My Apple watch was fully charged and working. See it is at 94% on my iphone when I get warning that power is low (under 10%). This happens frequently. I go through the "power down/ power up " sequence on both devices- even rebooting. Power level then returns to high 90's only to have same warning return 1 hour later. Any ideas?

To understand Apple Watch performance and its relation to your battery, see:
Apple Watch Battery and Performance - Apple Support
“Battery life” is the amount of time your device runs before it needs to be recharged. “Battery lifespan” is the amount of time your battery lasts until it needs to be replaced. Maximize both and you’ll get the most out of your Apple devices, no matter which ones you own. See the "Tips for Apple Watch" section in:
Batteries - Maximizing Performance - Apple
If the battery drains too fast after an update, see the replies to:
