Tips & Tricks: 

1. For those who have Wifi issue, can try out this code in build.prop to see whether it makes any differences:
a) Change:
wifi.supplicant_scan_interval=150
b) Add below this code:
net.tcp.buffersize.wifi=4096,87380,256960,4096,163 84,256960

2-a. To reduce CPU speed in order to save the battery: 
1. Install Setcpu in Google Play
2. Set Cpu to on demand instead of performance.
3. Save and monitor the battery life again.

2-b. A few profiles in setcpu to help manage the power ( Thanks to lansi23 )
There are 4 speeds for the phone:
