And it’s not the first time it happens, and it’s very visible. Every time we upgraded (even iOS 7 and 9, macOS, ...), everything went slower. Transparency, 3D, probably reduced swap space or cache sizes calculated for models with more RAM, etc. Given upgrades are mandatory (user is spammed until he upgrades), given those features are planned without a flag to turn it off for older phones/iPads, and given it’s the only way to receive maintenance for the phone (i.e. security updates), it’s planned obsolescence. Think every time you brought your car to a repairshop they would load it with unused equipment designed for bigger models, both clogging your trunk and making your car so heavy it loses 80% of its speed. Wow, didn’t think the comparison would be so accurate.
