We tested the dual-band (CDMA 850/1900; EV-DO Rev. A) HTC Touch Diamond in San Francisco using Verizon service, and call quality was good. We enjoyed clear audio on our end with very little background noise. The only complaints we heard from friends were of some slight echos or hissing, but nothing that ruined the conversation. We also didn't experience any dropped calls during our testing. Speakerphone quality was a little tinny. We were able to pair the smartphone with the Logitech Mobile Traveller Bluetooth headset and the Motorola S9 Bluetooth Active Headphones.

As we mentioned in the Features section, the RAM size does have an effect on general performance. The Touch Diamond could be quite sluggish, tripping over simple things like navigating the TouchFlo interface, viewing missed calls, or creating a new e-mail message. There was also one occasion where the smartphone kept exiting out of Outlook when we were simply trying to open an e-mail. While we never experienced any major crashes or reboots during our review period, the delays got to be frustrating and more noticeable than other smartphones we've tested.

The one bright spot was the GPS capabilities. Using VZ Navigator, the smartphone was able to find our location in less than a minute, and it did a good job of tracking our position as we moved throughout San Francisco. The application was also able to give us traffic data and provide us with other useful information, such as the weather forecast and movie times based on our location.

The picture quality of the Touch Diamond's 3.2-megapixel camera was OK. Images were clear, but we would have liked a little more richness in color. Also, it was a bit of a challenge to get a steady shot, since there's no dedicated capture button on the side of the phone. Video quality was quite blurry, even when we were doing slow pans of a landscape scene.

Picture quality was mediocre.

The HTC Touch Diamond's 1340mAh lithium ion battery has a rated talk time of 5 hours and up to 15 days of standby time. We are still conducting our battery drain tests but will update this section as soon as we have final results. According to FCC radiation tests, the Touch Diamond has a digital SAR rating of 0.853 watt per kilogram.
