I can’t speak for anyone but myself but, my iPhone 11 hadn’t slowed down in any way. The battery was down to 82% Maximum Capacity, so I was wondering whether to simply get a new battery or to upgrade. In February I upgraded to a 15 Pro Max. I was ready for a newer model (with a bigger screen) and for some better camera features. I’m quite happy with it. A friend is equally happy with my iPhone 11 (with a new third-party battery I got fitted).Didn't include "because we will slow your old one down" huh?
I’ve never had any issues with my iPhones (since 2008) or iPads (since 2010) suffering from slowdowns.
