Well, sure what you say is true, and it’s part of how some Android manufacturers (along with service providers who also play a role) integrate planned obsolescence to try and make their smartphones disposable. It is also true that Apple products hold their resale value longer, so a 2nd-hand iPhone is more likely to get back into someone’s hands and be used. Still, my Galaxy S7 has had a security update in the past 2 months, and it has had two OS upgrades from Android 6 to 7, and now to 8.0 Oreo.

Apple support for 5-year old phones… but not 6-year old ones I think. The current version of iOS 12 is not supported on the iPhone 5, released 6 years ago. And that 5-year number is less impressive when you think that the iPhone 5S (the oldest currently supported phone) was sold new in stores for 2-and-a-half years. It’s also much less impressive when you think that the iPhone 5C, released at the same time as the 5S, is no longer supported.

So Apple actually doesn’t support its phones for 5 years, not the budget versions. I wonder if the Xr will be supported for less time than the Xs.
