max bar and the bottom of the min bar with ondemand selected in the scaling.

Step 4: Check "Set on Boot" on the main tab

Step 5: On the Profile tab, check "Enable" and "Notifications"

Step 6: Click "Add Profile" and add the following profiles

Quote:

Condition : Charging USB/Full
Max: High as the bar will go
Min: Low as the bar will go
Governor: ondemand
Priority: 50

Quote:

Condition : Charging AC/Full
Max: High as the bar will go
Min: Low as the bar will go
Governor: ondemand
Priority: 50

Quote:

Condition : Screen Off
Max: 384000
Min: Low as the bar will go
Governor: ondemand
Priority: 50

Quote:

Condition : Battery <
Battery<: 30%
Max: 38400
Min: Low as the bar will go
Governor: ondemand
Priority: 50

What this will do is change your CPU usage depending on the state of your phone.

The phone will be allowed to run on full power when on charge if needed.
When the screen is turned off the CPU will run between 245 and 384mhz
When the battery is below 30% the CPU will run between 245 and 384mhz

You should find this will save a ton of battery. I have had ebuddy running in the background for almost 5 hours with 3G connectivity and my battery is at 72%

You can get more juice from your battery is you use JuiceDefender.
Also, remember to add SetCPU in your task manager ignore list!
