Battery drain and Heat issues

[Black Heaven]

I have the last stock rom 12.0.15 and I don't know why but even with the big battery, i feel a drastic battery drain, at 60hz or 120hz( it's the same) it feels really warm even with the transparente case

This problem is so big that my 2 years old mi 8 Lite with miui 11 retains a lot more battery...more than 50% at the end of the day

So is it me or this phone it's really bad optimized? how well optimized is the xiaomi.eu 12.0.12? Do i have a faulty unit?

No problems with 12.0.13.0. May be a faulty unit or bad rom. But I do not have update to 12.0.15.0.

I'm just waiting for the 7 days to try the most recent stable ROM f Om here Buy How do i know what's causing the overheating and battery drain?. I attached an imagen of the stock ROM that i have.

Edit: in another thread some users report a normal temperature of 37°c (that my RN10PRO has) but in the mi 8 Lite it shows 32°c. How can it be that an LCD screen and with snapdragon 660 generates 5°c less of difference against a 732G and Amoled screen. For me it seems that Even with the good Specs of this phone, they went chip with the componentes. I don't know.
