You’re staring at your iPhone and something is just… off. Maybe the Wi-Fi keeps dropping for no reason, or your brightness slider has developed a mind of its own. Perhaps you messed around with some accessibility features and now the screen looks like a neon nightmare. We’ve all been there. You want to fix it, but you definitely don't want to wipe your photos of that overpriced brunch or lose your three years of text threads.
That’s where the "Restore All Settings" option comes in. It’s the middle child of iPhone troubleshooting. It isn't as wimpy as a simple restart, but it’s nowhere near as destructive as a factory reset.
Honestly, it’s one of the most misunderstood buttons in the iOS "Transfer or Reset" menu. People see the word "Reset" and they panic. They think their digital life is about to vanish into the iCloud ether. But it’s actually a surgical tool. When you restore all settings on iPhone, you’re basically telling the operating system to forget your preferences and go back to the way it felt when you first slid it out of that sleek white box.

What Actually Happens When You Hit the Button?
Let's get the scary part out of the way first. You aren't losing your apps. Your music stays. Your contacts are safe.
So, what goes away? Think of it as a digital house cleaning. Every Wi-Fi password you’ve ever typed in? Gone. Those Bluetooth headphones you spent twenty minutes pairing? You’ll have to pair them again. Your Apple Pay cards? Removed for security. Your alarm clock settings? Reset. (Seriously, don't forget to set your alarm for work after doing this, or you’re going to have a very awkward conversation with your boss tomorrow morning.)
Apple’s official documentation notes that this process resets everything from privacy settings and location services to keyboard dictionaries and network configurations. It is the nuclear option for software glitches that aren't tied to your actual data. If your phone is lagging or a specific system feature is acting buggy, this is usually the fix that Genius Bar employees try before they resort to the "wipe it and start over" speech.
The Network Headache
The biggest pain point is the network. Because this process flushes your network settings, your phone will forget every "Home," "Office," and "Starbucks" Wi-Fi network it knows. If you don’t know your home Wi-Fi password by heart, go find that dusty router and take a photo of the sticker on the back before you start. You'll also lose any VPN configurations or manual DNS settings you might have painstakingly set up for work or privacy.
Privacy and Permissions
Every time an app asks, "Can I track your location?" or "Can I access your photos?" that preference is stored in your settings. Restoring everything resets these to the default. For the next two days, your phone is going to be very "chatty." Every app you open will ask for permissions again. It’s annoying, sure, but it’s also a great opportunity to say "No" to those apps that have been tracking you for no good reason.
When Should You Actually Do This?
Don't just do this for fun. It’s a chore to set your phone back up. But there are specific scenarios where it’s the only logical move.
If your battery is draining at a ridiculous rate—like 20% in an hour while sitting in your pocket—it might be a rogue background setting or a corrupted system preference. Sometimes a software update leaves behind "ghost" settings that conflict with the new OS. It happens. Technology is messy.
Another huge red flag is persistent connectivity issues. If your 5G is crawling or your Bluetooth keeps disconnecting from your car, and you've already tried "Reset Network Settings," then a full settings restore is the next logical step. It clears out deeper system-level conflicts that a simple network reset misses.
A Quick Word on the "Ghost in the Machine"
Have you ever had your iPhone screen stay black during a call? Or maybe the "Raise to Wake" feature just stopped working? These are often caused by corrupted preference files. You can’t see these files. You can’t delete them individually. The only way to flush them out is to restore all settings on iPhone and let the system rebuild those files from scratch.
The Step-by-Step (Without the Fluff)
Alright, let's get into the "how-to." It’s buried deeper than it used to be in older versions of iOS, probably to stop people from accidentally clicking it.
- Open Settings.
- Tap General.
- Scroll all the way to the bottom. Like, all the way.
- Tap Transfer or Reset iPhone. (Don’t worry, you aren't transferring anything yet).
- Tap Reset at the bottom. A menu will pop up.
- Choose Reset All Settings.
At this point, your iPhone will ask for your passcode. Then it will ask again. It wants to be really, really sure you know what you’re doing. Once you confirm, the screen will go black, the Apple logo will appear, and a progress bar will crawl across the screen. This usually takes between two to five minutes.
When it reboots, it will look like your old phone, but the wallpaper might be back to the default, and you'll need to re-enable things like "Dark Mode" if you prefer that look.
Myths and Misconceptions
I’ve seen people on forums claim that this deletes your eSim. It doesn't. Your cellular plan is safe. Others think it logs you out of iCloud. It doesn't do that either, though you might need to re-verify your Apple ID password for certain services like iMessage or FaceTime.
There's also a common fear that this will "slow down" the phone. Actually, it’s usually the opposite. By removing cluttered cache files and corrupted preferences, your phone often feels snappier. It’s like clearing the "junk" out of the RAM of the operating system's brain.
The iCloud Backup Safety Net
Even though this process doesn't touch your data, I’m a paranoid tech expert. Always, and I mean always, run a manual iCloud backup before doing any kind of reset. Go to Settings > [Your Name] > iCloud > iCloud Backup > Back Up Now. If something goes catastrophically wrong—like your phone dying mid-reset—you’ll want that safety net.
The "Aftercare" Checklist
Once the apple logo disappears and you’re back at your lock screen, the work begins. You’re going to feel like your phone is broken for a second because it won't connect to the internet.
First, reconnect to your Wi-Fi.
Second, go into your Bluetooth settings and repair your watch or earbuds.
Third, re-add your credit cards to the Wallet app. Apple requires this because the secure enclave wipes that sensitive data during a settings reset for your protection.
Finally, check your "Display & Brightness" and "Sounds & Haptics." Your custom ringtones will still be there, but you might need to re-select them as your default.
Actionable Next Steps
If you’re currently dealing with a glitchy iPhone, don't jump straight to a factory wipe. Start with a simple "Reset Network Settings" if the issue is just internet-related. If the problem is systemic—lag, battery drain, or weird UI bugs—then proceed to restore all settings on iPhone.
- Document your current setup: Take screenshots of your Home Screen layout if you use custom icons or widgets, as these can sometimes shift.
- Verify your passwords: Make sure you have your Wi-Fi and Apple ID passwords handy.
- Trigger the reset: Follow the path: Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.
- Audit your privacy: As apps ask for permissions over the next few hours, take a moment to decide if they really need your data.
By taking these steps, you effectively "refresh" your device's soul without losing its "memories." It’s the most efficient way to solve 90% of iOS software issues without the nightmare of a total data restoration.
