That a mobile turns off by itself and without prior notice, either when you are using it or simply when the screen is off, is a clear sign that something is wrong with it. However, it is not necessarily an indication that you should throw it away and buy another one, since the problem that may be presenting would have a solution, and here we give you some.
This time we go with 7 possible solutions that you can apply to your mobile if it turns off by itself. These are among the most effective, so they should put an end to the inconvenience that your phone has.
Update the mobile
It is possible that your mobile has received a buggy update. This happens mainly with beta updates, which can present problems in many cases, something that is usually warned by the manufacturers themselves when they are released. However, it also happens with updates that are supposed to be stable and final, and that should not have malfunctions. If this is the case, what you should do is check if there is an update available to download and install. To do this, the following must be done:
- On your Android mobile, go to the settings or the configuration section, which is usually identified with a gear icon on the main screen, the application drawer or after displaying the notification bar.
- Then look for the updates section and check if any are available at the time; In general, there is a button that allows you to check it, although in some mobiles the verification is done automatically.
- If there is an update ready to download and install, proceeds to start the phone update process. Of course, it has no less than 20% battery since, depending on its size, it can take several minutes to complete.
If the mobile shutdown problem was the fault of a firmware version, with the new update installed it should disappear.
Uninstall suspicious apps
Your mobile may turn off by itself thanks to an application with a code error itself or one that has some malicious program that goes unnoticed and is the cause of said evil. In case you have recently installed it, it might be easy to spot which one to uninstall. If you have no idea what it could be, try uninstalling apps you don't use or are less important to you; In this way, you are ruling out which one could be causing the phone to turn off by itself.
Likewise, Uninstall apps that you have downloaded as APK files from dubious app repositories. It is always advisable to install applications only and exclusively from the Google Play Store, since these are more secure and reliable.
Disable auto power off
It is possible that the automatic shutdown is activated and, for whatever reason, you did not realize it. This function is present in any Android mobile and, as its name indicates, it causes the phone to turn off at a certain time and date, or repeatedly, which must be pre-established.
This function is located in the mobile settings, in the configuration section. However, depending on the phone, as well as the Android version and the customization layer, it may be slightly out of position.
In Xiaomi's MIUI, for example, just write "scheduled on/off" in the search bar of the mobile settings. This function can also be accessed through the system app called "Security", which is located on the main screen; in this you must click on the Battery section, and then choose the Battery tab again and, finally, configure the time the mobile is turned on and off, or deactivate it completely.
Do a battery calibration
It does not hurt to calibrate the battery to determine or rule out if the problem is in it. For it, the mobile must be allowed to completely exhaust itself until it turns off on its own. Then it must be charged again -preferably off- until it reaches 100%, but first it must be left without charging, or anything, for four hours. Already after fully charged, the battery would have been properly calibrated, which will improve its performance and further extend battery life.
Avoid extreme temperatures
Extreme heat and cold are the worst enemies of cell phones, as well as virtually any other electronic device. And it is that very low or high temperatures can affect its operation, causing it to turn off by itself. Therefore, avoid using the phone or having it turned on when hot and cold conditions exceed normal.
An overheated phone can not only be caused by a very sunny or summer day. It can also be caused by excessive and prolonged use of applications and games that are very demanding in terms of resources and processing. And, if you add to the latter that it is very hot, then things are worse.
Format or reset the mobile
No one wants to get to this point, of course, because formatting or resetting the mobile means that all data, information, applications, photos, music, files and everything stored on it, as well as registered accounts, will be lost. However, if your mobile turns off by itself and it is due to a software problem, it is possible that the error that causes this to happen disappears.
To format or reset the phone You must go to Settings or Configuration. Once there, you should look for the factory reset option, which can be located in different places, depending on the version of Android, the brand of the phone, and the customization layer of the phone. This is usually found at the bottom of the settings section, although on some mobiles it is found in the About phone section. All that remains is to start the formatting process, and that's it.
Take the mobile to repair
If none of the above worked, it is possible that the mobile has a hardware problem that is related to the battery or motherboard of the same, or a defective connector. Therefore, it should be left with a technician specialized in its repair. If possible, the best thing that could be done is to take it to warranty, so that the manufacturer replaces it with a new one or repairs it, failing that.
