in shortage of battery or not used for a long time, the screen may not display the
charge indicator immediately.
When the battery level indictor changes from charging symbol to full level indicator,
it means charge has been finished. If the battery is charged in power-off condition,
the stop of charge animation indicates the charge has been finished. Generally the
whole charge process needs 2~3 hours (Please charge the battery for 6~8 hours
for the first three times). During the charge process, your phone, battery and
charger may become hot, and this is a normal phenomenon.
Please disconnect the charger with the phone and the power outlet when charging
finished.
Warning:
Please put the phone at the ventilated place with temperature between ＋5℃~＋
40℃. Please use charger provided by the provider. Using unauthorized charger
may cause danger and violate the authorization and warranty rules of the phone.
Please charge the battery in time when your phone automatically powers off or
displays a warning "battery is low".
