The problem is not new features, but bloat. Look at stack traces on recent versions of iOS, or at the view hierarchy, or at the method table of NSObject. Apple is rushing out junk software by adding another fat layer of duct tape every year.
iOS 11 is just as terrible on the 5s as iOS 9 was on the iPhone 4s. Within two years, the OS has caught up with a 4.5x increase in CPU performance! I'm not talking about 3D games, just unlocking the phone, taking pictures, launching apps, chatting on iMessage/WhatsApp. And iOS 11 should actually be more lightweight since it has dropped support for 32-bit apps.
