Dell XPS only charges up to 99 percent!!

I recently bought a Dell XPS 15 9570. One of the things I've noticed is that when I charge it, it goes up to 99% - charging, and never gets to 100%. It never says fully charged, and flips between saying 99% charging, or 01 minute to full charge. I've waited 40 minutes on 99% charge and it still never gets to 100.

Is this supposed to happen? While there are no other issues with the laptop and I am fine with the 99% charge, I'm concerned that this issue may escalate into a bigger battery problem that I would rather deal with sooner than later.

Thank you in advance
