Wireless Internet is without doubt one of the biggest causes for the battery of your phone or tablet to drop like a stone in water.
The problem here is that the feature is either turned on or off, and that there is no way to automatically switch its state depending on whether it is needed or not.
If you forget to turn of WiFi before you get, you may end up with a phone that is out of battery or nearly there, not great if you need your phone and have to leave early.
There are ways to automatically turn WiFi on or off, and they all come in forms of apps that you can install on your device. Clever Connectivity for Android can turn WiFi off if the screen is turned off for a set amount of time, or if no wireless networks are available.
WiFi Auto-Off offers a similar feature set more or less. It is a lightweight application that provides you with access to three features that you can enable or disable individually on its preferences screen:
- Turn WiFi on when the device gets unlocked.
- Turn WiFi off when the screen is off for at least 10 minutes.
- Turn WiFi off when the phone or tablet is not connected to any network for at least 1 minute.
You can modify the interval for both turn off options. 10 minutes is a long time for instance before WiFi gets turned off when the screen is turned off. Just tap on the preference that you want to modify and it will be turned off at first. Tap on it again and you get the option to change the interval before the wireless connection is being turned off.
The application runs silently in the background after you have installed it. You will notice that WiFi will be activated when you unlock the device, and that it will be turned off again when those criteria are met.
Note that you may not want to turn off WiFi automatically if you are using apps that require it to run. If you need new email notifications for example, you may want to keep it turned on as you won't get any if WiFi is the only source of Internet access.
If you want WiFi turned off automatically then this application does that for you. It prevents you from forgetting to turn it off manually, and in doing so saves power so that you can use the phone or tablet for a longer period of time without having to charge it.
