Invalid POCO F3 switch off by itself

[Shijokin]

Hello,
I just got a new POCO F3 from Spain. Anroid 11, Miui 12.0.2
This morning I woke up but the phone was off!
I switched It on and the battery indicated the same percentage as when I fell asleep, 38%.
This is the first time something like this has happened to me.
Any help?
Thank you

Our only Stable ROM for Redmi K40/POCO F3 is V12.0.7.0, which means you're using an official Global ROM, so seek help from Xiaomi directly.
