Apple watch battery draining very fast after latest software update

After the latest update my Apple Watch has been draining extremely fast. Prior to the update it was able to last a full day with screen display on all day. Now after the latest update, even switching display to off and only on when raise wrist, as well as not having background apps refresh, the battery barely lasts a half day. Extremely frustrating. I am really disappointed. Hope this problem solved in next update.
