Battery impact of Reminders
Reminders is a small SwiftUI surface. Reminders can appear beside events so the next action is visible. Disable it if you want the lightest possible notch.

Live polling and media artwork cost more than a static chip. Reminders should sleep when unused.
How to lighten it
Turn off unused live activities in Settings so Reminders is not in the stack all day.
