The concept of a dark theme to reduce glare isn’t new, but for some reason, it has started to gain a lot of traction in the mobile scene in recent years. There are a couple of reasons for this, one of which is health reasons where too much glare is bad for our eyes, especially in a low-light setting.
Another reason is for battery purposes, where OLED displays can actually benefit from dark mode which could save battery on your phone. This is due to how OLEDs work, where each pixel has its own light, so in dark mode, which is usually black, it basically turns the light off. Less lights used equates to less energy used, which ultimately can help save battery.
When Apple introduced iOS 13, one of the new features is a system-wide dark mode, and if you’d like to learn how to turn on the feature, here’s how you do it.
If you prefer using Light Mode during the day, and Dark Mode at night, then obviously having to constantly switch back and forth manually can be tedious. However, the good news is that similar to Night Shift mode, Apple has included an automatic Dark Mode. This is based on a schedule that you set or based on sunrise and sunset, where iOS will automatically switch between either mode.
