Phone Keeps Restarting | Simple Powerful Fixes That Work

Phone keeps restarting when you are trying to use it? You are not alone. A phone that turns off and starts again without warning can be annoying, especially when it happens several times a day.

A phone keeps restarting for different reasons. It could be caused by a faulty app, low storage, a software problem, an ageing battery, overheating, a damaged charging port, or an internal hardware fault. The exact cause can be difficult to find because the phone may restart without showing an error.

The good news is that you can try several safe checks before taking your phone to a repair shop. In this guide, we explain why a phone keeps restarting, what you can check at home, what you should avoid, and when professional phone repair may be needed.

Why Does a Phone Keep Restarting?

A phone is made up of many parts that need to work together. The operating system controls the phone, apps use memory and processing power, the battery provides power, and the internal hardware keeps everything running.

When something goes wrong, the phone may restart as a way of recovering from the problem.

Sometimes the cause is simple. For example, an app may have a software bug or the phone may have very little free storage.

Other times, the problem can be linked to the battery, charging system, water damage, a previous drop, or another internal component.

If your phone only restarts once, you may not have a serious problem. But if your phone keeps restarting several times a day, the issue should not be ignored.

Phone Keeps Restarting Because of a Bad App

One of the first things to check is your recently installed or updated apps.

An app can sometimes contain a bug or have a problem that causes the operating system to become unstable. This may happen after installing a new app or after an app receives an update.

Google’s official Pixel troubleshooting guide recommends checking apps when a Pixel phone randomly restarts or crashes. Google also recommends using Safe Mode to help identify whether a downloaded app is causing the problem.

Think about when the restarting started.

Did you install a new app shortly before the problem appeared?

Did you update several apps?

Does the phone restart when you open one particular app?

These details can help you find the cause.

What to Do About a Problem App

Start by updating your apps through the official app store.

If the problem started after installing a particular app, remove that app temporarily. Then use your phone normally and see whether the restarting stops.

On Android phones, Safe Mode can also help. Safe Mode temporarily prevents downloaded apps from running. If your phone works normally in Safe Mode, a downloaded app may be involved.

The exact steps for Safe Mode are different between phone brands and models, so check the instructions for your device.

Low Storage Can Make a Phone Unstable

Your phone needs free storage to work properly.

Storage is used for photos, videos, apps, downloads, temporary files, system files and other information. When your storage becomes almost full, your phone may have difficulty completing normal tasks.

Google’s Pixel support guidance says a phone can have issues when less than 10% of its storage is available.

Check your storage if your phone keeps restarting.

Look for large videos, old downloads, unused apps and other files you no longer need. Before deleting important photos or documents, make sure they are backed up somewhere safe.

After freeing some space, restart your phone and use it normally.

If the phone becomes stable again, low storage may have been part of the problem.

A Software Update May Be Needed

Your phone’s operating system controls many of its important functions. Software problems can sometimes cause crashes, freezes and unexpected restarts.

Check whether a software update is available for your phone.

On Android, the update section is normally found inside Settings. On an iPhone, you can check for updates under the software update settings.

Apple’s official support information recommends keeping an iPhone updated and notes that an iOS update can sometimes resolve an issue.

Before installing a major update, make sure your important information is backed up.

If your phone started restarting immediately after an update, give it some time and check for another available update. If the problem continues, the software installation or another part of the system may need further troubleshooting.

Phone Keeps Restarting Because of an Ageing Battery

The battery is another part worth checking.

Phone batteries naturally wear down as they are used. As a battery ages, you may notice shorter battery life, unexpected shutdowns, slow charging or other unusual behaviour.

In some cases, a battery problem can cause a phone to shut down and restart.

Pay attention to other signs.

Does the battery drop quickly?

Does the phone turn off when the battery level still shows plenty of charge?

Does it restart when you open a demanding app?

Does the phone become unusually warm?

These signs can help a technician understand whether the battery could be involved.

If you notice that the back of your phone is lifting, the screen is separating from the frame, or the battery looks swollen, stop using the phone and do not try to open it yourself.

A damaged battery should be handled by a trained repair technician.

Overheating Can Cause Unexpected Restarts

Phones have built-in systems that help protect them from excessive heat.

Heavy gaming, long video calls, navigation, charging, direct sunlight and hot surroundings can all make a phone warmer.

If the phone becomes too hot, it may reduce performance, stop charging, shut down, or behave differently to protect its internal components.

If your phone keeps restarting when it is hot, stop using demanding apps and move the device away from direct sunlight.

Do not put a hot phone in a freezer or refrigerator. Sudden temperature changes can create condensation and may cause additional problems.

If the phone remains unusually hot even when you are not using it, the cause may be more serious.

You can also read FoneDoc’s guide about phone overheating for more information.

Check Your Phone Charger and Charging Port

A charging problem can sometimes be connected to unexpected shutdowns or restarts.

A damaged cable, faulty charger or dirty charging port may prevent the phone from receiving stable power.

Check the charging cable for visible damage. Look at the connector and check whether the cable feels loose when connected.

You should also look inside the charging port.

Pocket lint and dust can collect inside the port over time. However, do not use a pin, needle or other metal object to dig inside the port. You could damage delicate contacts.

If the phone restarts mainly while charging, try a suitable charger and cable from a trusted source.

If the problem continues, the charging port or another internal component may need to be inspected.

A Drop Can Cause a Phone to Keep Restarting

A phone does not need to look badly damaged to have an internal problem.

A hard drop can affect internal connectors, the battery, display components, charging system or motherboard.

Sometimes the phone continues working after a drop and the problem appears later.

If your phone started restarting after being dropped, take note of when the restarting happens.

For example, does it restart when you move the phone?

Does it restart when you press the frame?

Does it restart when the phone is charging?

Does it restart when you open certain apps?

These details can help a technician identify the possible source of the problem.

If the phone has been dropped recently and the restarting continues, professional testing is safer than repeatedly resetting the device.

Water Damage Can Lead to Random Restarts

Liquid damage can create problems that do not appear immediately.

Water or another liquid can reach internal components through openings such as the charging port, speaker area or other gaps.

Even after the outside of the phone looks dry, moisture or residue can remain inside.

A phone may initially appear to work normally and later develop charging problems, battery problems, sound problems, screen problems or unexpected restarts.

If your phone was recently exposed to water and then started restarting, turn it off if you can do so safely.

Do not keep charging it to check whether it works.

Do not put it in rice.

Professional inspection can help identify whether liquid has reached the internal components.

FoneDoc provides water damage repair in Perth and can inspect devices affected by liquid.

Try a Simple Restart First

It may sound strange to restart a phone that is already restarting, but a normal restart can help when a temporary software process has become stuck.

If your phone is working normally between random restarts, use the normal restart option from the power menu.

If the phone is frozen and does not respond, the force restart process depends on the device.

For newer iPhones without a Home button, Apple says to quickly press and release the volume up button, quickly press and release the volume down button, then press and hold the side button until the Apple logo appears.

Android phones have different button combinations depending on the manufacturer and model.

Do not repeatedly force restart the phone if the problem continues. If it keeps happening, focus on finding the cause.

Check How Much Storage You Have

After restarting, check your available storage.

Remove things you no longer need, such as:

• Old videos
• Large downloads
• Unused apps
• Duplicate photos
• Offline media
• Large files

Do not delete files simply because they are large. Make sure you know what they are first.

If your phone has very little free space, create a backup and remove unnecessary files.

After making some space, monitor the phone for a while.

Check Battery Usage

Your battery settings can provide useful clues.

Look for apps or services using much more battery than expected.

For example, if an app you rarely use is consuming a large amount of battery, update it or remove it temporarily.

A phone that is restarting and losing battery unusually quickly may have a battery or software problem.

However, battery usage alone cannot confirm that a battery is faulty. It is one clue among several.

If the phone continues restarting after you have checked your apps, storage and software, it may need a hardware inspection.

Try Safe Mode on Android

If you have an Android phone, Safe Mode can help separate app problems from other problems.

Safe Mode temporarily disables downloaded apps. If the phone stops restarting while in Safe Mode, a downloaded app may be causing the problem.

Google recommends this approach for Pixel phones that restart or crash unexpectedly.

If the phone still restarts in Safe Mode, the cause may not be a normal third-party app.

Do not assume that Safe Mode proves the exact cause. It is a troubleshooting step that helps narrow down the problem.

Should You Factory Reset a Phone That Keeps Restarting?

A factory reset can sometimes fix serious software problems, but it should not be your first step.

A factory reset removes your personal information, apps and settings from the phone.

Google specifically warns that a factory data reset removes data from the device and recommends backing up important information first.

Before considering a factory reset:

1. Back up your photos and important files.
2. Make sure you know your account passwords.
3. Check whether the problem is caused by an app.
4. Check available storage.
5. Install available software updates.
6. Check the battery and charging behaviour.

If the phone continues restarting after a clean factory reset, that can be a useful sign that the problem may not simply be an app or normal user setting.

At that point, professional diagnosis may be more useful than repeatedly resetting the phone.

When Is a Restarting Phone a Repair Problem?

A phone keeps restarting for many possible reasons, so there is no single repair that works for every device.

You should consider getting the phone checked if:

• It restarts several times every day.
• It restarts even when you are not using it.
• It becomes very hot.
• The battery drains unusually fast.
• It shuts down during charging.
• The phone was recently dropped.
• The phone was exposed to water.
• The screen or back cover is lifting.
• It restarts after a battery replacement.
• It continues restarting after software troubleshooting.
• It will not stay switched on long enough to use normally.

A technician can inspect the device and check whether the problem is related to the battery, charging system, software, liquid damage or another internal component.

How to Prevent Random Phone Restarts

You cannot prevent every phone problem, but a few simple habits can reduce avoidable issues.

Keep your phone’s software and apps updated. Remove apps that you no longer use, especially if they cause crashes or unusual battery drain.

Try to keep some free storage available. A phone that is completely full can have difficulty completing normal tasks.

Avoid exposing your phone to extreme heat. Do not leave it in direct sunlight or inside a hot parked car.

Use suitable charging accessories and replace damaged cables.

Keep your phone away from water even if it has some level of water resistance. Water resistance is not the same as being completely waterproof, and seals can also be affected by damage or previous repairs.

Use a protective case if you are likely to drop your phone, but make sure the case does not interfere with buttons, ports or ventilation.

Most importantly, do not ignore repeated restarts. A problem that happens once may be temporary, but repeated restarting deserves attention.

Conclusion

A phone keeps restarting when something is preventing it from running normally. The cause can be as simple as a problem app or low storage, but it can also involve the battery, charging system, overheating, liquid damage or internal hardware.

Start with the simple checks. Update your software and apps, check your storage, look at battery usage, remove a recently installed problem app and test the phone in Safe Mode if your Android device supports it.

Avoid opening the phone yourself, especially if you suspect a damaged or swollen battery.

If the phone continues restarting after these checks, professional diagnosis can help identify the real problem.
