We are trying to setup Shared iPads for one of our departments. However, devices will timeout back to the Lock Screen after 2 minutes and we cannot locate the ability to change this to 1 hour.
I've attempted everything I can think of at this time or have found online and no matter what, the devices will go back to the login screen after 2 minutes. As these iPads will sit on screens that need to be referenced without interaction for several minutes at a time, this has created an issue where the devices are not functional for their intended purpose.
Here are notes from an Apple Enterprise case I opened two years ago:
ISSUE: Shared iPad for Business Temporary Session
STATUS: Product Engineering confirmed that it is expected behavior that the session timer be reset when waking a device. When the device is on battery and not used while in Temporary Session the device will sleep after 120 seconds to conserve battery life. The documented higher values will still timeout if device is plugged into power and it does not sleep after inactivity.
PATH FORWARD: Use a timeout value of 120 seconds or less if devices will be used on battery power and automatic session timeout is desired.
