I run ubuntu 2404 on my 2017 thinkpad fine, although I have replaced the battery (and about to again), upgraded the ram etc, not expecting to replace it for some more years yet.

My iphone 12 mini is from 2020 and is fine, so 5 years. Next ios release still supports 2019 iphone 11s, dropping the 2018 era, so apple seems to give 7 years for a phone, which doesn't seem terrible for closed source software.
