Why automatically turn off mobile data
You may be wondering why it is convenient to automatically deactivate mobile data when we connect to Wi-Fi. One of the reasons is to save battery. After all, the mobile will continue to search for networks and will maintain the connection, even if it is not really pulling data when connected to Wi-Fi. This will cause a greater consumption of energy that we can save. The battery is one of the limitations that we always have on our phones, since any application, any service that we have activated is going to consume resources and may run out.
But it is also interesting to know for sure that we are using only Wi-Fi and not mobile data. We could avoid consuming the rate without realizing it if, for example, we start downloading a large file. If we configure it to automatically disconnect, we will know that we are using the wireless network.
Another reason is simply save time. It is common for us to disconnect mobile data manually when we get home, precisely because of the two previous points that we have seen. But if we configure it so that this happens automatically we can save time and not have to always turn it off manually. It will be something that the phone itself will do by itself without us having to interact.
Therefore, these are some reasons to want to automatically disable mobile data on our phone, whenever we connect to a Wi-Fi network. The process, as we are going to explain, is simple. Once you have it configured, it will be automatically disabled whenever you connect to a wireless network, wherever it is.
Steps to remove data when using Wi-Fi
let’s show how to disable mobile data automatically on Android when we connect to Wi-Fi. It is something that you can easily do on your device and thus save battery or prevent it from connecting to the network while browsing at home on Wi-Fi. You can avoid this both when you get home, at work if you have a wireless network, etc.
Enable developer mode
This option is not visible in the mobile settings like others that we do see more accessible. To use it we have to go to the developer options. By default this feature is hidden on mobile, but we can quickly enable it and be able to use it.
To do this you have to go to Settings, About phone, Software information. There you will see an option called Build Number. What you have to do is press seven times repeatedly until the developer mode is activated, which is what we are going to need for our objective.
When you have done it, it will ask you for the security code of the phone to verify that you are the owner of the device and you can go back. This is a security procedure that you will have to perform, something common when you enable something like this on Android.
developer options
Once you have enabled the developer mode, you can go to Settings again and below you will see Developer options. This did not appear before, but after the initial step that we have carried out, you will already have it enabled. However, if this is something that you had already done previously, it would appear.
Within Developer Options, go to the section of Mobile data always on. In some versions it appears as Mobile data activated. What you have to do is disable this feature. This will cause data to be disconnected when you connect to a Wi-Fi network.
You must bear in mind that depending on the version this function may come already deactivated. However, if you have come this far, it is because you want to disable mobile data automatically when you connect to Wi-Fi, so that will mean that in your case this function is activated and you need to deactivate it by following the steps that we have explained. Now, the fact of having it activated means that it will connect faster in case you have to change networks.
Mobile data disabled when using Wi-Fi
From then on, mobile data will be automatically disabled when using a Wi-Fi network. You won’t have to worry about having to manually disable them every time you connect to a wireless network. In this way you will save battery and also avoid certain problems that may arise.
However, at any time you can Reverse the situation. If you want to re-enable this function and that the mobile data remain activated even if you connect to a Wi-Fi, you simply have to go to the Developer Options again, which will already be enabled unless you have changed it, and go to Mobile data always active and check the box.
We have explained how to carry out these steps on Android devices. You should keep in mind that this may vary slightly depending on the exact version you have installed, but the procedure will be similar. Also, if you have iOS you can also configure it in a similar way.
Conclusions
In short, by following these steps that we have indicated you will be able to disable mobile data automatically every time you connect to the Wi-Fi network. It is an option offered by Android although, as you have seen, you will have to enable the developer options so that you can use it.
If you want to save battery power and avoid certain problems, it’s a good idea to turn off mobile data automatically when you connect to a wireless network. Now, you will always be able to configure it again so that they remain active if necessary for any reason.
