Grayscale Phone Benefits: Does Black and White Mode Work?
The main grayscale phone benefits are simple: your apps look less exciting, so you open them less and put the phone down sooner. Black and white mode will not fix a phone habit by itself, but it is a free, reversible speed bump, and there is some early research suggesting it can cut screen time.
If you are turning on grayscale because your focus feels fried, Brainrot Test checks how cooked your attention actually is and gives you a 2-minute drill a day to rebuild it. Check my brainrot
What grayscale mode actually is
Grayscale (UK spelling: greyscale) is an accessibility setting that removes all color from your screen. Everything turns shades of gray. Your red notification badges, the TikTok neon, the Instagram gradient, all gone.
It exists mainly for people with certain vision needs, but the "grayscale phone addiction" crowd borrowed it for one reason: color is doing a lot of work to keep you tapping. Bright red badges feel urgent. Saturated thumbnails feel exciting. Take the color out and your phone looks like a spreadsheet with a camera.
Quick vibe check on what changes:
- Feeds: Reels, Shorts and TikTok look flat and a bit sad.
- Notifications: badges still appear but stop screaming.
- Games: noticeably less fun (which is kind of the point).
- Photos and maps: annoying without color, which is why the shortcut below matters.
What the research says about grayscale and screen time
Here is the honest version. There is not a mountain of research on the grayscale phone setting, but there is some.
The one people cite most is a small study of US college students, published in The Social Science Journal by researchers at the University of North Dakota under the title "True colors: Grayscale setting reduces screen time in college students." Students tracked their normal screen time, then used grayscale, and their daily screen time went down during the grayscale period.
Things to keep in mind before you treat that as gospel:
- It was a small group of college students, not everyone.
- It was short, so we do not know if the effect lasts for months.
- People knew they were in a study, which can change behavior on its own.
So does grayscale help phone addiction? The fair answer: it looks like it can reduce use for some people, especially in the short term. That makes it worth trying, not worth worshipping. If you have seen "grayscale phone reddit" threads, the pattern matches. Lots of people say it helped for a few weeks, then they got used to it or started toggling it off.
| Claim you will see online | Honest take |
|---|---|
| "Grayscale cured my phone addiction" | It helped them. Results vary a lot |
| "Grayscale reduces screen time" | Early evidence says it can, short term |
| "Grayscale helps you sleep" | No solid proof. Less scrolling at night might help indirectly |
| "Grayscale fixes your attention span" | No. It reduces a trigger, not the habit |
How to turn on grayscale on iPhone
Here is the grayscale iPhone setting path:
- Open Settings.
- Tap Accessibility.
- Tap Display & Text Size.
- Tap Color Filters and switch it on.
- Choose Grayscale.
Your screen goes black and white instantly. If you want it only at night, you can also build an automation in the Shortcuts app that turns Color Filters on at a set time. (Shortcuts > Automation > Time of Day.)
How to turn on grayscale on Android
Android phones differ by brand, so the grayscale phone Android path depends on your model. Common routes:
- Digital Wellbeing bedtime mode (many phones, including Pixel): Settings > Digital Wellbeing & parental controls > Bedtime mode. Turn on the grayscale option so your screen goes black and white at bedtime automatically.
- Accessibility color correction (Pixel and others): Settings > Accessibility > Color and motion > Color correction > Grayscale.
- Samsung: Settings > Accessibility > Visibility enhancements > Color adjustment, then pick grayscale. Samsung's Bedtime mode also has a grayscale option in Modes and Routines.
If none of these match, type "grayscale" or "color correction" into the search bar at the top of Settings.
Set a shortcut so it is not annoying
This is the step every grayscale guide forgets, and it is why people quit. You need color back for 10 seconds to check a photo or read a map. If that takes six taps, you will just leave it off.
Triple-click on iPhone
Go to Settings > Accessibility > Accessibility Shortcut and select Color Filters. Now a triple-click of the side button (or the Home button on older iPhones) flips grayscale on and off.
Quick toggle on Android
Pull down Quick Settings, tap the edit (pencil) icon and drag in the Color correction tile if your phone offers it. Some phones also let you add an accessibility shortcut button. One tap and you are in color, one tap and you are back.
The rule: flip to color for a reason, flip back when you are done. Do not leave it in color "just for now."
What grayscale will not fix
Grayscale makes your phone less shiny. It does not change why you pick it up.
It will not fix:
- Boredom scrolling. If you open TikTok every time you are bored, you will still open it. It just looks worse.
- Notifications. A gray ping is still a ping. Turn off the ones you do not need.
- Your attention span. If long reading or long lessons already feel impossible, you need practice at focusing, not just a duller screen. Try our guide to getting back into reading after a slump.
- Habits tied to certain places. Scrolling in bed is about bed, not color. Charge the phone somewhere else.
This is where grayscale alone falls short: you cannot tell if your focus is actually improving. Brainrot Test gives you a quick check-in that finds your weak spot, then one 2-minute drill a day and a score that shows whether things are getting better while you run your grayscale experiment.

A two-week grayscale experiment
Treat it like a science project, not a lifestyle.
| Week | What you do | What you record |
|---|---|---|
| Week 1 | Normal color. Change nothing | Daily screen time, pickups, top 3 apps |
| Week 2 | Grayscale all day, triple-click for photos | Same numbers, plus how often you toggled |
At the end, compare. If screen time dropped and you did not hate it, keep it, maybe only in the evening. If nothing changed, grayscale is not your lever, and that is useful to know too. Pair it with other moves like the Following feed trick for Reels.
Grayscale phone benefits are real for some people and meh for others. Two weeks of data beats two hours of Reddit threads.
Know your focus score in a minute
Brainrot Test gives you a free check-in in your browser, with no download and no account needed to try. You get a score for how cooked your focus is, the weak spot behind it, and one 2-minute drill a day, so you can see whether grayscale plus a little practice is actually moving the number.
FAQ
Does grayscale help with phone addiction?
It can reduce how often you open apps, because color is part of what makes feeds exciting. A small study of college students found screen time went down in grayscale. It works best alongside other changes, like fewer notifications and charging your phone outside your bedroom.
What are the benefits of a grayscale iPhone?
Less tempting apps, calmer notification badges and a simple triple-click shortcut to switch color back on when you need it. It is free, built in and fully reversible.
Is grayscale good for your eyes?
There is no strong evidence that grayscale protects your eyes. Its main benefit is behavioral: you may use your phone less. If you have eye concerns, talk to an optician or eye doctor.
How do I make my phone black and white on Android?
Look in Settings > Digital Wellbeing > Bedtime mode for a grayscale option, or in Accessibility under color correction. Samsung puts it in Accessibility > Visibility enhancements. Search "grayscale" in Settings if you cannot find it.
Does grayscale mode save battery?
On most phones it does not make a meaningful difference, because the screen still lights up the same pixels. Any battery gain comes from using your phone less, not from the gray itself.
