14 DAY TRIAL // In the iOS 12.1 release notes, Apple mentions that last year's iPhone 8, iPhone 8 Plus, and iPhone X will also feature the highly controversial processor throttling feature.
Moreover, according to Apple, iOS 12.1 "adds a performance management feature to prevent the device from unexpectedly shutting down, including the option to disable this feature if an unexpected shutdown occurs, for iPhone X, iPhone 8 and iPhone 8 Plus."
However, Apple says that given the "more advanced hardware and software design" in last year's iPhone models the throttling of the performance designed to lower performance peaks to stop the device from unexpectedly shutting down will be a lot less noticeable.
"This performance management works by looking at a combination of the device temperature, battery state of charge, and battery impedance," according to Apple.
"Only if these variables require it, iOS will dynamically manage the maximum performance of some system components, such as the CPU and GPU, in order to prevent unexpected shutdowns."
iPhone 8 and iPhone X running iOS 12.1 will have their performance throttled to prevent accidental shutdowns
Furthermore, the iPhone 8 and iPhone X use a more accurate performance management method because of their more powerful hardware, allowing iOS to anticipate and steer clear of sudden shutdown events a lot more precisely,
As Apple says on their "iPhone Battery and Performance" support page, "over time, the rechargeable batteries in all iPhone models will diminish in their capacity and peak performance and will eventually need to be replaced."
The performance management feature will be enabled automatically once the iPhone starts encountering issues after the maximum battery capacity goes below 80%.
Although there is no way to enable it for iPhones that have batteries working at peak performance, users can choose to toggle it on or off once it is automatically enabled on their devices.
This feature, also described by many as "planned obsolescence," was behind the Apple's €5 million ($5.7 million) fine received from Italy's Autorità Garante della Concorrenza e del Mercato (AGCM ) for failing to inform iPhone 6/6Plus and 6s/6sPlus owners that the iPhone 7-optimized iOS 10 would also come with higher energy demands that could lead to unexpected shutdowns.
