MacBook turns on with Charger only but stays on if unplugged

So I have an Early 2015 13” MacBook Air.

I had to unplug the battery and plug in the charger to get it to boot. Prior to this, the MagSafe charger would show the Amber light and change to Green when pressing the power button before reverting back to Amber a few seconds after.

Now after I got it booted, I shut it down, plugged the battery back in and booted it back up with the charger plugged in. Now the system says the battery is 90%+ charged.

I unplug the charger and the system stays on. I try shutting it off and booting from the battery and it doesn’t work. The battery health status is normal and only 400 cycles.

Any ideas as to what is going on and how I can fix it?

Thanks in advance!

Let’s look at it with a better tool. Download, install and run Coconut Battery, then post your results both with the mag-safe plugged in and with it removed.

I see the battery is still discharging with the mag-safe plugged in, that's not right. Will need to sleep on this one.

Ok. I let the computer drain itself lastnight while I was sleeping but watching the battery go down while I was up seemed normal (not draining quicker than normal)

Also, I know it shows the battery discharging however I have had the laptop plugged in and the battery go from ~80% to 100%
