If my phone switches off on its own, it can be because of several reasons. It can be due to a low or damaged battery, overheating, software problems, a stuck power button, faulty apps, low storage or RAM, or even charging issues. Most of these problems are common and can usually be fixed at home by doing simple things. But if the issue continues even after trying these steps, the phone may need professional repair.
This problem of switching off automatically or shutting down suddenly affects a lot of users. In this guide, I will explain the possible reasons and show step-by-step solutions to fix them. The goal is to help you understand the problem clearly and get your phone working again. Let’s get started:
Issue 1: Battery Health Or Damage

One of the most common reasons a phone shuts down suddenly is a worn-out or damaged battery. As the battery gets older, it may not be able to hold enough charge to keep the phone running properly.
How To Identify Battery Problems?
You might be facing battery issues if:
- Your phone switches off even when the battery level is between 20 and 50 percent.
- The battery drains much faster than it used to.
- The phone feels hot or swollen near the battery area.
Simple Step-by-Step Fixes
You can try these easy solutions at home:
- Go to Settings > Battery and see if any app is using too much power
- Charge the phone to 100 percent and use it until it turns off. After this, charge it fully again without breaks.
- If the phone has a removable battery, you can try a new one. For phones with built-in batteries, you can use a battery health app from the app store to check its condition.
If the phone is still under warranty or if the battery looks swollen, you should take it to an authorised service center immediately. You should avoid trying to replace the battery yourself in sealed phones, as it may cause more damage.
Issue 2: Overheating Issues

Overheating is another common reason behind phone switching off on its own. When my phone gets too hot, it shuts down on its own to protect the internal parts from damage.
How To Spot Overheating?
You can tell your phone is overheating if:
- The phone feels very warm while using it or charging
- It switches off during heavy tasks like gaming, video calls, or long online classes
- You see warning messages about high temperature on the screen
Easy Fixes You Can Try
You can try these simple steps to cool down your phone:
- Taking off the cover helps the phone release heat faster.
- Keep the phone in a cool and shaded place to avoid direct sunlight.
- Use the app switcher to close apps that are running unnecessarily.
- Many heating problems reduce after installing the latest system updates
If phone keeps overheating even when it is not in use or after it has cooled down, it could be a hardware issue. In that case, visit a repair centre to check for problems like a faulty processor or internal damage.

Issue 3: Software Bugs or Outdated OS

Sometimes, a phone keeps turning off because of software bugs or an outdated OS. If the software is not working properly, the phone may restart or shut down suddenly without any warning.
Signs Of Software Problems
Y may be facing a software issue if:

Step-by-Step Solutions
You can try these simple fixes to solve software-related problems:
- Press and hold the power button and tap Restart

- Press and hold the power button. After this, long-press Restart to enter safe mode and check if third-party apps are causing the issue.
- Factory reset is the last resort. First back up all important data, then go to Settings > System > Reset options and reset the phone
If software updates do not fix the issue, it is best to visit a service centre. A technician may need to reinstall the operating system to solve the problem properly.
Issue 4: App-Related Problems

Sometimes, certain apps can put too much pressure on the phone. It can cause it to switch off automatically. This usually happens when an app is poorly designed or not compatible with the phone’s software.
How To Know These App Issues?
You might be facing an app-related problem if:
- The phone shuts down right after opening a specific app.
- Your phone crashes while multitasking.
- The issue started after installing a new app.

- Remove newly installed apps from the app drawer or settings
- Go to Settings > Apps > Storage and clear the cache of the app causing trouble
In most cases, professional help is not needed. If the problem continues, a software technician can check for deeper issues.
Issue 5: Running Out of Space

If your phone’s storage is full or RAM is low, the system may shut down to prevent crashes. This is common in phones with limited internal storage.
How To Know Memory Overload Signs
You may notice:
- Low storage warnings appearing frequently.
- Apps lagging or freezing before the phone switches off.
