No, it would not hurt anything but your battery. Although, I have mine set at 5 min interval, and it runs smooth. I'm on Sprint and all GPS apps come up very quick now. I have support for my business, so been on the phone a LOT today. Still at 30% and it will last me another hour at least. Battery drain is there, but not unreasonable for the convenience.
It's as efficient as it can be. YMMV, which is why I would like everyone to try it out.
