1, without the use of standard charger and data cable charging slow:
< br >
Products that support super fast charge must use the standard super fast charger and the standard data cable to be able to carry out super fast charge, and the use of other models of chargers and data cables is ordinary charging or can not be charged. If you use non-standard charger data cable, please replace it and try again.
< br >
You can judge the charging status of the phone by the battery icon in the status bar:
< br >
Charge slowly when the charger or data cable is not plugged in or the interface is not clean.
< br >
When charging, the charger, data cable, and mobile phone charging interface are not in contact, which may lead to slow charging, failure to enter the fast charge or failure to charge, please plug and unplug the charger several times.
< br >
Check whether the connectors and jacks are clean. If dust is found, it is recommended to wipe it with alcohol or clean it with a brush. If alcohol wipe, need to wait for alcohol to dry, and then re-charge to confirm.
< br >
2. Slow charging while using.
< br >
The mobile phone is charged while using, and part of the current input by the charger needs to offset the electricity consumed by the mobile phone hardware such as the screen when in use, resulting in a decrease in the current to charge the battery and a slower charging speed.
< br >
On the other hand, using the phone while charging will also cause the temperature of the phone to rise, and the charging speed will be further slowed down due to the thermal protection mechanism of the phone.
< br >
It is recommended that you avoid using your phone while charging, especially for applications with high power consumption, such as playing games and watching videos.
< br >
3, slow or unable to charge at low temperatures.
< br >
When the temperature of the mobile phone is lower than 10 ° C and the mobile phone charges slowly or without charging, please put the mobile phone in a warm environment to restore normal charging.
< br >
Note: Normally, the battery is charged when the screen is off and not in use, and the battery temperature is close to the ambient temperature. If it is charged while using, the battery temperature will be higher than the ambient temperature because of the high power consumption of the mobile phone. Therefore, the temperature of the mobile phone can refer to the ambient temperature of the mobile phone when the screen is turned off (turn off all background operations).
< br >
4. Slow charging when the phone is fast full.
< br >
Usually, the charging speed is relatively fast when the phone power is low, and when the charging reaches more than 80%, the battery power is close to full power at this time. 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.
< br >
During the whole charging process, the output current and voltage of the charger are not fixed, but will be dynamically adjusted with the state of the phone, when the battery is quickly full, the charging speed will be slow, which is a normal phenomenon, please rest assured.
< br >
The ambient temperature is high, and the charging of the mobile phone is slow when it is hot.
< br >
Huawei s mobile phone has a special overheat protection design. When the temperature of the mobile phone is high, the charging current will gradually decrease.
< br >
During the charging process, the temperature of the phone will change to a certain extent, especially when the phone is charging, it also runs some high-power programs, which will make the temperature rise significantly, which will lead to slow charging.
< br >
In summer, the weather is hot, the ambient temperature is high, and the heat dissipation of the mobile phone is difficult, so the charging speed will be relatively slow compared with the winter when the ambient temperature is low, which is a normal phenomenon.
< br >
It is recommended that you charge the phone at room temperature as much as possible, and it is recommended to close the high-power applications running in the background when charging.
< br >
5, the use of mobile power charging slow.
< br >
Check whether the output current of the mobile power supply is the same as that of the charger. If the output current is different, the charging may be slow or unable to be charged.
< br >
It is recommended to charge directly using the standard charger connection.
< br >
6, connect the computer USB charging slow
< br >
Check whether the output current of the mobile power supply is the same as that of the charger. If the output current is different, the charging may be slow or unable to be charged.
< br >
It is recommended to charge directly using the standard charger connection.
< br >
7. Large battery capacity leads to slow charging.
< br >
Restart the mobile phone to check whether it can be charged. If the problem persists, back up the data in advance and go to a nearby Huawei customer service center for maintenance.
1, the use of the old model, does not support fast charging function.
2. The charger used is not the original charger. It is recommended to replace the charger.
3, the mobile phone is seriously hot, need to repair the mobile phone motherboard.
4. Caused by system problems. You only need to restore the phone to factory Settings or processing.
There could be a variety of reasons for the sudden slow charging of Huawei phones.
First of all, there may be problems with the charging line, such as wire aging, port failure, and so on.
Secondly, aging mobile phone batteries and battery failure will also cause the charging speed to slow down. In addition, using the wrong charger or USB cable can also affect the charging speed.
Finally, insufficient memory of the phone, or other operations while charging can also cause the charging speed to slow down. Solutions may include replacing the charging cable or charger, replacing the battery, or trying to clean the phone's memory or pause other operations.
Whether because the mobile phone is too hot, when the mobile phone temperature is high, it will limit the charging current, you can turn off the mobile phone applications such as video, games, etc., or shut down, when the temperature drops, the charging will be restored.
