I get about 2 days from my Ultra 1.

  The battery on the Ultras is about double the regular series watch batteries, so that tracks. My point was that I was going to struggle with having a device that I couldn't rely on to make it through a full day including the evening— having to take it off for a charging session in the afternoon would be too disruptive for the overall package to be worth it to me.

  Sure, but the Ultra is double the price of the normal Apple Watch. ($800)
