A lot of online video libraries (either live stream or on demand) asks to turn on locations to watch their video. I wonder which location method uses up less bandwidth (GPS only, Power saving/Wifi only, or High Accuracy)
Location doesn't use bandwidth, it uses Wifi (power saving) or wifi plus GPS. Well, it uses THEIR bandwidth, but since you're not limited in those, you don't worry about them. (You can use all the GPS bandwidth you can receive - no one cares, since you're receiving only.)
