This article was just an example to illustrate some real world numbers.

Even with BLE it can happen, that a device can draw an *average* power
of more than 18 mW and not just 2.5 mW. And "device" is also the
Smartphone of course.

And when BLE is already using 18 mW in some situations, regular
Bluetooth does not need *less* power than this - the reason for BLE was
to *save* power - thus the name "Bluetooth Low Energy".
