Does your iPhone screen continue to darken or turn off while reading something, checking a shopping list or any other time you do not want it to? There is an easy way to fix it in Settings. Here̵7;s how.
The reason why your iPhone continues to dim and turn off is due to a feature called “Auto-Lock”, which automatically puts the iPhone to sleep after a certain time. Two-thirds of the way through the set period, the screen decreases to half brightness. To fix this we have to turn off “Auto-Lock”.
First open the “Settings” app by tapping the “gear” icon.
Touch “Screen and Brightness” in “Settings”.
In the “Screen and brightness” settings, scroll down and press “Auto lock”.
(Note: If you have activated the low power mode, Auto-Lock will be “30 seconds” and you will not be able to press the option to change it. To change it, first deactivate the low power mode.)
“Auto lock” displays a list of time options. These determine how long your iPhone’s screen stays on before it turns off and enters lock mode.
Here we will turn it off completely, so select “Never”.
Then exit Settings. When you wake up your iPhone, the screen stays lit and does not enter lock mode until you press the power key.
If you continue to have problems with a dimming screen even if “Auto-Lock” is disabled, it may be because “Auto-Brightness” is enabled. “Auto brightness” can be disabled under the availability options in the Settings app.

It is usually best to re-enable auto-lock again later
There are some disadvantages to disabling “Auto-Lock”. The first is the battery life: Your phone will run out of battery power much faster if you forget to turn off the screen. The second is security: If you leave the phone on and it does not lock automatically, anyone can use it.
So it may be best to activate the “Auto-Lock” function again when you are done. To do so, just repeat the steps above and select a time limit from the list instead of “Never.” Good luck!
