hi guys, I got a series 2 Apple Watch and the battery has been excellent. After about 2 hours it would still be at 100% and at times with a 30 min workout, I'd still have 64% after wearing it from 730am to 9pm. However, today it seems to be draining a lot quicker. Still fine - I will last till the end of the day but it's not as great. For example normally it would be around 90 and it's at 76% by 115pm. The only thing I've installed is Dark Sky but have uninstalled now and the battery is still going quicker. Is there a way to check what's using the watch battery the way you can with the phone? What do you think may be causing this? (A week after wearing it). Thanks!
