7.	On the home screen on the device, select music, select albums, and then select the album that you ripped in step 3. Select play all, and then press the Zune pad up or down to set the volume to 8.
8.	Set the hold switch on the Zune device to locked, and then note the time. This is your start time.
9.	When you notice that playback of the album stops, set the hold switch to unlocked to make sure that playback has stopped and that the battery has drained. Note the time. This is your end time.

When you follow these steps, the maximum possible battery life depends on the device:

•	Zune 4GB ot Zune 8GB: 24 hours
