How much battery drain with bluetooth useage?

[oBMTo]

Thinking about pairing the MBA with a bluetooth mouse and was wondering how much the battery life would suffer from this. If it is significant amount, then I would rather use a USB dongle with a wireless mouse.

it should not be a significant amount since bluetooth 4.0 is designed to consume less power than its predecessors which in my opinion weren't really power hogs to begin with.

Will you get better battery life getting the the web via Bluetooth Tethering to iphone vs WiFi?

USB 4.0? or bluetooth 4.0, it's a typo, isn't it

Would the laptop still have lower power consumption from BT 4.0 regardless of the BT version of the paired device?
