Huawei wont get far in western markets when theyre equipment is being banned by the Five Eyes countries and theyre advising against using their devices.
Asia, middle east, africa, latin america theyll do great.
Apples problem tbh is phones are as good as they can get, camera from 2015/6 still good, screens from then still good, still powerful enough for apps etc, the only thing that would be fucked is the battery, and you can get that replaced cheaper than a new iphone so why bother? best they can do is use updates to slow the phone down.
the battery replacements are affecting them
