Hidden trick to dim your iPhone and iPad screen
Even on the lowest available brightness setting the iPhone or iPad’s display can be too bright. This is certainly the case when you’re reading in bed at night or simply trying to look at something in the dark. If you’re finding the light is still too harsh for your eyes, there’s actually something you can do.
It turns out the lowest setting on the brightness slider isn’t the dimmest the iPhone or iPad can go. Here’s how to get your iPhone or iPad’s brightness extra-dim for any night-time reading you might need to do.
1. Go to Settings > General > Accessibility > Zoom.
2. At the top of the Zoom page, slide the toggle switch to turn on Zoom.
3. Scroll down on the Zoom page and click on Zoom Region and turn on Full Screen Zoom.
4. Go back to Zoom page and click on Zoom Filter and select Low Light.
With the zoom function enabled on your Apple device, double tap with three fingers to zoom in or out. The low light filter will stay in place either way. To get out of the low-light filter, follow the above instructions and unselect Low Light. You could also unselect the Zoom function, which will disable the Low Light filter as well.
