When will the iPhone 6s Plus no longer update
I read on a website that in 2024 the apple iPhone 6s Plus will no longer get updated software how true is that?
iPhone 6s Plus, iOS 15
See this Apple product list:--> Obtaining service for your Apple product after an expired warranty
iPhone 6s or 6sPlus models were firstly released on September 25, 2015. They support iOS 15.8 version and, even if they are going to become obsolete in 2024 or 2025, that doesn't mean that you can't use them, being aware of their limits.
