[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Moe_KH:
I can help you with this, I have been collecting bloatware package names from across a vast variety of custom roms, as well as MIUI stock roms.

But remember, if you're on Android 11, don't uninstall Cell Broadcast Reciever, Android ONS, Cacert App, Ims Service, otherwise you'll get stuck in a bootloop

I have removed the packages that might result in a bootloop for you, so you're good to go, debloat whatever you want, and you can ask me about any package name that you're not familiar with.

Note: to add the list below, in Xiaomi ADB Fastboot Tools, click app manager then add apps and paste the package names you wanna uninstall/disable then hit ok. After doing so, the list of the apps/services will appear then you can choose what to disable/uninstall.

Note: if you want more ram and better performance with functionality, uninstall Gapps, excluding G-play services & play store if you use them, like those of the google safety hub app, device personlization services, google carrier services, and last but not least (disable) Android notification ranker service.

If you want more battery, uninstall Qualcomm Useshimservice com.qualcomm.useShimservice listed below.

Good Luck.
