The Huawei Mate7 suddenly charges very slowly

There may be the following reasons for slow phone charging:

1. The ambient temperature is high, and the charging is slow when the mobile phone is hot

Huawei mobile phones have a special overheat protection design, and when the temperature of the mobile phone is high, the charging current will gradually decrease.

During the charging process, the temperature of the mobile phone will change to a certain extent, especially when the mobile phone also runs some high-power consumption programs, which will make the temperature rise significantly, which will lead to slow charging.

In summer, the weather is hot, the ambient temperature is high, and the mobile phone is difficult to dissipate heat, so compared to the winter when the ambient temperature is low, the charging speed will be relatively slow, which is a normal phenomenon.

It is recommended that you charge your phone at room temperature as much as possible, and it is recommended to close high-power apps running in the background when charging.

2. Charging slowly while using it:

When the phone is charged while it is in use, part of the current input by the charger needs to offset the power consumed by the mobile phone hardware such as the screen when it is in use, resulting in a decrease in the current used to charge the battery and a slower charging speed.

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 slower due to the thermal protection mechanism of the phone.

3. Slow charging when the charger or data cable is not plugged in or the interface is not clean

When charging, the charger, data cable, and mobile phone charging interface are not in good contact, which may lead to slow charging, inability to enter fast charging or failure to charge, please plug and unplug the charger several times.

Please check that the connectors and jacks are clean, and if you find dust, it is recommended to wipe them with alcohol or clean them with a brush. If it is an alcohol wipe, wait for the alcohol to dry before recharging for confirmation.

If the above problems cannot be resolved, we recommend that you back up your data and bring the invoice to the Huawei after-sales service center for testing and processing.

Slow charging is not caused by a malfunction, but by the heating of the phone.

Confirm whether the phone is too hot: Huawei's unique thermal protection optimization design, when the temperature of the phone is high, considering the user's hand comfort, it will limit the charging current, you can turn off the phone's applications such as **, games, etc., or turn it off, when the temperature drops, the charging will resume again. Please see if the charging plate is good or whether the charger is plugged in place; It is recommended that you turn off the apps of your mobile phone such as **, games, etc. when charging, so as to speed up the charging time and reduce the temperature of the mobile phone.

Hello, please see if the charging plug board is good or whether the charger is plugged in place; Confirm whether the phone is too hot: Huawei's unique thermal protection optimization design, when the temperature of the phone is high, considering the user's hand comfort, it will limit the charging current, you can turn off the phone's applications such as **, games, etc., or turn it off, when the temperature drops, the charging will resume again.

Huawei Mate8 uses a lithium battery, there is no memory effect, and the first charge only needs to be fully charged normally. Maintenance of mobile phone battery: When charging the battery, you should use the original charger of the original factory, and try not to use the universal charger.

Otherwise, it may damage the battery cell and reduce the service life. When using a phone, sometimes you wait until the battery runs out.

Are you using an original charger? Other chargers charge slowly.
