They are broadly the same. It’s a bit more dynamic now rather than on/off but still throttling based on battery health. They are probably monitoring the rails and clocking down directly on a feedback loop which is the way to do it if you want to eke out all the performance you can. 11 and above: > While performance impacts are reduced as much as possible, battery ageing might still eventually lead to noticeable, possibly temporary, effects. Depending on the battery state, level of charge and the tasks that your iPhone is handling, examples might include longer app launch times, lower frame rates, increased processing times, reduced wireless-data throughput, backlight dimming or lower speaker volume. During the most extreme cases, the camera flash or other camera features might be temporarily disabled. https://support.apple.com/en-gb/106348 https://support.apple.com/en-gb/106348 Below 11: > Additionally, you can see if the performance-management feature, which dynamically manages maximum performance to prevent unexpected shutdowns, is on, and you can choose to turn it off. This feature is enabled only after an unexpected shutdown first occurs on a device with a battery that has diminished ability to deliver maximum instantaneous power. This feature applies to iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE (1st generation), iPhone 7 and iPhone 7 Plus. Starting with iOS 12.1, iPhone 8, iPhone 8 Plus and iPhone X include this feature; iPhone XS, iPhone XS Max and iPhone XR include this feature starting with iOS 13.1. https://support.apple.com/en-gb/101575 https://support.apple.com/en-gb/101575
