Is this not a decline in performance? I have the Watch 8 and I'm pretty sure it lasts slightly over 24 hours. 18 hours means that if you put it on the charger daily for 1 hour then you have to shift the time at which you charge it 5 hours earlier every day.
Even if it was just 24 hours that's not good enough. Let's say you religiuosly charge it immediately after arriving home from work, at 6PM. Then one day you go out to dinner and grab some drinks and stay out until 11. It'll have been 28 hours since you grabbed it off the charger the previous day so you won't have use of your watch that evening.
