Our display brightnеss tеsts rеvеalеd that thе iPhonе 14 Pro Max an’ thе Xiaomi 12S Ultra еxhibitеd thе highеst brightnеss lеvеls among thе four dеvicеs whеn thе always on display was activatеd. Howеvеr and a crucial distinction liеs in how thе scrееn is illuminatеd.

Thе rеason for thе Xiaomi 12S Ultra’s еxcеptionally high maximum an’ avеragе brightnеss in always on modе is its bright symbol display in addition to thе timе. This approach contributеs to highеr powеr consumption compared to othеr dеvicеs.
It’s important to notе that all four smartphonеs in our tеsts utilizеd OLED (Organic Light Emittin’ Diodе) display tеchnology and which is morе еnеrgy еfficiеnt than traditional LCDs. OLED displays consumе powеr only whеn pixеls arе illuminatеd and allowin’ for еfficiеnt powеr managеmеnt by sеlеctivеly lightin’ up spеcific arеas of thе scrееn.
While the iPhone provided a bright average screen brightness, its power consumption was the lowest among the tested devices, indicating effective optimization efforts by Apple’s engineers. The Google and Samsung devices exhibited similar power consumption levels but with a less demanding always-on screen experience, illuminating only small portions of the display and maintaining lower maximum brightness levels.
How to Turn Off Always-On Display on iPhone
For iPhone users, the process of disabling the always-on display feature is straightforward:
- Open the Settings app on your iPhone.
- Tap on “Display & Brightness.“
- Scroll down and toggle off the “Always On” option.
By turning off the always-on display, you may experience improved battery life on your iPhone, especially if you don’t find the feature particularly useful or if you prioritize maximizing your device’s battery longevity.

Room for further optimization
While our tests revealed varying levels of optimization for the always-on display feature across different devices, there is still room for further improvement, particularly in the Android ecosystem. Apple’s late entry into the AOD market allowed its engineers to thoroughly study and optimize the user experience, leveraging the company’s hardware and software integration capabilities.
The performance of the iPhone 14 Pro Max demonstrates that further optimization is possible for Android devices, even those that have offered always-on display functionality for several years. By refining power management techniques, selectively illuminating specific screen areas, and leveraging the latest display technologies, Android manufacturers can potentially improve the battery life impact of AOD while maintaining a compelling user experience.
Maximizing Battery Life with AOD
While the always-on display feature undoubtedly has an impact on battery life, there are several strategies you can employ to mitigate its effects and optimize your smartphone’s battery performance:
- Adjust display brightness: Reducing the screen brightness, especially for the always-on display mode, can significantly reduce power consumption. Most smartphones offer automatic brightness adjustments, but you can also manually adjust the brightness levels to strike a balance between visibility and battery life.
- Enable battery-saving modes: Many smartphones offer built-in battery-saving modes or power-saving features that can help extend battery life. These modes may limit background processes, reduce display brightness, and optimize other settings to conserve power.
- Use dark mode or night mode: Enabling dark mode or night mode on your device can reduce the power consumption of OLED displays, as black pixels consume less energy than brighter ones.
- Manage app usage: Regularly review and close unnecessary apps running in the background, as they can contribute to battery drain even when the screen is off.
- Update software: Device manufacturers often release software updates that include optimizations for battery life and power management. Keeping your smartphone up-to-date can help ensure you benefit from the latest improvements.
By following these tips and being mindful of your device’s usage patterns, you can maximize battery life while still enjoying the convenience of the always-on display feature when needed.
Conclusion:
In conclusion, while the always-on display does indeed have an impact on battery life, the extent of this impact varies across different devices and manufacturers. Our tests revealed that some smartphones, like the iPhone 14 Pro Max, have implemented effective optimizations to minimize the battery drain associated with AOD, while others still have room for improvement.
By understanding the factors that influence battery life, such as display technology, software optimization, and user habits, you can make informed decisions about enabling or disabling the always-on display feature on your device. Additionally, embracing power-saving strategies, such as adjusting display brightness, enabling battery-saving modes, and managing app usage, can help you strike the right balance between convenience and battery longevity.
As the world of mobile technology continues to evolve, we can expect further advancements in display technologies, power management techniques, and software optimizations that will help mitigate the impact of always
FAQ,s:
Does the always-on display save battery?
No, the always-on display feature does not save battery life on smartphones. Testing shows it can drain the battery around 4 times faster when enabled compared to having the display completely off.
Is it OK to leave the always-on display on?
Whether it’s OK to leave the always-on display enabled depends on your priorities it provides convenient glanceable information but reduces battery life. If you need maximum battery endurance, you may want to disable it.
Is always-on display bad for your phone?
Always-on display itself is not inherently bad for your phone, but it will reduce battery life and require more frequent charging. As long as you’re aware of the battery tradeoff, it can be a useful feature.
Does the always-on display drain the battery on an iPhone 15?
While the iPhone 15 hasn’t been released yet, if it includes an always-on display like the iPhone 14 Pro models, testing indicates the feature will likely drain the battery faster when enabled based on its impact on current iPhones.
