Share your location on a real time map with Facebook Messenger's Live Location2
The new feature will be available for both iOS and Android users. On both platforms, you can stop sharing at anytime, even before the hour is up. On iOS, you can open Live Location by tapping the Location icon, or by tapping the More icon and then selecting Location. Tap the blue bar to start sharing your location. On Android, tap the Location icon, or tap the More icon and then click on Location. Similar to the iOS version, tap the blue bar to start sharing your location.
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.
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.
