Currently, as you surely already know, most mobile phones developed by Samsung, Xiaomi, Motorola or Huawei incorporate a feature called “automatic brightness”. You must have already seen it: it is her job to automatically reduce or increase the brightness of the screen, depending on the lighting conditions where you are. So, for example, when you use your Smartphone in a very bright place, such as outdoors, the lighting level is the highest to allow you to correctly view all the icons on the screen, your messages or your notifications, among others. Of course, conversely, in the evening, if the room is very dimly lit, the brightness will decrease sharply, by half or even a little more.

Why not turn off auto-brightness?

Well, now, it is clear that this function is very mixed. As it is activated by default, some people use it willingly to avoid complicating their lives. They trust her and let her manage this aspect. On the other hand, others seem more capricious. Many Android users are not convinced by this feature and prefer to disable it altogether. In other words, they choose the brightness level of their screen themselves. Good or bad idea ? According to the experts, this practice is far from beneficial. Because most users very quickly get used to adjusting it to the maximum. They believe, wrongly, that comfort is there!

Yet, strangely, many of them did complain of eyestrain or headaches. Nothing surprising in this, especially if you spend many hours at night (or early in the morning) in front of your mobile. And, in addition to these effects on health, they also often notice that the autonomy of their Smartphone is greatly reduced. Again, it’s completely normal for the battery to drain faster when the screen is constantly at maximum brightness. Result: you find yourself recharging your laptop every four or six hours! There is no mystery: by keeping the automatic brightness, all these inconveniences would no longer be relevant.

What is the right level of brightness for the screen of a Smartphone?

Whether Android or iOS, to keep your eyes healthy, the best screen brightness should be around 30% or less indoors (or in a dark room) and 50 or 60% outdoor under sunlight. Outside, preferably, you should even use the adaptive screen brightness mode, it is very useful. But, ideally, it would always be wiser to leave it to automatic brightness. It has been precisely programmed to better manage the different lighting conditions in order to make things easier for you. So why deprive yourself of it?
