MacBook Air shows battery as power source when plugged in

MacBook Pro: Battery icon shows as charging even when not connected to power source

My Macbook Pro says I'm connected to a power source even when unplugged

SMC reset didn't work for me, and turning the option off and on again didn't help either.

I am using a 15" 2018 MacBook Pro.

The sensor doesn't seem to be damaged as suggested in one of the answers as I can see some difference in reading when disconnected and connected back to the charger -

Charging: enter image description here

Not charging: enter image description here

How do I fix this issue?

Since the laptop is assuming that it's connected to a power source, I feel that the battery is depleting faster than expected.

Update: I have observed that when I remove the plug it shows me the "charging" status for some time (3-4 minutes) and then switches to "not charging but plugged in" status. Further, I don't get the sound which denotes the charger is plugged in when I plug it.

I had this issue once, SMC reset didn't help neither nor turning the option off and on again...

What I did was:

  • I turned off my MBP without beeing connected to a power source
  • I connected it and waited until the charging logo appear
  • I turned it on still connected

After that, it came back to normal

(I noticed this bug when I was looking at the istat menu battery log while pluggin/unpluggin the power source)

  • How could the "charging logo" appear (2d bullet point) if the MBP is still turned off? – DavidSupportsMonica Feb 21 at 23:24
  • Well, I don't know, but when I plug my MBP when he's off a logo appear shortly after the plugging sound and show the % of battery level – Edd Growl Feb 22 at 7:56
