GPS significant Location change stop after 10~15 days

1. We are using background significant Location change.

2. After termination of the app, the app does not update locate the SLC event between 11-15 days.

3. When the app is restarted, It works fine again, but the app does not update locate after 11 ~ 15 days.

4. There was no crash log during the period when the app stopped working.


And, There is no description of the validity period of the App in the official document.

"If you start this service and your app is so terminated, the system automatically relaunches the app into the background."

Is there a cause for the App's GPS update to stop? Or a bug?


If so, in which case I would like to know if this event is stopped.

device has not into low power mode or does not restart the device.


How long does significant location change work without an app being used?
