Your iPhone battery level won't be affected significantly. I assume you charge nightly. The bluetooth radio on the smart phones draw very little current - maybe depending on the device, anywhere from 1 to 3% of battery per day. I am sure your phone is connected to at least one bluetooth device at any given time of the day (e.g. your car, headphones, smart watch, bluetooth speaker, etc. etc.).

When in range, your phone is always chattering with registered (even unregistered) bluetooth enabled devices ... even when you sleep.

Can you imagine if you m/c had bluetooth and sent a message to your phone while you slept?
