There is one downside: by using this patch, you lose easy access to your USB port. Most of the time, I've found this to be a non-issue. I do almost all my charging at home, and I have wireless charging pads placed strategically around my house—no cables necessary. And since Google stole my headphone jack, I finally bit the bullet and bought some Bluetooth earbuds, so I don't need the port for listening to music, either. If I'm going on a long drive or a vacation where I know I'll be charging by cable, I just leave the Magic Tag at home. Most of the time, though, it stays on.
