Magnetic Charging Cable and Magnetic Charging Dock Discoloration of the charging
surface of the Apple Watch Magnetic Charging Cable and the Apple Watch Magnetic
Charging Dock may occur after regular use due to dirt and debris that come in contact
with the magnetic surface. This is normal. Cleaning the magnetic charging surface may
reduce, or prevent, such discoloration, and will help to prevent damage to your charger
and Apple Watch. To clean the charging surface, disconnect the charger from both
Apple Watch and the power adapter and wipe with a damp, nonabrasive cloth. Dry with a
nonabrasive, lint-free cloth before resuming charging. Do not use cleaning products
when cleaning the charging surface.
Operating temperature Apple Watch is designed to work best in ambient temperatures
between 32° and 95° F (0° and 35° C) and be stored in temperatures between -4° and
113° F (-20° and 45° C). Apple Watch can be damaged and battery life shortened if
stored or operated outside of these temperature ranges. Avoid exposing Apple Watch to
dramatic changes in temperature or humidity. If the interior temperature of Apple Watch
exceeds normal operating temperatures (for example, in a hot car or in direct sunlight for
extended periods of time), you may experience the following as it attempts to regulate its
temperature:
Charging may slow or stop.
The display may dim.
A temperature warning screen may appear.
Some data transfer may be paused or delayed.
Some apps may close.
On Apple Watch Series 3 (GPS + Cellular) or Apple Watch Series 4 (GPS + Cellular),
you might not have a cellular connection or you might not be able to make or receive
calls. Normal cellular functionality resumes after Apple Watch cools. However, you
can still make emergency calls.
Important: You may not be able to use Apple Watch while the temperature warning
screen is displayed. If Apple Watch canʼt regulate its internal temperature, it goes into
Power Reserve or a deep sleep mode until it cools. Move Apple Watch to a cooler location
out of direct sunlight and wait a few minutes before trying to use Apple Watch again. For
more information, see the Apple Support article
