We know more and more about the upcoming 13-series of iPhones day by day. The new series of flagships from Apple will bring users some new features. Almost certainly the 13 Pro and 13 Pro Max phones will receive an LTPO screen with a dynamic image refresh rate. In addition, the latest information indicates that users will receive the long-awaited always-on display function in new phones.

It is worth mentioning that the always-on display function has been a standard in Android phones for some time, but it will be the first time such an add-on will appear in smartphones manufactured by Apple. The function is to work in a similar way to the always-on display in Apple Watch watches. That's why we can expect that iPhones, after turning on this function, will display basic information such as the current time, date and notifications when the screen is turned off.
