It wasn’t that long ago when Apple promised that the iPhone 8 and iPhone X will not be throttled. In the end, however, the two phones end up being victims of what Apple calls “performance management feature.”
The company has previously told US Senator John Thune that the iPhone 8, 8 Plus and X will not be affected by the throttling as they had new enough hardware to manage performance, so that the issue with battery degradation will not affect these devices too badly. The statement that proves otherwise can be found in the support page, which has been stealthily amended.
As spotted by The Verge, a sentence was added to Apple’s support page, under the Battery Health category:
Starting with iOS 12.1, iPhone 8, iPhone 8 Plus, and iPhone X include this feature, but performance management may be less noticeable due to their more advanced hardware and software design.
Fortunately, it will still be possible to turn the feature off. This will allow your iPhones to run at full performance, but it may speed up battery degradation and other associated strains on the phones.
It’s still odd for Apple to promise not to throttle its previous generation phones, only to make a U-turn immediately after releasing iOS 12.1. Throttling iPhones in general has already gotten Apple in legal trouble.
