Hello, everyone We developed an app which using gps service for iOS 4.0+. Once leaved our app such as returned to iPhone home screen or shifted to other app, gps would be updated in every 10 mins at background for our app. At our development phase, the gps arrow could be disappeared just after leaving our app, but what we are encountering now is that in release version(downloaded from AppStore), the arrow is always showing at the status bar! So the battery cost is more faster than expectation. What is the problem? Thanks and best regards.
