Using the Batteries
The battery provided with the phone is a Lithium slim battery.
Precautions When Using Batteries
Never use any charger or battery that is damaged in any way.
Use the battery only for its intended purpose.
If you use the phone near the network base station, it uses less power ; talk and standby times are greatly
affected by the signal strength on the cellular network and the parameters set by the network operator.
Battery charging times depend on the remaining battery charge, the type of battery, and charger used.
The battery can be charged and discharged hundreds of times, but it will gradually wear out. When the
operation time (talk time and standby time) is noticeably shorter than normal, it is time to buy a new
battery.
If left unused, a fully charged battery will discharge itself over time.
