iPhone 15 users will be able to check their battery's cycle count for the first time, according to information shared on X (formerly Twitter). ...
Why exactly is that not a feature that can be expanded to every currently supported iPhone?
Especially since you can already check it in the data logs on older phones.

The implication that having a cycle count on your phone is going to drive upgrades is bizarre.
"Hey, what made you decide to get the new iPhone?"
"It has battery cycle counts!"
I can see it already.
Conversely, I could see people upgrading because their battery cycle count is high , making them feel like the performance is degrading.
May it be like miles in used cars? You'd see a big number and you'd be more likely to buy new instead. Or replace a battery if it even comes to that.
