Does the “always-on display” affect battery life?

The Apple iPhone 14 series launched at the end of last year has a new breakthrough–“always-on display”. While it’s a new technology for Apple devices, it’s actually been developed by Android years ago. But does the always-on display affect battery life? How will it affect battery life?

It is reported that a group of battery experts conducted an investigation on this a few days ago. They used these four mobile phones including Apple iPhone 14 Pro Max, Google Pixel 7 Pro, Samsung Galaxy S22 Ultra (Exynos) and Mi 12S Ultra as a reference to study this issue. The display is a power-hungry part of a smartphone. As a result, most smartphone displays turn off after a relatively short period of inactivity. The “always-on display” allows users to view certain types of information, such as the time, without fully waking up the phone. However, the convenience of the always-on display may come at the cost of battery life.

Will the always-on display affect the battery life of your iPhone?

Based on the investigation, experts observed that even though the iPhone offered an average bright screen, it had the lowest power consumption, suggesting that Apple engineers did a very good job of optimizing efficiency. Google and Samsung show similar power consumption, but the requirements for the always-on experience are much lower: only a small part of the screen is lit, and the maximum brightness is kept at a low level. They both show a similar discharge current to the iPhone, while showing a dimmer screen.

As for the Mi 12S Ultra, an Android device, shows the highest battery consumption when the always-on function is on, and while its average brightness is similar to the iPhone, the battery consumption can be explained by its very bright pixels located on the screen. Its unique hieroglyphs. Its maximum brightness is by far the highest. Considering that Android devices have larger batteries than iPhones, the resulting user experience in terms of autonomy gets very similar.

Apple was late to its peers in offering such a feature, but like nearly everything the company rolls out, its engineers delved into how to optimize the user experience by getting the most out of its hardware and operating system. The always-on experience on Android phones has been around for a while, but it’s not quite the same as the iPhone, offering nearly a similar or worse battery experience. The performance of the iPhone 14 Pro Max shows that Android phones can also be further optimized.
