I noticed yesterday that the little location service arrow was on in my status bar...usually this arrow will disappear after a couple minutes. This one stayed there for hours on end...So I went into privacy and one by one turned off all the apps that have permission to use location services. Long story short, I narrowed it down to the "Red Laser" app. (the app captures bar codes and then shows you were you can buy the product scanned on sale and so on) I then investigated further and this app has a new function that will send you a notification if and when you enter a mall or store that has fantastic deals and sales, thus needing to be on 24/7....having location services on 24/7 sucks up a lot of data, does it not? Or does it use only very little amounts of data being constantly on? I would also have to assume this strains the battery and sucks the juice quickly also???
