Device Information
About the AMOLED Display
By default, the watch settings are optimized for battery
life and performance (
Tips for Maximizing the Battery Life,
).
Image persistence, or pixel "burn-in," is normal behavior
for AMOLED devices. To extend the display life, you
should avoid displaying static images at high brightness
levels for long time periods. To minimize burn-in, the
D2 Mach 1 display turns off after the selected timeout
(
Changing the Screen Settings, page 77
). You can turn your
wrist toward your body, tap the touchscreen, or press a
button to wake the watch.
