acdha addressed the feature issue very well I think, it's not just about one or two features and when Apple does execute a feature they often do it better. ProMotion actually saves battery overall by often clocking the display down fo static images. Qualcomm's engineering team is just fine, the problem in their economics don't work for making truly high end chips. It's the most expensive engineering they do, but only a tiny fraction of the Android handsets sold carry flagship chips. Meanwhile all iPhones are effectively flagship devices.
A lot (but not all for sure) of the A-series chip performance advantage comes from a massive on-die cache for example. That's not fancy engineering, just brute force transistor count. Qualcomm engineers could absolutely do that, but Android handset economics won't support it.
