Sounds temptingJust installed latest PixelOS. coming from latest MIUI13. A while ago I already was on PixelOS but changed back due to some issues.
Battery life is great. Maybe its just me, but this what I did: Was on MIUI13 and still had OrangeFoxRecovery installed. I just downloaded latest PixelOS, put it on my SDCard. Reboot to recovery and erased Data, Dalvic Cache...everything including Cache.
Skipped the part "Download the latest MIUI 13 firmware for your region"
I dunno if this made the difference, but i thought: Im already on latest MIUI13, so why do this step?
Just installed PixelOS, wiped data and rebooted. Installed at least 30 Apps, launcher and a few other things. Was on 73% before sleep. Left everything on: Bluetooth, Wlan, Mobile connection, GPS, NFC. Woke up 5 hours later, still on 72%.
