How much battery does Find Friends use
Is it true that leaving Find Friends on all the time drains the battery?
Yes, every application that uses location services uses battery and that app is very much about location.
NO - while it does use battery it does not drain it much, usually something else does. If you experience drain unusually high - it is normally something that phone is trying to process, but unable. It can be anything like, for example you set up to fetch mail every 15 minutes, but you are in the area with no data connection. Or you setup to send e-mail to your exchange server, but server is not accessible. I consider turning off apps that you need counterproductive, so choice is yours.
