The iPhone 11 series has a new hardware and software management system to reduce performance impacts as the battery ages: Apple

In 2017, Apple was embroiled in an iPhone slowdown saga, in which the company admitted to slowing down older iPhone models to avoid unexpected shutdowns. The feature was intended to extend the operation of smartphones, and Apple’s failure to provide further clarity on the matter led it to launch a battery replacement program throughout 2018, in addition to rolling out new ones. Battery health information and performance limiting options in iOS. Now Apple has released a new support document that claims 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 impacts on performance as their batteries chemically age. The company also confirmed that the iPhone XS, iPhone XS Max, and iPhone XR will get a performance management feature with the iOS 13.1 update next week, but did not say whether it will be. same as that of the iPhone 11 series.

Apple says the new performance management software and hardware system built into the new iPhone 11 series are automatic, always on, and work to deliver the best possible performance as the battery ages over time. It also states that it is more advanced than previous methods of battery and power management, but the aging of the battery will over time lead to longer app launch times, higher frame rates. lower, reduced wireless data rate, dimmed backlight, or lower speaker volume.

The company advises in its supporting document that users regularly check their battery status by visiting Settings> Battery> Battery status, and get a replacement if health gets really bad.

In a separate supporting document, Apple confirms that the iPhone XS, iPhone XS Max, and iPhone XR will all get performance management functionality with the iOS 13.1 update scheduled for September 24. The company says the feature will only work if the iPhone really needs it, and the functionality is similar to what iOS 12.1 brings to the iPhone 8, iPhone 8 Plus, and iPhone X. He adds: ” The effects of performance management on these newer models may be less noticeable due to their more advanced hardware and software design. . “

“It works by looking at a combination of device temperature, battery state of charge, and battery impedance. Only if these variables require it, iOS will dynamically manage the peak performance of certain system components, such as CPU and GPU, in order to avoid unexpected shutdowns. As a result, the device’s workloads self-balance, allowing for a smoother distribution of system tasks, rather than rapid and larger spikes in performance all at once. In some cases, a user may not notice any difference in the daily performance of the device. The level of perceived change depends on the degree of performance management required for a particular device, ”the support page explains.
