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), Apple Watch Series 4 (GPS + Cellular), or

Apple Watch Series 5 (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 can’t 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 .
