Looks like the current implementation uses the shortest value for that situation: http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=services/java/com/android/server/LocationManagerService.java;h=3f268c933f14fabc0950657b43d7e4df1e463cf8;hb=63abad7ed389aea8eef75786d3628cfb288988dd#l806 Seems like an OK decision there from some quick tests. I called requestLocationUpdates for two listeners. One with a power conserving hint argument of 30 seconds. The other with 60 seconds. Both listeners got the same update frequency. In number of seconds between onLocationChanged calls: 1, 1, 2, 1, 2, 1, 2, 1, 2, 1, 39, 1, 1, 1, 1, 1, 1, 1, 1, 1, 3, 37, ... Corresponding to occasional ~30 second shutdowns. Once I called removeUpdates for the listener that was registered for 30 seconds, then the listener registered for 60 seconds started getting what it would normally get: 2, 1, 69, 1, 1, 3, 1, 2, 1, 2, 1, 2, 1, 70, 1, 1, 2, 1, 2, 1, 2, 1, ... ~60 second shutdowns. End result, the listener that was registered saying it is OK with ~60 second shutdowns never actually has to wait that long if there is another listener registered that wants more frequent updates. Meanwhile the one that wants the most frequent updates gets what it normally would.
