How to Save Battery Life by Turning Off 5G on iPhone

Connecting to lightning fast 5G networks, requires a sacrifice: battery life. But Apple baked a Smart Data Mode setting into new iPhones to give you more control over using 5G.

Connecting to lightning fast 5G networks, requires a sacrifice: battery life. But Apple baked a Smart Data Mode setting into new iPhones to give you more control over using 5G.

Apple gives you three options: You can keep 5G on all the time, switch over to LTE and never use 5G, or allow your iPhone to make that decision for you with an auto mode. There is no reason to upgrade to an iPhone 12 just for the 5G feature because the network carriers are behind the iPhone hardware. 6G is already in the works and Apple is planning on using it in its iPhone 13 lineup.

But, if you have an iPhone 12, here is how to easily turn off 5G to save your battery life.

This is for iPhone 12 lineup
