Hello, there may be several reasons:
1. Insufficient charger power: If the power of the charger used is not large enough, it will lead to slow charging.
2. Poor quality of USB interface: If the quality of USB interface is not good, it will lead to poor current transmission, thus affecting the charging speed.
3. Mobile phone software problems: Sometimes, mobile phone software may affect the charging speed, so you can try to close some unnecessary applications.
4. Loose charging cable: If the charging cable is in poor contact with the phone, it will cause the charging speed to slow down.
5. Aging battery: If the phone battery is aging, it will cause the charging speed to slow down.
It doesn't seem sufficient.
Because the nova9 mobile phone shows fast charging, but the actual charging speed is slow, which may be caused by the following reasons: 1. Insufficient charger power; 2. Aging of charging cable leads to loss; 3. The aging battery of the mobile phone affects the charging speed.
If the problem of slow charging speed does exist, it can be solved by replacing the charger, charging cable or battery.
Fast charge display but slow charge. Because the fast charge means that the output voltage and current of the charger are high, the charging speed of the mobile phone can be accelerated, but the actual charging speed is also affected by the phone power, battery health, charging line quality and other factors.
If the phone battery is already high or the battery aging leads to reduced charging efficiency, or the charging line is loose or damaged, it will lead to slow charging. In addition, some mobile phone charge management software will also affect the charging speed, so it is recommended to check whether the phone and the charging line are normal and turn off some unnecessary charge management software.
Your fast charge is not very fast, because if you charge fast, 18 watts is a fast charge. If it is 65 watts of charging will be quite fast, maybe your mobile phone fast charge is only the lowest fast charge.
