How to turn ON/OFF auto brightness on iPhone? – iOS 14

Auto brightness, also commonly referred to as adaptive brightness – is a super cool feature in all smartphones lately. The feature aims to sense the amount of available light in the surroundings and adjust your phone’s brightness accordingly to ease the visibility of contents on the phone

For example, if you are out in the sun or in a closed dark room, your eyes need different levels of brightness on it to be able to either see the screen properly or to avoid stress for your eyes.

In the bright sun, the sensor on the top of your iPhone detects ample light and increases the brightness to near maximum. If you are in a dark room, let’s say on your bed at night, all the extra light can strain your eyes and also affect eyesight in prolonged cases, so it decreases the brightness level to the middle or minimum. Why auto brightness is suggested – is because the phone does it by itself, without you having to adjust the settings frequently throughout the day

Why Auto-Brightness is GOOD?

Auto brightness was designed to save the eyes! Another great advantage of having an adaptive brightness setting is that it is designed for people who cannot change the setting manually throughout the day either due to dirty and greasy hands like a physical worker or a chef- you get the idea. But there are moments when they want to quickly look at the time on their phone or a reminder or simply want to pick up a call. In case auto brightness is off, the person will have to manually adjust, which is time consuming on an iPhone unlike in androids.

You can now read at night or scroll through social media without disturbing other people present in the room automatically!

Auto brightness was also made to cut out the battery wastage caused due to keeping the phone on high brightness all the time. The phone could now change the brightness according to the light around it

Why Auto-Brightness is BAD?

The bad side of the auto brightness feature is that it is not accurate enough yet, although it has gotten better over the years through updates and research. The inaccuracy defeats the purpose of the amazing well thought-out feature.

The problem is that it is not particular to the user, that is, it is not customizable. The feature runs through a general laid out system that matches the surrounding’s light sources. But it is important to note that everyone has different requirements and preferences when it comes to their brightness. The elderly people prefer higher brightness than the younger counterparts

The Operating system companies haven’t taken that into consideration or haven’t achieved it as of yet.

Another major downside of the auto brightness is that it has several complaints of draining your battery. The sensor calculates the surrounding’s light availability regularly throughout the day so it tends to take up a lot of the already short battery life of the iPhone and proves a pain for iPhone uses everywhere

These are the main reason iPhone users are constantly trying to keep their phone’s auto brightness feature switched off.

How to Calibrate your Auto Brightness – THE FIX

As mentioned above, you might be having issues with different requirements of the phone brightness, and surely the accuracy is improving in the recent version updates of the iOS. But a quick fix to this would be to calibrate the brightness level before switching on the auto-brightness (steps to that are given later in the article).

Go to a room (or a place) with minimal light and adjust your required brightness. And then when you switch on the auto brightness, your phone is calibrated to know what your requirements are. This does not always work effectively, but it is worth a try

The brightness bar is present in the control center. Hold it and pull to either side of your convenience

Alternatively, you could switch on the dark mode, use the night shift mode, or just the wallpaper dimming option if that’s what you want to go for instead of changing the brightness
