So you want to know how to turn on dark mode? Smart move. I switched everything to dark theme three years ago and honestly? My eyes thank me every evening. That harsh white light when you're checking your phone at 2am? Yeah, not fun. Let's fix that for you.
Why bother with dark mode? Beyond looking cool, it reduces eye strain big time (especially in low light), can save battery on OLED screens (up to 60% on phones!), and helps some folks focus better. Plus let's be real - it just looks more modern.
The Full Dark Mode Setup Guide
I'll walk you through turning on dark mode for every device and app you use daily. These are the exact steps I've tested myself - no fluff. And hey, if something doesn't work perfectly? I'll tell you straight up.
Turning on Dark Mode in Windows 10 and 11
Windows makes it pretty straightforward:
1. Right-click your desktop and select "Personalize"
2. Choose "Colors" from the left menu
3. Under "Choose your mode", pick "Dark"
4. Want dark File Explorer too? Scroll down to "Choose your default Windows mode" and select "Dark"
Pro tip: In Windows 11, you can create custom schedules. I have mine switch automatically at sunset using the "Sunset to sunrise" option under "Choose your default app mode".
Activating Dark Mode on Mac
Apple's macOS has the slickest dark mode implementation in my opinion. Here's how to turn on dark mode:
1. Click the Apple menu > System Settings
2. Go to "Appearance"
3. Select the "Dark" option
| Mac Version | Where to Find Settings | Special Notes |
|---|---|---|
| macOS Ventura (13) | System Settings > Appearance | Dynamic wallpaper adapts to dark mode |
| macOS Monterey (12) | System Preferences > General | Auto-switch based on time available |
| Older Versions | System Preferences > General | Limited app support |
Annoyance alert: Some third-party apps ignore system settings. You'll need to enable dark mode separately in apps like Adobe Creative Cloud.
Dark Mode for iPhone and iPad
iOS dark mode is super flexible. Two main ways to turn on dark mode:
Manual Control:
1. Open Settings
2. Tap Display & Brightness
3. Select Dark under Appearance
Automatic Schedule:
1. Same path: Settings > Display & Brightness
2. Tap Automatic
3. Choose Sunset to Sunrise or set custom hours
Heads up: Some older apps won't comply even with dark mode on. Instagram took forever to add proper dark mode support - drove me nuts last year.
Dark Mode on Android Devices
Android setup varies by manufacturer. Here's the standard way to turn on dark mode:
1. Pull down notification shade twice
2. Tap the gear icon (Settings)
3. Go to Display > Dark theme
4. Toggle on "Use dark theme"
| Brand | Special Instructions | Battery Savings |
|---|---|---|
| Samsung | Quick Settings tile available | Highest savings (OLED screens) |
| Google Pixel | Scheduled dark mode in Display settings | 40-60% on dark screens |
| OnePlus | Custom accent colors possible | Moderate savings |
Personal gripe: Why can't all Android skins just use the standard method? Xiaomi hides it under Additional Settings - took me ages to find.
Web Browsers Dark Mode Settings
Want to turn on dark mode for your browsing? Here's how:
Chrome Desktop:
1. Install 'Dark Reader' extension
2. Click icon and toggle on
(Native dark mode coming soon)
Firefox Desktop:
1. Go to about:config
2. Search 'darkmode'
3. Set 'layout.css.prefers-color-scheme' to 1
Honestly? Browser dark mode is still messy. Some websites implement it poorly with unreadable text. I wish all sites just respected system settings.
Essential Dark Mode Troubleshooting
Sometimes turning on dark mode doesn't go smoothly. Based on helping dozens of friends:
Problem: App ignores dark mode setting
Fix: Check app settings first (many have separate toggle)
Example: Gmail has its own dark mode toggle under Settings > Theme
Problem: Text becomes hard to read
Fix: Adjust contrast in system accessibility settings
Personal hack: I use browser extensions to force better contrast
Warning: Dark mode can actually cause issues for some people with astigmatism. If you get headaches, try switching back or reducing contrast.
Dark Mode Beyond the Basics
Automating Your Dark Mode
Manually turning on dark mode gets old. Automation options:
Windows: Task Scheduler with custom scripts
macOS: Built-in scheduling in System Settings
iPhone: Shortcuts app can toggle with location/time
Android: Tasker app ($3.49) for advanced automation
Dark Mode for Specific Apps
Some apps need special attention when learning how to turn on dark mode:
| Application | How to Enable | Special Notes |
|---|---|---|
| Menu > Settings > Dark Mode | Three shade options available | |
| YouTube | Profile pic > Appearance > Dark theme | Different from system setting |
| Microsoft Office | File > Account > Office Theme | Choose "Black" for true dark mode |
| Settings > Chats > Theme | Can schedule auto-dark |
Dark Mode FAQ Section
Does dark mode really save battery?
On OLED/AMOLED screens? Absolutely. My Pixel 7 gets about 30% longer battery life with dark mode enabled. LCD screens? Sadly no real savings.
Why doesn't dark mode work on some websites?
Because developers need to implement it properly. Try extensions like Dark Reader (works on 95% of sites in my experience).
Can dark mode help with eye strain?
For most people at night - yes. During daylight? Actually less effective according to recent studies. I keep mine scheduled.
Is there any downside to dark mode?
Some studies suggest reduced reading comprehension for long texts. Personally I switch to light mode when reading novels on my tablet.
How do I turn on dark mode for specific apps only?
Most apps have their own settings. For system-wide control without affecting specific apps - sorry, not really possible yet.
Final Dark Mode Tips
After three years of living in dark mode, here's what I've learned:
• Reduce screen brightness when using dark mode at night - your eyes will adjust better
• Schedule automation - manual toggling gets tedious fast
• Experiment with different dark shades - some grays are easier on the eyes than pure black
• Give your eyes 2-3 days to adjust before deciding if you like it
• Combine with blue light filters for maximum eye comfort
• Not everything needs to be dark - my Kindle stays happily in light mode
Learning how to turn on dark mode properly changed my digital life. That said, it's not perfect everywhere yet. I still curse when I open some government website that blinds me at night. But overall? Best decision ever for my evening browsing sessions.
