Low power mode is something different, and iOS has that too. The problem here isn't that iOS isn't just trying to conserve power to last a bit longer. At some point the battery physically can't deliver the current required to run the CPU at max speed. At that point, the phone battery settings screen says something like "Battery Service Required". For some reason a lot of people get annoyed when their phone needs service. It's understandable, but I really don't see what Apple should do about it. When a car's battery needs to be replaced, people don't go complaining how their car is suffering from planned obsolescence, they just replace the battery.
