As a battery-saving measure, yourautomatically adjusts the brightness of your screen depending on the light in your environment. The less light there is around you, the dimmer your screen becomes – but that may not be what you want.
Even when it’s dark, you may want to keep your iPhone’s brightness high because it will help you see what’s on the screen, whether you’re reading an article or watching a movie. However, solving this problem isn’t always as simple as disabling an automatic brightness setting, although that’s a good start.
In this guide, we’ll show you two settings that you should turn off to prevent your iPhone from dimming automatically. And how your iPhone can adjust brightness even with those two settings turned off if you’re not careful.
While you’re here, you should also check out. And this one .
First turn off auto brightness
Yes, this may seem a bit obvious, but the first thing you’ll want to do is make sure auto-brightness is turned off in your settings. The function is self-explanatory: it automatically adjusts your brightness depending on the light in your environment. But if you want to prevent your display from always trying to adjust, you should disable this feature.
In the Settings application, go to Accessibility > Display and text size and switch off Automatic brightness at the bottom of the page. You would think this setting would exist in Display and brightnessso it’s not uncommon for auto-brightness to turn on without you actually knowing, as it’s tucked away in Accessibility.
If your brightness keeps adjusting automatically, there’s another setting you need to turn off.
You should also disable True Tone
If you iPhone SE (2nd generation) and laterthe True tone function has the ability to measure the color temperature and brightness in your environment and then adjust the display. True Tone is useful – not only does it help display more accurate colors in different lighting situations, it’s also easier on the eyes, which you need if you’re constantly reading on your phone.
Again, if you don’t care for the feature, don’t use it, or are just annoyed that your brightness keeps adjusting automatically, you should disable it. In Institutionsgo to Display and brightness and switch off True tone below the Brightness header. As long as auto-brightness is turned off as well, disabling True Tone should prevent your iPhone from automatically adjusting your brightness.
However, there is one exception.
Don’t let your iPhone overheat
Your iPhone has several ways to protect its internal components, including automatically dimming your screen. Even if you have both Auto Brightness and True Tone turned off, if youit will automatically adjust the display intensity.
According to AppleTo help prevent this, use your iPhone in temperatures between 32 and 95 degrees F (zero and 35 degrees C) and store it at temperatures between 4 and 113 degrees F (between 20 below zero and 45 degrees C). If you leave your iPhone in your car or on the sidewalk on a hot day, chances are it will overheat, automatically dimming your screen.
However, overheating is not only caused by a sunny day. A faulty battery can cause your iPhone to overheat: Go to Institutions > Battery > Battery status and charging and check if your battery needs to be replaced. Another reason could be buggy software: Go to Institutions > General > Software update and make sure you are always on the latest update to fix any software bugs and issues.
