The primary go-to settings of 5G on iPhone are overall battery life and data sets usage, depending on your data plan. After looking at the data usage based on your plan, you can always choose how your phone uses 5G data. It can have an effect on the battery life in the following ways: Here are some of the specifics about 5G possibilities:
1. 5G Auto: In this, you can enable smart data mode. When the 5G does not provide good speeds, your phone goes to LTE mode to preserve battery life. That Is because when you go for faster speeds, it takes a toll on your battery.
2. 5G On: When you go for this, you always use a 5G network. This scenario consumes more data and affects battery life. One upside is that you will have good internet connectivity.
3. LTE: You can use this low data mode and save the data. This scenario will affect the upload speeds but saves battery.
