Hi there Smartphone users,

We all know Xiaomi/Redmi/Mi phones are BEST equipped with more hardware and more software (features).

Often users complain about heating issues and fast battery draining issues.

Those who are complaining about these issues need to set up phone properly.

The below setup procedure is applicable to most Xiaomi Redmi Mi phones however it perfectly fits and applied on my secondary device Redmi 4x running Android 7 with Miui 11 while 95% of these settings are applied on my primary device that is Redmi Note 9 Pro Max running Android 11 with Miui 12.5.5 (I'm 4 crappy updates behind for GOOD :)

Note: Where ever I use the word ‘CHECK’ in below procedure, it means Turn on, Select etc.

Where ever I use the word ‘UNCHECK’ in below procedure, it means Turn off, Unselect etc.

So let's begin:...

1. Factory reset the phone.

Choose language

Choose Your Region

Choose Keyboard

Privacy Policy (Check and agree)

Insert Sim Card (Skip this)

Connect to network (Skip)

Google Services (Uncheck 'Send Usage and diagnostic data)

Set password (Skip)

Additional settings (UNCHECK THE FOLLOWING OPTIONS)

-Location

-Send usage and diagnostic data

-Automatic system updates

-Personalised ads

Select default launcher

2. Go to Settings / About Phone / System update / THREE DOT MENU / Update settings /

a. Download automatically [UNCHECK]

b. Download using Mobile data [UNCHECK]

3 Go to Settings / System apps updater / THREE DOT MENU / Settings / Auto updates / Don't update.

4. Settings / Wallpaper / SCROLL DOWN / Find more / Profile Icon in bottom right corner / Settings / Recommendations [UNCHECK]

5. Settings / Lock screen & password / Advanced settings / Pocket Mode [CHECK]

6. Settings / Notifications & Status bar / Show connection speed [CHECK]

7. Settings / Google / Ads / Opt out of Ads personalization [CHECK]

8. Settings / System app settings / System app updater / Auto updates / Don’t update [SELECT]

9. Settings / Quick apps / Performance optimization /

a. Preload pages [CHECK]

b. Auto Updates [ UNCHECK]

10. Settings / System app settings / Security / Cleaner/

a. Update automatically [UNCHECK]

b. Receive recommendations [UNCHECK]

11. Settings / System app settings / Security / Security Scan / Auto Updates : Avast [UNCHECK]

12. Settings / System app settings / Security / Receive recommendations [UNCHECK]

13.. Settings / System app settings / Music / Receive recommendations [UNCHECK]

14. Settings / Manage apps / THREE DOT MENU ICON / Settings / Recommendations [UNCHECK]

15. Settings / Manage apps / Uninstall [UNINSTALL THE APPS WHICH YOU THINK YOU DO NOT NEED]. In my case the apps I uninstalled were Mi Store, News, Newsdog, Mi Credit etc.

16. Settings / Manage apps / Find apps / Me (Profile icon) / Gear Icon (Settings) / Delete Package [UNCHECK]

17. Now let’s tweak important system apps:

a. File manager / THREE LINE MENU ICON / About / Recommendation [UNCHECK]

b. ShareMe / THREE LINE MENU ICON / About / Auto Updates / Don’t update [CHECK]

c. MiVideo / THREE LINE MENU ICON / About / Auto updates / Don’t update [CHECK]

d. Phone / THREE LINE MENU ICON / Identify phone numbers / Caller ID / [CHECK]

Tip: NEVER USE TRUECALLER instead use this Caller ID feature which is in most Mi/Redmi/Xiaomi phones and is safe.

18. Now connect to Wifi and quickly open PlayStore / THREE DOT MENU ICON / Settings / Network Preferences / Auto-update apps / Don’t auto-update apps.

Tip: NEVER UPDATE THE APPS unless they are not working because all updates are not good and many app updates are made to work with newer phones so when you update, it could not work properly on YOUR phone.

19. Settings / Manage apps / THREE DOT MENU ICON / Show all apps / UNINSTALL OR DISABLE THE FOLLOWING APPS

a. Duo

b. Facebook App Installer (You can install proper Facebook from PlayStore later)

c. Facebook App Manager

d. Facebook Services

e. Google Play Music

f. Google Play Movies & TV

g. Mi Pay

20. Settings / Permissions / Autostart [UNCHECK ALL THE ITEMS WHICH ARE NOT REQUIRED TO RUN AT PHONE START UP]

All the above settings you'll find in all the Xiaomi / Redmi / Mi phones however they could be jumbled here and there depending on the Android and Miui versions and you can figure it out easily.

21. Cultivate good charging habit. Never drain battery to 0% and never charge it to full 100%. Maintain 20%-90% charge always.

You are all set. Now let me know if the heating issue exists or battery is draining fast.
