How Always On Display works in iPhone 13

We continue to get acquainted and talk about the new Apple products of 2021. The launch of the iPhone 13 and iOS 15 is just around the corner , which means we’ll have tons of exciting new features coming soon. Always On Display in iPhone 13 is one of them. Previously, this feature appeared in the Apple Watch, and, you know, it’s very cool that now it will be added to the iPhone. Let’s hope that insiders are not mistaken and in the new iPhone it will be possible to bring the necessary information to the switched off display so as not to activate the iPhone once again. We will tell you what this function is and how it works.

What is Always On Display

According to our own observations, we take out a smartphone and turn it on dozens of times a day. This not only affects the autonomy of the battery, but also just pushes you. Always On Display simplifies the life of the smartphone owner by adding the necessary information to the home screen. This feature was invented a long time ago – I remember it from the Nokia Lumia 930 smartphone, as well as from the Samsung Galaxy S7 smartphones. Still, whatever you say, the new is the well-forgotten old.

The function has been successfully implemented in the Apple Watch – is it the turn of the iPhone?

Always On Display can show different notifications, battery level, or clock just like the Apple Watch . In addition, depending on the ingenuity of the Apple developers, a convenient display of the player may appear so that you can switch tracks.

How Always On Display works

The function practically does not drain the battery – this is its main advantage. And this is achieved due to certain conditions.

  • The new iPhones will have a Retina display – a real AMOLED. This will use the required number of pixels for the controls, rather than the entire screen.
  • It is worth remembering that pixels tend to fade, so on the locked screen of smartphones the image changes its location. By the way, this function is also found on inexpensive smartphones with IPS screens, but it is easier to implement it on OLED matrices.
  • The system must track the position of the smartphone and the level of lighting using sensors – it turns out that a device in a pocket or backpack will not display anything on the screen. The processor, along with otheriOS innovations, will work as economically as possible. And the battery costs themselves for the operation of Always On Display are extremely low.

Always On Display on Phone

I really liked how this function is implemented on the Apple Watch, a little differently than on smartphones – in the case of smartwatches, the entire screen is constantly highlighted, but in moments of inactivity, the frequency drops to 1 Hz. I hope it will work just as well on iPhone 13. Usually this feature allows you to bring the most necessary widgets and functions to the splash screen. It turns out that, unless absolutely necessary, you will no longer need to take out your smartphone and activate the screen. The innovation will be especially useful for those who constantly swear at the rapidly discharging iPhone battery – if Always On Display on the new iPhone 13 turns out to be convenient, then it will be possible to save a lot of battery power.

The function has successfully proven itself on Android smartphones. Why has Apple waited so long?

The function is convenient in that the screen does not require backlighting – only individual pixels. If you look closely at the Always On Display on other smartphones, you can see them. When the function is turned on, it actively uses various sensors: the light and proximity sensor to turn on / off the display, as well as increase the brightness if, for example, you are in the sun, and decrease it if it is dark outside .

How much energy does Always on Display spend

Don’t worry: Always On Display won’t drain your smartphone

Studies show that a similar function on Android smartphones spends 0.65-0.8%, in extreme cases, no more than 1% of the battery charge per hour. It should be borne in mind that the display, being ” face on the table ” or in your pocket, will be turned off altogether. On the other hand, if you already use the iPhone often (and on average, a person activates the screen 150 times per day), the function will not critically affect the battery consumption . Perhaps it will completely disaccustom you to sit in your smartphone, reading our fascinating Yandex.Zen .

Always On Display is a useful feature that does not significantly affect battery consumption. The batteries of modern smartphones can easily cope with this load. Plus, you can significantly save battery power by accessing the information you need without turning on your smartphone.
