Still have my first AW3 LTE, I only used the cell service for a month and it wasn't too useful for me at the time and used a lot of battery. I purchased a couple of used AW6's that I'm still alternating with everyday. The battery life is still pretty incredible for a 3 year old watch. I can go through the whole day and use maybe only 60%.....thinking about the upcoming AW Ultra 2 but I really like a smaller size/weight so not really sold on the Ultra. It really doesn't do much more than my 6.
