Charging the battery
The new battery will reach the optimal efficiency when it has undergone several continuous complete charges and
discharges.
When the battery is low, charge it in time. Over-discharge can damage the battery. After the battery is charged
full, cut the connection of the charger with the AC power supply and then the connection of the charger with the
mobile phone.
Follow the below diagram to connect the charger. During charging, the battery capacity icon on the screen will
report the charging process. After the battery is full, the battery icon will be full.
Slight heat formation during charging is normal.
Warning: when a travel charger and its accessories are used to charge the battery, please check first that they are
original or recognized by the manufacturer. The use of other accessories may damage your mobile phone and
cause risks! Always use them indoor and in dry places.
Warnings on the use of the battery
The performance of the battery is affected by many factors, including network settings, signal strength, work
temperature, chosen and used functions or settings as well as phone accessories, tone, data or other applications.
For optimal performances, please follow the rules below:
New batteries or a battery unused for a long time need a longer charging time. The standard voltage scope
for the battery is 3.6V-4.2V.
During charging, keep the battery around room temperature.
With time passing by, the battery will gradually be worn and thus needs longer time to charge. This is
normal. However, after normal charging, if call duration decreases while charging time increases, you will
need to buy another battery from the original manufacturer or one authorized by the manufacturer. The
battery of lower quality can damage your mobile phone and cause danger!
If the phone is overused at low battery level, it might need a longer time for the charging indicator to be shown on
the screen.
Note: please dispose the battery according to the local regulations. Try to recycle the battery if possible. Do not
treat the waste battery as common waste.
Warning: do not throw the battery into fire so as to prevent fire hazard. The broken battery may cause explosion.
Warning:
Charging the mobile phone by improper means can cause to explosion. Always refer to the related
regulations for the disposal of the battery.
