Battery charging tips and precautions

Use only approved chargers, batteries, and cables. Using

an unapproved or incompatible power adapter, charger, or

battery may damage your phone, shorten its lifespan, or

cause a fire, explosion, or other hazards.

• Avoid using your phone when it is charging. Do not

cover your phone or the power adapter.

• Connecting the charger improperly may cause serious

damage to the phone. Any damage caused by misuse

is not covered by the warranty.

• If the AC power supply is of a lower voltage, then a

longer charging time may be needed.

• If nonstandard chargers such as computers are used

for charging, then a longer charge time may be needed.

• Fully charge the battery before first using the phone and

disconnect the charger immediately after the first charge

is completed.
