Turn Off Auto-Brightness on iPhone

The iPhone has a lot of amazing features that make it an easy sell for most people but it also has some quirks that require extra attention. For instance, when they removed the battery percentage sign from the status bar, I had to find ways around it. Similarly, the iPhone has an auto-brightness feature that is enabled by default and unlike Android smartphones, the option to disable isn’t anywhere in sight. If you’ve been irritated by your screen brightness adjusting automatically, here’s an easy way to turn off auto-brightness on iPhone. Let’s begin.

Why is Auto-Brightness This Finicky?

No, Apple didn’t gloss over this important feature, they just tried to implement a method that makes the brightness adjustment automatic and organic so you don’t notice it that often. However, if you’re unaware of how it works and you’ve been manually adjusting it to your levels and then finding out the iPhone has adjusted the brightness to a different level. It’s by design.

How Does Auto-Brightness Works on iPhone?

The iPhone uses the inbuilt ambient light sensor to adjust the brightness according to your surroundings. So if you’re in a dark room, the iPhone would gradually lower the brightness levels and similarly increase it when you move to a well-lit place.

However, if you set the brightness manually in any setting then the iPhone would only go to that level of brightness. For instance, if you lower the brightness to 20% in a completely dark room, it would never go below that level automatically until you manually adjust that level. Alternatively, if you ramp up the brightness to only 50% under a bright sun, the iPhone would learn to not take the brightness up beyond that point. This would lead to your iPhone brightness going down when you go to a less bright place such as a normal room.

This is why you may find the Auto-Brightness feature irritating as it is lowering the brightness in a well-lit room. Whereas in reality, it is working as intended and you set it to go to 50% brightness in a super bright environment.

Closing Words: Turn Off Auto-Brightness in iPhone

This was a quick way to turn off the auto-brightness feature on your iPhone. Mind you, turning off the auto-brightness can reduce your iPhone’s battery life if you keep it at extremely high brightness. A better solution is set to set your own personal high and low points so auto-brightness won’t breach those levels. What do you think? Did you know how the auto-brightness worked on iPhone?
