Wi-Fi and your Battery
Ok, so contrary to the beliefs of many people, Wi-Fi IS good for your battery. But this is only true when you do two things: one being that you turn on Wi-Fi. And two being that you TURN OFF data!!! Using Wi-Fi is useless if you don't turn off data. To turn off data, go to the wireless settings and click on Mobile Network and make sure that it is off.
This will ensure that the phone won't be searching for a data connection even though you are connected to Wi-Fi. Anytime you are home and you have Wi-Fi, use it. When you use Wi-Fi on your device, you are saving battery because the phone won't constantly be searching for a signal, but holding onto a stable connection. You don't need to turn it off when it isn't in use, just leave it on. But please try to remember to turn off Wi-Fi when you leave your house, or the phone will begin to search for a Wi-Fi connection, which will, in-turn, deteriorate your battery.
Hope this cleared up any questions about using Wi-Fi with a cell phone,
