iPhone 14 Pro Max Always On Display Battery Test

Hey there! Have you ever wondered how much the Always On Display feature drains the battery on the iPhone 14 Pro Max? Well, PhoneBuff has got you covered with their latest video. In this test, they compared the battery drain of the iPhone’s Always On Display with the Galaxy S22 Ultra’s AOD. They made sure to provide some important test notes, such as factory resetting all phones, enabling airplane mode, and calibrating the screens to 200 nits with auto-brightness turned off. They also had their trusty robots wake the screens every hour to prevent the AOD from turning off due to inactivity. So, if you’re curious to find out how the iPhone 14 Pro Max performs, grab some popcorn and join them on this battery-draining adventure!

Apple has finally introduced the Always On Display feature to the iPhone with the 14 Pro and the 14 Pro Max. However, Apple being Apple, they did it in their own unique way with not just widgets and notifications on the screen, but also a full wallpaper. While having the wallpaper on might drain the battery more compared to a black background on Android phones, Apple’s optimization skills might just save the day. The 14 Pro’s new display can ramp itself all the way down to one hertz, making it more efficient than its predecessors and even the Galaxy’s minimum 10 hertz. Today, PhoneBuff is not only testing the always-on display on and off, but also trying out iOS 16.2’s new option to disable the wallpaper. And if that’s not enough, they’ll later be comparing the results to the Android counterpart, the Galaxy S22 Ultra. So, sit back, relax, and get ready to dive into this fascinating battery test!

Understanding Always-On Display

Definition of Always-On Display

Always-On Display is a feature available on smartphones that allows the screen to remain partially active even when the device is in standby mode or locked. It displays information such as time, date, and notifications without fully lighting up the screen or requiring the user to unlock the device. This feature provides convenience and quick access to important information without having to constantly wake up the phone.

Its function on smartphones

The main function of Always-On Display is to provide users with at-a-glance information without the need to unlock their smartphones. It enables users to easily check the time, date, and notifications without fully powering on the device, saving both time and battery power. Always-On Display also enhances the overall user experience by providing a sleek and futuristic aesthetic to the device.

Comparison between iOS and Android platforms

Both iOS and Android platforms offer the Always-On Display feature, but there are some notable differences between the two. In terms of customization options, Android allows for more flexibility, with users being able to choose from a variety of clock styles, designs, and even add widgets to the Always-On Display screen. On the other hand, iOS provides a more streamlined and minimalistic approach, with limited customization options but a sleek and seamless display.

The Context of the Test

The iPhone 14 Pro Max settings prior to testing

Before conducting the battery test for Always-On Display on the iPhone 14 Pro Max, all phones were factory reset to ensure a fair and unbiased comparison. No additional apps or iCloud sign-ins were present on the devices. The test was conducted with Airplane mode enabled on all phones to eliminate any external factors that could affect the results.

The reason for factory testing the iPhone

Factory testing the iPhone was necessary to accurately measure the impact of Always-On Display on battery life. By removing any additional factors that could consume battery power, such as third-party apps or background processes, the test focused solely on the performance and efficiency of the Always-On Display feature.

How settings were optimized for testing

To ensure consistent and reliable results, the screens of all phones involved in the test were calibrated to 200 nits with auto-brightness turned off. Although the Always-On Display adjusts its own brightness, turning off auto-brightness helped create a controlled environment for testing. Additionally, the lab lighting was calibrated to either 150 or 1000 LUX to simulate different lighting conditions typically encountered by users.

The Testing Scenario

How light intensity was measured and factored into the test

Light intensity plays a crucial role in how the Always-On Display performs in regards to battery consumption. By calibrating the lab lighting to different LUX levels, the test aimed to replicate real-life scenarios where the screen brightness would automatically adjust to ambient lighting conditions. This provided a more accurate representation of how the Always-On Display functions in various environments.

How factory settings were used as a baseline for comparison

Using factory settings as a baseline helped establish a standard for performance comparison. By measuring the battery drain of the device with the Always-On Display enabled, as well as with the display completely off, it was possible to determine the impact of the feature on overall battery longevity.

The use of robots to simulate user activities

To prevent the Always-On Display from turning itself off due to inactivity, robots were programmed to wake the screens every hour on each phone. This ensured that the test accurately represented the real usage patterns of users and prevented any interference from the device’s power-saving mechanisms.

Reason behind the choice of Galaxy S22 Ultra for comparison

The Galaxy S22 Ultra was chosen as a comparison device for the battery test due to its popularity and similar feature set. By comparing the battery performance of the iPhone 14 Pro Max’s Always-On Display with that of the Galaxy S22 Ultra’s AOD, it allowed for a comprehensive analysis of how the two flagship devices stack up against each other.
