why most electronic devices perform worse and worse as the battery life shortens? shoudln’t they always perform at peek as long as there is battery?

Batteries are not like power plants that provide a consistent 110 Volts to your house. Batteries produce their electricity (voltage and current) from a chemical reaction, and as the battery ages that reaction goes slower, so the voltage and the current from the battery decrease. So your device gets less electricity to work with.
It’s like trying to generate electricity by [pedaling](https://kicanada.com/resources/image/18/7f/c.jpg), when you get tired there’s less electricity.
