For Advanced users

​

Q1) Battery is draining fast?

A) After flashing the kernel please calibrate your battery or else let 3-4 full battery cycles pass.

Q2) Which profiles should i use?

A) Lets take example that you are using Ultimate kernel. Keep the governor ondemand (Like every good boyfriend fulfills all demands of his girlfriend ondemand governor does the same for your CPU :D).

Make profiles:-

1) Time Profile - 12 am to 6.00 am Freq 100 Mhz to 400 Mhz Priority 100

2) Screen Off - Freq 100 Mhz to 600 Mhz Priority 95

Q3) What are advanced settings in the SetCPU mean?

A) Sampling rate is rate at which the frequency of your CPU changes. Up Threshold is limit at which CPU will change freq on load (Scales Up). Down Threshold (conservative only) is limit at which CPU will change freq on load (Scales Down). Powersave bias is used for saving the power of CPU, it will slow down the CPU and affect the performance also 200 in powersave bias mean 20%...250 means 25% and so on.

Q4) I want performance and also good battery what profiles should be i use?

A) Refer to Q2 for Profiles Set up and now go in Advanced tab and Keep Sampling Rate 10000 or 15000. Upper Threshold to 90 and Powersave bias to 200 (20%). Since we are using powersave bias, this will affect the performance as it slows down the CPU so to increase the performance we are lowering the Sampling rate thus we get perfect balance of Performance and good battery backup.

NOTE: ABOVE SETTINGS ARE JUST EXAMPLE..PLEASE PLAY AROUND AND CHOOSE SETTINGS WHICH SUITS YOU THE BEST
