is a 6s model obsolete soon?

A phone isn't really obsolete until it no longer functions. Such as older phones that only supported 3G networks become instant relics when all carriers shut that service down.

A 6s is somewhat old and will never get another major iOS release. It's stuck on iOS 15.x now and can't be upgraded to iOS 16. How long Apple will provide security updates for it is another question.

But regardless, you can still use your phone, so I personally wouldn't call it obsolete.

Hello Oldguychizmay9,

This is a great question. Luckily Apple has some great documentation regarding this. Take a look at this site. Obtaining service for your Apple product after an expired warranty - Apple Support

There is a chart for iPhones that lists the 6s as vintage but not obsolete. I hope this helps.

Thank you
