iPhone, as you know, can independently adjust the brightness levels of its own display, depending on the conditions of external lighting. However, quite often it happens that with the proper quality and efficiency, such automatic adjustment on the iPhone for some reason does not work.
The result is a problem, even two: the display does not behave quite adequately – this is, firstly, and secondly, such unsuccessful “maneuvers” with a brightness level have a bad effect on the autonomy of the smartphone, i.e. His battery sits faster.
Fortunately, the cause of this indecency, as a rule, is the incorrect operation of the built-in ambient light sensor.
Therefore, the user can eliminate the trouble on his own, if, of course, the problem is precisely in this, and not, for example, in the undesirable mechanical effect on the smartphone itself or its individual elements.
In other words, if the device has not been beaten and broken so that you cannot do without replacing the iPhone 5 display or other serious repairs, then you can configure the sensor without the help of a service center wizard.
The fact is that, perhaps, secretly anticipating this kind of trouble with the light sensor, in general, and the automatic brightness adjustment mode in particular, the creators of the iPhone 5 prudently left the user the opportunity to manually configure them.
In general, if different things suddenly started to happen with automatic brightness control in your iPhone, which makes your eyes uncomfortable, you will have to intervene in person and, after spending a couple of minutes of your time, resolutely fix the problem.
So, how to set up automatic brightness control in iPhone 5?
To begin with, we note that in order to qualitatively adjust the auto-adjustment of the screen brightness in the iPhone, you will need a bright flashlight (the sun does not fit) and a dark room (the level of darkness should be close to the "pitch" indicator). All this is necessary in order to properly calibrate the sensor. Now:
1. Go to the "Settings" of the smartphone.
2. Select the tab “Brightness and Wallpaper” (Brightness & Wallpaper)
3. By default, the window that appears should look something like this:
4. We go into a dark room (or turn off the light in a bright room), we bring with us an iPhone and a flashlight. In the dark, turn off the Auto Brightness mode on the iPhone. Now that the automatic screen brightness adjustment in the smartphone is turned off, you can manually set the brightness level that suits you best if it is dark around. We install and wait a couple of seconds until the settings are saved.
5. Next, turn on the flashlight, bring it as close as possible to the front camera of the iPhone, and again set the screen brightness level to the optimum level (most likely, the slider will need to be moved to the extreme right position or very close position, that is, to almost 100% brightness) . Thus, we show the light sensor conditions similar to a bright sunny day. We’ll also wait a bit while the device resembles the new settings.
6. Turn off the flashlight, exit the dark room and turn on the "Auto Brightness" mode on the iPhone. The new settings will be accepted by the system, and you will see how the screen of the device again began to adapt to external light, but already correctly.
