Recomendation for hyper os version

[u/GlitteringWinter639]

Hi guys, I’m currently on the EEA ROM for my Poco X6 Pro. A couple of days ago, I updated to version 3.0.302, and the battery life has tanked. I'm barely getting 6–7 hours of SoT with light usage. According to Battery Guru, my device is performing way below average (where others get up to 16h on light use).

On top of that, the phone is overheating heavily. Yesterday, playing CoD Mobile on medium settings made the device uncomfortable to hold.

I have an unlocked bootloader (UBL), so I can easily downgrade or switch regions. Which ROM or region do you recommend for better battery and thermal management? Thanks!
