Lately I've tried to use underclock and undervolt to improve the bad battery life of the Mi4c. I tried different values on the XOSP 7.1 (https://forum.xda-developers.com/mi-4c/development/unofficial-xosp-7-1-libra-aqua-t3551296) in the past days, and I discovered a combination of clock of the cpu and governor that seems to work quite nicely.
REQUIREMENTS:
Rooted phone
Kernel that provides the possibility to change this values
Busybox and Kernel Adiutor or analogue app
Recommended the use of XOSP 7.1 Rom (Not necessary)
Greenify
STEPS:
After having enabled the root access to busybox and Kernel Adiutor(the apps will ask you this to you when you first open them, just check "enable"), enter in Kernel Adiutor in the CPU section and dial in the following values.
BIG CORES: Max Frequency = 864 Mhz / Min = 302 Mhz
SMALL CORES: Max Frequency = 672 Mhz / Min = 302 Mhz
For both cores use "smartmax" Governor (this setting is right below the Frequency dials).
GPU: Max Frequency = 450 Mhz / Min = 180 Mhz.
Governor: simple_ondemand.
As last step, go in development settings and watch for active apps that you don't need and with Greenify disable them. This should help the battery even more. Remember to freeze only apps that don't send notification, otherwise you will not receive them until you open the apps.
REVIEW:
Yesterday I had a pretty heavy day, I used the phone quite a lot both with Wi-Fi and 3G and I ended up with 4:30 h Screen On Time and I even had 20% left. I really hope that this may help some of you because I know how stressful this is and I decided to share my experience with you.
