If you've just upgraded your Zune 30 to the new firmware, have you found that your battery isn't lasting nearly as long? Zune-Online.com has the answer. Turn on the WiFi, crank up the screen brightness, and turn on the radio until the battery dies. Then fully recharge it (overnight if you have to), and then reboot it by holding up and back at the same time until it resets. After that, you'll be good to go.
