Getting started
•
If your phone has been running for long periods of time, especially in hot
environments, heat may be pushed to the surface of the phone. If your
phone is overheating, cease using it immediately and unplug it from any
power source to let it cool down. Do not hold on to the phone for too long
to avoid burn injuries.
•
Use the original battery, power adapter, and USB cable to charge your
phone. Using third-party accessories may reduce your phone performance
or pose security risks. When your phone is charging, do not operate it or
cover the phone or power adapter with any object.
•
The time required to fully charge the battery depends on the ambient
temperature and age of the battery.
•
If your phone is very low on power, it plays an alert tone and displays a
message. If the battery level is extremely low, your phone automatically
powers off.
•
If the battery power is depleted, you may not be able to power on your
phone immediately after you begin charging the battery. This is normal.
Allow the battery to charge for a few minutes before attempting to power
on your phone.
