The one area where non-U.S. support hurts the HTC Touch HD is connectivity. Operating on Europe's 900/2100Mhz HSDPA/WCDMA bands, the smartphone doesn't work with either of AT&T (850/1900MHz) or T-Mobile's (1700/2100MHz) 3G network, so you'll be surfing on EDGE speeds. The good news is that there is integrated Wi-Fi, so you're not limited to just EDGE.
As far as phone features, the quad-band Touch HD offers world roaming, a speakerphone, voice dialing and commands, speed dial, and text and multimedia messaging. The address book is only limited by the available memory (the SIM card holds an additional 250 contacts) and you can store multiple numbers for a single entry, as well as home and work addresses, e-mail, IM screen name, birthday, spouse's name, and more. For caller ID purposes, you can pair a contact with a photo, a caller group, or a customized ring tone. The smartphone also has Bluetooth 2.0 that supports mono and stereo Bluetooth headsets, hands-free kits, file sharing, dial-up networking, and more.
The Touch HD has an integrated GPS and comes with a utility called QuickGPS that is supposed to speed up the time it takes to find your position by downloading the latest satellite information via an Internet connection. For real-time navigation with voice-guided directions, you'll need to add a location-based service like TeleNav GPS Navigator, but you can also use Google Maps for Mobile for positioning and text-based navigation, traffic data, and more. The smartphone should come with Google Maps on the device, though this wasn't the case with our review unit. Not a big deal, however, since it's just a simple, free download to the phone.
With its large display, the HTC Touch HD would seemingly be a good candidate for multimedia functions, particularly video. However, it doesn't quite achieve its full potential in that department due to spotty video playback (more on this in the Performance section). The smartphone supports multiple file formats, including MP3, WMA, AAC/AAC+/eAAC+, WMV, and MPEG-4. The multimedia player is the standard Windows Media player with support for album art (if available), shuffle, repeat, on-the-fly playlist creation, and full-screen video. There are also a handful of extras on the smartphone, including an Audio Booster utility, an MP3 Trimmer program that lets you cut and trim MP3 files and make them into ringtones, and the aforementioned YouTube app.
The Touch HD also comes equipped with a 5-megapixel camera with video-recording capabilities. The camera includes other shooting modes as well, including a cool panorama option that lets you take three consecutive pictures and then stitches them together into a panorama shot. Unfortunately, the camera doesn't have a flash, though there are white balance and brightness controls. For still images, you can choose from six resolutions and four quality settings. Video can be recorded in either H.263 or MPEG4 format in one of four resolutions.
We weren't very impressed with the picture quality. It was difficult to get a clean shot indoors. Even after adjusting the white balance and backlighting, there was still a hazy and orange look to images. Outdoor pictures were slightly better, but bright sunshine proved to be a challenge. We also missed having a dedicated capture key on the exterior of the phone. The Touch HD only includes an onscreen button, which is fine, but requires a bit of a steady hand. Recorded video clips weren't terribly sharp, either, and were a bit choppy. All in all, disappointing for a 5-megapixel camera.
Once done with your photos and videos, you can save them to a contact, as your background image, share them with friends and family via e-mail or multimedia message, or simply enjoy them in a slide show. Compared to some of the other smartphones available, the HTC Touch HD has a rather paltry amount of built-in memory (512MB ROM/288MB RAM), but it does have a microSD expansion slots and ships with an 8GB card.
We tested the quad-band (GSM 850/900/1800/1900; HSDPA 900/2100MHz) HTC Touch HD in San Francisco using AT&T service, and call quality was decent. On our end, sound was mostly clear; there were a couple of occasions when the audio broke up or was crackly, but we never experienced any dropped calls. We were also able to use an airline's voice-automated response system with no problem. Meanwhile, friends reported good results with no major complaints, but they did say the volume dropped somewhat when we activated the speakerphone. Speakerphone conversations on our side were loud and clear. We successfully paired the Touch HD with the Logitech Mobile Traveller Bluetooth headset and the Motorola S9 Bluetooth Active Headphones.
The Touch HD is equipped with a 528MHz Qualcomm MSM7201A processor, but the smartphone felt underpowered at times. We experienced some lag and hiccups as we navigated through the TouchFlo menu and launched applications, most notably with the camera and photo gallery. As we noted in the Features section, the smartphone also had problems with video playback. We checked out a high-definition 720p WMV clip, and the Touch HD simply couldn't handle it. The picture would come in spurts and audio was also broken up. In addition, the video wouldn't expand to full-screen mode. A 320x240 clip fared much better, with smooth playback and synchronized media, and YouTube videos were watchable, though they took forever to load. All that said, for a product with HD in its name, you'd think the smartphone would be optimized for this sort of thing, but not so much.
The smartphone's GPS receiver took its sweet time finding our location the first time we used it, but thankfully, subsequent starts were faster. Using Google Maps, we plotted a course from the Marina District of San Francisco to CNET's downtown headquarters. The list of text-based directions was accurate, but we found that the Touch HD's GPS was about a half-block behind us in real-time tracking.
The Touch HD comes with a 1,350mAh lithium ion battery with a rated talk time of 8 hours and up to 18 days of standby time. We were able to get 9.5 hours of talk time from the smartphone in our battery drain tests. The smartphone has a digital SAR rating of 0.72 watt per kilogram.
