You’re staring at that little red badge on your Settings icon. It’s annoying, right? You know you need to deal with it, but there’s always that nagging fear that your photos will vanish or your phone will turn into an expensive brick. Honestly, learning how to update my iPhone shouldn't feel like a gamble. It’s basically just maintenance, like changing the oil in a car, but for some reason, Apple makes the "Storage Almost Full" pop-up feel like a personal attack.
Software updates are actually pretty cool because they fix the stuff developers messed up in the last version. They patch security holes that hackers love to exploit. If you haven't updated in a while, your phone is basically walking around with its front door unlocked.
Before You Even Touch That "Download and Install" Button
Stop. Don't do it yet.
If you just hit update while you're sitting on a bus with 12% battery, you're asking for a headache. The absolute first thing you have to do is back up your data. Use iCloud or plug the thing into a Mac or PC. Seriously. I’ve seen people lose five years of baby photos because a random power flicker killed their Wi-Fi mid-update. It happens.
Check your storage too. Go to Settings > General > iPhone Storage. If you have less than 5GB or 6GB of free space, the update will probably fail or just hang there forever. You might need to offload some apps you haven't touched since 2022 or delete those 4K videos of a concert you'll never watch again.
The Standard Way: Over-the-Air (OTA) Updates
This is what 99% of people do. It’s the easiest way to figure out how to update my iPhone without needing any cables.
- Plug your phone into a charger. Updates eat battery life like crazy.
- Connect to a solid Wi-Fi network. Don't try this on cellular data unless you have a massive 5G plan and a lot of patience.
- Open Settings.
- Tap General.
- Hit Software Update.
Your iPhone will talk to Apple's servers. If an update is available, you’ll see a description of what’s in it. Tap Download and Install. Sometimes it asks for your passcode. Sometimes it asks if you want to use cellular data if the Wi-Fi is slow. Just follow the prompts. The screen will go black, an Apple logo will appear with a progress bar, and you’ll have to find something else to do for twenty minutes.
Why Does It Take So Long?
Sometimes the "Preparing Update" phase feels like it lasts an eternity. That’s because your phone isn't just downloading a file; it’s verifying the integrity of the software and unpacking it. If you’re jumping from a very old version of iOS to the newest one, the file size can be massive—sometimes over 5GB.

I remember when iOS 18 launched. Everyone tried to download it at the exact same time. Apple’s servers basically melted. If a big update just came out today, maybe wait 24 hours. Let the rest of the world find the bugs first.
Using a Computer When Everything Else Fails
If your iPhone is being stubborn or you don’t have enough space for an OTA update, use a computer. On a Mac with macOS Catalina or later, you use Finder. On an older Mac or a Windows PC, you use iTunes.
Connect your iPhone with a Lightning or USB-C cable. Open Finder or iTunes. Locate your device in the sidebar. Click Check for Update. This method is actually "cleaner" because the computer downloads the entire firmware package and pushes it to the phone, which can sometimes fix weird glitches that a standard update won't touch. It’s a bit old-school, but it works when the "Settings" app keeps crashing.
What About Automatic Updates?
You can actually tell your iPhone to handle this while you’re asleep. In the Software Update menu, there’s a section for Automatic Updates. You can toggle on "Download iOS Updates" and "Install iOS Updates."
The phone will wait until it’s charging, connected to Wi-Fi, and you aren't using it (usually around 2:00 AM or 3:00 AM). It sounds perfect, but sometimes it doesn't trigger if your battery is too low or your Wi-Fi is spotty. I usually keep "Download" on but "Install" off. I like to know exactly when my phone is going to be out of commission for a half-hour.
Troubleshooting the "Unable to Verify Update" Error
This is the boss fight of iPhone updates. You download the whole thing, and then a box pops up saying it can't be verified because you aren't connected to the internet—even though you clearly are.
Usually, this happens because the download got corrupted. Go to Settings > General > iPhone Storage, find the iOS update file in the list of apps, tap it, and delete it. Then go back to the Software Update menu and start over. It’s annoying, but a fresh download fixes this 9 times out of 10.
The Beta Trap
Occasionally, you'll see an option for "Beta Updates." Unless you are a developer or someone who doesn't mind their phone crashing during a phone call, stay away from these. Betas are unfinished. They're buggy. They drain your battery. Stick to the "Public" releases unless you have a spare phone you don't mind messing up.
Actionable Steps to Take Right Now
- Audit your photos: Delete the screenshots you don't need to clear up space for the download.
- Plug in: Never start an update with less than 50% battery, even if you are plugged in.
- Check your Backup: Go to Settings > [Your Name] > iCloud > iCloud Backup and make sure it says "Last successful backup" was today.
- Be patient: If the progress bar hasn't moved in ten minutes, it's probably still working. Only force restart if it’s been stuck for over an hour.
Updating isn't just about getting new emojis or a different font on your lock screen. It's about keeping your digital life secure. Now that you know how to update my iPhone the right way, just get it over with. Your phone will thank you by not getting hacked or lagging every time you open Instagram.

Specific Fixes for Common Problems
If you see a "Searching for Update" wheel that spins forever, try toggling Airplane Mode on and off. Sometimes the network handshake just gets stuck. Another weird trick is changing your DNS settings to Google's (8.8.8.8) if your ISP is having trouble routing to Apple's update servers.
Most people worry about their "bank apps" or "work email" breaking. Apple is generally very good about "backward compatibility," meaning your apps should work fine after an update. However, if you use a very niche app for a specific job, check the app's website first to ensure they've cleared it for the latest iOS version.
Final Verification
Once the update finishes and the phone restarts, go back to Settings > General > About. Look at the "iOS Version." If the number matches what you were trying to install, you’re golden. You might have to go through a few "Welcome to iPhone" screens and re-enter your Apple ID password, but that’s totally normal. Just take it slow and don't skip the security prompts.
