Ever wondered if switching to dark mode could save your phone’s battery life? The answer might surprise you! While dark mode does save battery, how much it helps depends on your screen type and brightness settings. Let’s dive into the details.

How Does Dark Mode Save Battery?
The amount of power saved depends largely on your display type:
Display types Explained
- LCD (Liquid Crystal Display) Screens – LCD screens use a constant backlight, meaning dark mode doesn’t significantly reduce battery life.
- OLED (Organic Light-Emitting Diode) Screens – Each pixel generates its own light, so a dark background turns off pixels, saving significant battery power.
OLED vs. LCD: Battery Savings Explained
According to research from Purdue University, switching from light mode to dark mode at 100% brightness results in battery power savings of 39%–47% on OLED screens. Similarly, PhoneBuff’s test revealed that using dark mode could extend an iPhone’s battery life by 30%.
Other Benefits of Dark Mode
Beyond battery savings, dark mode also: ✅ Reduces eye strain, especially in low-light conditions ✅ Minimizes blue light exposure, which can improve sleep quality ✅ Enhances aesthetics, giving a sleek, modern look to your apps and interface
Should You Use Dark Mode?
If your device has an OLED screen, dark mode can significantly boost battery life—especially at high brightness levels. For LCD screens, the savings are minimal, but dark mode can still be useful for comfort and style
