[Q] stock kernel and battery life

Hello, I'm about to jump from 4.3 stock I9300, to OmniROM for first time.
I will flash omni-4.4.4-20141113-i9300-NIGHTLY and wanted to ask is the stock kernel good for battery life and is ArchiKernel_V1.5.4-AOSP better?

[Q] Best ROM for i9500 with no bugs and best battery life

Hi my friend has been complaining about her battery life and she's on stock kitkat i9500.
So I would like to change her rom, can anyone suggest me any stock lollipop rom that has the best battery life,no bugs and has still has all the features from the stock s4 (dual window, etc)?
And is it preferable to flash the Lightweight lollipop kernel?
p/s: I have little experience dealing with samsung, which is why I'm going to learn thoroughly after knowing which rom to flash. If anyone can help me out from the bottom (pm maybe) I would really appreciate that too :good:

Help selecting a kernel

Hi, I have a galaxy S5 g900V that has a stock Marshmallow ROM for T-Mobile that I de-bloated using an extreme debloater script. It works great but my battery life is less than desirable. I tried the Imperius Curse and it had great performance and battery but I could not get ADB and a few other things to go so I flashed the Phoenix kernel to fix those issues and it is very stable, reliable.
I am looking for a performance kernel that will have good battery life and be stable. I really like KTOONZ kernel on my galaxy S3 - amazing - but he says his kernel only works for g900f. Has anyone tried it on other S5 variants?
Can anyone recommend a kernel? This phone is my daily driver so "trying" kernels that have not been proven on g900v sounds too risky.
thanks!

Resurrection Remix OS Battery Drain on Exynos

Hey guys, yesterday I installed RR (latest version) on my s7 edge Exynos G935F and I am suffering from a really bad battery drain and a really slow charging.
-I did a clean flash
-Before this rom I had another Touchwiz rom that was really stable and had a great battery life (just for information)
What should I do?
Thanks a lot in advance
