iOS 18.5 vs iOS 18.4: Which Update Should You Choose?

Apple’s iOS updates bring exciting new features, bug fixes, and improvements to your iPhone. But with so many updates, it can be confusing to decide which one is right for you. In this guide, we’ll compare iOS 18.4 (the latest public update) and iOS 18.5 Beta 4 (a test version for developers).

Whether you’re a student, parent, or just love your iPhone, this guide will help you understand what’s new, what’s fixed, and which update you should install. Let’s get started!

What’s New in iOS 18.4?

iOS 18.4 is a free update for all compatible iPhones (iPhone XR and newer). It includes over 60 changes, from fun emojis to smarter notifications. Here are the top features you need to know:

1. Apple Intelligence Upgrades

Apple Intelligence is a set of smart tools that help your iPhone understand you better. In iOS 18.4, it gets even smarter:

  • Priority Notifications:
    • Your iPhone now sorts notifications by importance. For example, a text from your mom might show up at the top of your Lock Screen, while a game alert stays lower.
    • How to use it: Go to Settings > Notifications > Prioritize Notifications. You can turn it on/off or block specific apps.
  • Visual Intelligence:
    • Point your camera at anything (like a plant or sign), and your iPhone will explain what you’re seeing.
    • How to use it: Open the Control Center and tap the eye icon (or press the Action Button on iPhone 15 Pro/Max).
  • Image Playground:
    • Create fun artwork using AI. The new “Sketch” style turns your photos into pencil drawings.
    • How to use it: Open the Image Playground app, choose a photo, and select “Sketch.”

2. Control Center Improvements

The Control Center (the menu that pops up when you swipe down) got some cool upgrades:

  • Ambient Music:
    • Play relaxing sounds like rainstorms or campfires to help you focus or sleep.
    • How to use it: Swipe down to open the Control Center, tap the music note icon, and pick a mood (Sleep, Chill, etc.).
  • Real-Time Signal Bars:
    • The Wi-Fi and cellular icons now match your actual connection strength. No more guessing if you have good service!

3. New Emojis and Design Tweaks

  • 7 New Emojis:
    • 🥱 Tired Face
    • 🖐️ Fingerprint
    • 🧹 Shovel
    • And more!
  • Brighter Privacy Dots:
    • A small orange dot means your microphone is active. A green dot means your camera is on. These dots are now easier to see.

4. Apps and Features

  • Apple News+ Food:
    • Cook recipes with step-by-step guides. It works like Apple Music lyrics, showing instructions as you cook.
    • Try this: Search for “chocolate chip cookies” in Apple News and follow the recipe.
  • Podcasts Widgets:
    • Add a widget to your Home Screen to see new episodes of your favorite shows.
  • Home App:
    • Control robot vacuums that work with Apple Home. Yes, your iPhone can now clean your room!

What’s New in iOS 18.5 Beta 4?

iOS 18.5 is still in beta testing, meaning it’s not finished yet. Beta 4 gives us a sneak peek at what’s coming. Here’s what’s new:

1. Small But Useful Changes

  • Apple Care Updates:
    • See detailed warranty info for all your Apple devices. For example, it now says “iPhone 16 Pro Max” instead of just “iPhone 16.”
  • New Wallpapers:
    • Two abstract wallpapers are coming soon. They have names like “Innumerable Dark and Light Dots” and “Crystalline Bubbles.”
  • CarPlay Fixes:
    • Fixed issues where music wouldn’t play or the screen froze.

2. Behind-the-Scenes Tweaks

  • Analytics Improvements:
    • Apple collects data to make features like Image Playground and Siri work better.
  • “Flying Unicorn” Flag:
    • A hidden feature for Find My. We don’t know what it does yet, but it might help track lost devices.

3. Known Issues

  • Signal Bars Glitch:
    • The cellular toggle in the Control Center sometimes shows the wrong bars.
  • No “Recently Deleted” Buttons:
    • The Photos app still lacks buttons to recover or delete all photos at once.
