>> But I think Apple needs to have iOS alert you that it's slowing your phone down because the battery has degraded.

I see so many Mac laptops with the service battery warning on. People won't replace them until they have to, even to the point of the laptop needing to be connected to the wall outlet to run.

It's exactly because they don't magically lose CPU speed because of battery issues; people can adjust to failing batteries if the device remains useful (even for phones with fixed batteries, powerbanks exist).

With iPhones, Apple decided to make the device less useful instead.

Mac laptops actually used to work in a similar way, however I'm not sure if that is still the case.

If you had a dead battery (or no battery), your CPU frequency would be limited because the AC adapter could not supply enough power on it's own

The link is dead, but it was documented on Apple's support site: http://support.apple.com/kb/HT2332
