1 Start Using
Battery
Before using your phone for the first time, please follow the
instructions below to charge your battery completely. Do not
overcharge, which will damage the battery and shorten its life. When
not in use, unplug the charger from both your phone and the
electrical outlet.
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.
1.1 Uninstallation and installation of battery
 Push the back cover of the phone upward as shown below and
remove.
 Pull out the top of the battery and remove.
