The Truth About Why Your iPhone Screen Dims When Auto-Brightness is Off

The Truth About Why Your iPhone Screen Dims When Auto-Brightness is Off

Why my iPhone brightness keeps dimming - Every time you use your iPhone, it gets a little less awesome. At least in terms of how bright it is. The reason behind that is something called the ‘auto-brightness’ feature. This automatically dims your screen when there’s not enough light to see it in full brightness. If you don’t want to miss out on all the awesome highlights of life, here are some truths about why your iPhone screen dims when auto-brightness is off.


What is auto-brightness?

Auto-brightness senses the ambient light around your iPhone and adjusts the brightness of the screen accordingly. The iPhone screen brightness can be set to four brightness levels — Low, Medium, High, and Maximum. When the ambient light decreases below a certain threshold, the screen automatically thins out, thus reducing the amount of energy consumed and saving battery life. 

When the ambient light increases above a certain threshold, the screen automatically brightens up, increasing the amount of energy consumed and saving battery life. Auto-Brightness is a feature that can be really helpful, but it can also cause confusion. 

If you’re not sure what’s happening to your iPhone’s screen, you might end up accidentally adjusting the Auto-Brightness instead of turning it off. If you’re curious about what happens when your iPhone screen dims when auto-brightness is off, keep reading!


How does auto-brightness work?

As we mentioned above, auto-brightness can sense the ambient light around your iPhone, and then automatically adjust the screen brightness accordingly to save battery life. Specifically, it makes use of an ambient light sensor to measure the brightness of the surrounding light and then changes the screen’s brightness to the same level. 

The sensor needs to be able to sense the light so that it can respond to it, so it’s only found on newer iPhones. It’s possible that it’s also an improvement in sensitivity, since the iPhone 6 model was criticised for its low levels of sensitivity. 

The sensor itself may be a little less sensitive, too, since it’s likely that the sensor will be affected by other factors such as the surrounding reflective screen. As for why don’t want to miss out on all the awesome highlights of life, there are a few more things to consider.


Why does auto-brightness dim your iPhone screen?

As we mentioned above, the iPhone screen brightness can be set to four levels. When the ambient light decreases below a certain threshold, the iPhone screen dims. Exactly why it does that, well, that’s not necessarily the iPhone’s doing. 

It’s something that you can also do through the settings. In fact, there is a setting in the Accessibility section of the brightness slider in the General settings that lets you change the screen brightness to a specific level when auto-brightness turns it off. 

This means that you can control how dim or bright your screen gets when it senses that there isn’t enough light. The other thing to keep in mind is that when the iPhone screen dims, it also consumes less energy. So, if you want to save even more battery life when you can’t see your screen in full brightness, this is how you can do it.


So, how can we disable auto brightness on iPhones? 

The good news is that you can easily disable auto-brightness on your iPhone and save those batteries. Here’s how you can do it: Open up the Settings app on your iPhone. Scroll down to the Accessibility option and tap it. Now, change the ‘Auto-Brightness’ option from ‘On’ to ‘Off.’ That’s it! Now, your iPhone screen will be completely off when it senses that there isn’t enough light to see it in full brightness.


Conclusion

What happens when your iPhone screen dims when auto-brightness is off? It really depends on what’s causing the dimming — if it’s your own fingers (like if you bump into your phone or hit it with your hand while typing or reading), it’s not a big deal. Your screen will still be visible, but it will start to dim after a while. 

If it’s something else like sunlight, it’s not something that you can control, but at least there’s a fix for it. When auto-brightness is off, your iPhone screen will dim because it senses that there isn’t enough light to see it in full brightness.
