Invalid Poco F2 Pro battery drain

[Tha_Chii]

Hey, Ive got a new Poco F2 and after setting it up, the battery life is horrible! Its draining 10% while using only whatsapp. The settings and apps are the same like the old phone, and there was not such a horrible drain :-(! You can see, that the apps are not using that much battery life?!.

Rom: Miui 12.1, 20.9.3 Beta

Is this a bug caused by this rom? Should I go stable or wait for the new weekly? Thank you!

Hi! Same phone, same weekly, but different results. I have a good battery life. Did you clean cache/dalvik?

I did a data wipe, than I was in the Bootloop.. after installing the ROM I startet it. Thats it. Now I did a Cache clean, but I guess thats to late?

How is the best way to install it clean?

Thats not normal I guess. @ 8am Ive got 80%, @ 18o clock Ive got 20%. It was tha whole day in my backpack, as you can see (time in use "Ruhezustand" vs. active)
