Does there exist a tweak or sbsettings addon that automatically turns wifi on/off depending on if you're trying to load a page ? I will try to explain what I mean with an example: You load a long page in safari. It takes you 10 minutes to read the page. The entire time, wifi has been on but not sending any data. You have wasted 1-2% battery just because wifi was turned on during that time. What if there was an app that turned off wifi when a page was finished loading ? Then when you try to load another page it turns wifi on again. It seems simple. No point in having wifi on when its not even being used.
