AdMob has released its Mobile Metrics report for April, which compares market share of smartphones by operating system to market share of mobile web and application usage. The report also compares smartphone browsing of mobile web sites to smartphone browsing of HTML sites.

The firm determined that smartphones accounted for nearly 3 times more usage than their relative market share. With regards to usage of mobile sites and HTML sites on mobile devices, AdMob found relative usage of both to be highest on Apple and Android devices. 

"The emergence of devices such as the iPhone and HTC Dream (G1) that deliver truly compelling Internet experiences has generated discussion of which Web consumers will use on mobile – mobile Web sites or HTML sites," says AdMob.

Other interesting findings from the report include:

- The iPhone OS had 8% of the smartphone market, but generated 43% of mobile Web requests and 65 percent of HTML usage.

- The Android OS share of the smartphone market was less than 1%, but generated 3% of mobile Web requests and 9% of HTML usage.

- The Symbian OS had 52% of the smartphone market, but generated only 36% of mobile Web usage and 7% of HTML usage. 

- Usage of mobile Web sites greatly out paces usage of HTML sites on smartphones running the Symbian and RIM Operating System (OS).

- 24% of US requests were made over a Wi-Fi network. The top five Wi-Fi devices in terms of usage were the iPhone, iPod touch, Sony PSP, HTC Dream (G1), and HTC Dash.

AdMob's report relied on research from Gartner and ad requests from its own network of mobile websites and apps, which include 7,000 sites and 1,600 apps.
