The screen of the iPhone could be brighter and brighter than it is

When you want to increase the brightness of the iPhone screen, you will likely use the brightness slider in Control Center, especially if you have disabled automatic brightness. But once the maximum is reached, it seems to you that the screen cannot get any brighter. However, depending on your iPhone model, your screen may be brighter depending on how you use it.

In fact, many iPhones have two different levels of maximum brightness depending on what is displayed on the device. The second level can be achieved thanks to something you are already familiar with - laying HDROr, high dynamic range, to allow the iPhone to lighten the lighting areas in the image more than usual, which creates a dynamic contrast between the light and dark areas of the screen.

For example, you can clearly see what is displayed on the screen in a dark room next to a bright open window. But the image may be slightly muted compared to an HDR screen, which can raise the brightness while preserving the overall picture quality.

There are tons of HDR use cases. You also benefit from the videos you shoot on iPhone using HDR or Dolby Vision HDR. Even images captured with HDR, which are supported by many cameras, can be enjoyed best on the brightest screen setting.

When viewing this HDR content, the bright areas on your iPhone screen become brighter than usual. IPhone 12 has a maximum brightness of 625 nits per square meter (a candle is the Arabic variant of the word nits in English, meaning 625nits lighting), but the system can nearly double this brightness to 1200 nits when playing HDR content. This is much brighter than the Brightness slider in Control Center might offer.

This feature is only available on certain iPhone models. You will not find it on any devices with an IPS screen, such as the iPhone 11 or iPhone 8 Plus. You also won't see it on all OLED screens, unfortunately, iPhone X and iPhone XS users as well. Apple implemented this feature for the first time by introducing Super Retina XDR screens to the iPhone 11 Pro and 11 Pro Max and has since added it to all models equipped with Super Retina XDR screens.

And if you care about more details, here is the list of supported phones

IPhone 12 and 12 mini 625 nits by default increases to 1200 nits in HDR mode

IPhone 12 Pro and Pro Max: 800 nits by default, which increases to 1200 nits in HDR mode

IPhone 11 Pro and 11 Pro Max: 800 nits by default, which increases to 1200 nits in HDR mode

Remember: the default number is the maximum brightness level that an iPhone can reach during normal use. Both the iPhone 12 and 12 mini have a maximum brightness of less than the Pro series, but all supported iPhone models have the same maximum brightness of 1200 nits. Any of the iPhones mentioned above can take advantage of the variable screen brightness when playing HDR content.

To achieve this you have to turn off automatic brightness and make it manual and check the Control Center brightness slider to ensure that it is at its highest when viewing HDR content because it will likely not work if you use auto brightness.

After all, your iPhone's screen may not stay bright throughout its life. As Apple mentioned in its OLED explanation, screen technology is affected by usage and time and may lose peak brightness over the course of its life. Although the iPhone 11 Pro might be able to reach 800 nits during default use and 1200 nits when playing HDR content, it might not look as bright after a few years.

That's why Apple recommends keeping auto brightness enabled so that iOS can keep the screen at optimum brightness levels for your environment at all times. If you don't use your iPhone outside all the time, a lower brightness setting should, in theory, keep your screen's maximum brightness at higher levels for a longer period of time.

However, many of us choose to disable auto-brightness. In fact, brightness issue is not a common complaint among iPhone users, so it comes down to personal choice.
