Nowadays, mobile phones are more than just phones - as with any kind of device, it facilitates our daily tasks. However, the more we are on our phones, the more we drain the phone's battery. On the other hand, Mobile Phones companies try to enhance our phones to prolong the battery. However, is it always the case?, I sometimes ask myself. Take a look at this new mobile phone option ‘’always-on Display’’! Here are some observations on this feature.

What is Always-on Display Feature

‘Always-on’’ feature on mobile phones enables our phones to be in wake-up mode. In other words, our phone displays won’t turn off when we’re not using our phones. For example, when enabling this option, it means this: you’re on your phone, you need to do something, you leave your phone on a table, and upon completing your task, you come back to pick up your phone, your display will be turned on, not off. You don’t need to wake up your phone; unlock it in your preferable way, and you’ll be able to use it instantly. 

Of course, you might turn off this option when in public places or at work, to keep your privacy from curious passers-by. That’s okay. However, another concern is how much it drains our phone battery. Of course, it depends on our phone operating system and its brand. Dxomark did research on this, so let’s see what they found out.

Always-on Feature vs. Battery Life

The Dxomark team did quite thorough research on this. They used four different smartphones for this research, and they are the Xiaomi Ultra 125, Apple iPhone 14 Pro Max, Samsung Galaxy S22 (Exynos), and Google Pixel 7 Pro. The test was under controlled conditions, such as a temperature of around 22°C (71.6°F), phones placed in a Faraday cage, with 50 lux of ambient light, and battery power at different percentages.

Some phone features were on, such as airplane mode,  auto-brightness mode, and adaptive refresh rate, while features such as Bluetooth, data, Wi-Fi, and location services were off. For displaying the measurement, the Dxomark team used a Radiant imaging colorimeter. So, you wonder what the results are.

They found out that the ‘’always-on’’ display feature drains battery life more than expected. In other words, your phone battery will last for 100 hours with this feature turned on, while it could last 400 hours with this feature turned off. It just makes me wonder whether the phone manufacturers did any research before including this feature. This Dxomark team ran some additional tests as well, and they all proved that this feature is better to be turned off.

Always-on Display Failure

Even though phone manufacturers had the best intentions when enhancing our phones’ features and functions, it’d be much better to run thorough tests for some questionable features, such as this one. Everyone needs a phone with a longer-lasting battery since our phones are our precious tools.

    Apple was forced to add USB-C to a phone and the maccultists start talking about “revolution” and “paradigm shift” (as if USB phones had never come out before). It’s so ridiculous it’s reminiscent of comedians doing the “stepped on a water hose” stunt – that was at least somehow funny a hundred years ago.
    Reading this on a site that used to be a technical resource is especially ridiculous.
    How pathetic

    “An iPhone 15 with a USB-C port will mean more than you think”

    That Apple can finally stop hindering progress if spanked hard enough ?

    I’m thrilled to see Instagram taking steps to enhance the user experience with features like Live Activities. This update is a game-changer, especially for those who frequently upload content on the platform.

    The ability to track upload progress in the background is a simple yet incredibly useful addition. It not only keeps users informed about the status of their uploads but also allows for a more seamless experience on the platform. No more constantly checking if your post has successfully uploaded or worrying about interrupted uploads due to a weak signal.

    As an active Instagram user, this feature is a relief. It showcases Instagram’s commitment to improving user satisfaction and addressing common pain points. It’s all about making the platform more user-friendly, and this feature certainly accomplishes that.

    I can’t wait to try out Live Activities and enjoy a stress-free posting experience. Kudos to Instagram for continually innovating and making our social media lives easier!

    Keep up the great work, Instagram, and thanks to ghacks for keeping us in the loop with the latest tech updates!
