My Phone Seems to Turn Off by Itself
Your phone has a power-saving feature that’s set to
turn off the screen if it has been idle for one minute.
You can change the auto-shut off interval (see “Set the
Interval for Turning the Screen Off Automatically” on
page 175).
If you restart your phone, any wireless services are
automatically turned on if they were on before the
restart. However, if the phone can’t determine if a
wireless service was on before the restart, that service
does not automatically turn on (see “Turn the Phone
On/Off” on page 18).
If the problem persists and you’re using third-party
applications, see “Third-Party Applications” on
page 261 for additional suggestions.
