Although auto-brightness is meant to make life simpler, it sometimes makes your screen adjustments at the most inconvenient moments. That may be resolved by turning off these iPhone settings.
Not all of your iPhone’s settings are always useful. Even if the lighting around you changes, auto-brightness is meant to make it easier to view your screen. To make sure you’re not straining your eyes to see what’s on your phone, sensors adjust the brightness based on the light levels around you. Nevertheless, this specific trait may prove to be more detrimental than beneficial.
The issue could be that when you’re in the sun, your display automatically dims. Your phone may be misled into automatically darkening your screen if you’re partly in the shadow, even if it doesn’t have to. It may get challenging to see what’s on your screen as a result. Because of auto-brightness, if you manually raise the brightness, it will just drop again. Although turning off the required settings isn’t always the easiest approach to resolve this problem, it’s an excellent place to start.
To assist stop your iPhone from dimming itself, we’ll show you two options you need to turn off. Note that even if you deactivate those two options, your iPhone may still automatically alter its brightness.
Turn off auto-brightness first.
Yes, this may seem a little self-evident, but the first thing you need do is check your settings to make sure automatic brightness is turned off. The function is quite self-explanatory: it automatically adjusts your brightness based on ambient light. You must turn off this function if you want to stop your display from constantly attempting to adapt.
Toggle off Auto-Brightness at the bottom of the page by selecting Accessibility > Display & Text Size in the Settings app. Since auto-brightness is hidden under Accessibility, it’s typical for it to be activated without your knowledge. You would imagine that this option would be found in Display & Brightness. You must turn off another option if your brightness keeps changing on its own.
Additionally, you must disable True Tone
The True Tone function on iPhone SE (2nd gen) and subsequent models detects the brightness and colour temperature of your surroundings and modifies the display to fit. When you need it, True Tone is helpful since it’s gentler on the eyes, which is important if you read on your phone all the time. It also helps display more realistic colours in different lighting conditions.
Once again, you must deactivate the function if you don’t want it, don’t use it, or are just upset that your brightness keeps changing on its own. Toggle off True Tone under the Brightness heading under Display & Brightness in Settings. Turning off True Tone should stop your iPhone from automatically altering your brightness, provided that auto-brightness is likewise turned off. There is one exception.
Keep your iPhone from overheating
One of the ways your iPhone protects its internal components is by automatically lowering the screen’s brightness. Your iPhone will automatically alter the display intensity if it is overheating, even if you have both auto-brightness and True Tone turned off.
Apple advises using your iPhone at temperatures between 32 and 95 degrees Fahrenheit (zero to 35 degrees Celsius) and storing it in temperatures between 4 and 113 degrees Fahrenheit (minus 20 to 45 degrees Celsius) to help avoid this. On hot days, there’s a significant risk that your iPhone may overheat and cause your display to dim if you leave it in your vehicle, on the pavement, or even if you attempt to use it near the beach or pool.
It’s not only sunny days that induce overheating. Your iPhone may potentially overheat due to a malfunctioning battery. To determine if your battery needs to be changed, go to Settings > Battery > Battery Health. Software bugs might be another factor. To address any software defects or difficulties, make sure you are always on the most recent version by going to Settings > General > Software Update.
