Battery Safety Guidelines
• Do not disassemble or open the battery.
• Do not crush, bend, deform, puncture, or
shred the battery.
• Do not attempt to insert foreign objects into
the battery.
• Do not immerse the battery or expose it to
water or other liquids. Even if a battery
appears to dry out and operate normally,
internal parts can slowly corrode and pose a
safety hazard.
• Always keep the battery between 15°C and
25°C (59°F and 77°F). Do not expose the
battery to extremes of temperature (heat or
cold), fire, or other hazards such as a cooking
surface, iron, or radiator.
• Never use any damaged battery.
• Only use the battery for its intended phone.
• Only use the battery with a qualified charger.
Use of an unqualified battery charger may
present a risk of fire, explosion, leakage, or
other hazard. If you are unsure about
whether a charger is qualified, contact
customer support.
• Do not short-circuit the battery or allow
metallic conductive objects—such as
keys, coins, or jewelry—to contact the
battery’s terminals.
• Replace the battery only with another qualified
battery. Use of an unqualified battery may
present a risk of fire, explosion, leakage, or
other hazard. If you are unsure about whether
a replacement battery is compatible, contact
customer support.
• Promptly dispose of used batteries in
accordance with local regulations and
recycle if possible. Do not dispose as
household waste.
• Supervise all battery usage by children.
• Avoid dropping the phone or battery. If the
phone or battery is dropped, especially on a
hard surface, an internal short-circuit can
occur and pose a safety hazard. If you
suspect battery damage, take it to a service
center for inspection.
• Improper battery use may result in a fire,
explosion, or other hazard.
Common Causes of Battery Drain
• Playing games or using the Web.
• Keeping backlighting on.
• Operating device far away from a base
station or cell site.
• Using data cables or accessories.
• Operating when no service is available, or
service is available intermittently.
• High earpiece and ringer volume settings.
• Repeating sound, vibration, or lighted alerts.
