Fortunately, Apple has given you control over your phone’s 5G connection. With just a few taps, you can turn off the new feature or adjust how and when it is used to download updates, for example.
To be clear, Apple has built a new Smart Data feature into the iPhone 12’s software that only uses a 5G connection if you are doing something that requires it, such as streaming a video or playing a game over a cell link. The purpose of switching between an LTE and 5G connection in the background is to extend the battery life of the iPhone 12. The shortening of the battery life can therefore be negligible. I personally haven’t been able to test the difference as I don’t have 5G coverage.
That said, if you don’t want or need your phone to connect to a 5G network, you can turn off 5G with just a few taps on your iPhone’s screen.
Disabling 5G on iPhone 12
Open the Settings app then go to Mobile > Mobile data options > Speech and data and tap LTE. Your phone will then turn off the 5G connection and revert to (sometimes) slower LTE connection. You can always turn 5G back on whenever you want, or whenever the service improves in your area by repeating and selecting the steps above 5G Auto. Or if you prefer your iPhone 12 not to use Apple’s Smart Data mode, you can force it to always use a 5G connection, if available by selecting 5G on.
One more thing …
If you decide you want to leave your iPhone 12’s 5G connection on 5G Auto, it is a good idea to double-check this setting.
Go to Settings > Mobile > Mobile data options > Data mode on your iPhone. There you will find three different options for how aggressive your iPhone will be with how apps and services can use your 5G connection.
For example with Allow more data on 5G selected, your FaceTime and streaming video will come through in “high quality,” and you can even download future iOS updates over a 5G connection.
Read the descriptions for each data mode and select the one that works best for you – and remember, even if, chances are there is some kind of limit after which your internet speeds will slow down.
