Use only approved chargers, batteries, and cables. Using
an unapproved or incompatible power adapter, charger, 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.

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.
