Bluetooth speakers

[stevo8523]

Does anyone know if Bluetooth connected speakers drains the battery faster than connecting to the headphone jack?

I don't like to ever say something for sure when I haven't tried it myself but yes so far as I can tell it will drain your battery faster. This is because Bluetooth is quite a power hungry hardware due to all the information it picks up and sends out, especially of you're sending high quality songs through it.

Yes, that is going to be nice. Though we need more Bluetooth 4.0 devices on the market to make a real impact. Earphones, however, are not likely to benefit from this protocol.

Note that the lower power consumption is not achieved by the nature of the active radio transport, but by the design of the protocol to allow low duty cycles, and the use cases envisaged. A Bluetooth low energy device used for continuous data transfer would not have a lower power consumption than a comparable Bluetooth device transmitting the same amount of data. It would likely use more power, since the protocol is optimised for small bursts. -- Wikipedia

But it should consume less power when the headphones are not actually being used, meaning that the standby time (bluetooth turned on but not used) should be much less power hungry.

A couple other articles I read said that a set of earphones that you can hear from 10 ft away (the teenager walking by) consume roughly 12mW. That's a pretty hard target to hit with any radio transmitting device.


By the way, I didn't know most of this when I started writing my post. Thanks for giving me this little push towards some fun research.

Any bluetooth speaker is needed to be connected via bluetooth. As bluetooth is on and its a power consuming device so i think it will drain power. Earphone aren't needed to be connected through Bluetoth but the headphone port. So they also consume power but the amount is less than the bluetooth.

I've had Bluetooth turned on continuously for almost 2 years on my iPhone to connect to my Apple Watch and haven't noticed any significant battery drain.
When using Bluetooth speakers or headphones, all that is being transmitted is the audio signal. The power to actually run the speakers or headphones is supplied by the batteries in the Bluetooth devices.

Hello and welcome to the forum - you've replied to nearly a 5 year-old thread, so much has changed, especially since Apple is now eliminating the headphone jack (and the 'lightning to headphone jack adapter' does not have great reviews on the Apple website) - as to the first statement above, I've had 3 sets of travel bluetooth speakers and all have a 3.5 mm stereo audio input port, so can be used w/o the wireless BT connection - plus the cabled sound might be better (have not tested); and as to iPad battery use the cabled option should provide much longer runtime - I suspect the BT speaker's battery will be exhausted first.

Thanks Dave.
You have explained it nicely. Actually I joined here newly.
Searching foe buetooth speakers and headphones, this came to my search. And it helped me to decide.

You are right, most of the speakers now came up with 3.5mm jack and if you don't want to lose extra power than cable is better option.
Its actually depends on individual how they like to use, isn't it?
