Twitter's night mode is a feature that allows users to switch to a darker color scheme for their Twitter interface. This can be helpful for those who use Twitter in low-light environments, as it reduces the amount of strain on the eyes. Additionally, it can also help to reduce battery consumption on mobile devices, as the darker color scheme requires less power to display. Knowing how to use Twitter's night mode can help users to get the most out of their Twitter experience.
