My Macbook Air Battery Is not Charging and the Icon Shows Charging
First of all imo you should not provide hardware data of yr computer in plain site (and don’t get me wrong to say this). Its 101 infosec. 
So ...i would try this: 
1. backup my  (time machine &amp; an external HD) -have all my accounts written down (iCloud-appleid- Gmail ets) just in case...
2. Delete all of it  . Restore it from backup.

So it’s:
        Step 1: Back up your Mac
        Step 2: Sign out of everything
        Step 3: Reformat your hard drive
        Reinstall a clean Mac operating system

Now if issue persists , I would take it to Genius Bar .
Hope to have helped you.
