1, may not use the standard charger and data cable, it is recommended to try after the standard configuration. Charging with a mobile power supply, or connecting to a computer USB port will also charge slowly.

2. When charging, the charger, data cable, and mobile phone charging interface are not in contact, or there is dust in the connector and jack, which may lead to slow charging. You can plug and remove the charger several times, wipe it with alcohol or clean it with a brush. If alcohol wipe, need to wait for alcohol to dry, and then re-charge.

3, in the charging process, the temperature of the mobile phone will change to a certain extent, especially when charging the mobile phone also runs some programs, the temperature will rise significantly, the charging current will gradually decrease when heating, the charging speed will slow down until it is full. It is recommended to wait until the temperature of the phone decreases before charging it, and close the background applications.
< br >
4, it is recommended not to use the mobile phone when charging, especially close the video, games and other applications with high power consumption, otherwise part of the charger input current to offset the power consumption of the mobile phone, the current to the battery will be reduced, and the charging speed will be slow.
< br >
5, usually the mobile phone battery is low charging speed is relatively fast, when the charging reaches more than 80%, the battery power is close to full power. In order to ensure the safety of use and extend the battery life, when the battery is quickly full, the charging current output of the charger will gradually decrease, and the charging speed will slow down until it is full.

Not using the standard charger and cable may affect the charging speed
< br >
Due to different brands and power chargers, there are differences in charging specifications and fast charging principle, mixed charger\/data cable may lead to slow charging or no fast charging.
< br >
Please check whether the USB connector of the data cable and the USB port of the phone are clean. If dust is found, it is recommended to clean it with a brush and then charge it again for confirmation.
< br >
Other factors that affect the charging speed:
< br >
The charging speed is inconsistent at different stages of charging.
< br >
Cell phones charge slowly when they are nearly full
< br >
High or low ambient temperature will affect the charging speed.
< br >
Slow or unable to charge at low temperatures
< br >
The ambient temperature is high, and the phone charges slowly when it is hot
< br >
The use of mobile phones affects the charging speed, the more you use, the slower the charging.
< br >
Charge slowly when charging while using
< br >
Charge does not enter the electricity, the charging power does not increase, or even decrease
