iOS makes it very easy to adjust the screen brightness using the dedicated slider available in Control Center. While the Control Center is just a swipe away, it can be inconvenient to use it when you’re watching something (like a movie or a YouTube video) or playing a game.
Nevertheless, if you have a jailbroken device, there’s a new tweak called VolBright that lets you control display brightness on your iPhone using volume buttons.
Control display brightness on your iPhone using volume buttons with VolBright tweak
By default, the volume buttons are obviously used to change the media and ringer volume levels, but VolBright is able to reassign their functions to controlling display brightness. Since technically, you’re still going to need them to perform volume adjustments VolBright only works if the mute switch is off.
So, while the mute switch is enabled, the volume buttons will have their default function, specifically for adjusting your iPhone’s volume. When the mute switch is turned off, VolBright comes into play, allowing you to control the display brightness on your iPhone using volume buttons.
Nevertheless, you get to choose if the tweak is enabled when the mute switch is on or off from VolBright’s configuration screen available in the Settings app.
Furthermore, the tweak can be manually enabled/disabled as needed, using the dedicated toggle. Typically, invoking the Control Center to change screen brightness is convenient enough, but it does take up a lot of screen space, so VolBright is a simpler option when multitasking.
If you’d like to try VolBright, you should know the tweak is free and available for download in Cydia’s BigBoss repo.
