I've been trying to figure out how to get the user's location when the app is terminated like how the app Moves does it. The only way I know of doing so is with Significant Location Changes. However with significant location changes, the app only gets woken up either every 500 meters and only if it has been around 5 minutes past the last update.
According to Apple:
Apps can expect a notification as soon as the device moves 500 meters or more from its previous notification. It should not expect notifications more frequently than once every five minutes. If the device is able to retrieve data from the network, the location manager is much more likely to deliver notifications in a timely manner.
In the Moves app, even with the app is terminated, it is able to retrieve the user's location very accurately without having much drainage in battery. It also doesn't seem to have background location turned on as it's reason in the battery usage list only shows "Background Activity". So I'm wondering how an app like Moves is doing this. Any help would be great! Thanks.
