The battery not fitting properly is the most frequent reason for automatic phone shutdown. The size or available space of a battery may gradually vary due to wear and use. This causes the battery to become slightly loose and separate from the phone connectors when you shake or shock your phone.
Turn on your phone and gently shake it to verify if this is the issue. Make sure you push the battery side on your hand to apply pressure. The loose battery needs to be fixed if the phone shuts off.
Android device is getting hot
Furthermore, if your Android phone is overheating, that could possibly be the reason for its sporadic shutdowns. The phone will automatically shut off if the temperature reaches the threshold where it could harm the internal parts.
Remove the phone’s case
Battery space can also become loose as a result of a large phone case or one that replaces your phone’s back cover with its own. Use the phone without the case if you are using one of these and check to see whether the issue is resolved.
Power Button Is Stuck
Another possibility is that your phone’s power button is jammed or broken, turning the device off. Check the device’s operation by repeatedly pressing the power button. The button should be easy to press and release, and it should pop out right away. You can use a tweezer or something similar to remove the button if it’s trapped inside.
Viruses and malware removal
It can be a virus that is shutting your phone off automatically if deleting the apps doesn’t work. Avast Free Antivirus for Android should suffice for this purpose despite the fact that there are numerous security programs available for Android. Install the program, and it will automatically search for and remove any viruses that might be the root of the problem.
Factory Reset
The data on your phone will be totally erased if you perform a factory reset. Before doing a factory reset, ensure that all of the crucial data has been backed up. Be careful not to turn the phone off during the reset process as this might also brick the device and render it worthless.
