Dark mode in Microsoft 365

Spending many hours staring at a screen with white light causes eyestrain. Decreasing visual fatigue and reducing battery usage are some of the benefits that Dark Mode in Microsoft 365 offers us in services and applications. According to a study by XDA Developers, when using Dark Mode, it is possible to reduce up to 63% battery consumption. 

The dark theme changes the default bright background color in Microsoft 365 to a darker color, this theme helps protect the eyes in low light environments or if the user prefers to work on less bright interfaces. 

Whether you want to reduce eyestrain, improve battery life, or it just has aesthetic appeal, Dark Mode gives us the ability to create simple and flexible Microsoft 365 experiences.
