Get Better Battery Life
When it comes to power-saving colors on an OLED display, the first thing that comes to mind may be black. But there are actually other more energy-efficient color options you can consider if you want to get the most battery life out of your Apple Watch.
For example, using greens and yellows can save a significant amount of battery compared to whites, blues or purples on OLED displays. How can you apply this in practice? Just take it into account if you use a watch face that allows for color customization.
