[Redmi Note 2 Android Development] jajk:
[MENTION=7180732]spoof123[/MENTION] I assume you are on 80xx in which case use the 6915 v5 image. Link in O.P points to all available versions;)

Now for a bit on disabling services... Read carefully because I will laugh when you stuff it up because you are out of your depth or cannot comprehend what you are doing (You are a NOOB but can't accept it)

First stage: (recommended for beginners)

[B]Disabling Autostarts using SD Maid:[/B]

[B]Autostart must be left enabled:[/B]
Android System
Clock
Device Provisioner
Media Storage
Messenger (or whatever your chosen messaging app is)
MTK Thermal Manager
Permission Manager
Security
Settings
SuperSU
System UI

[B]Can be or should be disabled:[/B]
Atci_service
Contacts Storage
Download Manager
*Kernel Adiutor
MIUI SDK
MTK NLP Service
Omacp
One Time Init
Phone (com.android.phone)
*SD Maid
SIM Toolkit
Themes
Updater
*VLC
Xiaomi service framework *(should also be frozen)

Second Stage: Using MyAndroidTools to disable services and broadcast receivers: (For the more experienced)

Notes:

Do a MyAndroidTools Backup before you start and re-save it as a reference should you need to backtrack on what you have done. The app doesn't have a method of returning to stock settings.

Some items will be already disabled by SD Maid (or similar app) and by the corresponding app itself. Do not re-enable something that was already marked as disabled.

Assumes you are NOT using any Xiaomi services and all non-essential Xiaomi apps are removed.

No Gapps related components shown - highly recommended not to mess with any Gapps settings - you will always loose the battle.

Don't play with Activity or Content Provider settings - you will break things for no gain.
