Apple iPhone X, iPhone 8, 8 Plus get controversial throttling feature with iOS 12.1 update

Apple iOS 12.1 has created throttling issues on the iPhone X, iPhone 8 Plus and iPhone 8. The phenomenon leads to a drop in battery performance, that prevents the phone from shutdowns.

Apple’s recent software upgrade iOS 12.1 will bring the controversial processor performance management feature to the iPhone X, iPhone 8 and iPhone 8 Plus. This particular ‘performance management’ had caused a lot of controversy for Apple when it was discovered in December last year.

Apple had then issued a detailed apology and denied that it had tried to slow down older devices. The support page for the iPhone battery and performance now mentions the feature for iPhone 8, iPhone X and iPhone 8 Plus with iOS 12.1 update.

“This performance management feature is specific to iPhone and does not apply to any other Apple products. 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,” reads the support page.

With Apple will start introducing peak performance management in these devices, it could impact the overall speed of the device. However, Apple is insisting the impact will be less on the phones due to better hardware and software.

The latest throttling feature was reported after some Reddit users upgraded their iPhone 8 series device/iPhone X to the new iOS. Within the update, Apple listed a new performance management feature under the ‘Other improvements and Fixes’ sub-head of the iOS 12.1 update description.

The company has said in the past that the feature has been introduced for these iPhones, to ensure that the device will not experience unexpected shutdowns, which could happen due to issues with battery, which can crop up over time. Lithium-ion batteries deteriorate over time, which can cause some performance issue.

Apple also states that users can choose to turn off the feature, though users were unable to spot the same in the iPhone 8 series or iPhone X.

The support page explains, “This performance management works by looking at a combination of the device temperature, battery state of charge, and battery impedance. 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.”

The throttling issue was also addressed by US Senator John Thune, who sent a letter to the Cupertino-based company, asking them to detail the nature of its software upgrades for iPhone X/iPhone 8 Plus/iPhone 8. In response, Apple mentioned that the hardware on these phones will be compatible with software updates related to performance optimisation, from which ‘iOS would anticipate and prevent accidental shutdowns’.

Similar issues had appeared last year that involved phones from the iPhone 7/iPhone 7 Plus and below. In response to the growing demand for a fix, Apple did offer battery replacement for the iPhones, which would eliminate the throttling issue, it claimed.

Recently, the iPhone maker had also been charged with a $5.7 million fine by Italy’s anti-trust agency for deliberately slowing down devices.
