Everyone always says that using bluetooth etc can be a major drain on your battery power. I want to know EXACTLY how much of a drain on battery power using bluetooth is. If the iPhone were to be subjected to constant bluetooth data exchange for, lets say, 1 hour, how much of an affect would this have on power. any response is helpful! But I'm really looking for hard facts and figures if anyone has any! Thanks.
I've personally never had issues with Bluetooth draining my battery an excessive amount. I leave it on all the time and use A2DP streaming for several hours throughout the day. Despite this I still get a full days usage out of my device.
That being said, on the weekends when I'm not using the Bluetooth streaming, I could probably get two days of usage out of a single charge, or pretty close to it.
For me, this seems "normal" compared with previous devices I've owned and my usage patterns.

Apple doesn't publish the data you want, so no one here can provide it.
