OnePlus 6 Keeps Restarting: Fixes That Work

If your OnePlus 6 keeps restarting on its own, the fix usually involves clearing the cache, updating the software, or checking for a failing battery. Start by restarting in Safe Mode to rule out a misbehaving app, then try wiping the cache partition from Recovery Mode. If the problem persists, it may be a hardware issue, especially with the battery or power button.

Why Does the OnePlus 6 Restart Randomly?

The OnePlus 6, released in 2018, runs on OxygenOS (based on Android). Random restarts can stem from several causes:

• Software glitches – bugs introduced after a system update or app update.
• App conflicts – a third-party app crashing the system UI or causing kernel panic.
• Battery degradation – an aging battery can drop voltage under load, causing the phone to shut down and reboot.
• Overheating – prolonged heavy use or exposure to heat can trigger a safety reboot.
• Hardware faults – a loose battery connector, damaged power button, or motherboard issue.

Understanding the cause helps you choose the right fix. Most software-related issues are solvable at home; hardware problems may require professional repair.

Quick Fixes to Try First

Before diving into advanced troubleshooting, try these simple steps:

1. Force restart – Press and hold the power button for 10-15 seconds until the phone vibrates and reboots. This clears minor glitches.
2. Check for software updates – Go to Settings > System > System Updates and install any pending updates. OnePlus has released several updates to fix reboot bugs.
3. Free up storage – If your storage is almost full, the system may struggle. Delete unused apps and files.
4. Remove the SIM card and SD card – A faulty SIM or SD card can sometimes cause restarts. Remove them and see if the issue stops.

If these don’t help, move on to the more targeted solutions below.

How to Boot into Safe Mode and Uninstall Problem Apps

Safe Mode starts your phone with only pre-installed apps. If the restarting stops in Safe Mode, a third-party app is the culprit.

1. Press and hold the power button until the power menu appears.
2. Tap and hold the “Power off” option until you see a prompt to reboot into Safe Mode.
3. Tap OK to confirm. The phone will restart, and “Safe Mode” will appear at the bottom left.
4. Use the phone normally for a few hours. If no restarts occur, an app is causing the problem.
5. To exit Safe Mode, simply restart the phone normally.

Once in Safe Mode, uninstall recently downloaded apps that you suspect. Start with apps that have background services, such as launchers, battery savers, or VPNs. After uninstalling, restart the phone and observe.

Clearing the Cache Partition

A corrupted cache partition can cause system instability. Clearing it doesn’t delete your personal data, so it’s safe to try.

1. Turn off the phone completely.
2. Press and hold the Volume Down and Power buttons simultaneously until the OnePlus logo appears, then release.
3. Use the volume keys to navigate to “English” and press the power button to select.
4. Select “Wipe data and cache” (note: this will NOT erase your data if you choose “Wipe cache” only).
5. Choose “Wipe cache” and confirm.
6. After the process, select “Reboot”.

If you don’t see the Recovery Mode menu, try the key combination again. Some OnePlus 6 units use Volume Up instead of Volume Down.

Factory Reset: The Last Software Resort

If Safe Mode and cache clearing don’t work, a factory reset will restore the phone to its original state. This erases all data, so back up your photos, contacts, and files first.

1. Go to Settings > System &em; Reset options > Erase all data (factory reset).
2. Tap Erase all data and confirm.
3. The phone will restart and set up as new.

After the reset, set up the phone without restoring from a backup first. If the restarts stop, the issue was in the software. If they continue, it’s likely hardware.

Hardware Issues: Battery, Power Button, and Motherboard

If software fixes fail, the problem is physical. The most common hardware issue is a degraded battery. Over time, lithium-ion batteries lose capacity and can cause voltage drops that trigger reboots. Symptoms include rapid battery drain, unexpected shutdowns below 20%, and swelling (visible bulge on the back).

A faulty power button can also cause restarts if it gets stuck or sends false signals. Try pressing the power button firmly a few times; if the phone reboots, the button may be the issue.

Motherboard problems, though less common, can also cause random restarts. This is often due to a loose connection or a damaged component. In such cases, professional repair is recommended. A reputable repair shop can diagnose and replace the faulty part.

When to Seek Professional Repair

If you’ve tried all the above and the phone still restarts, it’s time for professional help. Look for a repair service that specializes in OnePlus devices. They can run diagnostics to pinpoint the issue. Battery replacement is typically the most affordable fix; motherboard repairs can be costly, sometimes exceeding the phone’s value.

Before paying for repairs, consider the age of the device. The OnePlus 6 is now several years old, and repair costs might be better spent toward a new phone. However, if you’re attached to the device or want a backup phone, a battery replacement is often worth it.

Frequently Asked Questions

Why does my OnePlus 6 restart when I open the camera?

The camera app uses significant processing power and battery. If your battery is weak, the sudden power draw can cause a reboot. Try replacing the battery first. Also, clear the camera app’s cache by going to Settings > Apps > Camera > Storage and tapping “Clear Cache.”

Will a factory reset delete my photos?

Yes, a factory reset erases all data on the internal storage, including photos, videos, and messages. Back them up to Google Photos, a computer, or an external drive before resetting.

Can a virus cause my OnePlus 6 to restart?

While Android viruses are rare, malware can cause system instability. If you suspect malware, install a reputable antivirus app and run a scan. Also, avoid installing apps from unknown sources and keep Google Play Protect enabled.

Is there a way to stop restarts without losing data?

Yes, try Safe Mode and clearing the cache partition first. These methods don’t erase personal data. If they don’t work, you may need to back up and then factory reset.

How do I know if my battery is the problem?

If the phone restarts when the battery is below 30% or when using heavy apps, the battery is likely failing. You can also check battery health using apps like AccuBattery, which estimate wear level. A battery with health below 80% is a prime suspect.

What if my OnePlus 6 keeps restarting after a system update?

Sometimes updates introduce bugs. Check for a newer update that might fix it. If not, try clearing the cache partition or doing a factory reset. If the problem persists, downgrade to the previous version using OnePlus’ official tools, but this requires unlocking the bootloader and may void warranty.
