[Xiaomi Mi CC9 / Mi 9 Lite Guides, News, & Discussi] banes768:
My device is the Mi 9 Lite, purchased from eBay Germany and I have Global Miui 11.

Going to make this a list of packages which can be removed and/or what they do as much as I can.

If you try any of this keep in mind this is a WIP and I say be cautios. The worst that can happen upon removing EVERY single mi-related package is,

your phone hangs up, you have to boot into recovery and factory reset. Meaning you should back up your data beforehand but that's literally all.

I did that several times in a row but I was able to narrow down apps you don't particularly need unless you use them.

You have to connect via adb shell and I'm not going into that because there is plenty of guides out there.

There was an incredibly useful article on Fossbytes, just look it up.

These packages that can be removed safely, the phone will boot just fine and I notice not a single issue.

Keep in mind that if there's apps that you use you obviously don't wanna mess with those:

The following packages should not be removed or at least they broke something:

pm uninstall -k --user 0 com.android.providers.calendar # not safe to remove, messes up the clock and can't use either calendar nor download from playstore anymore

pm uninstall -k --user 0 com.xiaomi.finddevice #issue: pop-up bubble "FindDevice has been destroyed" According to Google breaks boot and have to factory reset

pm uninstall -k --user 0 com.miui.notification #warning: this will break notification settings and make them inaccessible

pm uninstall -k --user 0 com.miui.miwallpaper # Mi Wallpapers. Update: Not neccessarily broken but it removes the default app for Wallpaper selection and makes setting a new wallpaper obnoxiously complicated. First you have to use a different app like Google but then it's not guaranteed that you can change your lock screen wall.

Upon removing one of the following packages my phone stopped booting and I had to factory reset:

pm uninstall -k --user 0 com.miui.securityadd # Security Center

pm uninstall -k --user 0 com.miui.securitycenter # Security Center

pm uninstall -k --user 0 com.miui.securitycore # Security Center

And here's the packages which are still open for experimentation, the list is very small now and if somebody wants to give it a spin I would very much appreciate it:
