A couple of days ago I noticed that my watch's battery life has fallen off a cliff. Before almost every day I would put it on the charger with 25 percent or more battery left. Now for the past couple of days it has gotten below 10 percent in the same usage time. I didn't notice any change in the first iOS 9 beta release, but I upgraded to the second one recently and it has all happened since that. I even turned off Hey Siri to conserve battery, which isn't a big deal since I was annoyed with having to say "Hey Siri" twice to get it to work. But it still seems to have a couple hours less battery life. Anybody else noticed this recently? I've been going the same places and doing the same things, so it's not like I all of a sudden started running three miles a day and it's using the heart rate monitor much more.
