SleepMode

SleepMode is used for quieting down your device when you sleep.

SleepMode is used for quieting down your device when you sleep. The network connections are disabled but phone calls can still be received. SleepMode activates and deactivates at a predefined time of day. If the device is used during this time period, then SleepMode is automatically deactivated and activated again after the device has been idle long enough.

Note that mobile data can no longer be controlled via 3rd party applications in Android 5.0, and thus the Disable mobile data setting no longer works on Android 5.0. If your intent is only to quiet down your device you should be able to accomplish this with the built-in Interruptions settings.
