title: iOS GPS Battery drain, how to make it less drain?
body: <p>My service needs gps. I actually implemented a service, which turns the gps on, checks if the location is valid, and then goes to sleep for some time. (Starting with 5 seconds, and if no movement is detected, it can sleep up to a minute)
  After that, I start the gps again, and get a new location.</p>
  
  <p>But the battery drain is still high! Ive used locMgr.distanceFilter = 10.0f and desiredAccurady = NearestTenMeters.</p>
  
  <p>How do I minimize battery drain more?</p>
