You should keep your phone out of your pockets most anytime your sitting some where like the office or your car. The phone works hard having to transmit through your body (which is dense) which in turn uses more power. (Remember the dreaded Iphone 4 with its antennae issue if you held it a certain way it would lose almost all bars)

When a cell phone is on its in constant contact with your providers network. The average cell phone will ping the closest tower every 15-25 seconds. You will sometimes notice this delay when you call someones cell right next to you and it will ring on your end but not on theirs for several seconds. That is because their network is first trying to locate the phone where it last saw it and waiting for the response. Because its doing all that work all the time you will sometimes feel your phone getting hot while its deep in your pocket. If your streaming Bluetooth at the same time you're going to kill your battery.

Also if you keep your phone in your pocket it might cause it to roam which will use even more power since its not looking for its native network and must communicate more with the alien network as well as continue to search for towers in its own network.

So the moral of the story is take the phone out and put in the cup holder or somewhere out in the open away from your body and you will not see a terrible loss in battery while streaming.
