A reset on iPhone does not delete everything by default — it depends which reset you choose

When you reset an iPhone, you have several options, and they delete different amounts of data. A soft reset (force restart) closes all apps and clears temporary files but leaves your photos, messages, contacts, and settings untouched. A factory reset (erase all content and settings) removes everything — apps, photos, messages, contacts, settings, and passwords — and returns the phone to the state it was in when it left the factory. Most people who say "reset my iPhone" mean one or the other, but the outcome is completely different.

The confusion happens because the word "reset" covers multiple actions. Your iPhone's Settings app offers at least four distinct reset options, each with its own scope. Knowing which one you are about to do is the difference between solving a frozen app and accidentally erasing years of photos.

Key Takeaways

  • A soft reset (force restart) closes all running apps and clears temporary memory without deleting any of your data or settings.
  • A factory reset erases everything on your phone — photos, messages, contacts, apps, and settings — and cannot be undone unless you have a backup.
  • Before any reset, back up your phone to iCloud or a computer using Finder or iTunes, because some resets are permanent.
  • You can find reset options in Settings > General > Transfer or Reset, and each option clearly states what it will erase.
  • If your phone is frozen or slow, try a soft reset first — it solves most problems without touching your data.

The four types of iPhone reset and what each one does

The soft reset is the gentlest option. To force restart your iPhone, you press and release the volume up button, then press and release the volume down button, then press and hold the side button until the "slide to power off" screen appears. Hold it a few more seconds until you see the Apple logo. This closes every app, clears the phone's temporary memory, and restarts iOS. Your photos, messages, contacts, and all settings stay exactly as they were. A soft reset takes about two minutes and solves most freezing, crashing, or slowness problems.

The second option is a network settings reset. Go to Settings > General > Transfer or Reset > Reset > Reset Network Settings. This erases your saved Wi-Fi passwords, Bluetooth pairings, and cellular settings, then restarts the phone. Your data stays. This is useful if your phone cannot connect to Wi-Fi or Bluetooth, or if your cellular connection is broken. You will need to re-enter Wi-Fi passwords afterward.

The third option is a keyboard and dictionary reset. Settings > General > Transfer or Reset > Reset > Reset Keyboard Dictionary clears the custom words you have taught your keyboard and resets autocorrect to factory defaults. Nothing else is touched. This is rarely needed but can fix a keyboard that is autocorrecting incorrectly.

The fourth option is the factory reset, also called "erase all content and settings." Go to Settings > General > Transfer or Reset > Erase All Content and Settings. This removes everything — every photo, message, contact, app, setting, and password — and returns the phone to the exact state it was in when it left Apple's factory. This action cannot be undone. Once you confirm, the phone begins erasing and will take 10 to 30 minutes. When it finishes, you will see the setup screen as if you just unboxed a new phone.

When you actually need a factory reset

A factory reset is rarely necessary. Most problems — freezing, crashing, slow performance, Wi-Fi issues, battery drain — are solved by a soft reset or a network settings reset. A factory reset is useful in a few specific situations: you are selling or giving away the phone and want to erase all your data before handing it over; you are experiencing severe, persistent software problems that survive multiple soft resets and a network reset; or you are setting up the phone as new after a major iOS update failed.

If you are troubleshooting a problem, try a soft reset first. If that does not work, try a network settings reset. Only move to a factory reset if both of those have failed and the problem is severe enough to justify erasing everything.

How to back up before any reset

Before you do any reset except a soft reset, back up your phone. A soft reset does not erase anything, so a backup is not necessary. But for a network settings reset, keyboard reset, or factory reset, a backup protects your data in case something goes wrong.

The easiest method is iCloud backup. Go to Settings > [Your Name] > iCloud > iCloud Backup and turn it on. Your phone will back up automatically when it is plugged in, connected to Wi-Fi, and locked. You can also tap "Back Up Now" to start when ready. The backup includes photos, messages, contacts, app data, settings, and passwords. iCloud offers 5 GB free; if your phone uses more, you pay for additional storage.

The second method is a computer backup. On a Mac with macOS Catalina or later, open Finder, plug in your iPhone, click the iPhone in the sidebar, and click "Back Up Now." On a Windows PC or older Mac, use iTunes instead. A computer backup is encrypted and includes everything on your phone. It takes longer than iCloud but does not count against your iCloud storage limit.

What happens after a factory reset

After a factory reset completes, your iPhone shows the setup screen — the same screen you saw when you first turned it on. You can set it up as a new phone, or you can restore from your backup. If you restore from iCloud, sign in with your Apple ID and choose the backup you want. The phone will read your photos, messages, contacts, app data, and settings from iCloud. If you restore from a computer backup, plug in the phone, open Finder or iTunes, and click "Restore Backup." Either way, restoration takes 10 to 30 minutes depending on how much data you have.

If you did not back up before the reset, your data is gone. There is no recovery option. This is why a backup before a factory reset is essential.

The difference between reset and restore

Reset and restore are different actions and people often confuse them. A reset erases data and returns the phone to factory defaults. A restore takes a backup you made earlier and puts that data back onto the phone. You usually reset first, then restore from backup. Reset clears the slate. Restore fills it back in.

If you reset without a backup, you cannot restore. If you restore without resetting first, you are putting old data on top of whatever is already there, which can cause problems. The correct order is: back up, reset, restore from backup.

Frequently Asked Questions

If I force restart my iPhone, will I lose my photos?

No. A force restart (soft reset) does not delete anything. It closes all apps and clears temporary memory, then restarts the phone. Your photos, messages, contacts, and settings remain unchanged. A soft reset is safe to do anytime.

Can I undo a factory reset?

Only if you have a backup. Once you erase all content and settings, the data is gone from the phone. If you backed up to iCloud or a computer beforehand, you can restore from that backup and get your data back. If you did not back up, the data cannot be recovered.

What is the fastest way to fix a slow iPhone?

Start with a soft reset. Press and release volume up, press and release volume down, then hold the side button until you see the Apple logo. This solves most slowness without erasing anything. If that does not work, try a network settings reset. Only do a factory reset if both of those have failed.

Do I need to back up before a soft reset?

No. A soft reset does not erase any data, so a backup is not necessary. You only need to back up before a network settings reset, keyboard reset, or factory reset.

What happens to my apps when I factory reset?

All apps are deleted during a factory reset. When you restore from backup, the apps you had before are reinstalled automatically from the App Store. If an app is no longer available in the App Store, it will not be restored.
