Ultimate battery life routine

This routine uses wifi as a trigger for turning on/off the cell radio which saves a ton of life when you're disconnected from selected wifi. To make the routine work properly you need to first turn on airplane mode then turn on wifi. This makes your phone remember to keep wifi on when you toggle airplane mode.

Leave home -> cell on Arrive work -> cell off Leave work -> cell on Arrive home -> cell off

This might work for triggering NFC, GPS bluetooth, etc but I haven't tried.
