Device sales have been stagnant since 2015, both for Apple and for the smartphone market as a whole. It isn't surprising that Apple has peaked, it had to happen at some point. Devices are lasting longer so active devices can climb for a while even after sales level off.
The next few years will be interesting. Hardware revenue is going to fluctuate in a narrow range unless Apple does something stupid to drive users away. Future growth is very limited even with China and India being underrepresented. Services are key and Apple is investing heavily into that market. We'll just have to wait a couple more years to be able to see if that works out and can drive revenue and profit growth at a rate that supports the company's market value.
