Charge 5 suddenly became unstable

[Ronian]

My Charge 5 started behaving weirdly today. Although fully charged, it displayed 20% of battery just one minute after being disconnected from the charger. The screen sometimes does not turn on after tapping. This device is still under 1 year of warranty.

@DavideFitbitThanks for getting back. I tried the suggested steps and the problem persists. Although fully charged, the battery is completely drained within an hour. I think the battery of my device might have failed. As the device is still under 1 year warranty, can you instruct me how to get it replaced?

I've been informed that you already contacted the Customer Support team for further assistance with this and it seems they've provided you with some instructions. In this case, they will let you know how to proceed.
