Battery Standby and Talk Time
Standby and talk times will vary depending on phone
usage patterns and conditions. Battery power
consumption depends on factors such as network
configuration, signal strength, operating temperature,
features selected, frequency of calls, and voice, data, and
other application usage patterns.
Battery Precautions
• Avoid dropping the cell phone. Dropping it, especially on a hard
surface, can potentially cause damage to the phone and
battery. If you suspect damage to the phone or battery, take it
to a service center for inspection.
• 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'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 network operator.
• Follow battery usage, storage and charging guidelines found in
the user’s guide.
• Battery charging time depends on the remaining battery charge
and 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.
