How Do I Stop My iPhone From Dimming Automatically?
If you want to stop your iPhone from dimming on its own and take complete manual control over the brightness of the screen, then the first step is to disable Auto-Brightness. That will prevent your iPhone from automatically adjusting its screen brightness based on ambient light conditions. If you want to take total control, you’ll need to also disable the Night Shift feature. Here’s how to disable Auto-Brightness on an iPhone:
How to Turn Off the iPhone Night Shift Feature
In addition to the Auto-Brightness feature, the brightness of an iPhone display can also be reduced by the Night Shift feature. Turning off both Auto-Brightness and this feature will prevent the iPhone display from adjusting automatically at all, so you will have to adjust it yourself using the Control Center. Here’s how to turn off Night Shift on an iPhone:
How to Adjust Your iPhone Brightness Manually
When you turn off Auto-Brightness and Night Shift, your iPhone will no longer adjust its brightness in response to lighting conditions or the time of day. You may find the display is too bright at night after making these changes, or it’s difficult to see in bright sunlight. If so, you’ll have to adjust the brightness manually each time you want the display to be brighter or find it to be too bright. Here’s how to adjust your iPhone display brightness:
Why Does My iPhone Keep Lowering the Brightness?
Your iPhone is designed to automatically change its brightness throughout the day based on the current conditions. Depending on the time of day and your current lighting conditions, either one of these features could be responsible for your phone lowering brightness. There is also a low power mode that kicks in when your battery is close to running out.
Here are the features that can lower the brightness of an iPhone:
Auto-Brightness: This feature uses the light sensor that’s built into your iPhone to match screen brightness to your current lighting conditions. If you’re in a brightly lit room, this feature will adjust your display to be brighter. In a darker room, the brightness will go down. This can help reduce eye strain. Night Shift: This feature adjusts the brightness and color temperature of your iPhone screen based on the time of day and your location. When it’s on, the brightness will lower and the screen temperatures will shift at sunset to reduce eye strain. Low Power Mode: This feature activates when your battery drops below a critical level. Low Power Mode adjusts a number of settings to increase battery life, which includes lowering screen brightness. You can turn this mode off in battery settings, or plug your phone in and let it charge.
