Now it seems make sense that Apple in Now it seems make sense that Apple in iOS 10.2.1 introduced an update to fix a bug that was causing iPhone 6s models to shut down unexpectedly, and a result of the update is it slows down these devices. Apple says this feature has been implemented for iPhone 6, 6 Plus, 6s, 6s Plus, SE, as well as iPhone 7 and 7 Plus.

"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."

According Apple's According Apple's battery replacement guidelines . The iPhone battery is designed to retain 80% of its original capacity at 500 complete charge cycles. A defective battery that does not meet those parameters can be replaced for free for customers who have AppleCare+ or who have devices still under warranty. As for out of warranty customer, Apple charges $69 plus $6.95 in shipping.

Apple has now responded to the comment that there's been speculation that the company is throttling the performance of older iPhones with degraded batteries. In a statement to TechCrunch , Apple says they are 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."There's nothing Apple can do to prevent from Lithium-ion batteries degrade over time , so it uses power management techniques to attempt to prolong the life of the iPhone and its battery. The Cupertino company says 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.
