Yes, you were right. Apple does intentionally slow down iPhones as they get older. And the company has finally admitted it. The disclosure came after customers, specifically on Reddit, pointed out that replacing the battery on an old iPhone appeared to make it run, much smoother and faster.
Yes, you were right. Apple does intentionally slow down iPhones as they get older. And the company has finally admitted it. The disclosure came after customers, specifically on Reddit, pointed out that replacing the battery on an old iPhone appeared to make it run, much smoother and faster.
But the reason for this move might surprise you. Apple stated that the company does this only to make its iPhones with ageing batteries run smoother and also, much faster.
Apple acknowledged that the company does take some measures to reduce power demands - which can have the effect of slowing the processor - when a phone's battery is having trouble supplying the peak current that the processor demands. This is mainly because, all lithium-ion batteries, not just those found in Apple products, degrade and have problems supplying the big bursts as they age and accumulate charging cycles. The problems with peak current draws can also occur when batteries are cold or low on charge.
Apple confirmed the findings to The Verge and said, “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.”
When an iPhone's processor makes a big current draw from a flagging battery, the battery can deliver the current in spikes that can potentially damage the phone's electronics. As a result, iPhones would suddenly shut down to protect the pricey processor from being damaged by the power spikes.
The company says, “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.”
A Reddit users points out that replacing an iPhone battery, leads to “returned performance and CPU clock speeds back to normal,” according to the report. However, this might not work for everyone, though, as battery wear and tear varies.
