Even with the fastest processors, incredible displays and unbelievable features on our Android smartphones, we are still enslaved to the wall socket. While battery performance has increased over the past few years, you still need tricks to conserve the juice, such as the ability to automatically toggle data off when using Wi-Fi.

Since you can make phone calls, send and receive text messages and still enjoy high-speed Wi-Fi at the same time, having the mobile data on is a waste of battery. With the help of an innovative app created by developer Nikhil Paranjape, you can automatically toggle data off when using Wi-Fi.

DID YOU KNOW: Updato offers seamless and guaranteed phone unlocking for any device, carrier and region! It's quick and easy - try it now.

Step 1: Download RadioControl App

While the RadioControl app that helps you automate mobile data is free to download, it does require root access. If you are aware of the risks and still want to continue, do check out our Android rooting guide to know more.

Step 2: Grant the App Root Access
