Help how to auto toggle location services??

[akikhia]

so i found that my battery life improves when i unchecked use mobile networks in location. can somebody tell me if theres an app or something to auto toggle mobile networks when i turn on maps and gps when i turn on navigation??

so i was in the midst of testing this. im getting at least 14 hrs of batt with bluetooth on not connected and network location off vs. 10 hrs of batt with bluetooth off and location services on. what the f*** im confused. i thought bluetooth was my biggest offender. it shows my bluetooth uses 33% of battery life.
anyone have any input??
