Sorry, forgot to specify. It is a 44mm SBTi. I can’t believe it myself either, especially after owning the S5 44mm with atrocious battery life. My S4 44mm was somewhere in between these two. Yes, I have everything turned on (AOD included). One thing of note, I haven’t been really exercising in the last few months (winter hibernation) so that may attribute to the excellent battery life. But I do get an insane amount of Security camera notifications through the night on the watch. It fluctuates tho per hour. The highest per hour battery drain I’ve seen so far is 2.8% since I been paying attention but that with heavy usage.
