Hey!
Any idea where I can see how long my phone has been running or when the last time it was fully charged? Battery usage stats only show the last 24 hours.
Mi 9 SE, MIUI 12 20.5.21
You could try SHRP.

Format data in TWRP and confirm with YES. Don't wipe, just format data. Boot into Fastboot. Copy rom to internal storage or use USB OTG. Then install rom. Helped me, no guarantee.
