In the iPhone (in this case 15, with iOS 17), when I go to **Mobile service > Mobile data options > Voice & Data** and 5G is enabled (**On** or **Auto**) the following message is displayed:
> 5G may impact battery life and reliability of some voice calls and data.
It’s understandable that 5G impacts battery life. But I could not find any documentation that implied that the reliability of voice calls or cellular data could potentially have a negative impact, due to 5G.
Why is this disclaimer relevant? Where can we find more info about this?
