Note:
After the phone has run out of battery, we recommend that you
recharge the battery on time. If you do not recharge the battery
within two days, the phone may enter the slow charging mode. When
you recharge the battery, there may be no display temporarily. After
about 10 minutes, the charging indicator icon is displayed on the
screen of the phone. If you do not recharge the battery for more than
two days, the battery may enter the deep discharge protection state.
Thus, in order to get the battery into normal charging mode quickly,
we recommend that you charge the battery on an adapter to activate
the battery for charging, and then charge the battery with the phone.
Alternatively, you can charge the battery with the adapter.
Do not change the parts and accessories of the battery yourself or
take off the battery cover for safety.
Use only original batteries and charging devices. Otherwise you may
risk serious damage to health and property.
The temperature recommended for charging a battery is 10°C to
