The behavior that you described generally means that something is wrong either with the battery charging circuit or with the battery itself. Most often it is the battery.

When you plug your 2015 MacBook Air to electrical power then what does the battery charge level state? Note that, at times, the charge level does not matter because if the battery health is bad then it can discharge very quickly.

My recommendation is to have your MacBook Air examined at the Apple Store or at an Apple Authorized Service Center.
