Smart Actions arent just about saving battery life, though. You can create different profiles (Work, Home, Workout, and so on) and set rules for each scenario. If you dont want your phone to ring out loud when youre at work, for instance, you can set a rule called Quiet Location to make your phone enter silent mode automatically during work hours. Overall, Smart Actions is an easy-to-use, clever app. Although youll have to spend a bit of time setting up the rules for each profile, Smart Actions will make all the adjustments for you once you're finished.

A 1.5GHz dual-core Qualcomm Snapdragon processor powers the Atrix HD. Thats the same processor we've seen in the HTC One X and the , both of which achieved high scores in our benchmarks. I ran Qualcomms Vellamo app to assess the speed of the Atrix HD; on Vellamo, the Atrix HD earned an impressive score of 2289, landing just above the HTC One X. Well be posting more benchmarks as soon as the Atrix HD completes testing.

However, the real test of a phones performance is how it handles apps and video. I tried a few graphics-heavy games, including World of Goo and Osmos HD. The games ran smoothly, and looked great on the Atrix HDs display. I never encountered any stuttering or freezing with the Atrix HD, but one native app, the camera, crashed once: When I tried to switch from still to video, the app froze up and then closed. What if I had been trying to capture a once-in-a-lifetime moment, and that happened? Not good--let's hope that this incident was just a fluke.

Call quality in San Francisco over AT&Ts network was very good. My friends sounded clear on the other end of the line. When I stood on a bustling corner of the city, my contacts reported that they couldnt hear any of the chatter and noise around me.
