Robert, there is a potential problem with a GPS device that is powered only when the camera is powered. The GPS device will need to acquire the satellites before it can send any data to the camera to be inserted into the EXIF data. The advantage of the pinout, or similar, device is that it uses your phone's GPS which is always on meaning there is no acquisition delay and you can shoot immediately.
I would quite like that functionality but there are other devices that can do what I would like too.
Once at location and in 'shooting mode' I don't usually turn my camera off, except to change lenses or batteries. As JK mentions the camera consumption is minimal as it sleeps. On rare occasions I have left my D3 and the D300s switched on for days or weeks, the battery is still as it was when I left it. Haven't yet done it with the D800 but expect similar result.
I don't trust my iPhone GPS at all, When I try using my Apple 'Photos' software I have noticed the allocated map location can be up to five miles from the actual location and is frequently inaccurate to an unacceptable degree. Unrelated from photography, the compass bearing can take several minutes to stabilise, with wildly varying opinion as to where North is. This translates to initial very poor reliability/performance for my sky/star watcher, locator type apps. I use an oldish iPhone 6S, newer phones may be better? I don't know but unlikely to upgrade for at least two years, so I just get on with it. Perhaps this is related to your comment about satellite acquisition? Perhaps I need to somehow wake the satellite acquisition somehow before taking photos with my iPhone.
