[LeEco Le Pro3 ROMs, Kernels, Recoveries, & Other D] SUMMERBREEZE:
These are my settings but i m not %100 sure it will work same on others. But lets at least TRY :)

Do number 1 to 3 from TWRP

1) Flash the rom

2) Flash gapps

3) Flash magisk for root access

and boot :)

**************************

4) Install Kernel Auditor

5) Install Greenify

And now, lets tweak Kernel Auditor, AICP rom system settings and AICP extras and then Greenify.

**************************

Kernel Auditor:

CPU - Change big cluster to 1900 mhz, Small cluster to 1593 mhz and change cpu governors to alucard for both big and little cpu.

GPU - change gpu max frequency to 510 mhz and gpu governor to simple_ondemand

I/O Scheduler - change scheduler to noop, read-ahead to 128KB

Low memory killer - change it to aggressive

Misc - change vibration strength to %10, disable Fsync

Remember to enable ''apply on boot'' option for each sectors.

**************************

Lets do some system tweaks.

Settings/developer options - logger buffer sizes to OFF (enable this back if you later want to provide logcat)

Disable all animations

**************************

Settings/Go to navigation and enable navigation bar instead back-lit hardware keys. This will save a big juice from the battery, you will get used to it very soon.

Settings/Display/Adaptive brightess - ON (this might be laggy but saves juice from battery)

I also keep SYNC off in Accounts/Google. It helps for battery, if you need it, of course it is up to you.

Settings/Location - Keep it off unless you need it.

Settings/Battery/3dots/Check if there are any apss out of from battery optimization. If there is/are, then put it/them under optimization back.

**************************

Now lets go to AICP extras

Go to Various ****, enable sensor block per-package, go to suspend actions and enable it and under mobile networks enable ''switch to 2G '' option when the screen is off and the phone is in idle for overnight etc.

Turn off the ota checker from AICP extras/about/update center/3 lines 1 on the other/settings

**************************

The last thing is to use greenify. From settings , enable aggressive doze and doze on the go. And then make your own way to disable background apps. Remember, dont hibernate such apps whatsapp, messenger, gmail if you need notifications..

Thats it, of course i might have forgetten something still to add, but more or less these are my settings. I will add if i remember something more :)

Also try to keep the screen brightness as low as possible, dont use gps./cellular network and wifi when you dont need. You can also figure out yourself which apps/services are draining battery in usage/idle, for this you can use wakelock dedector from google play for it and share it here and ask what to do with them, we will find a way to solve it.

Hope this tutorial helps! :good:
