It is probably the difference between passive vs active scanning.  To
save time and consequently power, most battery powered wifi devices
use active scanning where the station sends a probe request and
expects to get a probe response from the AP (or beaconing device).

Typical dwell times in active scanning are 20-40ms / channel while
passive (listen only) scans are usually more like 110 ms / channel,
since the default beacon interval of many APs is 100ms.

If you have linux on your laptop, you might try 'iw wlan0 scan freq
$FREQ passive'
