Care and Maintenance
 Battery Care
▪ Your device is powered by a rechargeable battery. When the power is weak, please charge the battery.
In order to extend the lifespan of the battery, consume first the power before recharging.
▪ When not in-use for longer time, take out the battery from the phone.
▪ Do not leave your phone charging for longer period other than specified. Overcharging may shorten its
lifespan and may damage the battery.
▪ Extreme temperatures can affect the performance of the battery.
▪ Use the battery only for its intended purpose. Never use any charger or battery that is damaged.
▪ Do not short-circuit the battery. Accidental short-circuiting occurs when a metallic object such as coin,
clip, or pen causes direct connection of the positive (+) and negative (-) terminals of the battery. (These
look like metal strips on the battery.) Short-circuiting the terminals may damage the battery or the
connecting object.
▪ Leaving the battery in hot or cold places, such as in a closed car in summer or a freezer in winter
conditions, will reduce the capacity and lifetime of the battery. Always try to keep the battery between
59°F and 77°F (15°C and 25°C). A hot or cold battery may not function temporarily, even when the
battery is fully charged.
▪ Battery performance is particularly limited in temperatures below freezing.

when possible. Cellphones are not considered household waste.
