Hello, There is only one GPS antenna in the iPhone. It is either active and draining the battery, or it is not active, and therefore not drawing power. No matter how many GPS apps are running, the GPS antenna will draw the same amount of power. That said, more GPS (or other apps for that matter) running means more cycles of the processor and more power drain above that of the GPS antenna. Furthermore, GPS apps running guided GPS navigation (turn-by-turn) in the background drain more power than when they are the primary open app.
A friend set up widgets on his Android phone and found that the widgets drained the phone's battery quite rapidly, and caused major slowdown/lag on his android phone. He acquired an iPhone 5 a few weeks ago and jailbroke the iPhone. He then installed the same widgets he was running on his Android phone. Today, he told me the results. He experienced the same extreme battery drain and lag/slowdown on the iPhone 5 that he experienced on the Android phone. It should be noted that this friend is sighted. He considers himself to be a power-user of mobile technology. He also told me that Apple apparently knows what it is doing in not allowing widgets on standard iPhones.
