The performance of the battery is affected by many
factors, including radio barrier network settings, signal
strength, work temperature, chosen and used functions
or settings as well as phone accessories, data or other
applications.
For optimal performances, please follow the rules below:

New battery or the battery has been idle for a long
time, need charging for longer time also. The standard
voltage scope for the battery is 3.6V-4.2V.

While charging, keep the battery at room
temperature or similar temperature.

As time pass by, the battery will gradually be worn
and thus need longer time to charge. This is normal.
However, after normal charging, if call duration decreases
but charging time increases, you need to buy another
battery from the original manufacturer or authorized by
