Battery on Galaxy Watch Series depleted from 90% to 0% overnight

[dortyboy]

Last night, my Watch Ultra's battery unexpectedly discharged completely. It was approximately 90% charged before I went to bed, but upon waking, it was disconnected and powered off. I was unable to restart it because the battery was completely depleted.

This has not happened before. Has anyone else experienced a similar issue?

It happened only once and you shipped it right off for repairs?  It could have been an isolated event.

Nope. It ended up happening again. I sent it in to Samsung for repairs. They found the issue but deemed it Unrepairable. They issued me a $500 coupon to buy a new Watch.

I had the same experience a few nights ago. It's been fine since.

I thought the same thing until it did it again 3 nights ago. I sent it in for repairs.

My watch did this exact same thing last night.  I charged it before bed and when iI woke up 5 hours later it was completely dead.

There is an issue with the device thats unrepairable. Samsung sent me a $500 one time coupon to buy another Watch ONLY.
