Apple Admits to Secretly Slowing Down iPhones, Explains Why

Apple has issued an official statement to address recent speculation that it's been secretly slowing down older iPhones.

Here's the statement:

“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.”

For those unaware, here's the backstory. In 2016, iPhone 6s owners began complaining that their devices were unexpectedly shutting down. Apple issued a 'small' battery recall claiming a manufacturing defect.

"We found that a small number of iPhone 6s devices made in September and October 2015 contained a battery component that was exposed to controlled ambient air longer than it should have been before being assembled into battery packs. As a result, these batteries degrade faster than a normal battery and cause unexpected shutdowns to occur. It's important to note, this is not a safety issue."

Despite the recall, there were still iPhone 6s owners experiencing problems. Apple then issued a software update three months later that was able to mysteriously fix unexpected shutdowns for most users.


That was pretty much the last we heard about the issue until earlier this month when a reddit user noticed that benchmark scores were significantly higher after swapping the battery on an iPhone 6s.

The report led to some analysis by John Poole, founder of Geekbench, which appeared to confirm that Apple was slowing down iPhone 6s and iPhone 7 devices based on the condition of their battery.

Apple's statement today confirms that yes, it is intentionally slowing down iPhones but only when it attempts to draw more power than the battery can provide. It lays the blame on the nature of lithium-ion batteries. As batteries age they have increased internal series resistance that limits the amount of power you can pull out of them. What the company does not explain is why iPhone 6 and 6s weren't designed with enough headroom to prevent this from happening in such a short period of time. Given the recall and subsequent software update, it's fairly clear that this was an unexpected problem. Shouldn't we have seen the same issue will all previous iPhone models?

What will likely raise the most ire isn't the slowdown itself but the lack of transparency surrounding it. Customer's should know if the performance of their device is taking a hit due to its battery condition so that they can have the opportunity to replace it. Additionally, the shortsightedness of implementing this change in secret will likely contribute to the narrative that Apple slows down its devices purposely to drive upgrades.

Developer Marco Arment recently tweeted, "For years, we’ve reassured people that no, Apple doesn’t secretly slow down their older iPhones to make them buy new ones. If this must be done, it should be a setting. If it’s on by default, the user should be alerted the first time it happens. The reputation damage from secretly slowing down old iPhones, regardless of the reason, will likely linger for a decade."

Daring Fireball's John Gruber also addressed this belief saying, "I know for a fact that the widely-held belief that Apple booby-traps two-year-old iPhones drives Apple employees — ranging from engineers to senior executives — nuts, because the truth is the opposite. They really do knock themselves out trying to build and maintain products with lasting value."
