In a world driven by technology, staying updated is more than a suggestion—it’s a necessity. Whether you’re hoping to improve your phone’s performance, gain access to the latest features, or ensure you’re protected with the most recent security patches, keeping your iPhone up to date is one of the easiest and most important things you can do.
But let’s be honest—many iPhone users delay updates. Sometimes it’s because they’re unsure how to do it, or maybe they fear the process will erase their data, slow down their phone, or take forever. If you’ve ever felt that way, you’re not alone.
This in-depth guide will walk you through how to update your iPhone, why it matters, and what to do before, during, and after an update. Whether you’re brand new to iOS or a seasoned Apple user, this guide is for you.
Why You Should Keep Your iPhone Updated
Before we dive into the how-to, let’s talk about the why. Updating your iPhone isn’t just about getting new emojis or flashy features. There’s a lot more happening behind the scenes.
1. Security Enhancements
Apple regularly releases patches to fix vulnerabilities that hackers could exploit. Updates often include crucial security improvements to keep your data safe.
2. New Features and Improvements
With each new iOS version, Apple introduces tools to make your iPhone smarter and more efficient. Think redesigned widgets, app improvements, privacy enhancements, and more.
3. Bug Fixes
If your phone is freezing, crashing, or behaving oddly, there’s a good chance that an update can resolve those issues.
4. App Compatibility
Many third-party apps require the latest iOS versions to run properly. Updating your system ensures that your apps stay compatible and function well.
Types of iPhone Updates
Not all updates are the same. Apple typically releases three types:
- Major Updates (e.g., iOS 17): Big releases with feature overhauls, typically launched annually.
- Minor Updates (e.g., iOS 17.1.1): Smaller patches that fix bugs or security issues.
- Security Updates: Special updates focused only on security, which might roll out even if you’re not on the latest iOS.
Before You Update: What You Should Do First
Though updating is generally safe, a little preparation goes a long way. Here’s how to get ready:
✅ 1. Backup Your iPhone
Even though updates don’t usually erase data, it’s best to back up your iPhone just in case something goes wrong.
You can back up using:
- iCloud: Settings > [Your Name] > iCloud > iCloud Backup > Back Up Now.
- Computer (Mac or PC): Connect your iPhone with a cable, open Finder (Mac) or iTunes (PC), and select “Back Up Now.”
✅ 2. Charge Your Device
Make sure your iPhone has at least 50% battery or is plugged into a charger. If your phone dies during an update, it could lead to issues.
✅ 3. Connect to Wi-Fi
Updates are large and can eat up mobile data. Always use a reliable Wi-Fi connection.
✅ 4. Free Up Storage
iOS updates can range from a few hundred megabytes to several gigabytes. Check your storage:
- Go to Settings > General > iPhone Storage and delete unused apps, photos, or videos if necessary.
How to Update Your iPhone (Over-the-Air Method)
This is the most common and easiest method—right from your iPhone, no cables required.
Step-by-Step:
- Open the Settings App.
- Scroll down and tap General.
- Tap Software Update.
- Your iPhone will check for updates. If one is available, you’ll see a description and an option to Download and Install.
- Tap Download and Install. You may need to enter your passcode.
- Agree to the terms and conditions.
- Your phone will begin downloading the update. Once it’s ready, it will restart and install the update.
The update process may take anywhere from 15 minutes to an hour, depending on your internet speed and the size of the update.
How to Update Using a Computer (Manual Method)
If you prefer using a computer or can’t update over Wi-Fi, this method works just as well.
For macOS Catalina or Later:
- Connect your iPhone to your Mac using a USB cable.
- Open Finder.
- Select your iPhone under “Locations.”
- Click General, then click Check for Update.
- Click Download and Update.
For macOS Mojave or Windows (Using iTunes):
- Connect your iPhone via USB.
- Open iTunes.
- Click the Device icon.
- Under the Summary tab, click Check for Update.
- Click Download and Update.
How to Enable Automatic Updates
If you’d rather not deal with updates manually, your iPhone can do it for you while you sleep.
To Turn On Automatic Updates:
- Go to Settings > General > Software Update.
- Tap Automatic Updates.
- Turn on both Download iOS Updates and Install iOS Updates.
Your iPhone will install updates overnight, typically while charging and connected to Wi-Fi.
What to Do If the Update Fails
While rare, updates can sometimes fail. If your update gets stuck, here are a few tips:
✅ 1. Force Restart Your iPhone
- For iPhone 8 or later: Press and quickly release the Volume Up, then Volume Down, then press and hold the Side button until the Apple logo appears.
✅ 2. Check Internet Connection
Make sure you’re on a stable Wi-Fi network. Poor connectivity can interrupt the download or install process.
✅ 3. Clear Storage
If your iPhone says it can’t install the update due to lack of space, go to Settings > iPhone Storage and clear out some files.
✅ 4. Try Updating via Computer
If over-the-air fails, connect your phone to a computer and update via Finder or iTunes as outlined earlier.
✅ 5. Use Recovery Mode (Last Resort)
If your phone is stuck on the Apple logo or a spinning wheel, you may need to restore it using Recovery Mode. This erases the device, so make sure you have a backup.
After the Update: What You Should Do
Once your iPhone restarts after the update, you’re not quite done. Here are a few tips for post-update care:
✅ 1. Check for App Updates
Some apps may require updates to work properly with the new iOS. Open the App Store, tap your profile icon, and scroll down to update your apps.
✅ 2. Revisit Settings
Major iOS updates often add new settings or change existing ones. Spend a few minutes exploring Settings to customize the new features.
✅ 3. Explore What’s New
Head to Settings > General > About > iOS Version, or look at the iOS release notes in Settings to see what features were added.
