My MacBook Air battery has been draining too fast for the past couple days. After I charge the battery completely and then unplug it, my laptop usually shows a 100% charge for at least 30 minutes. For the past few days, however, it's been going from 100% to 99% in about 5 minutes. I just bought this laptop last October, so I would think the battery life should still be intact.
MacBook Air, macOS High Sierra (10.13.3)
1. Reset SMC. Choose the method for “If the battery is non-removable”.

Does this help?
2. Hold the option key down and click menu in the menu bar.
Choose “System Information” from the dropdown
Hardware > Power > Battery Information >Health Information > Condition
Does it say Condition: Normal?

If you are still under warranty I would have Apple fix the issue.
