MacBook pro turns off when unplugged

I have found the solution to this problem and it’s quite easy. This fix is for MacBooks pro 2016 and later. Firstly check and make sure that the battery health is normal, not service recommended. If the battery health is normal then your battery doesn’t have any issue. It’s a software problem. Simply turn off your pc, leave for 1 minute then turn it back on I’m recovery mode (press command + R after pressing the power on button). Make sure your charger is plugged in. After opening recovery mode and choosing the language, proceed to disconnect your charger. Your pc will warn you that the battery is very low. Ignore it. It is a software error. Connect the pc to a wifi and open safari. Browse as much as u can until the battery completely drains out and the pc shuts down by itself (to know if the pc is fully drained after it goes off, try putting it on, if the low battery signal comes on, then the battery isn’t fully drained). After draining the battery, allow for 20 minutes then connect the charger and put it back on, the battery will now charge normally.
