How to Restart iPhone: A Complete Guide for Every Model

Restarting your iPhone might seem like a simple task, but the method you use depends on your model and iOS version. Whether you’re trying to fix a glitch, free up memory, or refresh performance, knowing how to restart iPhone properly can solve a range of common issues. From the iPhone 6 to the latest iPhone 15 Pro Max, Apple has subtly changed how restarting works over the years.

In this guide, we’ll break down how to restart every iPhone model, why you might need to do it, and what to do if your phone becomes unresponsive. Whether you’re a new Apple user or a longtime fan, understanding how to restart iPhone the right way ensures your device stays in top shape.

Why Restarting Your iPhone Matters

You may wonder why it’s even necessary to know how to restart iPhone. After all, iPhones are designed for efficiency and reliability. However, like any electronic device, they benefit from the occasional reboot. Restarting helps to:

• Clear background memory clutter

• Solve app crashes or freezes

• Fix minor software glitches

• Improve overall speed and responsiveness

• Install updates more smoothly

For instance, when your screen freezes or an app refuses to load, a quick restart can bring everything back to normal. It’s also a recommended first step before contacting tech support or visiting an Apple Store.

Even newer models like the iPhone 15 Pro Max or iPhone 14 Pro benefit from a restart after installing major iOS updates. It’s a simple habit that can prevent larger issues from developing.

How to Restart iPhone 15, 14, 13, 12, and X Series

If you own an iPhone with Face ID—like the iPhone X, iPhone 11, iPhone 12, iPhone 13, iPhone 14, or iPhone 15—the method for restarting your phone is consistent across all of them. Here’s how to restart iPhone models in this range:

1. Press and hold the Side button (on the right side) and either Volume button (up or down) at the same time.

2. You’ll see the “slide to power off” screen appear.

3. Drag the slider to turn off your iPhone.

4. Once the screen goes black, wait 10–15 seconds.

5. Press and hold the Side button again until you see the Apple logo appear.

Your iPhone will now restart and boot up as normal. This is considered a soft restart, meaning you’re turning the phone off and on without affecting any data or settings.

How to Restart iPhone SE (2nd & 3rd Gen), iPhone 8, and iPhone 7

Older models without Face ID but still relatively modern—like the iPhone SE 2nd generation, iPhone SE 3rd generation, iPhone 8, and iPhone 7—have a slightly different button layout. Here’s how to restart iPhone models in this category:

1. Press and hold the Side button until the “slide to power off” screen appears.

2. Drag the slider to power off.

3. Wait about 10 seconds for it to shut down completely.

4. Hold the Side button again until you see the Apple logo.

These devices don’t use the volume button combination that newer models require. The restart process is straightforward and effective.

How to Restart iPhone 6s, iPhone 6, and iPhone SE (1st Gen)

If you’re still using a classic iPhone like the iPhone 6s, iPhone 6, or the first-generation iPhone SE, the power button is located on the top or side, depending on your model. Here’s how to restart iPhone units from these earlier releases:

1. Press and hold the Top (or Side) button until the power-off slider appears.

2. Slide to power off.

3. After the screen goes black, wait about 10 seconds.

4. Press and hold the Top (or Side) button again until the Apple logo appears.

These iPhones rely on simpler button configurations, making the restart process familiar and user-friendly.

How to Force Restart iPhone (Hard Reset)

Sometimes, your iPhone might become completely unresponsive. Maybe the screen is black, the phone is frozen, or the touch isn’t working. In these situations, knowing how to restart iPhone via a force restart is crucial.

Here’s how to force restart depending on your model:

For iPhone 8 and later (including all Face ID models):

1. Quickly press and release the Volume Up button.

2. Quickly press and release the Volume Down button.

3. Press and hold the Side button until the Apple logo appears, then release.

For iPhone 7 and iPhone 7 Plus:

1. Press and hold the Volume Down button and the Side button at the same time.

2. Keep holding until the Apple logo appears.

For iPhone 6s and earlier:

1. Press and hold the Home button and Top (or Side) button together.

2. Hold both until the Apple logo appears.

A force restart doesn’t erase any data. It’s just a more aggressive way to get your iPhone running again when a normal restart isn’t possible.

When Should You Restart Your iPhone?

While you don’t need to restart your iPhone daily, doing it once every few days can keep your device running smoothly. You should also consider restarting in the following cases:

• After a major iOS update

• When apps begin crashing or freezing

• If your battery drains faster than usual

• When your iPhone feels hot or is overheating

• If the device is not responding or running slower than expected

Restarting is one of the easiest troubleshooting steps you can take, and it’s often enough to resolve temporary performance issues.

Restarting with AssistiveTouch

If your power or volume buttons are damaged, you can still learn how to restart iPhone using AssistiveTouch, Apple’s accessibility feature. Here’s how:

1. Go to Settings > Accessibility > Touch > AssistiveTouch and turn it on.

2. Tap the on-screen AssistiveTouch button.

3. Choose Device > More > Restart.

4. Confirm the action.

This feature is a lifesaver if you’re dealing with a broken button or need an alternative way to control your iPhone.

Restart vs Reset: Know the Difference

Many people confuse the terms “restart” and “reset.” When learning how to restart iPhone, it’s important to know that a restart simply turns your phone off and back on again. No data is lost. A reset, on the other hand, can mean:

• Soft reset: Another term for restart.

• Factory reset: Erases all data and settings, returning your iPhone to its original state.

Always back up your iPhone to iCloud or a computer before performing a factory reset. If you’re simply trying to fix minor issues, a restart is usually sufficient.

Best Practices for iPhone Maintenance

Restarting is just one aspect of keeping your iPhone in good shape. To ensure optimal performance:

• Keep your iOS updated

• Avoid running too many apps in the background

• Clear Safari cache regularly

• Restart your device at least once a week

• Use a reliable charger and avoid third-party cables

Following these tips will help you avoid the need for frequent restarts and prolong your device’s life.

Troubleshooting: What If Your iPhone Won’t Restart?

If you’ve followed the steps and your iPhone still won’t restart, consider the following:

• Charge your device: If the battery is drained, plug it in for 15 minutes before trying again.

• Check your buttons: A faulty Side button may require repair.

• Try force restarting: Use the appropriate method for your model.

• Use Finder or iTunes: Connect your iPhone to a computer and see if it’s detected.

If none of these steps work, you may need to contact Apple Support or visit a certified technician. For those in wholesale or resale, sourcing Apple devices through Supplier Central offers access to quality products with verified supply chains.

Final Thoughts

Learning how to restart iPhone is a basic but essential skill for all Apple users. Whether you’re using the latest iPhone 15 Pro Max or holding onto an older model, knowing how to do a soft or force restart can save you time, prevent frustration, and even extend the life of your device.

Restarting clears out temporary bugs, enhances performance, and is often the first recommended solution for most iOS issues. It’s a quick fix that can keep your iPhone running like new.

So the next time your device feels a bit sluggish or acts up, don’t panic—just restart it.
