4. Greenify app (full version i.e. donation package)

5. Swift Installer

Note - Please reboot after each magisk module is installed. If rebooting after multiple module installed at once phone may stuck on bootloop.

Steps -

Kernel Adiutor

1. Install FKM (Franko kernel manager) - go to the app ->

click on CPU tab ->

For 'Big Cores' set maximum frequency to 2169 Mhz ->

later set CPU governor to 'powersave' only for 'Big Cores -> toggle the option to 'on'.

Thats it, leave the 'little cores' as it is. -> REBOOT

2. Ater the FKM settings has been applied, install the 'Kernel Adiutor' app ->

click the 3 lines options from the top left screen ->

Click on 'CPU' tab -> For 'Big Cores' set maximum frequency to 2169 Mhz ->

set CPU governor to 'powersave' only for 'Big Cores ->

set CPU governor to 'schedutil' for 'little Cores'. turn on 'Apply on boot' option.

3. Now go to the 'GPU' tab from 3 lines menu -> set CPU governor to msm-adreno-tz' ->turn on 'Apply on boot' option.

4. Now go to the 'Low memory killer' tab from 3 lines menu -> click once on 'very light' -> turn on 'Apply on boot' option.

5. Uninstall the FKM app. REBOOT.

Debloat

Warning : For this please keep ready the LGUP tool and proper .kdz file for your device [i repeat do not ignore this]

Here are some of the apps that i debloted using 'debloat' magisk module->

1. Photos

2. Lens

3. Google Play Music

4. Calender (dont debloat if you want to sync it)

5. Chrome

6. Docs

7. Google text-to-speech engine

8. Gmail

9. Duo

10. Slides

11. Sheets

12. Gboard (Google keyboard)

13. Google Play movies

14. Google Maps

15. Google News

16. Facebook App Manager

17. Facebook App Installer

18. Youtube (If you debloat it, it wont run, it needs system access. Since i used Youtube Vanced i dont care)

Until this after rebooting all worked well.

But After debloating '19. Google' and rebooting my phone, it bootlooped. Thus, I have to LGUP and select the 'upgrade' option and flash the stock again and it worked fine and i successfully debloated the 'Google' app too. This is the main battery culprit. Or you you can just disable it. see if it works for you or not.

Note :- Debloat doesn't mean uninstalling, it means converting system apps to normal apps just opposite what the 'Sytemizer' magisk module does.

Greenify

1. install the greenify app (full version needed) -> then go to the Edxposed Manager -> click on 3 line menu -> click on module -> turn on 'greenify' -> REBOOT.

2. Open Greenify app -> Give it all the permissions needed -> now to go the setting from the 3 dots menu -> It should be showing working mode 'Root + Boost (Xposed)'.

3. Smart Hibernation = Enabled; Aggressive Doze = Enabled; Wake-up tracking and cut-off = Enabled; Automatic Hibernation = select it; Always ignore backgrounf free = select it.

4. Now click on Xposed-based features -> select each and every options.

5. Reboot the greenify app.

6. Now on the main screen of greenify, click on the 'zzz' icon and select the apps it recommends and most of the apps u dont care much about and click them for sleep just once and never again.

Swift Installer -

1. If you are using substratum please STOP. It drains a hell lot of battery.

2. Use swift installer instead for theming various apps you like.

3. And for system theming any good theme from PlayStore could work.

Major Note :- This isn-t the fool proof method of increasing battery life out of nowhere without losing some performance.

Sure it will, but you will even not notice it and will easily get you through it. Atleast it happens well with me :cool:

For Gamers : Just take away the root access from the Kernel Aduitor from Magisk Manager and reboot when you want to play system heavy games.

For All : if you notice any lag which annoys you, please start tweaking the 'Greenify' first rather than going directly after 'Kernel Aduitor'.

Please provide the precious feedback and other tweaks and tricks here to further improve the Battery and Performance of our beloved Phone LGv40.

I will be posting battery backup, SOT proofs stay tuned.
