With yourself and a coincidental comment making such reasonable corrections I investigated further. Posted below for posterity, not necessarily you. The reddit post: https://www.reddit.com/r/iphone/comments/7inu45/psa_iphone_slow_try_replacing_your_battery/ https://www.reddit.com/r/iphone/comments/7inu45/psa_iphone_s... Finally, from the horses mouth:https://support.apple.com/en-us/HT208387 https://support.apple.com/en-us/HT208387 "iOS 11.3 and later improve this performance management feature" and "iPhone 8 and later use a more advanced hardware and software ..[snip].. As a result, the impacts of performance management may be less noticeable on iPhone 8 and later." My conclusion: It is true that Apple was only targeting phones with dodgy(to a degree of approximation) batteries. OTOH, Apple does a better job now. Both in execution and communication. Whether Apple would have reached this achievement without batterygate is unknowable. My apologies for spreading misinformation, thank you for your patience. Edit:snipped some bits for conciseness.
