Background check-ins allow Ivanti EPMM to communicate with devices in the background through Ivanti Mobile\@Work . To do this, Ivanti EPMM wakes up Ivanti Mobile\@Work by sending a silent Apple Push Notification service (APNs) message to Ivanti Mobile\@Work by way of the APNs server. Ivanti EPMM uses background check-ins to provide accurate jailbreak detection or policy updates without relying on device location changes, for example. As opposed to relying on location changes, using APNs for background check-ins uses less device battery power while using more predictable update intervals.

The sync interval defined in the sync policy applied to a device determines how often Ivanti EPMM sends a check-in notification for iOS devices.

**Procedure**

1. Go to <font color="#323232">Policies &amp; Configs &gt; Policies</font>.
2. Select the sync policy name.
3. Select **Edit**. The Modify Sync Policy dialog box opens.
4. Set the <font color="#323232">Sync Interval</font> to the preferred number of minutes. The default interval is 240 minutes. If you want to make more frequent checks for certain policy changes or jailbreak indicators, decrease the value. More frequent checks will have a greater effect on device battery life.
5. Select <font color="#323232">Save</font>.
