Subject [jira] [Commented] (CB-509) geolocation.clearWatch doesn't shut the GPS down under iOS
Date Thu, 03 May 2012 00:49:47 GMT

    [ https://issues.apache.org/jira/browse/CB-509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13267064#comment-13267064

Hugo commented on CB-509:
-------------------------

Most likely same root cause, but the same symptoms occur when simply using getCurrentPosition()
to get a single fix. Once the GPS kicks in, the only way to get it to stop is to suspend the
app...unless your app registers for background location updates, in which case your batteries
will be out in ~5hrs (ugh!!).

> Calling navigator.geolocation.clearWatch doesn't shut the GPS down.
> It's no longer possible to manually invoke geolocation.stop() (and thus the corresponding
stopLocation function in CDVLocation), which was a temporary solution with previous phonegap/cordova
versions.
> It's quite a problem because an application using the GPS even for a short amount of
time will completely drain the battery in a few hours.
