Annoying low battery alert

Hi there. The warning of "battery low to 20% 10% etc..." on my iPhone 7 version 14.6, my iPad Air 2 and my MacBook Pro version MacOS Big Sur 11.2.3 is very annoying. It is directly invasive and cuts off whatever activity I am doing. I don't want that warning anymore. Has no sense at all. How can I disable it?
