It's not only to make them run longer - they're reducing the peak demand on the batteries to avoid spontaneous shutdown when the aged battery can't handle the load.

This seems like a good idea, and it appears to be well executed (ie it's not apparently based just on age or milage like a crappy car maintenance reminder), but Apple should probably have something in iOS that tells people their phone is running slow because the battery is 2 years old.

THIS MAKES SO MUCH SENSE. I always thought I was going crazy, thinking my increasingly "old" phone seemed slow. This is really irritating and disingenuous on Apple's behalf - as said above, they should at least add a switch.

The bigger effect is probably how software is developed. Most devs have a shiny new phone on their desk, we make it fast enough and then stop, therefore an older phone will appear to be slower because the app is still fast on our devices.

QA will test on a older phone but most companies don’t have tight performance targets so what used to be 60 FPS is now 45 and what used to be a 200 ms load is now 250 ms.

The difference is imperceptible during dev because each new feature shaves a few FPS and adds a few ms.

It does say in iOS that your battery needs to be replaced [1]. Everyone keeps saying they never told anyone about this but they basically announced it to the press with a statement (as well as the notice in iOS) when iOS 10.2.1 was released [2].
