Bought my Apple Watch in July 2015 and have used it daily since then including an hour of exercise daily. Don't use apps much but do read news notifications all day long. This month my battery has started to deplete before day's end. I typically go from 0700 to 2400 with watch on and then recharge over night. I used to have 20% or more battery at bed time, but now I am usually at less than 5%. I suspect this is normal wear since my cycle count would be over 700 by now. I would check with Apple but my Apple care expired last month. Should I think about buying a new battery soon or just wait for the new watches to come out?
