so out of all kernels you would recommend dk 2.4.3. for best battery life... have you compared your findings with void. echo and siyah? siyah was good for battery life before matched with wajkiui but then after updated to latest kernel my battery is dying... void.echo is worse... pls help.. battery life is my biggest problem! will your settings differ for different batteries i currently have a 2000amh.. and switch between the original when one dies... at this rate il need a third battery =_=

As i mentioned in first post miui+siyah dont gave me good battery. About void.echo i faced os drain bug. So for me dk and xcell was best....

First go for dk 2.4.3 and follow all the steps.

Thanks for this gh.rohit

Might want to in OP that turning of push feature and using k-9 or manual sync saves a lot of Battery. Not everyone needs instant notification of a mail etc.

thanks Guys

dk 2.4.3 kernel does not support clock by clock voltage? or is it the voltage control that is the issue? ( Hope not since I really like it. Thanks for posting it old SetCPU user..)
