Get Flux-like Low Light Display Brightness On iPhone & iPad Without Jailbreak

Flux on desktops can change display color, and radically reduce display brightness. iOS comes with a similar functionality for the latter feature. It is hidden deep down in the Accessibility Settings, and we will show you how to enable Flux-like Low Light mode in iOS without jailbreaking in a few steps.

I simply cannot use my computer without Flux installed. It’s an excellent utility that dynamically changes the color of your screen display so that it is easier to look at at night. Flux also comes with a useful feature which can lower display brightness beyond what the hardware supports through the power of a software-based filter.

Since Flux makes system-level changes – change of color and reduced display brightness – and since iOS does not allow apps to make system-level changes, Flux cannot exist on iOS without Apple making important changes to what third-party apps can and cannot do.

There is, however, a bit of a functionality baked right into iOS that mimics part of what Flux can do on desktops. If one of the main reasons why you use Flux is because it makes it significantly easier to use your computer in severe low-light conditions (such as when you wake up in the middle of the night to reply to a text, or jot down an important idea), then Low Light mode in iOS will be equally useful for you.

  1. Go to Settings > General > Accessibility > Zoom
  2. Turn on Zoom
  3. Using three fingers, quickly tap three times anywhere on the iPhone or iPad’s screen.
  4. Tap on Choose Filter
  5. Select Low Light

Like Flux, this quite literally adds a software-based, system-wide filter which radically reduces display brightness. If you usually keep your display brightness below 40-50%, you might as well apply this Low Light filter which will dramatically improve reading experience in low light, while not radically affecting how you use your phone in daytime.

Seeing as how Apple did finally open up to ‘Custom Actions’ and ‘Extensions’ in iOS 8, I do genuinely expect Apple to allow system-wide tweaks in the future. Combined with Apple’s strong curation of App Store apps, there is very little chance that a malicious app may cause system-level havoc.

I would show a comparison screenshots showing display brightness before and after applying Low Light mode, but iOS disables Low Light mode before saving screenshots. You will have to experience it yourself!

  1. Thanks for your info on low light for iPad.
    I use Flux low light on my computer all the time due to
    migraines as well as sleep problems.
    I did not know about the iPad low light feature.
    I knew you could add Flux if you jailbreak the iPad but I’ve been
    hesitant to do that.

  2. Thank you so much for the post! You have saved a student’s eyes from fatigue. The full screen option is awesome since the lowest setting on the ipad isn’t enough and my books are on here.

  3. I don’t understand how this is supposed to work. The filter option in zoom merely changes how the zoomed area looks, not the normal unzoomed screen.

      1. Thank you for this explanation Davide. I kept following the instructions with no successful until I read your post.

  4. Perfect (aside from keys and buttons “sticking”)! Thanks so much for the explanation! <3

  5. Been using this technique for a year or so, and love it. But when it comes to reading, changing the color gamut like f.lux can do can’t be beat.

  7. This is a useful tip, especially for night-time, but calling it “Flux-like” is misleading. Flux does nothing to the brightness most of the time, only colour change.

    Also, I find that in almost all cases, night-time reading is best done without the zoom filter, but instead with reduce white point and invert colours both turned on. This is due to the fact that the zoom filter reduces the contrast of the display.
