Since Apple’s iPhone 14 Pro landed with the company’s first-ever always-on display, a lingering question has been how much battery the feature drains. In a detailed new test, PhoneBuff has compared how much the iPhone always-on display drains battery with and without a background compared to turning the feature completely off.
Apple originally launched its take on the always-on display for iPhone 14 Pro with colored backgrounds showing up which felt it’s a bit much for some people.
With iOS 16.2, Apple pleased those looking for customization as you can opt to disable the wallpaper and notifications for the always-on display. That results in a more subtle – and Android-like – always-on experience.
iPhone 14 Pro always-on battery drain results
As it turns out, after 24 hours of testing, the iPhone 14 Pro always-on really doesn’t use much battery.
- Always-on with wallpaper = 0.8% more battery drain per hour
- Always-on without wallpaper = 0.6% more battery drain per hour
An important detail to remember is that would only be the case if always-on was truly always on, which it isn’t. Your screen goes still goes fully dark when:
- Your iPhone is lying face down
- Your iPhone is in your pocket or bag
- Sleep Focus is on
- Low Power Mode is on
- Your iPhone is connected to CarPlay
- You’re using Continuity Camera
- You haven’t used your iPhone for a while (your iPhone learns your activity patterns and turns the display off and on accordingly, including if you set up an alarm or sleep schedule)
- Your iPhone detects that you moved away from it with a paired Apple Watch (Always-On display will turn on when your Apple Watch is close to your iPhone again)
But in the worst-case scenario, always-on could use up 20% battery in 24 hours if it was on the whole time.
Another interesting comparison was the iPhone 14 Pro vs the Galaxy S22 Ultra for always-on drain and they both ended the 24-hour test with 84% charge after starting with 100%. Check out PhoneBuff’s full video for all the details:
