I see no reason to upgrade my 15pm for at least 3 more years. Prices keep going up with nothing new introduced.
Prices keep going up? 16 Pro and Pro Max prices are the same as last year.
In fact, the starting price of an iPhone 11 Pro (64GB) was $999 which was the same starting price as an iPhone 12 Pro which was the same starting price as an iPhone 13 Pro which was the same starting price as an iPhone 14 Pro which was the same starting price as an iPhone 15 Pro which is the same starting price as the just announced iPhone 16 Pro and each (12 to 16) have twice the storage (128GB) as the 11.
