I'm looking for a rom with best battery life for QHD+ and 90 Hz. already tried OOS 11 but found it a bit lackluster, are there any better alternatives? thanks in advance

They all act differently with different usage and different kernels installed. The only real way is to try them yourself, besides that's half the fun.

I just upgraded to Android 11 and the battery life is definitely worse than Android 11 with OOS nd stock kernel. Like @hammered58 said, you'll get the difference by using a different kernel.

Other apps like UniversalGMSDoze (Magisk) or Greenify are not updated for Android 11 yet as far as I know. Android 11 seems to have changed a lot in the battery department.
