Reasons and solutions to adjust the brightness if this happens to you.
Mobile phones usually work very well both indoors and outdoors. That is thanks to the brightness level of their screens, which are able to light up when there is a lot of light and to dim when there is not. However, it can go dark without your permission, although you can adjust the brightness on your iPhone screen.
It is a failure that any Apple model can have and that is a headache for any user. However, there is a way to prevent the brightness from dimming on its own so you don’t have to manually adjust it every time.
Why does the screen brightness go down by itself
You may wonder why your iPhone changes the brightness of the screen depending on the situation or time of day. This is a matter of automatic brightness, since these mobiles use an ambient light sensor to adjust brightness levels depending on the lighting conditions of your environment.
It may happen that the brightness is lowered in a place with a lot of light, such as in the street in full sun. However, the reason may come from totally different factors, such as a temperature rise in the terminal. If the mobile gets very hot, it affects the screen by lowering the brightness.
It can also be a systematic failure of iOS, as in the iPhone 11 or iPhone 7, whose brightness is lowered only in both. For that, the only thing left is to try to solve it from within. And is that it won’t do any good if you take it to Apple tech support, because they will do a simple test and they will not solve it for you.
How to make the brightness not lowered?
To keep the brightness from dimming unexpectedly, there are several ways to fix it. If it’s because of the heat try to avoid exposing your iPhone to the sun or in a place where there are high temperatures. It is not the definitive solution, but it can help you avoid unexpected changes in brightness.
If the reason is not that, consider automatic brightness. And is that if you deactivate this function on your mobile, it will stop changing when it feels like it. You simply have to go to the Settings app, access the section “Accessibility“and enter”Screen and text size“. When you see the option.”auto brightness“, click on its button to deactivate it.
If you get to this step, keep two things in mind. The first is that you will have to manually adjust the brightness level every time you need it, being annoying even if it can be done directly from the Control Center. On the other hand, as the system warns you, this affects battery lifeespecially if you maintain a high brightness level at all times.
You can do this on any model, since all iPhones are susceptible to this automatic brightness failure. However, if in your case you have an iPhone 11 or an iPhone 7, you will probably not have results with the previous method. Many users have tried this method with little success.
Before you panic and go to technical support, you must do something else from the Settings app to fix this. You can try activating the True Tone and automatic light adaptation to fix it, but it may fail again after a while.
The definitive and permanent solution seems to be in the section of “Accessibility“, but with a different route. Instead of going in to deactivate the automatic brightness, go to”Zoom” To access “Zoom filter“. In that menu, you have to select, from among all the possibilities that there are, the option”None“Virtually all users who have had this problem have been solved by doing this process.
It seems that the brightness of the iPhone is lowered only because of a problem with the zoom filter, a function that enlarges the content of the entire screen and makes it easier to see it. It is not like increasing the font size on iPhone, but it is similar. However, you have other alternatives in case this doesn’t work for you.
