S9 Battery Issue

[assist4tech]

New problem with S9 Battery. After the battery drops to 15%, you get a warning message ". If you do not connect the charger, battery drops to 5% in under 5 mins and phone goes dead.

Any idea what's the issue? 

ACU Battery shows battery life at 83%. So doesn't look like a battery issue.

Any ideas?
