"Use wireless networks"/GPS
One thing I absolutely want to work on my phone is my weather app using geolocation to determine my location and give me the current locations weather. I really enjoy this feature, and I know the app only accesses the GPS for a quick second every so often to determine location. I do want my battery to be really good as well though. If I leave on "Use wireless networks" does this automatically turn my Wifi on? I know that kills the battery quick. Or will it just turn it on for a brief second when needed to determine my location?
Thanks in advance
