Share your location on a real time map with Facebook Messenger's Live Location
Live Location will allow you to share your position on a map in real time, for up to 60 minutes
Both iOS and Android versions countdown your 60 minutes thanks to a clock in the lower right of the screen. On iOS, users can see how long it will take for them to get to other peoples' locations by car.
"We’ve been testing this for a little while, and people tell us that Live Location is helpful when trying to coordinate with friends, telling people how close you are when you’re on your way to an appointment, or even sharing where you are with your roommate when you’re on your way home at night. You can share your Live Location with a group of friends in Messenger or just with one person — it’s up to you!"-Facebook
If you're concerned about how this will affect your battery life, Facebook says that the feature consumes a standard amount of power and won't quickly zap all of the energy inside your phone's juicer.
