Up until the most recent Watch OS upgrade I could make it through like 1.5 days, maybe I should just reset the watch and see if that helps... so annoying that's a "solution" for so many Apple productsMy AW 7 lasted almost 2 days with my usage.
My 13 Pro Max used ~25% of battery per day with my usage normally (about 50% for a travel day).
Now, I'm running an Ultra - which hits 72 hours easily and a 14 Pro Max which has slightly more usage than my 13 Pro Max does.
