Not necessarily bad, but something's wrong.
< br >
Mobile phone does not display fast charge reasons:
< br >
1, the charging head used is not the official original, in the case that the charging head output current is not enough, the mobile phone can not enter the fast charge mode;
< br >
2, the quality of the charging cable used does not meet the requirements, it is recommended to replace the randomly adapted charging cable, and then try again;
< br >
3, for system reasons, there may be some bugs that cause the phone to not automatically enter the fast charge mode, at this time, re-plug the charging connector will be better;
< br >
4, if there is no problem in the use of charging head and charging cable, it may be the mobile phone hardware causes the fast charge mode failure, it is recommended to send the mobile phone to the after-sales service to deal with it.
< br >
Suddenly, it is not fast charging or does not show the sign of fast charging, most of the data line is broken, and there will be such a situation when the contact is unstable. Basically, you just change the cable.
< br >
The phone cannot enter the fast charge mode. Please try the following methods to solve the problem:
< br >
1, please check the output parameters of the charger, the device supports the charging mode to determine whether it has entered the fast charge\/super fast charge mode.
< br >
Please make sure that your phone model has the fast charge function and the charger you are using supports fast charge. If you cannot confirm, contact Huawei customer service.

Ordinary charging: The icon is single lightning, and the maximum output parameters of the standard charger are 5V\/1A and 5V\/2A.
< br >
Fast charging: The icon is a large and small double lightning, and the maximum output parameters of the standard charger are 9V\/2A and 10V\/2A.
< br >
Super Fast charge: The icon is dual lightning, and the maximum output parameters of the standard charger are 10V\/2.25A, 5V\/4.5A or 4.5V\/5A, 10V\/4A, 5V\/8A, 20V\/3.25A, 11V\/6A.

The earliest lithium batteries are conventional charging, that is, matching voltage charging, and then there are batteries and chargers with fast charging function, the obvious feature is that the charger can be matched according to the fast charging protocol of the electrical appliance, while output normal voltage, it can also change the output 9v, 12v voltage, and improve the charging speed.
