Every iPhone user runs into a frozen app, an unresponsive screen, or a device that simply feels sluggish. Knowing exactly which reset method to use — and when — is the difference between a two-minute fix and unnecessary panic. This guide covers every restart and reset option available on iPhone, from a basic soft restart to a full factory wipe, with exact steps for current models running iOS 18.
The three core methods are a soft restart (normal power cycle), a force restart (hard reset that bypasses the screen), and a factory reset (complete data wipe). Each serves a distinct purpose. Picking the wrong one wastes time; understanding all three puts complete control back in the user’s hands.
Soft Restart: The First Troubleshooting Step
A soft restart is a controlled shutdown and reboot. It clears temporary memory, closes background processes, and gives iOS a clean slate — without touching a single file, app, photo, or setting on the device. This is the correct first response to app crashes, laggy performance, connectivity drops, and minor screen glitches.
On an iPhone with Face ID (iPhone X and later), press and hold the Side button and either Volume button simultaneously until the power-off slider appears. Drag the slider, wait for the screen to go black, then press the Side button again until the Apple logo appears. On older models with a Home button (iPhone SE 2nd/3rd gen and earlier), press and hold the Top or Side button until the slider appears, drag it off, then hold the Side button to restart.
The entire process takes under two minutes. No data is lost. No settings change. The device simply refreshes its operating state. For heavy users running multiple productivity apps, streaming services, or communication tools simultaneously, a weekly soft restart prevents memory buildup and keeps performance consistent.
When a Soft Restart Solves the Problem
Most everyday iPhone problems respond immediately to a soft restart. Bluetooth not connecting to headphones or a car system is one of the most common complaints — and a restart clears the Bluetooth cache state without requiring a full unpairing. Wi-Fi dropping in areas with strong signal is another case where a restart resets the network stack more effectively than toggling airplane mode.
App crashes that repeat on every launch are often a memory issue rather than a broken app. A soft restart clears RAM and allows the app to load cleanly. Battery drain spikes — where the phone goes from 80% to 40% unusually fast — can also be caused by a runaway background process that a restart terminates. For storage space issues compounding the slowdown, addressing both storage and restart cycles together produces the best results.
Older models benefit from restarts more frequently than newer ones. An iPhone 12 running a large number of apps keeps more processes active than the hardware was designed for under aggressive multitasking. A soft restart once every few days maintains the kind of performance those models delivered when new.
Force Restart (Hard Reset): For Frozen and Unresponsive iPhones
A force restart interrupts the operating system at the hardware level, cutting power to all processes and forcing an immediate reboot. It does not erase data. Every file, app, setting, and credential on the device remains completely intact. The only potential loss is unsaved work in open apps — anything already saved to storage is untouched.
This method is specifically for situations where the screen is frozen, the device won’t respond to any touch, or the iPhone is stuck on the Apple logo during startup. A soft restart is impossible when the screen doesn’t respond, making the button-based force restart the only option that doesn’t require screen interaction.
For iPhone 8, iPhone X, and all later models (including the entire iPhone 15 and 16 series), the sequence is: press and quickly release Volume Up, press and quickly release Volume Down, then press and hold the Side button until the Apple logo appears — typically 10 to 15 seconds. Release the button the moment the logo appears.
For iPhone 7 and 7 Plus, press and hold Volume Down and the Sleep/Wake button simultaneously for 10 seconds until the Apple logo appears.
For iPhone 6s, SE (1st generation), and older models with a Home button, press and hold both the Home button and the Sleep/Wake button simultaneously for 10 seconds until the Apple logo appears.
Common Situations That Require a Force Restart
An iPhone stuck on the Apple logo after an iOS update is one of the clearest signals that a force restart is needed. The update process can stall during the final boot phase, leaving the device in a loop the screen cannot break out of. A force restart interrupts that loop and allows the system to boot cleanly. If the logo reappears and the device boots normally, no further action is needed.
A completely black, unresponsive screen — sometimes called a “black screen of death” — often resolves with a force restart. This happens when iOS crashes at a deeper level than the display layer, making the screen appear dead when the device itself is still powered. A force restart brings it back without data loss.
Devices looping endlessly between startup screens, getting stuck mid-animation, or freezing during a phone call also respond well to this method. The screen rotation and display issues that sometimes accompany a software crash are typically resolved once the device reboots successfully.
Factory Reset: Erase All Content and Settings
A factory reset returns the iPhone to the exact state it was in when it left the factory — a clean iOS installation with no user data, apps, accounts, or settings. This is the most drastic action available and should only be taken after backing up the device, signing out of Apple ID, and understanding that the process is irreversible without a restore from backup.
There are three primary scenarios where a factory reset is appropriate. The first is preparing the device for sale or transfer — resetting ensures no personal data reaches the next owner and disables Activation Lock so the new owner can set it up with their own Apple ID. The second is resolving persistent software problems that survive multiple force restarts and iOS reinstalls. The third is starting completely fresh after the phone has accumulated years of app conflicts, corrupted data, or storage clutter that individual troubleshooting cannot untangle.
Back up to iCloud or a computer via Finder (Mac) or the Apple Devices app (Windows) before proceeding. After the reset, restoring from that backup returns all photos, messages, app data, and settings exactly as they were.
How to Factory Reset iPhone Through Settings
This method works when the iPhone is functional and the screen responds normally. Open the Settings app, tap General, scroll to the bottom, and tap Transfer or Reset iPhone. Tap Erase All Content and Settings. The device will ask for the screen passcode and Apple ID password — both are required to disable Find My iPhone, which must be turned off before the reset can complete. After confirming, the iPhone shows a progress bar and reboots to the initial setup screen, which takes anywhere from two to fifteen minutes depending on the model and the amount of data being erased.
If the iPhone has an active eSIM, the reset process asks whether to erase or retain it. When selling the device, erase the eSIM. When resetting for personal use and planning to restore from backup, retaining it saves the step of re-adding the carrier plan.
The iPad reset process follows the same Settings pathway, so users managing both devices will find the steps familiar.
How to Factory Reset iPhone via Recovery Mode
Recovery mode is the correct path when the iPhone is disabled due to too many wrong passcode attempts, completely frozen and unresponsive, or when the normal reset through Settings cannot be completed. This method requires a Mac running Finder, or a Windows PC with the Apple Devices app installed.
Connect the iPhone to the computer with a USB cable. Then enter recovery mode using the force restart button sequence for the specific model — but instead of releasing the Side button when the Apple logo appears, keep holding it until the recovery mode screen appears (a cable icon pointing toward a computer). Finder or the Apple Devices app will detect the device in recovery mode and offer a Restore option. Selecting Restore downloads the latest iOS version from Apple’s servers and installs it, erasing all data in the process.
Recovery mode is also the standard solution when an iPhone gets stuck in a boot loop after a failed iOS update. It bypasses the corrupted update entirely and installs a fresh copy directly from Apple. Users who need to manage or reset other Apple devices like AirPods will find a separate but similarly straightforward process for those accessories.
DFU Mode: The Deepest Level of Reset
Device Firmware Update (DFU) mode bypasses both iOS and the bootloader, allowing iTunes or Finder to install firmware from scratch without loading the current operating system at all. This is deeper than recovery mode and is specifically for situations where recovery mode itself fails, or when reversing a jailbreak, fixing a corrupted baseband, or restoring a device that won’t enter normal recovery mode.
For iPhone 8 and later: connect the device to a computer, press and release Volume Up, press and release Volume Down, press and hold the Side button for exactly three seconds, then — while still holding Side — press and hold Volume Down for five seconds, then release the Side button while continuing to hold Volume Down for another five seconds. If done correctly, the screen remains completely black (no Apple logo). Finder or iTunes will show a message that the device is in recovery mode. Select Restore to proceed.
DFU mode is not needed for standard troubleshooting. It exists for edge cases that standard restores cannot resolve. Attempting it unnecessarily carries a risk of bricking the device if the process is interrupted midway.
Resetting Specific Settings Without a Full Wipe
iOS provides targeted reset options under Settings > General > Transfer or Reset iPhone > Reset that address specific problem areas without erasing personal data. These are genuinely useful alternatives when a full factory reset is unnecessary.
Reset All Settings restores every system preference — display brightness, notification settings, Privacy settings, keyboard preferences, VPN configurations, and Wi-Fi passwords — to default, while leaving all apps, photos, contacts, and files completely untouched. This is the correct first step when the iPhone behaves strangely after an iOS update but all data is intact.
Reset Network Settings clears all saved Wi-Fi networks and passwords, Bluetooth pairings, VPN configurations, and cellular settings. Use this when persistent Wi-Fi disconnections, cellular data problems, or Bluetooth pairing failures survive a standard restart. It is far less disruptive than a full reset and resolves the majority of connectivity complaints.
Reset Keyboard Dictionary removes all custom words and autocorrect entries that have accumulated over time. Useful when autocorrect has learned incorrect spellings and keeps substituting wrong words.
Reset Home Screen Layout returns all app icons to the default Apple arrangement. This does not delete any apps — it simply reorganizes the home screen as it appeared on a new device.
FAQ: iPhone Restart and Reset Questions
Does a hard reset delete everything on iPhone?
No. A hard reset, also called a force restart, does not erase any data. It reboots the operating system at the hardware level, which fixes freezes and crashes without touching files, apps, photos, messages, or settings. Only a factory reset using Erase All Content and Settings permanently removes data from the device.
How do I restart my iPhone if the screen is unresponsive?
Use the force restart sequence for the model. On iPhone 8 and all later models, quickly press Volume Up, quickly press Volume Down, then press and hold the Side button for 10 to 15 seconds until the Apple logo appears. This works regardless of whether the touchscreen responds, because it operates entirely through hardware buttons.
What should I do before a factory reset?
Back up the device to iCloud through Settings > Apple ID > iCloud > iCloud Backup, or connect to a computer and back up through Finder (Mac) or Apple Devices (Windows). After backing up, sign out of Apple ID under Settings > Your Name > Sign Out. This disables Find My iPhone, which must be off before the factory reset can complete. Without a backup, all data is permanently unrecoverable after the wipe.
How often should an iPhone be restarted?
Apple does not specify a mandatory schedule, but a soft restart once a week is a widely recommended practice for maintaining performance. iOS manages memory automatically, but regular restarts clear accumulated temporary data, terminate background processes that may have stalled, and keep the system running at its intended speed. Devices that stay on for weeks without a restart often show gradual slowdown that a restart immediately resolves.
Can a factory reset fix a software problem that restarts cannot?
Yes. Persistent software corruption — particularly after a failed iOS update, a jailbreak attempt, or repeated app crashes that survive multiple force restarts — often requires a clean iOS installation to resolve. A factory reset followed by a restore from a clean backup eliminates the corrupted software layer entirely. If the problem returns after restoring, the issue may originate in the backup itself, in which case setting up as a new device is the appropriate next step.
Tips to Prevent iPhone Crashes and Freezes
Keep iOS updated through Settings > General > Software Update. Apple releases bug fixes and stability improvements in each update, and running an outdated version leaves known issues unaddressed. Enabling automatic updates ensures critical patches install without manual intervention.
Monitor storage through Settings > General > iPhone Storage. Devices running below 1 to 2 GB of free space experience significantly more crashes and slowdowns, because iOS needs working space to manage memory, process photos, download updates, and operate normally. Deleting unused apps, offloading large media files, and clearing app caches regularly prevents storage from becoming a performance bottleneck. Users experiencing persistent touch screen freezes on any device will find that storage management and regular restarts address the majority of cases.
Avoid letting the battery drain to zero regularly. Frequent deep discharge cycles accelerate battery chemical degradation, which over time causes the system to throttle performance to protect battery longevity. Keeping charge between 20% and 80% where practical extends battery health and reduces the performance slowdowns that Apple implements on aging battery units.
Remove apps that consistently crash or behave erratically. A single poorly coded app with a memory leak can degrade system-wide performance. The Battery section in Settings identifies apps with high background activity — disabling background refresh for those apps is a low-effort fix that noticeably improves stability.
Choosing the Right Reset Method
The decision tree is straightforward. For any performance issue where the screen still responds normally, start with a soft restart. If the screen is frozen and touch input has no effect, use the force restart button sequence immediately — it resolves the majority of serious software crashes without any data loss. If the device has deep, recurring software problems that restarts cannot fix, or if the phone is being prepared for sale, a factory reset through Settings is the appropriate step.
Recovery mode and DFU mode are reserved for situations where the device cannot complete a normal reset — failed updates, disabled devices, and cases where iTunes or Finder needs direct firmware access. The remote erase option through iCloud’s Find My is available for devices that are lost or stolen and cannot be reached physically.
Understanding these methods in sequence means no situation leaves the user without options. From a routine weekly restart to a complete firmware reinstall, every scenario has a defined, tested path that Apple documents and supports. The key is matching the severity of the problem to the appropriate level of intervention — starting with the least disruptive option and escalating only when needed.
