Always‑On Display: what it is and why it changes everything

AOD affects readability, battery, burn‑in risk, and what “good design” means on a wrist-sized screen.

What AOD is (in plain language)

Always‑On Display means your watch shows a simplified version of the watchface even when you’re not actively looking at it. It’s designed to use less power, and it often changes how frequently the display updates.

Why it changes the feel of a watchface

A face that looks gorgeous in interactive mode can become unreadable in AOD if it relies on subtle gradients, low contrast, or tiny details. In AOD, simple and bold usually wins.

Design rule: Your AOD should be readable in one glance, in daylight, without motion.

Battery & burn‑in realities

  • Bright pixels cost battery (OLED displays especially).
  • Static elements in the same location increase burn‑in risk over time.
  • Motion in AOD is usually a bad deal: higher power, minimal benefit.

What to look for in a good AOD watchface

  • A dedicated AOD design (not just “same face but dimmer”)
  • Reduced clutter (time first, essentials second)
  • No seconds in AOD
  • Good contrast and legible fonts

Animated waves look good on this watchface, but they can drain battery if you have AOD set on.
