Skipping software updates leaves your phone exposed to security threats and performance lags. Keeping your iPhone current protects your personal data, introduces critical bug fixes, and unlocks new tools. You don't need to wait for automatic overnight prompts or guess if your device is ready.
Let's dive right into how software updates impact your device, the exact preparation steps you need to follow, and how to troubleshoot common download stalls.
Why You Should Never Ignore an iOS Update
Many users ignore update notifications because they fear bugs or losing storage space. However, staying on an outdated operating system creates distinct risks.
Apple continuously issues patches for discovered security vulnerabilities. When hackers discover an exploit, they target older operating systems because those flaws remain unpatched. Updating your device closes these security windows immediately.
Beyond security, your daily apps rely on modern application programming interfaces. As developers update apps for newer software standards, running an outdated iOS version causes app crashes, battery drain, and unexpected freezes.
- Security patches: Block active cyber threats and safeguard your private data.
- Performance stabilization: Fix memory leaks and background processing loops that cause overheating.
- App compatibility: Ensure banking, messaging, and productivity apps run their latest stable versions.
Essential Preparation Steps Before You Begin
Jumping straight into an update without preparation can result in failed installations or data loss. Take these three precautions before tapping the install button.
First, secure a reliable backup. While updates rarely delete user data, unexpected hardware glitches or power losses can corrupt your system storage. Go to your Apple ID settings, select iCloud, tap iCloud Backup, and select Back Up Now. Alternatively, plug your phone into a computer and create an archived backup via Finder or iTunes.
Second, check your available storage. Major software upgrades often require several gigabytes of free space to unpack and install temporary installation files. Navigate to Settings, tap General, and select iPhone Storage. If you're running low, offload unused apps or temporarily transfer large video files to cloud storage.
Third, verify your power and network status. Your device must be connected to a stable Wi-Fi network and maintain a battery charge above fifty percent—or remain plugged into a wall charger.
How to Update Your iPhone Step by Step
You can update your device directly over-the-air or use a computer if your wireless connection is unstable.
Method 1: Over-the-Air Update via Wi-Fi
This is the fastest method for most users and requires nothing more than your device and a Wi-Fi connection.
- Open the Settings app on your iPhone.
- Tap General, then tap Software Update.
- Review the available software version and tap Download and Install.
- Enter your device passcode when prompted.
- Agree to the terms and conditions, and let the progress bar finish while your phone restarts.
Method 2: Manual Update Using a Mac or PC
If your phone lacks sufficient storage space for an over-the-air download, updating through a computer bypasses local unpacking limits.
- Connect your iPhone to your computer using a compatible cable.
- Open Finder on modern macOS versions, or iTunes on Windows and older Macs.
- Locate and select your device in the sidebar menu.
- Click General or Summary, then click Check for Update.
- Click Update to download and install the package directly through your computer.

Fixing Common Update Stalls and Errors
Even with proper preparation, updates occasionally freeze during the downloading or verifying stage. Knowing how to react saves you from panic.
If your download freezes on "Estimating Time Remaining," your Wi-Fi network likely dropped packets. Toggle your Wi-Fi off and back on via the Control Center, or restart your router.
If the update file is corrupted, your phone will stay stuck on the verification screen. To clear a stuck file, go to Settings, tap General, and open iPhone Storage. Locate the iOS update file in the list, tap it, and select Delete Update. Return to Software Update to download a fresh, uncorrupted copy.
Frequently Asked Questions
Will I lose my photos or messages when I update?
No. Standard software updates leave your personal photos, messages, app data, and custom settings completely untouched. However, running a manual backup beforehand is always recommended just in case an unforeseen hardware error occurs.
Why does my phone say my storage is full during an update?
Your iPhone needs temporary room to download, extract, and apply the software package before cleaning up after itself. If you see a storage warning, temporarily delete a large game or offload unused media files until the installation finishes.
Should I install major iOS updates on day one?
If the update includes critical zero-day security patches, install it immediately. If it's a major annual platform redesign, many users prefer waiting for the first minor point release (such as a .1 update) to ensure third-party app compatibility has stabilized.
Can I downgrade my iOS if I don't like the update?
Apple stops signing older software versions shortly after releasing a new update. Once the signing window closes, you cannot officially downgrade your operating system back to an older version.
