Copy my settings , they seem to work fantastic for battery life. 18-22hrs uptime and 4-6hrs awake

some have seen around 30hrs on the stock battery

thanks for the reply chitown i just followed the instruction that guy has given. now my question is do i need any other program like kernel also to be running and does the SETCPU always running and saving my battery as recommended by you on ur guide? one more thing how did you get ur battery icon to show the percantages like what app?


thank you once again

yeah install either a hydra undervolted kernal or the new kings kernal . Do a search on the site you should be able to find it.

You should still see battery improvments with the stock kernal but with a good undervolted kernal you will see much more. This thread was with Hydra Undervolted Overclocked kernal

So, you are running an undervolted kernel?

If I do a nandroid, will the kernel be backed up?

I'd like to try the kernel and, if all goes well and I notice an improvement in battery life, I'd like to do a nandroid backup.

By the way, with SetCPU, I noticed that if I set the max clock speed to ~850 MHz on the main screen, the current clockspeed will still spike to 998 (or whatever the max is), and that's with Perfclock Disabled.

Any ideas what's going on? Is that how it's supposed to work?

Do I need to use the Perflock Disabler often, or just when I start the application?

 

[ChiTownJim]

I honestly don't know how SetCPU works on the stock kernal never used it with the stock kernal I've never noticed the CPU going higher then what I have it set to in SetCPU . With any aftermarket Kernals you don't need to disable perflock but I do believe you need to with the stock kernal or else everytime you shut down you basically disable SetCPU

 

[dscribe]

On stock kernel you have to disable perflock and there are fewer governor options available from the kernel to show up in setcpu.
