I had my phone replaced today as it was super slow on Wifi and the cellular data is pretty useless. The WiFi speeds are not comparable to my iPhone 8...which is better. They were averaging 1/4 the speed of my 8. I can’t say that the reception is better....but at least something is better. My max has a terrible time getting reception back once it loses reception. It has to be restarted or data cycled on and off for it to start working again. Here’s to hoping Apple fixes this mess!
