Try to swap for a new phone. I have a variety of apps installed, I usb sync/charge all night every night, and have vibrate alerts for all events. I get multiple texts and emails overnight and this has not been a problem for me (Knock on wood). Its a pretty fair assumption to thin that there is just a batch of poorly made phones that were rushed to meet a release date. A new handset might fiz all that for you.
