In 2017, Apple was embroiled in an iPhone slowdown saga, wherein the company admitted to slowing down old iPhone models to prevent unexpected shutdowns. The feature was meant to keep the smartphones running longer, and Apple’s failure in bringing more clarity to the matter led it to initiate a battery replacement program throughout 2018, apart from rolling out battery health information and performance throttling options in iOS. Now, Apple has released a new support document that claims that the new iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max phones include a dynamic power management system that uses hardware and software to reduce performance impacts as their batteries chemically age. The company also has confirmed that the iPhone XS, iPhone XS Max, and iPhone XR will get a performance management feature with iOS 13.1 update next week, but did not clarify if it would be identical to the one seen on the iPhone 11 series.
Apple says that the new built-in performance management software and hardware system integrated in the new iPhone 11 series is automatic, always-on, and works to provide the best possible performance as battery ageing occurs over time. It also says that it is more advanced than the previous battery and power management methods, but battery ageing will over the course of time lead to longer app launch times, lower frame rates, reduced wireless-data throughput, backlight dimming, or lower speaker volume.
