I ran across this when I first got the Charge in June. The GB update last week put everything back, so I had to re-do it. Only issue is the "Audio Tuning" feature no longer works, so I can't disable the Shutdown and Startup sounds. I ran across mention of and app called Silent Boot and it works on the Startup sound, but not the Shutdown, not a big deal.
My biggest issue was the Battery Full notification. Even with the phone OFF, or in Silent mode, I would get a vibrate when the battery reached 100%. Since the phone is on the nightstand, and I'm a light sleeper, I was really happy to find this work-around.
