How should I disable wave animation I have seen in my device running Lollipop that, when charges get below 15% the device get into Battery Saver mode, in which all the animation of the Android get disabled (like, Wave animation).
So, I just wanted to disable that animation manually, how can I do that, anyone know please share it.

Note:  I have rooted phone
You could try  setting the animation scale to 0% (in developer options)

If it is not enabled already, go to Settings > About phone and then tap Build number seven times. 

After that Settings > Developer options will be available.

In the developer mode and set animation scale to .0% (or off)
