Recently there’s been speculation that Apple is throttling the performance of older iPhones, including the iPhone 5, 5S, 5C, 6 and 6S with degraded batteries, leading to resurgence of accusations that Apple is deliberately slowing down older iPhones that aren’t operating at peak battery performance.
Apple says it is aiming to smooth out the high power draw peaks that can result in shutdowns and other problems in older devices to “deliver the best experience for customers.”
Lithium-ion batteries degrade over time by nature, and there’s nothing Apple can do to halt the process, so it uses power management techniques to attempt to prolong the life of the iPhone and its battery. Apple isn’t denying that iPhones with older batteries can sometimes see slower performance, but power management is not a feature that’s been implemented to force users to upgrade by deliberately slowing devices.
Apples says “Our goal is to deliver the best experience for customers, which includes overall performance and prolonging the life of their devices. Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components.
Last year we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting down during these conditions. We’ve now extended that feature to iPhone 7 with iOS 11.2, and plan to add support for other products in the future.”
