OK, so I see some people having issues woththis rom, but for me mi 10 is working very very cool (~literary, check the pics below). Also, thanks
@geoorg, deleting the data of the gallery app probably fixed my battery drain.
@WinterWarrior67, if I remember well you too had issues with gallery app.
What I did was to boot into twrp, delete the data of the app (cuz settings ~don't have an option too), deleted package cache and cache+dalvik (after and before ~each step) and before rebooting, I flashed the same rom too.
To see what to delete go here:
(Btw, ~no need to delete: "Internal storage/android/data/gallery_disk_cache", it's ~already inside the rest of the folders that you'll delete.)
If you want, use a root explorerto create a zip backup of the data, I did that too, but didn't use it.
Finally, the gallery after rebooting showed extreme usage, probably due to 2 reasons:
1)After deleting its data, it ~had to scan the whole storage (lagged so much I had to reboot). You should probably initiate the process by opening the gallery app.
2)The battery stats ~weren't reset, so it was probably counting the battery usage before deleting the data.
