    Sorry, I did lots of searches and couldn't find the answer to this question.

    I have a 4s and have iOS 5.01 running.

    I just got a car w bluetooth, does it make a huge difference in battery drain if I leave Bluetooth turned on all the time? Thanks!

    No it doesn't for me at least. Battery only seems to drain a little bit faster when it is actually connected to my car.

    Really only way to know is to try it.

    I got 4s 6.01 and I listen to music, through some BT speakers, to sleep and it's active for 60-90 mins but the BT connection is paired on all night 'cuz I don't purposely wake up and turn it off. In the morning I see less than 10% discharge from a full charged phone.
