Battery safety
This information is based on fully charged batteries.
Depending on how you use your phone, actual
operation time may vary and may be shorter than
declared. Standby time will be reduced in the following
conditions:
• When you use the additional features on your phone
such as writing and storing messages, playing
games, and connecting to the internet
• If you are frequently out of the service area
• If you are out of the service area for a long period of
time
•
If you use Talk mode repeatedly
The battery can be charged and discharged hundreds of
times, but it will eventually wear out. When the
operation time for both talk mode and standby mode is
reduced by about half, it is time to buy a new battery.
Precautions when using batteries
• Never use a 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’s base
station, it uses less power. Talk and standby time
are greatly affected by the signal strength on the
cellular network and the parameters set by the
service provider.
• Battery charging time depends on the remaining
battery charge, the type of battery, and the charger
used. The battery can be charged and discharged
hundreds of times, but it will gradually wear out.
When the operation 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.
