How to Restart iPhone
Learn how to restart an iPhone, when to use force restart, what to try first, safe steps by model type, mistakes, troubleshooting, and FAQs.
Quick Answer
To restart most newer iPhones, hold the side button and a volume button until the power slider appears, slide to power off, wait for shutdown, then hold the side button again until the Apple logo appears. Use force restart only when the phone is frozen.
Before You Start
- Charged iPhone or charger nearby
- Passcode after restart
- Model awareness for button combination
- Recent backup optional
Safety Precautions
- Save open work before restarting if the screen responds.
- Do not force restart during an iOS update unless the device is clearly stuck for a long time.
- Use Apple model-specific instructions if your buttons differ.
- If the phone is hot, swollen, wet, or damaged, stop and get professional service.
- Know your passcode because Face ID or Touch ID may require it after restart.
Step-by-Step Instructions
- Step 1
Try a normal restart
Hold the side button and a volume button on Face ID models until the slider appears.
- Step 2
Power off
Drag the slider and wait until the screen goes completely dark.
- Step 3
Turn it back on
Hold the side button until the Apple logo appears.
- Step 4
Use Settings if buttons fail
Open Settings, General, Shut Down, then turn the phone on again with the side button.
- Step 5
Force restart only if frozen
For many recent models, press volume up, press volume down, then hold the side button until the Apple logo appears.
- Step 6
Enter passcode
Unlock with your passcode after the restart finishes.
Practical Example
Example: An app freezes your iPhone screen. You try the normal slider, but it does not respond, so you use the model-specific force restart sequence and then update the app.
Common Mistakes
- Using force restart for every minor issue
- Letting battery drain during troubleshooting
- Interrupting updates
- Forgetting passcode
- Using wrong button sequence for older models
- Assuming restart deletes data
