“Apple Makes iPhones with Older Batteries Run Slower”
This controversy popped up in late 2017 when reports surfaced that Apple was deliberately slowing down iPhones. A lot of misinformation was created about how and why this was happening, and many people started blaming older batteries. The truth is a lot more complicated.
First, it wasn’t aging batteries that caused the issue, but rather new “features” that Apple added to iOS. These features – and Apple indicated that bugs were also affecting how they worked – were designed to help save power by “smoothing” performance, which slowed down some iOS processes.
The problem was that iPhones with older batteries had lost some of their charge or weren’t prepared for the new feature, and power smoothing was triggered when it shouldn’t have been.
Apple addressed all this by offering discounts on iPhone battery replacements and updating iOS in later versions to avoid the issue. It’s no longer a problem for iPhone users.
