It seems that fast draining battery is such a ‘phenomenon’ with which we all have to live forever. It doesn’t matter even with the latest and improved Android version 7.0 Nougat there is a battery drain issue. Even with most equipped smartphones like Google Pixel/Pixel XL too suffer from fast battery drain problem. But there is a good solution for it, and that is to toggle data off when using WiFi on Android automatically.
What normally happens is that if you are making phone calls and receiving text messages along with your good WiFi connection is going on, there is no need to have data running.

Well, there is an app called RadioControl which will come to our rescue.
