Does it seem like your battery life is being depleted very quickly, even when the phone screen is turned off? This may be partly due to the fact that the device is remaining connected to a Wi-Fi network even while it’s asleep. This functionality allows the phone to keep your data updated when you turn it back on.
But if you are concerned about the duration of your battery life, then you might be looking for a way to change this behavior. Fortunately there is a setting that will let you disconnect from Wi-Fi when the phone goes asleep, and instead download data over a cellular network. This will cause you to use more cellular data, but it will decrease the amount of battery life that is used.
How to Disable Wi-Fi Connection While Sleeping in Android Marshmallow
The steps in this article were performed on a Samsung Galaxy On5 in the Android Marshmallow operating system. This setting will cause your phone to disconnect from Wi-Fi when the device goes to sleep. While this will save battery life, it will also result in increased data usage, as any data that is downloaded will be done so while the device is connected to a cellular network.
Step 1: Open the Apps folder.
Step 2: Select the Settings app.
Step 3: Choose the Wi-Fi option.
Step 4: Touch the More option at the top-right of the screen.
Step 5: Select the Advanced option.
Step 6: Choose the Keep Wi-Fi on during sleep option.
Step 7: Tap the Never option.
As mentioned previously, this will disconnect you from Wi-Fi while the device is asleep. This will result in increased data usage.
