iOS 12.1 Brings Apple’s Controversial Performance Throttling Feature to iPhone X and iPhone 8

iPhone X Lock screen No Notifications Locked

Apple is bringing its “performance management feature” to last year’s iPhone X and iPhone 8 series with its iOS 12.1 update. For the unknown, this ‘feature’ will throttle the devices as their battery performance degrades over time.

The same feature was responsible for slowing down older iPhones over time as their battery capacity degraded over time. When Apple confirmed last year that it was intentionally slowing down older iPhones, it noted that the iPhone X and iPhone 8 series were exempt from it due to hardware updates.

However, with the iOS 12.1 update, Apple is bringing the same performance management feature to the iPhone X and iPhone 8. The company has silently updated its support page to reflect the change as well.

Below is what the support page originally mentioned:

iPhone 8 and later use a more advanced hardware and software design that provides a more accurate estimation of both power needs and the battery’s power capability to maximize overall system performance. This allows a different performance management system that more precisely allows iOS to anticipate and avoid an unexpected shutdown. As a result, the impacts of performance management may be less noticeable on iPhone 8 and later. Over time, the rechargeable batteries in all iPhone models will diminish in their capacity and peak performance and will eventually need to be replaced.

And below is what the updated support page says:

Additionally, users can see if the performance management feature that dynamically manages maximum performance to prevent unexpected shutdowns is on and can choose to turn it off … This feature applies to iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, and iPhone 7 Plus. 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.

Thankfully, thanks to all the hue and cry that was raised last year after Apple confirmed it was intentionally slowing down older iPhones, there’s an option to turn off this “performance management feature.” This might lead your iPhone to reboot when under heavy load but it will at least ensure the performance of the device is not being throttled.

Given that the iPhone 8 and iPhone X are just over a year old, it is unlikely that their battery performance has degraded a lot. Over the next couple of years though, the batteries inside these devices will degrade noticeably which is when this ‘performance management feature’ will start rearing its ugly head.
