Battery
Your phone comes with a rechargeable Lithium-ion battery and is
designed to use only manufacturer-specified original batteries and
accessories. Battery performance depends on many factors, including
network configuration, signal strength, the temperature of the
environment in which you operate your phone, the features and/or
settings you select and use, items attached to connecting ports, and
your voice, data, and other program usage patterns.
