New iOS 15 and its news

NIQ ??Which iPhone will be compatible with iOS 15? iOS 14 started with the iPhone 6s, the iPhone SE (1st generation) and the iPod touch (7th generation) as older devices that were still compatible with it and the natural thing is that this list is cut in the next one. Sometimes the “limiting reactant” is the processor, and according to MacWorld the Apple A9 will be left out of the list, and therefore also some of those devices. This would be the list of devices compatible with iOS 15??.
