How To Save Battery On Galaxy S8/S8+ Plus With Eye Tracking Feature

If, a couple of years ago, someone would have told you that, one day, your smartphone will be looking at you through its front camera and assess if you’re looking back at it or not, maybe you would have thought that person crazy. Well, a Samsung Galaxy S8 or a Galaxy S8+ Plus can nowadays do such things that were almost incredible not too long ago.

The dazzling function is called Eye Tracking. As you can imagine, it is one of the features that brought these smartphones the title of the best model of the year 2017. Its role is simple and plain: determine if you’re looking away from the display and dim the light, or if you’re looking at the display, and illuminate it. That’s how it helps you save battery and enjoy an awesome user experience at the same time.

When the function is active, an eye tracking icon will show up on the status bar from the top of the display. You’ll see it shows up and then disappears at regular intervals. When it is visible, it keeps scanning for your look.

Scanning for your look means that the front camera of your Samsung Galaxy S8 or Galaxy S8+ Plus runs its eye recognition algorithm. With the help of the front sensors of the camera, the device can recognize if you’re looking at it or if you’re looking away. The judgment is triggered after analyzing simple patterns.

If the app decides that you are, indeed, looking at the screen, it will increase the luminosity of the display, allowing you to see much clear. This is particularly useful when you’re spending time reading things on your smartphone and taking frequent breaks for writing down hand notes or alternating this activity with something else.

Now that we have introduced you to the essentials of how to save battery and improve the experience on Galaxy S8/S8+ Plus with the Eye Tracking feature – also known as Smart Stay – we’d better move on to showing you how to actually activate and deactivate it:

  1. Swipe down the general Menu of your smartphone;
  2. Go to Settings;
  3. Tap on Display;
  4. Search for the Stay Smart option;
  5. Tap on it and check the box next to it;
  6. Look for the eye icon that should immediately show up in the status bar.


Turning eye recognition On and Off only takes checking or unchecking a box.
