I just figured out why my battery life has been aweful for the past few days.

QGVDial was eating up ~25% of the processor constantly for the past few days. Looking at batterygraph, it appears that it began when I tried to make an outgoing call, and it failed to go through (it took forever trying to get the number to dial, and then gave some sort of error).

I glance at my log file, but didn't see anything that looked very useful. I'm not sure what can be done about this, but just something to keep in mind.
