Battery Low [Q] Gear 2 Notification Leaving S4 Screen On

Just had a quick question. I have not seen this issue posted anywhere else yet, I can't be the only one. If I receive a text message on my Galaxy S4, and view the notification from my Gear 2, sometimes the S4's screen will not turn off by itself, causing serious battery drain! I have the S4 screen time out set to 15 seconds. This same issue use to happen when I used the Sony SmartWatch 2. Again, this does not happen every time. It is very annoying and kills my battery. Any suggestions?
