1, no use of standard charger and data cable;
2, charging charger, data cable, mobile phone charging interface is not in contact with good, may lead to slow charging, unable to charge the phenomenon, please plug and remove the charger several times;
3, please check whether the joint and jack are clean, if found dust, it is recommended to wipe with alcohol or clean with a brush. If alcohol wipe, need to wait for alcohol to dry, then re-charge to confirm;
4, 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.
5, the summer weather is hot, the ambient temperature is high, the mobile phone heat dissipation is difficult, so compared with the ambient temperature in winter, the charging speed will be relatively slow, this is a normal phenomenon;
6, it is recommended not to use the mobile phone when charging, especially please close the video, games and other applications with high power consumption. Because if the mobile phone is charging to play games, watch videos and surf the Internet, part of the charger input current needs to offset the screen and other mobile phone hardware consumption of electricity when in use, resulting in the battery charging current will be reduced, the charging speed will be slow.
This is probably because of a problem with the flash suit. If you need to change the charging kit, it will charge faster.
