Condensation inside a dry bag

[snafu]

So I use a small dry bag for my cell phone and car keys when I am out on the yak. I have been having an issue with condensation inside the bag. The phone has condensation on it, and gets all fogged up when I take it out. The point of it is to keep things dry, not make things wet.

What tips or tricks can I do to stop this? Maybe put some of those little white bags that come inside an electronics box? You know, those little bags of beads that say "do not eat". Would that work? Or do I need to upgrade to a dry box?

I don't like the smaller dry bags, I use a dry box and never have any issues. Try and keep the dry bag out of the sun, that may keep the condensation down.
