Last week, we saw some interesting findings from AdMob about smartphone usage. Now Compete has shared some of its own findings with WebProNews. The firm recently conducted a Smartphone Intelligence Survey.

About 47% of T-Mobile smartphone users use their phones to find local branches and ATMs, while 45% of AT&T users and 36% of Sprint users reported doing this (see chart #1 for data).

According to the survey, 34% of T-Mobile users use their phones to pay bills, followed by AT&T users (31%), Sprint users (23%) and Verizon users (21%).

While the numbers were lower, 19% of T-Mobile smartphone owners used their phones to buy/sell stocks. 11% of AT&T and Verizon users also bought/sold stocks, while only 8% of Sprint users reported buying/selling stocks.

73% of smartphone owners reported using their devices for at least one shopping-related activity during the holiday season.

Currently, 38% of smartphone owners conduct leisure travel research on their mobile devices (at least some of the time), according to the findings. This compares to 27% using mobile for leisure travel bookings, 20% using for business travel research, and 15% using for business travel bookings.

The findings present an interesting look at how people are using their devices to interact with the mobile web and make decisions.
