So, I have an HTC holster that I used for the last year. The Droid JUST fits into it. However, I kept having the Droid come on in my holster and it was driving me batty how it would unlock on it's own. Then it hit me. The holster clips shut MAGNETICALLY. The Droid thought it was in a multimedia dock so it stayed on while on my side. THAT's why my battery was draining so fast! So, be sure to get a velcro or other type of holster, nothing with magnets.
