This is what happened to me - I did have the power cord plugged in (forgot to mention that). Prior to the reset, plugging in the cord did nothing. ALSO, Some of my Live Tiles did not update even after the soft reset - I had to do another manual power down/power up to "jump start" my tiles again.
Since I'm not 100% certain that some app didn't lock the phone, I went into "Background Tasks" and DISABLED all background functionality restarted the phone, and then re-enabled only my Battery app and LinkedIn (a suggestion on the 920 forums to save battery life and increase stability). All other apps are Blocked from background running, but many of their Live Tiles are updating (I assume this is because that feature is not technically "background running").
Anything else I may want to try/should be doing for max stability and battery life, WinPhone veterans? I love this thing so far; I'd hate to have to "go back to the dark side". :P
