Yes that has become pretty well known and puts people off buying 2nd hand, in reality it shouldn’t put anyone off as it’s not hard to keep one going for 5+ years.

“Lifecycle” is not an apple specific thing. Literally everything has a lifecycle that makes the device obsolete/unsupported before it’s useful age is up.

Technology in phones (primarily SoCs, batteries, and displays) moves faster then other categories, leading to the one year generations, but again, that’s something every brand does. It’s insane to suggest that companies continue to maintain old platforms that are in comparatively few pockets against discovered security vulnerabilities or leveraging new features beyond the capabilities of their hardware.

iPhone 8 is now nearly six years old and supports IOS16, with rumors that it may support 17. I’d be surprised if it does, but that’s still a very impressive lifespan for a mobile phone.

I understand apple hate but this is really one place where it’s undeserved.
