Apple supports phones longer than any other manufacturer with immediate updates that don’t leave you waiting for months wondering when your specific phone will get it.

In addition, the oldest phone currently supported by iOS 16 is the iPhone 7, released in 2016. However, most apps (for example YouTube) only require around iOS 14 to work. And the oldest phone that can run those is the iPhone 6s from 2015.

So unless you’re the type to keep the same device for 8 years, you will never need to buy a new iPhone to use apps.
