In the prehistoric beginnings of this blog, when the dinosaurs were still walking among us, we already discussed the dilemma of which type of connection consumes the most battery, the Wi-Fi or the mobile data connection. Assuming that both spend more or less the same, having the Wi-Fi signal always activated is not the most recommended, since this makes the phone constantly search for wireless signals and consequently, the battery runs out before.
To prevent this from happening, it is usually a good idea to turn on the Wi-Fi only when we need it, although we may later forget to disconnect. And wouldn't it be advisable to also be able to deactivate Wi-Fi when the mobile screen is off, or after a certain time of night? In short, here the ideal would be to be able to carry greater control over when the Wi-Fi signal is activated and deactivated, and that is precisely what we can do with applications such as WiFi Automatic or WiFi Auto.

How to control the wifi receiver on Android with WiFi Automatic
WiFi Automatic is a free tool for Android that allows us to create automations of turning on and off the wifi signal on Android devices. The application is really easy to use and offers a wide range of customization so that we can decide, for example, when we want the phone's Wi-Fi receiver to be activated:
- Turn on wifi when unlocking the device.
- Activate Wi-Fi at a certain time of day.
- Turn on the wifi automatically every so often (5 mins, 15 mins, 30 mins, 1 hour, 2 hours etc.) to make scans.
- Activate Wi-Fi while the phone is charging.
- Turn on Wi-Fi when entering certain locations.
When it comes to automatic shutdown, we also found a few interesting options:
- Turn off wifi when screen turns off.
- Disable Wi-Fi when the mobile is not connected to any network.
- Automatically turn off Wi-Fi from a certain time of day.
The truth is that it is a very complete application that can be used a lot.

The second star utility when it comes to managing Wi-Fi networks is Wi-Fi Auto. It is a bit more complex than WiFi Automatic, although it also does not offer several interesting utilities.
- Turn on the wifi when the screen turns on.
- Turn off wifi when screen turns off.
- Activation and deactivation of the Wi-Fi signal by using a button in the application itself.
One of its most interesting details is that it allows us to establish a time limit of a few seconds from when the screen is turned off until the signal is deactivated, to avoid accidental shutdowns.
In addition to that, it also allows you to create scheduled tasks in such a way that we can decide when the Wi-Fi receiver is turned on or off according to the indicated parameters.

According to its developers, this type of application can help us save up to 30% battery, so if we have a smartphone with limited autonomy it can be a most practical and recommended solution.
As a complementary action, it is worth mentioning that some Android phones also have a very interesting system setting that allows us turn on wifi automatically we are always close to high quality networks. This option is found within the general configuration of the device in «Settings -> WiFi -> WiFi Preferences -> Automatically turn on WiFi«.
