Using 4G internet connection

When you switch on your smartphone’s data connection, battery consumption goes up significantly. The battery will drain even faster if you are using a 4G connection.

It takes a lot of power from your battery to keep your phone connected to the 4G network. At the same time, if you are browsing the internet or chatting, the app is also using up your battery.

In the end, the battery may last half of the time it would if you were not using it heavily. Most modern smartphones regulate internet connection and you will often get a notification that your internet connection is using up too much power.
