If I run several GPS tracking apps at the same time, like strava, ski tracks, my tracks, for example, does the battery drain much faster then using a single gps tracker? Basically what I'm asking, is how much of the gps battery usage is from the communication to the gps vs how much from the individual app usage.

  • The GPS itself probably won't use much more power – after all it doesn't matter if 1 or 100 apps ask for the location: it's obtained once and then handed to all. Which reduces your question to: "Does using multiple apps use much more battery". The answer to that is "it depends". It certainly uses more – but how much depends on what those apps do, how well they are written, etc. Also think of ads they may draw, or data uploads they might perform. – Izzy Dec 29 '17 at 20:10
  • Perfect, that actually answers my question, I was asking whether the multiple apps would cause the gps to use more power. – user1762507 Dec 29 '17 at 20:15
  • Ah, so I've guessed right. Then let me make that an answer you can accept :) – Izzy Dec 29 '17 at 20:24

The GPS itself probably won't use much more power – after all it doesn't matter if 1 or 100 apps ask for the location: it's obtained once and then handed to all. Actually there's even a "location cache": if you're now at e.g. Trafalgar Square in London, you're unlikely to be in Manhattan the next second (exaggerating a little) – so that's what subsequent requests within a short interval access. And that's also what's used when you e.g. enter a tunnel and temporarily have no location info.

A little more power of course will be required as the device is kept awake "more aggressively": one app probably would update the location once per second (or fewer times) – while multiple apps won't do that "unisono" (at the exact same time). But compared to the overall load while tracking (or navigating), that's most likely rather a little indeed.
