Suddenly drop one day to 1% on charger / Low watt charging on usb-c

Hi guys, so my problem starts one day I was doing some photo work (Lr, Ps) I was on charger and my percentage dropped to 1% and from that point I got low watt charging (see the screenshot) I'm really upset and I looked at some sites about this model and it was saying that these models had this problem so I typed my serial number on support page and it seems like my device does not have the defective battery also Battery status is showing “good” . Thanks for all answers :)

Keep an eye on your battery! You are already over half its cycles count. You may need to modify your usage a bit. Try not to let the battery drop below 30% so you don't burn a cycle. The more you use your system on the cord the better! Otherwise expect to replace the battery sooner.

I think your just running into a design limitation in this series (2016 onward have this failing)

Unlike the older Retina and Unibody models this series CPU’s & GPU’s can pull more power than the charger can supply! So your batteries power is also drawn and you are running your system hard your system can run into a low power event! As there will be a point the battery can’t back fill the needed power the charger is unable to supply.

I’ve see people who are doing video rendering on these system encounter this power short fall to the point they just can’t get the job done! The best they can do is make sure they have the systems battery fully charged using one port on one side for the charger and then using the other side with an external USB-C battery pack (as large as they can get) and the external SSD RAID drive they are working from. As the vid takes hours to render they setup the system inside a refrigerator! So the system is running as cool as they can get it (to get the most processing out of the system they can) and let it rip!

If the battery is listed in “good condition”, see if exchanging the charging cord for a new one doesn’t help it charge faster.
