Placing an iPhone face down prevents the screen from lighting up with notifications, which can significantly prolong battery life. This feature, known as Facedown Detection, utilizes ambient light and proximity sensors to keep the screen off. Many users receive a high volume of notifications daily, leading to substantial battery drain. Without any method from Apple to stop the screen from waking, the primary way for users to save battery is by placing the phone face down. Limiting push notifications is another option to reduce battery consumption.
Placing your iPhone face down on a surface prevents the screen from lighting up every time you get a notification.
This feature, called Facedown Detection, uses ambient light and proximity sensor to make the screen go black based on surrounding light levels.
A 2023 study found that about half of girls aged 11 to 17 receive over 230 notifications a day.
Over time, notifications can mean your phone is on for a much longer period, draining battery life significantly.
