iOS 15: These devices are believed to be supported
The next WWDC will take place in around six months, where we will see iOS 15, among other things. Rumor has it that two iPhones are no longer receiving the update.
iOS 15 should be compatible with all iPhones that came on the market from September 2016. In addition, the seventh generation iPod touch should also be supported. So the iPhone 7 and 7 Plus will probably still get the latest version of iOS. Accordingly, it is time for users of an iPhone 6S, 6S Plus and SE (first generation) to get a new smartphone - these devices are probably no longer supported.
The latter was to be expected anyway, as Apple usually provides the iPhones with updates for five years. With their release in September 2015 and March, this year was the last year in which the three models received an update. The source does not reveal what it looks like with the iPads and iPadOS.
