Why Does My Phone Keep Turning Off By Itself? 6 Fixes Are Here!

Part 1: Possible reasons for phone turning off by itself

Before jumping to fixes, it's important to understand why your Android phone keeps turning off by itself. The cause directly determines the most effective solution. Here are the six most common reasons behind this frustrating issue:

• 1. Incomplete or corrupted software updates: When a system or app update is interrupted mid-process — due to a lost connection, low storage, or a power cut — the incomplete installation can destabilize the OS, causing the phone to shut down repeatedly. Even a partially installed app update can trigger this behavior.
• 2. Incompatible or malicious third-party apps: Apps downloaded from outside the Google Play Store may not be fully compatible with your Android version. These apps can consume excessive RAM, interfere with core system processes, or introduce instability that forces the device to shut off unexpectedly. Adware or spyware apps can exhibit similar behavior.
• 3. Battery degradation or hardware failure: Lithium-ion batteries naturally degrade over time. A battery that has lost significant capacity may report an inaccurate charge level and suddenly cut power when the actual usable capacity is depleted. Physical battery damage — such as swelling — can also cause sudden shutdowns. If your phone is over 2 years old, battery wear is a strong suspect.
• 4. Overheating and thermal protection: Android devices have a built-in thermal protection mechanism. When the processor or battery temperature exceeds a safe threshold — typically around 45–50°C (113–122°F) — the device will automatically shut down to prevent permanent hardware damage. This is more likely during extended gaming, video streaming, or when using the phone while charging in warm environments.
• 5. Physical hardware issues: A damaged or overly tight phone case can apply continuous pressure to the power button, triggering accidental shutdowns. A cracked or loose battery connector can also cause power interruptions. If you notice the issue worsens when pressing the case sides, a physical cause is likely.
• 6. Corrupted system files or OS errors: System file corruption — caused by a failed update, sudden power loss during operation, or malware — can cause Android to crash and restart unexpectedly. This type of issue often requires a deeper fix, such as a system repair tool or factory reset, rather than simple app-level troubleshooting.

Once you've identified the most likely cause based on your situation, you can proceed directly to the corresponding fix below. If you're unsure, start from Part 2 and work through each step systematically.

Part 2: Check the battery status on Android

A failing or degraded battery is one of the most common reasons an Android phone turns off by itself — even when the battery indicator still shows a reasonable charge. Before trying software fixes, it's worth verifying whether your battery is healthy. Android includes a built-in battery diagnostic tool you can access via a hidden service code.

What this test checks: The battery info screen reveals key metrics including battery health status, charge level, voltage, temperature, and charge type. A healthy battery should show a status of "Good." If the status reads "Bad," "Over voltage," "Dead," or "Unknown," battery replacement is strongly recommended.

Step 1: First, open the dialer on your Android phone shown in the screenshot below.

Step 2: Now dial *#*#4636#*#* just like dialing a usual phone number and wait for the "Battery Info" screen to pop up.

Note: Sometimes, the above-mentioned code may not work. In such cases, try dialing *#*#INFO#*#*. The following screen will appear now.

If the battery status shows "Good" and the temperature is within a normal range (20–35°C at rest), your battery is likely not the cause. However, if the voltage reading is unusually low or the health status shows anything other than "Good," consider having your battery professionally tested or replaced. Battery replacement is often the fastest and most cost-effective fix for phones that are 2+ years old and experiencing random shutdowns.

If the battery checks out fine, move on to the following solutions to address software or system-level causes.

Part 3: One-click to fix Android phone keeps turning off

Part 4: Update software to the latest version to fix Android phone keeps turning off

Outdated or buggy software is a surprisingly common — and easily overlooked — reason why an Android phone turns off by itself. Android OS updates and app updates are not just about new features; they regularly include critical bug fixes, memory management improvements, security patches, and stability enhancements that can directly resolve unexpected shutdown behavior.

When your system software is outdated, known bugs that cause crash loops, power management errors, or kernel-level instability may remain unpatched. Similarly, an app running on an outdated version of Android may encounter compatibility issues that force the system to terminate processes abruptly — triggering a shutdown.

How to update your Android software:

1. Go to Settings on your Android phone.
2. Scroll down and tap System (on some devices this may be labeled About Phone or General Management).
3. Tap Software Update or System Update.
4. Select Check for Updates and allow the device to scan for available updates.
5. If an update is available, tap Download and Install. Ensure your battery is above 50% and connect to Wi-Fi before proceeding.

What to do if no update is available: If your device is already on the latest software version but the problem persists, the issue may be related to a specific app rather than the OS itself. Open the Google Play Store, tap your profile icon, go to Manage Apps & Device, and update all pending app updates. Pay particular attention to recently installed apps that may have introduced instability. You can also check how to fix apps crashing on Android for a deeper dive into app-level issues.

Part 5: Cool down your phone to avoid your phone keeps turning off

Overheating is a leading — and often underestimated — cause of random shutdowns on Android phones. Every Android device has a built-in thermal protection system. When the internal temperature of the CPU, GPU, or battery exceeds a critical threshold (typically 45–50°C / 113–122°F), the phone will automatically power off to prevent permanent damage to its internal components. This is a safety feature, not a defect.

Common signs your phone is overheating before shutdown:

• The back of the phone feels unusually hot to the touch
• Performance becomes sluggish or apps start lagging just before the shutdown
• A warning notification such as "Temperature too high" or "Device cooling down" appears
• The phone turns off specifically during charging, gaming, or video streaming

How to prevent your phone from turning off due to overheating:

• Avoid using the phone while charging: This combines two heat sources — charging generates heat, and active usage generates more. Together they can push temperatures beyond safe limits quickly.
• Remove the phone case during intensive tasks: Phone cases, especially thick silicone or leather ones, trap heat. Removing the case temporarily improves passive heat dissipation.
• Place the phone on a hard, flat surface: Fabric surfaces (sofas, beds, pillows) block the ventilation areas on your phone's back, causing heat to build up faster.
• Lower screen brightness and close background apps: Reducing unnecessary processor load lowers heat generation significantly.
• Keep the phone out of direct sunlight and hot car interiors: Ambient heat alone can raise internal temperature above the shutdown threshold in a hot car.
• Avoid running multiple heavy apps simultaneously: Multitasking with graphics-intensive apps pushes CPU and GPU usage to maximum, rapidly increasing internal temperature.

If your phone overheats frequently even during light use, this may indicate a deeper hardware problem — such as a failing battery that generates excessive heat, or a damaged thermal paste layer on the processor. In such cases, a professional repair may be necessary.

Part 6: Narrow down the randomly turning off issue in Safe Mode

If your phone keeps going off randomly and you suspect a third-party app may be responsible, booting into Safe Mode is the most effective way to test this hypothesis. Safe Mode is a diagnostic environment built into Android that loads only the core operating system and pre-installed system apps — all third-party apps you've installed are temporarily disabled.

How Safe Mode helps: If your phone runs stably in Safe Mode without shutting down unexpectedly, it confirms that one or more of your installed third-party apps is causing the issue. If the phone continues to shut off in Safe Mode, the problem is deeper — likely at the OS or hardware level — and you should proceed to Part 7 or revisit Part 3.

Step 1: Long press the power button to see the following options on the screen.

Step 2: Now tap on "Power Off" for about 10 seconds and click "OK" on the message that pops-up as shown below.

Step 3: Once done, the phone will reboot and you will see "Safe Mode" on the main screen.

How to identify and remove the problematic app: After confirming the issue is app-related, reboot your phone normally and start uninstalling recently installed or updated apps one by one. Begin with the most recently added app, reboot after each removal, and observe whether the random shutdowns stop. Battery-draining apps or apps that request unusual system permissions are prime suspects. Once you've identified the culprit, uninstall it permanently and consider reporting it via the Google Play Store.

Part 7: Back up your data and perform a factory reset

Note: You must take a back-up of all your data because once you perform a factory reset on your device, all media, contents, data, and other files are wiped out, including your device settings.

A factory reset is the most comprehensive software-level fix available when an Android phone keeps turning off by itself and all other methods have failed. It restores your device to its original out-of-box state, eliminating any software corruption, problematic app configurations, or OS-level errors that may be causing the random shutdowns. While it is a drastic step, it is highly effective when the issue is rooted in software rather than hardware.

Before performing a factory reset, back up your data. A factory reset will permanently erase everything on your device — contacts, photos, videos, app data, downloaded files, and all personal settings. Without a backup, this data cannot be recovered.

Wondershare Dr.Fone is a great way to back up all your data to prevent it from getting lost after resetting the phone. It works brilliantly as it backs up all data and allows users to retrieve it fully or selectively. You can backup all files from your Android to PC in just a click and restore them later.
