iPhone Operating Temperature
If the interior temperature of iPhone exceeds normal operating temperatures, you may
experience the following as it attempts to regulate its temperature:
iPhone stops charging Â
the screen dims Â
the cellular signal is weak Â
a temperature warning screen appears Â
Important: You cannot use iPhone while the temperature warning screen is displayed,
except to make an emergency call. If iPhone can’t regulate its internal temperature, it
goes into deep sleep mode until it cools. You cannot make an emergency call when
iPhone is in this mode. Move iPhone to a cooler location and wait a few minutes
before trying to use iPhone again.
