Is there an app that can turn off my wifi whenever I put my phone to sleep? To conserve battery, I always have to turn off my wifi before I turn it off, and turn it back on when I unlock it. After a few days of this, it gets pretty annoying. I'm used to the iPod touch where when you sleep it, the wifi automatically turns off to save battery,and when you unlock it, and turns it back on. It would really save me the time. Also I noticed this Wifi sleep policy thing. I don't really understand, can someone elaborate or explain more. Is it that when your not using your wifi for +15 min, it automatically turns off? Do you turn it on manually, or does it do it auto when you starting using wifi programs like browser. Thanks. I don't know if this helps but I'm using a HTC Legend.
