Below are the few steps you need to do to improve your phone's battery life.

NOTE: Your phone must be rooted for this to work.

Step 1
Download MTK6577 CPU Governor from XDA. (Awesome app)
Here is the link:

Step 2
Next install it and open the app.

I haven't noticed any bugs. Everything works perfectly fine. If you experience any difficulties then please comment below and tell me your problem. :)

** UPDATE**
After flashing this rom, the phone heats up a lot and also the battery backup isn't that good. This is because the kernel governor set by xolo is hybrid. This for some reason conflicts with this rom and hence it heats the phone up. To fix that just follow the simple steps in this post:

The problem will be solved. I'm still using this rom. There are absolutely no bugs and it's pure android. No modifications and you can install the google apps you require. :)
