According to Chitika, which serves up adverts on some 300,000 websites in the US and Canada Apple fanboys cannot get enough of advertising.
Despite the fact that there are fewer iPhones operating, they seem to be hitting a lion's share of the advertising.
Apple's share of the advertising traffic was 62 percent and Android's 38 percent, despite analyst estimates that Android devices now outnumber iOS in North America.
The company tracked roughly 300 million ad impressions hour-by-hour during the first week of May and graphed the results according to which mobile platform the visitor was using -- Google's (GOOG) Android or Apple's (AAPL) iOS.
Most advertising raffic occurred at 10PM, suggesting that the late evening hours are the most popular browsing times for both sets of users.
For iOS users, however, this peak is followed by a sharp seven hour fall-off, suggesting that Apple users tend to go to sleep at night.
However Android users do not stop hitting the advertising until 4:00 and 5:00AM.
This means that Android users are wired insomniacs who get by on a limited amount of sleep, while Apple iOS users are safely tucked up in bed by midnight dreaming of their next upgrade.
