Apple posted a help document on Thursday that outlines exactly what its controversial “power management” feature does.
Apple apologized on Thursday because some customers are upset that it slows down iPhones with older batteries.
Older iPhones can take longer to launch apps, may display choppy scrolling, and can have dimmer screens and quieter speakers.
According to Apple, it’s a “power management” feature that helps protect the iPhone from random shutdowns and damage to its components.
If you’ve got an iPhone that’s getting on in age you may have noticed it runs slower after the latest updates.
That’s because Apple slows down older iPhones when they have aging batteries. According to Apple, software updates throttle older iPhones because their batteries are “less capable of delivering peak energy loads,” according to an apology the company issued on Thursday.
