My iphone 15 pro max has a bad 5g connection. Compared to my iphone 13 its nearly half the speed in the 5g network. Both up- and downstream. And compared to a samsung its the same? Anyone who knows why the the signal detection is so bad in the ”premium iphone”? Changed sim card, restarted and cant find any settings thats wrong (but i must or the phone is bad).
