Apple Slows Down Older iPhones

Apple confirms iPhones with older batteries will take hits in performance

The Verge – By: Tom Warren and Nick Statt – “Reddit users have noticed that Apple appears to be slowing down old iPhones that have low-capacity batteries. While many iPhone users have experienced perceived slowdowns due to iOS updates over the years, it appears that there’s now proof Apple is throttling processor speeds when a battery capacity deteriorates over time.

Geekbench developer John Poole has mapped out performance for the iPhone 6S and iPhone 7 over time, and has come to the conclusion that Apple’s iOS 10.2.1 and 11.2.0 updates introduce this throttling for different devices. iOS 10.2.1 is particularly relevant, as this update was designed to reduce random shutdown issues for the iPhone 6 and iPhone 6S. Apple’s fix appears to be throttling the CPU to prevent the phone from randomly shutting down. Geekbench reports that iOS 11.2.0 introduces similar throttling for low iPhone 7 low-capacity batteries.

Some Reddit users report that replacing their batteries has returned performance and CPU clock speeds back to normal. The reports are particularly troubling because any perceived slowdowns by iPhone users might tempt owners to upgrade their entire device instead of replace the battery. ‘This fix will also cause users to think, ‘my phone is slow so I should replace it’ not, ‘my phone is slow so I should replace its battery,” says Geekbench’s John Poole.

So it’s true Apple intentionally slow down old iPhones. Proof: My iPhone 6 was bought 3years ago and recently got really slow. APP ‘CPU DasherX’ shows iPhone CPU is under clocked running at 600MHz. After a iPhone battery replacement. CPU speed resumed to factory setting 1400MHz.

When reached for comment, Apple basically confirmed the findings to The Verge, but disputes the assumed intention:

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. The same is true of devices running in extremely cold or hot weather, as evidenced by a recent kerfuffle with the iPhone X shutting down randomly in freezing temperatures.

It all makes sense. As battery life degrades, a smartphone’s ability to achieve the same performance with less efficient battery use degrades as well, and Apple has released updates to address that problem as best it can and avoid embarrassing device malfunctions or even potentially dangerous component failures. However, the company isn’t doing itself very many favors by being a bit opaque. It’s clear that controversies like this — underpinned by conspiracy theories around planned obsolescence — sprout up because there is a lack of communication between device manufacturers like Apple and consumers.

It’s also clear that Apple, which makes its devices hard to open and repair, could do a better job helping consumers understand the benefits of battery replacement. That’s something the company seems less inclined to do when it might mean forgoing the sale of a new iPhone every 12 to 24 months.”
