Anyone else's Samsung Focus started syncing on it's own?

As in, when it's not plugged in. Mine has taken to syncing wirelessly as soon as I get home. It's supposed to wait until it's been plugged in for 10 minutes before it syncs. I don't really mind, but it seems strange when a lot of the WP7 forums are full of people complaining that they can't get theirs to wirelessly sync at all.
