Initially, the always-on display debuted with the iPhone 14 Pro. One might think that any models released after the iPhone 14 Pro might have an always-on display feature by default. Well, if you feel the same way, you're not entirely wrong. Always on display is only available in the Pro and Pro Max versions of the iPhone 15 and 16 series. The standard iPhone 15, 15 Plus, 16, and 16 Plus do not have always-on displays.

The older versions, including iPhone 13 and earlier, also don't have AOD; instead, they have a standby mode that transforms your device into a smart display when it's charging and is placed horizontally.

What does always on display mean?

Always on display is a feature in newer iPhones that keeps the screen lit with a dim light when the device is locked or in standby mode.

This feature offers users convenience by making essential information visible without requiring them to unlock their device every time. This information includes time, date, weather, and notifications, among other things. The information displayed is customizable, allowing users to choose the display information according to their needs and even create custom themes.

Does the always-on display in iPhones drain battery?

While the always-on display feature on iPhones is designed to be energy-efficient, it does drain the battery. The feature uses some power to keep the display active, leading to a noticeable reduction in battery life.

However, the amount of battery that gets drained depends on several factors, including display brightness, the type of information being displayed, and whether a wallpaper is set.

Apple has introduced several measures to optimize battery usage when the always-on display is enabled. This includes turning off the display when the phone is in the user's pocket, facing down, and when an Apple Watch is also in use.

How to turn off the always-on display?

The always-on display on iOS automatically turns off after a certain time to conserve battery. However, if you feel that this feature isn't for you and you don't find it helpful, you can always turn off Always On Display permanently.
