Most Stable and Battery Friendly ROM for SM-G900F?

[LawUysal]

I will start to use a new S5 but I want to have a long battery duration. Now I'm on Havoc OS (Android 10) with Intelli kernel (Conservative Governor). But it seems like it has very limited battery saving features. I'm wanting most stable and least Battery drainer one. Can any one help?

Hi, Android 11 is awesome with battery usage and Dark mode.
