iPhone fans have just discovered a hidden 'red mode' introduced in last year's iOS update. The feature initially left some users worried that their devices had suffered water damage or been hacked. However, it was specifically designed to help users relax and sleep better at night as research has suggested that red lights have no effect on the circadian clock.

The so-called 'red mode' was introduced with Apple's iOS 17 operating system as part of StandBy -a customizable version of the Lock Screen that activates when the iPhone is charging and placed on its side in landscape mode. To activate the colored feature, you can either use the Color Filters feature to apply a red tint or enable Night Mode in StandBy to adjust the screen's colors to red.

To enable Color Filters, go to Settings > Accessibility > Display & Text Size > Color Filters. Alternatively, activate StandBy in Settings, connect your iPhone to a charger, and place it on its side. 'You can use StandBy to turn your iPhone into a bedside clock, a photo frame, or a display for widgets or Live Activities in full screen,' the tech giant explained.
While some have worried that the blood red screen (pictured) is a sign of water damage, or hackers, or something even worse, the truth is that this surprising color change is a new feature designed to help iPhone owners and their loved ones get a good night's sleep.
