Why does it do this? Most of the time my laptop just goes to sleep when it gets to 0% power. But sometimes it completely shuts down and I lose my unsaved files.
Is this a problem with my laptop? The battery runs out fast, so I'm not sure if it's related to that.

What's happening is probably either your computer going into sleep mode (rather than hibernation) and then running out of power, which causes things that are just in the working memory and not saved to disk to be lost, or else it's running out of power before it's managed to go into hibernation.
In either case you, go into the "power options" (you can just type that into the start menu) and edit the plan settings for the current plan you're using. Go to "Change advanced power settings" and find the "Battery" settings group. Change the "Critical battery level" and "Low battery level" to a higher value (I believe they default to 5 % and 10 %, try 10 % and 15 % respectively). Then make sure the "Critical battery action" is set to "hibernation". That should help with the problem.
