So having Bluetooth turned on, when you’re not using a Bluetooth device, isn’t going to drain your battery any more than having Wi-Fi on when you’re not accessing the network.

Does Bluetooth consume battery?

Does Bluetooth use power when not connected?
2 Answers. Yes. When the Bluetooth radio is active it not only turns on the receiver (which consumes power) but also periodically transmits to see if any known devices are in range. When paired devices are on and within range, they do communicate occasionally even if not being used, and thus consume some power.
Does Bluetooth use battery iPhone?
Bluetooth being turned on, in and of itself does not drain battery. Battery drain occurs when certain Bluetooth functions are used like transferring data, streaming music or videos, phone calls. The trouble is using data, streaming music or videos, and phone calls without Bluetooth drain the battery as well.
Should you leave Bluetooth on all the time?
