Charging the Battery
The lithium battery can be used directly after being taken out from the package. To make the
battery always in its best condition, please exhaust the capacity of the battery and then fully
recharge it for the first three times.
1. Insert the charger to the mobile phone through USB interface;
2. Plug the charger into 110V/220V power socket;
3. When the mobile phone is powered on, the battery capacity bar
on up-right corner of the screen keeps scrolling during charging;
when the mobile phone is powered off, there will be charging indication on the
screen during charging. If the mobile phone is used excessively without enough
capability, the charging indication will not immediately appear on the screen of the
mobile phone when charging starts, and the mobile phone might not be powered on
within a few minutes after the charging starts;
4. When the mobile phone is on, the battery is fully charged as the battery capacity bar
on the up-right corner of the screen is full and doesn't flicker any longer. When the
mobile phone is off, the battery is fully charged as fully charged picture appears on the
screen. During the charge, your mobile phone and charger may normally become hot;
5. Please disconnect the charger from your mobile phone and the socket when the
charging is completed.
