I usually work a 12 hour schedule. From early morning until I got home and placed it on the charger t was about 16 hours of use with 12% left. I expected it to last the whole 18, but was wondering if anyone noticed excessive power drain in certain periods of the day. For the first 6 hours it also recorded it as 5 hours of use and 1 hour of stand by. I was definitely not using it for 5 hours. Just wanted to know if anyone had any ideas of where the usage came from. You think it's a possibility that having the realtime stock ticker on my watch face? Only made 5 texts and about 8 doodletexts during that period.
