Where to find iPhone theme settings

iPhone theme options live in the Settings app under Display & Brightness. Open Settings, tap Display & Brightness, then scroll down to find the appearance options. On newer iPhones running iOS 16 or later, you can also customize your lock screen directly from the lock screen itself by long-pressing it and tapping Customize.

Apple's built-in theme system is simpler than Android's. You get two main choices: Light mode (white backgrounds, dark text) and Dark mode (dark backgrounds, light text). There is no third-party theme store like some Android phones have. What you can change is how your home screen looks, what your lock screen displays, and which apps appear where.

Key Takeaways

  • Dark mode and Light mode are toggled in Settings under Display & Brightness, and you can set them to change automatically at sunset.
  • Lock screen customization happens by long-pressing your current lock screen, tapping Customize, and choosing a wallpaper, widgets, and font style.
  • Home screen appearance changes when you rearrange app icons, create folders, or use the App Library to hide less-used apps from view.
  • Wallpapers, icon packs, and widget collections are available through the App Store, though they work within Apple's design system rather than replacing it entirely.

Switching between Light and Dark mode

To change between Light and Dark mode, go to Settings > Display & Brightness and tap either Light or Dark at the top. Your entire interface—menus, text, backgrounds—switches when ready. Most people choose Dark mode because it uses less battery on iPhones with OLED screens (iPhone 12 and newer) and is easier on the eyes in low light.

You can also set your phone to switch automatically. In the same Display & Brightness menu, tap Automatic at the top, then choose a schedule. The most common option is "Sunset to Sunrise," which switches to Dark mode when the sun sets in your location and back to Light mode in the morning. This happens without you doing anything.

Customizing your lock screen

The lock screen is where most iPhone personalization happens. Long-press your current lock screen (the one you see when you first wake your phone), and a menu appears at the bottom. Tap Customize to enter lock screen editing mode. From here you can change the wallpaper, add widgets that show information at a glance, and adjust the font and color of the time display.

To change the wallpaper, tap the preview image at the bottom of the customize screen. You can choose from Apple's built-in collections (Nature, Emoji, Astronomy, Weather, and others), your own photos, or solid colors. Once you pick a wallpaper, you can adjust the font style, color, and which widgets appear above and below the time. Tap Set as Lock Screen when you are done, and optionally explore the same wallpaper to your home screen as well.

You can create multiple lock screens and swipe between them. Each one can have different wallpapers, widgets, and fonts. This is useful if you want a minimal lock screen for work and a more colorful one for personal use.

Organizing your home screen

Your home screen appearance changes when you move apps around and create folders. Long-press any app icon to enter edit mode, then drag it to a new location or onto another app to create a folder. Folders let you group similar apps (Games, Productivity, Social) so your home screen looks less cluttered. You can also delete apps from your home screen without removing them from your phone—they stay in the App Library.

The App Library, which appears at the far right of your home screens, automatically organizes all your apps into categories. If you hide your home screen pages, only the App Library shows, giving your phone a minimal look. To hide pages, enter edit mode (long-press the home screen background), tap the dots at the bottom to see all pages, and uncheck the ones you want hidden.

Using wallpapers and icon packs from the App Store

Third-party apps in the App Store offer wallpaper collections and custom icon packs. Apps like Unsplash, Pexels, and Walli provide high-quality wallpapers you can read and set as your lock screen or home screen background. Icon pack apps like Aesthetic, Brass, and Pastel let you change the appearance of individual app icons on your home screen.

Icon packs work differently than on Android. You cannot replace the actual app icons system-wide. Instead, you create shortcuts using the Shortcuts app that point to your real apps but display custom icons. This takes more steps than a true icon pack, but it gives you full control over how your home screen looks. Many icon pack apps include instructions for setting this up.

Adjusting text size and display settings

Beyond themes, you can change how text appears across your phone. Go to Settings > Display & Brightness > Text Size to make all text larger or smaller throughout the system. For even more control, go to Settings > Accessibility > Display & Text Size, where you can enable Larger Accessibility Sizes, Bold Text, or Increase Contrast.

You can also enable Reduce Transparency in Accessibility settings, which makes menus and backgrounds more solid and less blurred. This can make your phone feel less "glassy" and more defined. These settings affect the overall feel of your interface without changing the theme itself.

Frequently Asked Questions

Can I use custom themes from outside the App Store?

No. iOS does not allow installation of themes from outside Apple's ecosystem. You can change wallpapers, icons, and widgets, but the underlying system design stays the same. This is different from Android, where you can install complete third-party themes that change everything.

Will changing to Dark mode drain my battery faster?

No—the opposite is true on newer iPhones. On iPhone 12 and newer with OLED screens, Dark mode uses less battery because dark pixels require less power. On older iPhones with LCD screens, there is no battery difference between Light and Dark mode.

How do I get my lock screen to show different information?

Add widgets to your lock screen during customization. Long-press your lock screen, tap Customize, then tap the area above or below the time to add widgets. You can show weather, calendar events, reminders, battery percentage, or activity rings depending on which apps you have installed.

Can I have different home screen layouts on different pages?

Yes. Each home screen page can have a different arrangement of apps and folders. You can also hide entire pages so they do not appear when you swipe. This lets you create a minimal first page and keep less-used apps on hidden pages or in the App Library.

What happens to my theme if I update iOS?

Your theme settings stay the same after an iOS update. Your wallpapers, lock screen customizations, and app arrangements are preserved. Apple occasionally adds new wallpaper collections and customization options in major updates, but your existing setup will not change.
