1, please use the standard charger and data cable.
Different brands of chargers have different fast charging principles, and mixed chargers may not be able to realize fast charging function, resulting in slow charging.
2, unable to enter the fast charging mode, resulting in slow charging.
If your mobile phone supports fast charging, but it can't enter fast charging mode normally, it will lead to slow charging speed.
3, charging slowly while using.
Run high-power programs (such as taking photos, videos, games, etc.). ) and charging the mobile phone will easily lead to slow charging. Please try to avoid charging when running high-power programs.
4, using computer USB charging, charging treasure charging slowly.
Computer USB interface has low charging current and slow charging speed. Charging treasure generally only supports ordinary charging mode, and the charging speed is slow. I suggest you buy a charging treasure that supports fast charging mode.
5. High temperature leads to slow charging.
Huawei mobile phone has a unique overheating protection design. When the equipment temperature is high, the charging current will gradually decrease.
In the process of charging, the temperature of the device will rise to a certain extent, especially when the mobile phone is in the bright screen state, at this time, some high-power applications and background programs may run, resulting in a significant increase in the temperature of the device and a slow charging. Especially in summer, it is normal that the ambient temperature is high, the heat dissipation of the equipment is difficult, and the charging speed will be relatively slow.
I suggest you try to charge your mobile phone at room temperature.
When charging, temporarily close the background application, close the device screen, and try not to charge while playing.
6. Low temperature leads to slow charging.
In order to ensure the safe use of the mobile phone battery, according to the physical characteristics of the battery, this product is designed as follows:
When the temperature of the mobile phone is lower than 0℃, the battery cannot be charged.
When the temperature of mobile phone is 0℃~ 10℃, the charging current is limited.
When the temperature of the mobile phone is higher than 10℃, the normal charging rate will be restored.
If the above methods still can't solve your problem, please back up important data (QQ, WeChat and other third-party applications need to be backed up separately), and take the equipment, charger, data cable and purchase voucher to the nearby Huawei customer service center for testing.
