Apple didn't hide it. It was in changelog of some iOS version. They just didn't make it a big deal. Honestly I don't think that this is a big deal. Today's iPhone is absurdly powerful. This speed is not needed for average user, so he won't notice this downgrade.

Here’s the full release notes (from https://support.apple.com/kb/DL1893?locale=en_US):

”iOS 10.2.1

iOS 10.2.1 includes bug fixes and improves the security of your iPhone or iPad.

It also improves power management during peak workloads to avoid unexpected shutdowns on iPhone.

For information on the security content of Apple software updates, please visit this website: https://support.apple.com/HT201222 ”

They mention it, and an investigative journalist could have dug deeper based on it, but as is, that’s fairly vague.

Huh. That changes things a bit. I did not know about this. Do you have a link to relevant material?

It's a pretty hollow defense, because users are clearly not reading changelogs, and a reasonable person would obviously understand that a consumer's response to a poorly performing phone is conclude that it's time to buy a new one.

And my understanding is that there is no explicit mention in the changelog, just an opaque mention of new power management feature. But again, no one reads changelogs and the folks at Apple know that.
