Check to see if the type C jack is inserted in place, if there is dust or liquid into the usb interface, it will also affect the fast charge. After seeing whether the data cable and plug are damaged, if there is no problem, please restart the device to try, if it can not be solved, please go to the after-sales network for help.
When charging, see if the jack is plugged in tightly, you can clean the dust and foreign matter inside the jack and then charge it. In addition, try not to use the mobile phone when charging, you can clean up the background program before charging.
First see if you are using the original charger and data cable, if not, change to the original\/standard try. When charging, see if the jack is plugged in tightly, you can clean the dust and foreign matter inside the jack and then charge it. In addition, try not to use the mobile phone when charging, you can clean up the background program before charging.
I have also encountered this kind of situation, the beginning has always been super fast charge, there are two night charging did not plug, and charged until the next morning, after which it is automatically identified as ordinary charging, and it is also the same with the original charger, charging speed is very slow. Plug and unplug twice when just charging (unplug the charger from the plugboard, unplug the charging head cable, leave it for a while) and then charge like back to super fast charge.
In addition, when the power is very low, it can withstand a larger charging current (power), and the more full the battery is, the smaller the charging power it can withstand. So going from 0 to 50% is fast, and then it gets slower and slower.
