GPS Receivers versus Smart Phones

Don't expect a cell phone signal here.
Is your smartphone as accurate as a dedicated GPS unit? Some researchers at Skidmore College tried to answer that a few years ago (note reference to iPhone 4). Their conclustion: "The short analysis is that iPhones are still worse than a dedicated GPS, but not that much worse."

I am using an iPhone 5s, so not the newest, but I have noted that its GPS unit is about as good as my Garmin's . . . except that for geocaching, it is not so good, because geocaches are marked in hours/minutes/decimal minutes, and the built-in GPS reads hours/minutes/seconds.

Now there are decided geocaching apps that work fine, but they require a good cellular data feed, and when you are in a place like the Purgatory River canyon, you end up thinking, "What possesed me to leave the Garmin in the truck and bring just the phone?"

Bottom line: a dedicated GPS receiver does more stuff than a smartphone does. Using GPS sucks batteries dead, but it's a lot easier to swap in two more AA's than to carry a cell phone backup power source (although I have one of those too, solar-powered).

Galen,

It all comes down to that question of "How many gadgets to carry?" The iPhone camera is about as good as my Pentax point-and-shoot, except that it lacks a true optical zoon. But I am thinking that if I want a GPS receiver, I should still carry a dedicated one, even my old Garmin Gecko, which is about like a flip phone in size.
