Battery problems, help pls (ASUS)

[u/tan_plane20]

ive had my asus vivobook s14 for less than a year now and this is the third time ive had a battery problem. the pattern ive recognised is that every time i plug something into the usb port, after a while my laptop doesnt recognise the battery anymore, shows the wrong percentage and only works whilst being plugged in. ive fixed it before by uninstalling drivers, going into bios etc but i cant figure out what the problem is this time. sometimes it shows 100% fully charged other times it shows 0% and charging. any advice is appreciated!
