Why is iPhone 15 always-on?

The iPhone 15 Pro and iPhone 15 Pro Max include the Always-On display feature. This cutting-edge technology not only dims the Lock Screen but also provides valuable information such as the time, widgets, and wallpaper.

Thanks to revolutionary advancements in power efficiency, the display remains highly efficient, ensuring minimal  battery usage when this feature is used.

However this feature has an impact on how you power off your iPhone 15.

How do I turn off the Always-On display?

If you want to turn off the Always-On display, do the following:

Why does my iPhone 15 Pro and Pro Max not turn off?

The Always-On display is on by default on iPhone 15 Pro and iPhone 15 Pro Max so the display will not go completely black like other iPhone models.

Does the iPhone 15 turn off automatically?

The iPhone 15 does not switch off automatically. Unlike traditional screens, the display never turns off or goes completely black, even when the lock/power button is pressed. Instead, the Always-On display feature gracefully transitions into a dimmed state, ensuring vital information is visible on-screen at a glance all the time.

Why does my iPhone 15 not go to sleep?

If you have the Always-On display enabled on  your iPhone 15 Pro or iPhone 15 Pro Max, the display will not dim giving the impression it is not asleep. However, this is not true and your device will be using very little power.

According to test done by MacRumours, battery drain with Always-On enabled is only 0.8% per hour. If this is too m uch for you, you can always disable this feature.

If you have another model of iPhone 15 that won’t go to sleep, you can force restart it.

  1. Fixing problems
    Sometimes, the iPhone may have little problems with its software. Turning it off and on again can help solve those problems and make your phone work better.
  2. Saving battery
    When your iPhone is turned off, it’s not using any power. This means the battery can last longer. It’s like giving your phone a rest so it can have more energy later.
  3. Updates and improvements
    Turning off your iPhone helps it update and get better. Updates bring new features, fix bugs, and make your phone safer. When you turn it back on, it can install these updates smoothly.
  4. Following rules
    In certain places like airplanes or places where wireless signals can interfere with important equipment, it’s important to turn off your phone to follow the rules and make sure everyone stays safe.
