Charge 3 won't hold a charge

[SophieG88]

I've started having a recurring problem with my Charge 3 during the last 24 hours.

Out of the blue, it started vibrating constantly, screen blank, button not working. The only way to fix this was to plug it into the charger and force a reset. At that point, it showed the battery as being very low, when previously it had been fully charged.

I let it charge fully, then did another reset for good measure, and unplugged. An hour later, it did it again - vibrating constantly, screen blank etc. Plugged it in to the charger again, reset again... and apparently the battery is depleted.

So I let it charge fully AGAIN, put it on, went about my business... and now (less than half an hour) it's just given me a 'low battery' notification. Surprise surprise, the battery was at 8%. I've just gone to check it again and... boom, it's dead. Screen blank, button not working. It's also very hot.

I've had this model for 18 months now - guessing I'm going to have no luck with the warranty?
