Whether youre a first-time updater or a seasoned Apple user, this tutorial ensures you update safely, efficiently, and with full confidence.

Step-by-Step Guide

Updating your iOS version is a straightforward process, but doing it correctly requires attention to detail. Follow these steps carefully to ensure a smooth, successful update without data loss or unexpected interruptions.

Check Your Current iOS Version

Before initiating any update, its essential to know which version of iOS youre currently running. This helps you understand whether an update is even necessary and what changes you can expect.

To check your current iOS version:

1. Open the Settings app on your iPhone or iPad.
2. Tap General.
3. Select About This Device.
4. Look for the entry labeled Software Version. This will display your current iOS version (e.g., iOS 16.7.2).

If your version is older than the latest public release, an update is available. Apple typically releases major updates in the fall (e.g., iOS 17) and minor security updates throughout the year. Always compare your version to the latest public release listed on Apples official support site.

Ensure Your Device Is Compatible

Not all devices support the latest iOS versions. Apple typically supports iPhones for about five to six years after release. For example, iOS 17 requires an iPhone 8 or later. Older models like the iPhone 6s or iPhone SE (1st generation) are limited to iOS 15 or earlier.

To confirm compatibility:

• Visit Apples official iOS compatibility page.
• Match your device model with the latest supported iOS version.

If your device is no longer supported, you can still use it safely with the last compatible version, but you wont receive future feature updates or security patches. In such cases, consider upgrading your hardware for continued protection and performance.

Backup Your Data

Although iOS updates are generally safe, unexpected issuessuch as power loss during installation or software conflictscan occasionally occur. A backup ensures your photos, messages, contacts, app data, and settings are preserved.

Use one of two backup methods:

iCloud Backup

This method is wireless and convenient:

1. Go to Settings > tap your name at the top > select iCloud.
2. Tap iCloud Backup.
3. Ensure iCloud Backup is turned on.
4. Tap Back Up Now and wait for the process to complete.

Make sure your device is connected to Wi-Fi and plugged into a power source. iCloud backups require sufficient storage space. If youre running low, consider purchasing additional iCloud storage or using a computer-based backup instead.

Computer Backup (Finder or iTunes)

For a more secure, local backup:

1. Connect your device to your Mac or PC using a Lightning or USB-C cable.
2. On macOS Catalina or later, open Finder. On older macOS or Windows, open iTunes.
3. Select your device when it appears in the sidebar.
4. Under the Backups section, choose This Computer.
5. Check Encrypt local backup if you want to preserve Health and Keychain data (recommended).
6. Click Back Up Now and wait for completion.

Computer backups are faster, more reliable, and do not rely on internet connectivity or cloud storage limits. Theyre ideal for users with large media libraries or sensitive data.

Connect to Wi-Fi and Plug In

iOS updates can be several gigabytes in size. Downloading over cellular data may consume your data plan and could fail due to unstable connections. Always use a stable Wi-Fi network.

Additionally, ensure your device has at least 50% battery or is connected to a power source. Apple recommends keeping your device plugged in during the entire update process to prevent interruptions.

Download and Install the Update

Once your device is backed up and connected to power and Wi-Fi, proceed with the update:

1. Open the Settings app.
2. Tap General > Software Update.
3. If an update is available, youll see a description of the new version (e.g., iOS 17.5 Includes security updates and performance improvements).
4. Tap Download and Install.
5. If prompted, enter your passcode.
6. Wait for the download to complete. The progress bar will appear on-screen.
7. Once downloaded, tap Install.
8. Your device will restart automatically. The installation process may take 1030 minutes, depending on your device and the size of the update.

During installation, your device may display a black screen with an Apple logo. Do not interrupt the process by unplugging or pressing buttons. Let it complete fully.

Complete Post-Update Setup

After the update installs, your device will reboot. You may be prompted to:

• Set up Face ID or Touch ID again (rare, but possible after major updates).
• Reconfigure certain app permissions.
• Review new features or privacy settings introduced in the update.

Some apps may need to be updated separately through the App Store to work optimally with the new iOS version. Open the App Store, tap your profile icon, and check for available updates under Available Updates.

Verify the Update Was Successful

To confirm your device is running the latest version:

1. Go to Settings > General > About This Device.
2. Check the Software Version field.
3. Compare it to the latest version listed on Apples website.

If the version number matches the latest release, your update was successful. If not, return to Settings > General > Software Update and try downloading again.

Best Practices

Updating iOS isnt just about clicking Install. Following industry-tested best practices ensures maximum safety, minimal disruption, and long-term device health.

Update During Off-Peak Hours

Apples servers experience high traffic immediately after a new iOS version is released. Waiting 2448 hours after the public release reduces the risk of server-side errors or delayed downloads. Early adopters may encounter bugs that are patched in subsequent point releases (e.g., iOS 17.1.1).

Disable Automatic Updates if You Prefer Control

While iOSs automatic update feature is convenient, it can be problematic if youre in the middle of work, travel, or a critical task. To manage updates manually:

1. Go to Settings > General > Software Update.
2. Tap Automatic Updates.
3. Toggle off Download iOS Updates and Install iOS Updates.

This gives you full control over when updates are downloaded and installed, reducing the chance of unexpected restarts.

Clear Storage Space Before Updating

iOS updates require at least 510 GB of free space to download and install. If your device is nearly full, the update may fail or hang. Free up space by:

• Deleting unused apps and their data.
• Offloading rarely used apps via Settings > General > iPhone Storage > Offload App.
• Deleting old photos and videos (upload to iCloud or a computer first).
• Clearing Safari cache: Settings > Safari > Clear History and Website Data.
• Removing large attachments from Messages: Settings > Messages > Keep Messages > set to 30 days or 1 year.

Use the iPhone Storage section to identify the largest files and apps consuming space.

Update All Apps Before Updating iOS

Some apps are not immediately compatible with new iOS versions. Updating apps beforehand ensures smoother transitions. Open the App Store, tap your profile icon, and update all pending apps before proceeding with the iOS update.

Do Not Skip Minor Updates

Minor updates (e.g., iOS 17.1, iOS 17.2) often contain critical security patches. Many users ignore these, thinking theyre not important. In reality, Apple frequently releases these updates to fix exploits discovered after the major release. Always install them promptly.

Monitor Battery Health After Updates

After a major iOS update, some users report temporary battery drain. This is usually due to system optimization and indexing. Allow 2448 hours for your device to adapt. If battery life remains poor:

• Restart your device.
• Check Settings > Battery > Battery Health to ensure your battery capacity is above 80%.
• Disable background app refresh for non-essential apps.

Test Core Functionality After Update

After updating, verify that essential features work correctly:

• Make a test call or FaceTime.
• Send a text message.
• Open your most-used apps (email, banking, calendar).
• Check Wi-Fi, Bluetooth, and location services.

If any feature behaves abnormally, restart your device. If problems persist, consult Apples support forums or restore from your backup.

Tools and Resources

Several tools and resources are available to help you manage iOS updates efficiently, troubleshoot issues, and stay informed about the latest developments.

Apple Support Website

The official Apple Support: iOS page is your primary source for release notes, compatibility lists, known issues, and step-by-step guides. Always refer here before attempting an update if youre uncertain.

iOS Release Notes

Each iOS update includes detailed release notes outlining:

• New features
• Security fixes

• Exporting data to PC/Mac in readable formats.
• Managing app data and documents.

These tools are especially useful for users who need granular control over their data or who have experienced failed iTunes/Finder backups. Always choose reputable, privacy-focused tools with clear data handling policies.

Network Diagnostics Tools

If your update fails due to Wi-Fi issues, use your routers admin panel to:

• Restart your router.
• Switch to a 5 GHz band for faster downloads.
• Temporarily disable firewalls or parental controls that may block Apples update servers.

Tools like WiFi Analyzer (Android) or NetSpot (Mac/Windows) can help identify interference or weak signal areas.

Apple Configurator 2 (for IT Administrators)

For businesses or schools managing multiple iOS devices, Apple Configurator 2 (free on Mac App Store) allows bulk updates, configuration profiles, and supervised device management without user interaction.

Real Examples

Real-world scenarios illustrate how iOS updates impact users differently and why following proper procedures matters.

Example 1: The Business User Who Missed a Security Patch

A marketing professional used an iPhone 11 running iOS 15.7. She ignored the iOS 16.6 update because she didnt see new features. Two weeks later, her device was targeted by a phishing exploit that had been patched in iOS 16.6. Attackers accessed her corporate email via a malicious link she clicked. Had she updated promptly, the exploit would have been blocked. This highlights that iOS updates arent just about bells and whistlestheyre critical for security.

Example 2: The Parent Who Updated Without Backup

A mother updated her daughters iPad to iOS 17 without backing up. During installation, the device froze and entered recovery mode. She couldnt restore from iCloud because the iPad was locked with a forgotten passcode. She lost 2,000+ photos, school projects, and voice memos. After restoring via Finder, she recovered only the last backupmade six months prior. She now backs up every Sunday and enables automatic iCloud backups.

Example 3: The Developer Testing a New Feature

A mobile app developer wanted to test a new ARKit feature introduced in iOS 17.2. Instead of updating immediately, he waited for the official release notes, confirmed compatibility with his development tools, and updated his test devices after verifying that no known bugs affected his apps core functions. He avoided crashes during client demos by ensuring stability first.

Example 4: The Senior Citizen Who Found iOS 17 Confusing

An 72-year-old user updated to iOS 17 and was overwhelmed by the redesigned Control Center and new Live Activities. She disabled unnecessary features via Settings > Control Center and restored her previous home screen layout. She also enabled Accessibility > Display & Text Size to increase font size. Apples updates can be intimidating, but customization options make them adaptable.

Example 5: The Traveler with Limited Wi-Fi

A frequent traveler updated his iPhone using airport Wi-Fi, which was unstable. The download failed twice, and he nearly used 10 GB of cellular data. He later learned to download updates only on trusted home or hotel networks. He now uses his laptop to download the IPSW file via iTunes and manually installs it via recovery modeavoiding unreliable networks entirely.

FAQs

Can I update iOS without Wi-Fi?

Technically, yesiOS allows downloading updates over cellular data if you enable it in Settings > General > Software Update > Download Over Cellular. However, this is strongly discouraged due to large file sizes (often 46 GB), potential data overages, and unreliable mobile networks. Always use Wi-Fi.

What if my device says Update Failed?

If you see Update Failed, try these steps:

• Restart your device and retry.
• Ensure you have at least 5 GB of free storage.
• Connect to a different Wi-Fi network.
• Use a computer to update via Finder or iTunes.
• If the issue persists, put your device into recovery mode and restore using a computer.

Will updating iOS delete my apps and data?

No. A standard iOS update preserves all your apps, photos, messages, and settings. Only a factory restore (via recovery mode) will erase everything. Always backup before updating, but data loss is extremely rare during normal updates.

Can I downgrade to an older iOS version?

Apple typically stops signing older iOS versions within days of releasing a new one. This means you cannot downgrade unless Apple is still signing the previous version (rare). Once you update, youre locked into the newer version. Plan accordingly.

Why does my battery drain faster after updating?

After a major update, iOS reindexes files, rebuilds caches, and optimizes apps for the new system. This causes temporary battery drain. Allow 2448 hours for the system to stabilize. If drain continues, reset settings via Settings > General > Transfer or Reset iPhone > Reset All Settings (this wont delete data).

Do I need to update every time Apple releases a new version?

Youre not required to update immediately, but Apple strongly recommends installing all updatesespecially security patches. Major updates (iOS 16 ? iOS 17) offer new features, while minor updates (iOS 17.1 ? iOS 17.2) fix bugs and close security holes. Delaying updates increases your exposure to cyber threats.

What if my device is too old to update?

If your device cant run the latest iOS, its still safe to use with the last supported version. However, you wont receive new features or security patches. Consider upgrading to a newer model for better performance, longer battery life, and ongoing support. Apple devices typically last 45 years before performance declines significantly.

Can I update an iPad running iPadOS the same way?

Yes. iPadOS is built on the same foundation as iOS. The update process is identical: Settings > General > Software Update. All best practices, backup methods, and troubleshooting steps apply.

Why is the update taking so long?

Download and installation times depend on:

• Internet speed
• Device storage speed
• Size of the update (major updates are larger)
• Background processes

A 5 GB update on a fast Wi-Fi network typically takes 1020 minutes to download and 1530 minutes to install. Be patient. Do not interrupt.

Will my Apple Watch or AirPods be affected by an iOS update?

No. iOS updates do not directly affect paired Apple Watch or AirPods. However, you may receive separate software updates for these devices via the Watch or Find My app. Ensure theyre charged and connected to your iPhone during the update process.
