I own a series 4 and series 6 40mm. My 6 has been great throughout the day, battery-wise. As good, or a bit better than the 4 even with Aqua on display. However, my 6 was at 100 percent at about 10:30 and this morning at 8:15 it is at 33 percent. It has done that for two nights now. I have made no big app changes. Any thoughts why it’s good during the day but not at night? I do use AutoSleep. Here is a usage screen shot, though I don’t know if it’s useful.
