I'm looking at the Mophie Air and a few lower-priced competitors and had a couple questions for the group.
1. Any specific brands you like or dislike?
2. What's the best way to use them, with respect to longevity of the iPhone's built-in battery? I've been told to charge both full, then try to drain the external battery first. Does that seem right?
3. Any other words of wisdom on this topic? ;-)
