Apple Watch draining quickly for no reason

I wear my watch almost all the time, charging it to full before bed so I can track my sleep. Usually in the morning the percentage is roughly 92%. The day before I did the 17.5 update the draining started. Despite the update, as of 10 am, it’s 73%.

I haven’t changed any settings, I haven’t changed my routine, and I am at a loss.

I see many other people with the same issue while Apple is claiming there isn’t a problem.

I’m frustrated!
