Battery Draining Issue

[bhavesh_sonar81]

Dear Customer Service,

My laptop HP Notebook bw531au was bought on 2 November 2018. Recently I found my laptop battery Draining Fast which seems like unreasonable, Once laptop fully changed when I unplug the charger after 6 to 8 hour my battery capacity from 100% drop to 84% while it was off during that moment.

That was the reason I suspect my battery may have problems, therefore could you please help to advice whether it is a defect battery?

Looking forward to your favorable reply soon.

Thank you.
