iPhone 5S tethering

Quick question: Is it more battery efficient to tether your iPhone to say an iPad over Wifi (1 device) or Bluetooth 4.0?

Thanks and a source could be appreciated.

Edit: for both devices

Bluetooth probably uses a little bit less juice but connection speeds will be slower too.

It seems that bluetooth 4.0 is fast enough and uses less battery than wifi.

I'm a bit confused about the tethering that you're talking about. The BT option is pretty straightforward, but WiFi? Do you mean enabling tethering on another device (e.g. iPad) and have the iPhone connect to that for it's data?

To answer your question, I agree with previous posters that BT (4.0) probably uses less battery. How much less? No idea.

I would suggest use WiFi.

I just tried on my iPhone 5S and I got 90kb/s downloading from apple using Bluetooth pairing.
Using WiFi sharing I got 3MB/s.

I used a MacBook Air 2013.
