So today was my first day with my Apple Watch. It was charged to 100% and I took it off the charger at 11:00am and went about my day. It's now 8:30pm and my battery is down to 12%. 9 and a half hours to 12%.... This doesn't seem too good, especially considering there wasn't heavy usage. Here is what I used it for today: - Alerts that came up on it: Handful of Gmail / Mail / Facebook / SMS messages. - I also sent about a dozen SMS messages from the watch. - I used GPS on the watch for about 10 mins total (or less) - I ran it all day with the brightness at the lowest setting - Sound was on mute all day - Had one 15 minute walk And now it's almost dead. Please tell me this is some sort of "first charge doesn't last as long but after that it will run much longer" kind of thing or something.... otherwise, having an almost dead watch at 9.5 hrs of use and really not doing that much on it is kind of.... terrible.... Anyone else have similar experiences or recommendations? Reminder: my brightness is all the way down, I'm set to mute and only exercised for 15 mins... I know how to turn off the heart sensor, but I'd rather not start disabling all the features of this thing to get promised battery life.... Thoughts?
