It’s called downclocking or underclocking
Apple has come clean. They have admitted slowing down old iPhone devices with low-capacity batteries. They say it’s a way of protecting the devices’ components.
Apple users have always wondered whether their older phones are slowed down by the ‘suits’ to force them to upgrade to newer models. Apple says the slowing of the phone’s central processing unit (CPU) does take place. But it isn’t for the money grab.
The act is called “downclocking” or “underclocking.”
A study by a Reddit user claimed Apple slowed phones when the battery has diminished charge capacity. Apple replied and said this was due to a need to protect electronic parts.
Apple’s goal is to deliver the best experience
Apple’s batteries become less able to provide the top levels of electrical current needed. The problems with peak current draws especially occur when batteries are cold or low on charge. In a statement, they noted this “can result in the device unexpectedly shutting down.”
“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.”
“Our goal is to deliver the best experience for customers.”
