Battery
Your device comes with a rechargeable Lithium-ion or Lithium-ion polymer 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 device, the features and/or settings you select and use,
items attached to connecting ports, and your voice, data, and other program usage patterns.
