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.
Apple is effectively saying that it’s not slowing down older iPhones just to urge people to upgrade to newer devices. Rather, the company says it’s addressing an issue with devices containing older lithium-ion batteries that results in unexpected shutdowns. Because those older batteries are incapable of handling peak current draws with the same effectiveness of iPhones with newer batteries and more efficient processors, they run the risk of the device powering down to prevent damage to its internal components.
Not surprised by this. We all knew Apple was doing something like this. Apple just needs to be more open and telling it’s users of what it’s doing.
