Although it is still more than half a year before Apple officially announces iOS 16 at the annual WWDC event, recently, the iPhonesoft page has said that the new iOS 16 version will no longer support updates on devices. running Apple A9 chip, including iPhone 6s, 6s Plus as well as iPhone SE.
With iPad, the following devices will not support the iPadOS 16 update: iPad mini 4, iPad Air 2, iPad Gen 5, and iPad Pro 2015.
If this information is true, the iPhone 6s and iPhone 6s Plus duo has officially been killed after 7 years of launch with 6 iOS updates (launched with iOS 9 and updated to iOS 15). This is a relatively long period of time and hardly any product line on the market has such a long update period.
Of course, the above information is still just a rumor and has not been confirmed by Apple. Anyway, we still need to wait until the WWDC 2022 event held in June next year to get official information, where Apple introduces iOS 16 beta to developers. However, before that, iPhonesoft also made accurate predictions about devices that support updating to iOS 13 and iOS 14, so it is likely that the iPhone 6s and 6s Plus may be officially discontinued next year. because this duo has outdated hardware.
Thus, to be supported updating to the latest iOS 16, iPhone and iPad devices with Apple A10 chip or higher are eligible for the update, that is, from iPhone 7 or later.
