Root Best ROM for battery life?

Whats a kernel and how do I get it to work?


A kernel is the piece of software that goes between the rom and your physical phone. It is flashed thru cwm(recovery) and depending on which one you choose to use there may be no setup required to tweaking undervolts(not recommended for beginners). Sometimes, take the acs frozen rom for example, comes with the twilight kernel. Well you may like the rom itself but you are having some issues. It is sometimes suggested to try another kernel like the genocide kernel. All of our phones, even though they are the same, react differently. Some people can run anything and overclock(oc) and undervolt(uv) with no issues while others cant tolerate certain roms let alone any kind of oc or uv. Hope i am making sense for ya! ;-) if not let me know.

In case you weren't aware, most of the ROM's have kernels where you can tweak the settings using Voltage Control and/or SetCPU. You can play around with the settings to get the best balance between performance and battery life...

Voltage Control has the advantage of being able to change the voltage setting (undervolt) and overclock, while SetCPU only let's you set the processor speed.

Which ROM has voltage control?

Voltage Control is just the app that controls it. I believe the ability to do undervolting is kernel specific, not based on ROM. Though some ROMs include kernels which have UV'ing capabilities, so that would make people think it's based on ROM, which isn't really true.

Personally, I've had the best experience with Genocide kernel with the SRF 1.2 ROM. The default kernel with SRF is usually Twilight Zone, which is also good, I just personally have beter experience with Genocide.
