Elruki cpu profiles:

extreme battery saving : max speed when screen is off is 480 , max speed when screen is on is 600

battery saving : max speed whe screen is off is 480; max speed when screen is on is 800 (simulated by governor)

normal : not capped. slighty more battery friendly than stock settings.

All of the above use ondemand governor.

performance: not capped, always use max speed , performance governor

Viper4android.

I Included some IRS samples and profiles, profiles where modified to my earphones, you may want to modify them, You can check originals in ViPER4android original thread, I modified values in ViPER4androidFx Dynamic system-> listening device and dynamic bass. also look for the thread for extra profiles and IRS samples in original thread.

Viper4android is heavy on cpu resources if you use IRS samples , use normal profile in elruki cpu profiles so you don't get sound glitches when screen is off and on, and to not slow wake speed.
