[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Danny94:
General informations​

I have returned to miui xiaomi.eu 10.3.17 10.3.16 PIE (care your sensors break from downgrading) as i get really good results for battery and performance. I propably will stay on this rom until i get a new device, because of that i wasted a lot of hours to debloat my device as good as possible and i want to share my results with you (im not a pro so take all with a grain of salt).

Remember this debloat list is highly customized at my own usage, some services could stop working for you and you could end up in bootloop when you have logged into mi account and remove related services for example. I advice a fresh install and dont open/ log in into a single app/service. You should check each row by yourself if you want to remove that app or not, i have added to almost each row a description (from own research and other research lists now only from universal debloater)

EDIT 02.02.2022: unluckily i just came now across with this insane universal debloater , here you can find all descriptions and by far better and more accurate than mines.

I am not responsible you breaking your phone with this list, all the modifications are done by you.

How to install my list:​

Root via magisk is required. For debloating i have used the magisk module "Debloater - Debloat Systemlessly" and you need a root file explorer.

Copy with the root file explorer one of the files to /data/adb and rename it to "deblaot-backup.txt", than install the module. After reboot all apps from the list should be removed (but i have not tested it like that by myself)

To remove your own apps or reinstall some of the removed apps you can simply install a terminal like termux and follow the instructions on the link above.

In Short:

su
deblaot

and choose your option from delete app or delete priv-app or reinstall app.

You stuck in bootloop:​

Go to your recovery and simply delete the module at /data/adb/modules/terminal_debloater. All apps will return.

Safe debloat list:​

I have noticed that debloating some apps/services can cause more battery drain, even some spyware crap (check old thread edits at the bottom), because routines start looping infinity to restart the debloated service. So i started from 0 again and this time i add only stuff which shouldnt affect battery negativly. To make this happen i need to test all changes for a longer time period so the list will grow with time slowly starting from 05.02.2022.

03.03.2022 New list on xiaomi.eu miui 10.3.16, unluckily i dont have time to copy all the descriptions and make the still running services list (but its quite similar). This time i have debloated almost everything stock related and i havent noticed any drawback as my sot is 10h+ and idle 0% and i couldnt found any annoying errors in the background, so eveything might be ok. [you need to replace contacts, gallery, keyboard (playstore), sms, telefon app...before debloating i am using the "simple" ones from f-droid]

There are still a few ones which i like to debloat like:

com.miui.guardprovider (antivirus scam) [probably break app install]

com.miui.catcherpatch (no clue)

com.android.wallpaperbackup

org.simalliance.openmobileapi.service

com.xiaomi.tproxy

com.miui.vpnsdkmanager

com.android.providers.userdictionary

com.android.emergency

com.miui.dmregservice

com.miui.extraphoto

com.miui.audioeffect

...

but im at the moment very happy with the result so i dont try further. You can also try to freeze them with greenify or superfreezz if you are using one of them anyway to limit your user apps like me.
