After using a phone for a period of time, users often encounter unexpected problems and errors. One of the most common issues is when the phone turns off on its own without any apparent reason. Usually, users will try to restart their phone to fix the error, but in fact, this action can damage the device. The following article by FPT Shop will provide you with some of the reasons why phones frequently turn off on their own, as well as effective ways to resolve this situation.

Low-quality phone battery

A low-quality phone battery is one of the main causes of automatic power-offs. When the battery is drained, the phone is often unable to maintain power and will automatically turn off. To minimize the occurrence of battery drain, there are several measures you can take:

Do not use the phone while it’s charging: Using the phone while it’s charging can cause high temperatures and reduce the battery’s lifespan.
Avoid exposure to high temperatures: High temperatures can quickly damage the battery. Avoid leaving your phone in environments with high temperatures for prolonged periods.
Use an original charger: Using an original charger will help protect the battery and ensure safe charging.
Avoid letting the battery run completely flat before charging: To ensure battery longevity, avoid letting the battery completely discharge before recharging.

If you encounter the issue of your phone turning off on its own, you can try charging the battery for about half an hour to see if the phone can be restarted. If the problem persists, the battery may be faulty and needs to be replaced at an authorized service center or reputable store. This will help your phone operate stably and avoid unexpected automatic power-offs. Refer to how to check if your iPhone battery has been activated.

Software errors on the device

Software errors are a common cause of phones turning off automatically. This can result from installing incompatible apps or apps that conflict with the operating system.

How to fix: Perform a factory reset to return the device to its original state. Remember to back up your data before performing these steps.

For iPhones

Step 1: From the phone’s home screen, open the Settings app → Select General → Scroll down and select Reset.

Step 2: Next, tap on Erase All Content & Settings → Select Delete Now. The system will restart the device and restore it to its original factory settings so that the device can stabilize itself as before.

For Android phones

Step 1: Similar to iPhones, access Settings on the phone’s home screen → Scroll down and select Backup & Reset → Then select Factory Reset.

Step 2: Here, select Erase All Content and Settings. The system will ask for confirmation from the user to erase all data on the phone → simply tap OK to confirm.

The phone has a hardware fault

If you have accidentally knocked your phone hard (e.g., in a handbag) or dropped it, this may have caused issues related to the device’s hardware. These consequences can lead to the phone turning off on its own without any apparent reason.

In this situation, the only way to fix the problem is to take your phone to an authorized service center or a reputable phone repair shop.

Here, technical experts will inspect and identify the specific problem with your phone, then provide appropriate solutions and perform the necessary repairs. This way, you can be assured that your phone’s issue is resolved accurately and effectively.

CPU is operating at a high level

Another reason that can cause a phone to turn off on its own is that the CPU system is being overloaded due to running too many background apps. This leads to high power consumption and requires the CPU to reset, causing a power-off.

To determine the cause, you can check after installing a new app. Try uninstalling the app and restarting the device to see if the problem resolves.

Additionally, you can remove each app on your phone one by one and restart the device to check if the problem persists.

The phone’s power button is faulty

If you have tried many fixes but your phone still keeps having power-off issues, it could be that the power button of your phone is experiencing problems. In this situation, it is essential to check the hardware of the power button.

Usually, most devices running the Android operating system will automatically restart after about 8 to 10 seconds when the power button is held. If the power button isn’t working properly, this can lead to the device automatically restarting frequently or turning off abruptly.

To resolve this situation, you should first remove the phone case (if you have experience and knowledge). Then, check if the power button is stuck or broken.

If you find that the power button is broken, take your phone to a reputable phone repair shop for professional inspection and repair. This ensures that your phone operates stably and can be used normally without encountering unexpected power-off issues.
