After a few days of using I can tell it's not a good ROM after MIUI13.
The battery life much worse with stock kernel, when I install aRise X2 kernel the idle consumption got better, but not always. (AoD and notification screen waking are off.)
Charging speed is only fast not super fast like in MIUI and the phone got warm like super fast charge. Same warm longer time is not so good for the battery.
Animations are lagging, this is the most annoying thing. (Poco F1 PE has the same, so it's a PE bug, in CrDroid and Lineage no lagg).
Uploading doesn't work when the screen locks.(onedrive, gdrive).
Fingerprint scanner is slower.
Automatic brightness is a crap.
I feel the screen darker in daylight (I don't know which kernel supports the high brightness mode and DC dimming, because it's offline in the settings).
Poco F1 12L version have more Live Display settings than Poco F2 12L PE, it's opposite in MIUI...
