Depend on which 3rd party, and how many 3rd party app and music installed.
I have no issue with few I used, At Bat, CRNT, Dark Sky, Drip, Event Countdown, Motion-X (love it, use daily), Just Press Record, Parkit, Reminder Nano, TripCase, Warriors (Oh, yes, undefeated!), Webex, Wink.
I highly recommand don't setup to install all AW app from iPhone when initial pairing. Install no 3rd party app when initial pairing than add only one you will use. Remember, you are likely going to have iPhone with you almost all the time, so there is no need to install any 3rd party AW app, just because you think you might need it but never use it.
