My charging port, not charging

@saviterah you are not giving us enough information. You need to consider letting us know if anything happened to your phone. It is important to know if it just stop charging and what have you checked and tried to fix it.

First you want to check your charger. Make sure it has the proper voltages. Check to make sure connectors are not bend etc. After that, check the charging port. Clean it of any debris etc, use a few puffs of air to clean it out. Make sure there is no corrosion, debris etc. that prevents it from working. If none of this works, get a ammeter and see if your phone draws any amperage from the charger.

You may also have to consider replacing the battery. A depleted battery can no longer be charged. Measure the voltage on your battery connector with the charger plugged in. You should get around 4.2V If you don't get that voltage check your flex cable coming from the charging board. Make sure it is seated properly and does not have any tears or other damage on it. Your phone has a separate charging board that could be faulty. Consider replacing that.

To replace the charging board, use something like this guide 华为 Mate 10 Pro 充电口更换 It is identical for your model. Replacement charging boards are readily available at many online places.
