Starbucks app doesn't turn off screen

[SunsetRunner]

Here is a tip I learned the hard way. I use the Starbucks app on my Versa. It works fine and I appreciate that the display doesn't turn off after just a few seconds because we all know Starbucks lines don't move rapidly at times and it is annoying to keep waking the phone screen, for example. The problem is that the Starbucks app won't turn off the display at all. The other day I used it while wearing a long sleeve shirt and sport coat. Then I went about my business. Many hours later I received an email that my Versa battery was low. I had just charged it that morning. When I then looked at the Versa for the first time since ordering my coffee, I noticed the Starbucks app was still displayed on the screen. It apparently had kept the screen on all that time. It isn't a burden to manually turn the screen off after using the app, it was just an unexpected behavior that I thought I would share.

Thanks for the tip, @SunsetRunner. I’ve found the same to be true for several of the apps. I’ve gotten in the habit of pressing the button on the left to return to the clock face after using any app. It’s second nature to me now. 

Hey, Welcome to the forums!

Hey there @SunsetRunner, thanks for stopping by and sharing your experience! I agree with @SunsetRunner, this has happened to me with my Ionic and my Blaze. I blame myself because I forget to press the button to go back to the home-screen. 

As you may know, the Fitbit Versa battery can last up to 4+ days. Because battery life is affected by use and other settings, actual results may vary.

Consider these tips when you want to conserve battery life:

• Make sure you're charging Versa fully each time. It can take up to 2 hours to charge your watch. 
• Turn off All-Day Sync in the Fitbit app because it increases battery drain on both your watch and phone. Note that if you turn off All-Day Sync, certain apps including Weather won't work since data isn't being sent from the Fitbit app to your watch:
  
  1. From the Fitbit app dashboard, tap or click the Account icon > your device image.
  2. Find the option to turn off All-Day Sync.
• Turn off the option to wake the screen when you turn your wrist; instead, tap the screen to turn it on:
  • On your watch, press and hold the back button, then swipe to the quick settings screen > Screen Wake > Manual.
• If you don't need heart rate data, change the Heart Rate setting to Off. Note that the green LED continues to flash even if Heart Rate is turned off.
• Turn off call, text, calendar, and app notifications if you know you're going to receive many hundreds of notifications. A large volume reduces battery life:
  • On your watch, press and hold the back button, then swipe to the quick settings screen > Notifications > Off.
• Charge your watch more often if:
  • You play music or use the music controls frequently
  • You use apps that keep the watch's screen on or frequently access the internet
  • You use an interactive or animated clock face
• Don't receive reminders to move every hour. To get fewer reminders, make sure you walk 250 steps each hour, change the number of hours you want your stationary time monitored, or turn off the feature on days you don't need it.
• If you have many silent alarms set, consider deleting some. Each alarm you add up to the maximum of 8 reduces battery life by a small percentage. 
• Shut down Versa when it's not in use. 

PS:  I moved your post to the Versa board as there are more chances to get related replies here, your post is more related to the Versa itself than the App Gallery. 

Hope this helps, let us know if you need further assistance!
