Wifi Connected - Airplane On

This takes battery saving a bit further if you're the type who seldom use your smartphone for cellular calls (not mobile data). It turns on airplane mode but leaves wifi on if it detects wifi is connected. I use this along with another job that reverses the process when there is no wifi, airplane mode off, mobile data on, wifi radio off. Then you could add a wifi job that enables wifi automatically when your within your access point's proximity.
