High-def is good enough
Out of the box, the Galaxy S8’s screen resolution is set to full high-definition. By using a lower resolution, battery life improves, and everyone wins. Well, except those who want to use every single pixel on the S8’s screen.
Though let’s be honest, you don’t truly need the super high-res WQHD+ display when sending WhatsApp messages. It makes sense, however, to watch videos and play games with the full capabilities of Samsung’s display. So, compromise.
For everyday use, leave the S8’s display set to FHD. Then you can save up high-performance mode for when you’re playing games or binge-watching “13 Reasons Why.” There’s a dedicated tile to boost your device’s performance in the settings shade.
You can then go back to a less battery hungry mode at any time by using the same method to turn off high-performance mode.
