Windows Phone Thoughts: Charging Up - How Often Do You Do It?

Whenever a new device comes out, one of the issues that we all talk about and debate is the battery life. Sometimes devices with exceptional battery life are deemed unacceptable because of other features, but in general the battery life seems to be something we value in our devices (And for good reason!). But how often do we really use all that battery life? I've used an iPAQ 6315 for many months now, and have only gotten close to it being at less than 10% power once. I normally charge nightly as I sleep, and I believe most users probably cradle their devices at least once a day for an extended length of time.

So fellow PPCT'ers, how often do you charge? How often do you wear down that battery to critical levels? And if you don't get it down to a critical level, do you think the battery capacity should be as important an issue with a device as it sometimes is?
