Hyper battery drain...

Hello world! I'll go straight to the subject:

Just updated my Mi 11 to HyperOS 1.0.8 and it's disastrous firmware. Can't use my phone ! I tried resetting (twice). Any ideas/fix ?

5G off, 120Hz and WQHD, some things off like location and NFC. Also tried with FHD resolution and still nothing.

It is very frustratin.
