I wouldn’t expect a downgrade. So far the SE has always been at least as good as the same-form factor regular iPhone it copied. The first SE was a 5S with 6S internals, and was released only 6 month after the 6S.The upside could be that this 6.1” SE will have great battery life because the display will probably be less bright and lower pixel density than iPhones 13, 14 and 15.
