As we said earlier, the Rizr doesn't offer any feature surprises, but it remains a satisfying choice for a midrange phone. First, however, we'll present the basics. Each contact in the Krzr's Phone Book holds six phone numbers, three e-mails, a Web site URL, three street addresses, a nickname, and a birthday (the SIM card holds an additional 250 names). You can organize contacts into groups, or pair them with a photo or one of 34 (24-chord) polyphonic ringtones for caller ID. Other essentials include a vibrate mode, a voice recorder, text and multimedia messaging, an alarm clock, a calendar, and a calculator. On the higher end, there is a speakerphone, voice dialing and commands, USB 1.1 connectivity, an integrated Google Mobile application, POP3 and IMAP4 e-mail, full Bluetooth, and PC syncing. Bluetooth is onboard as well, but its options are limited. At 23MB, the onboard usable memory is a bit skimpy, but a microSD card slot gives you more room for cards up to a 1GB. On the downside, the card slot is located behind the battery cover, which is tricky to pry off.
Like the GSM Krzr K1 (but not the CDMA Krzr K1m), the Rizr has a 2-megapixel camera. You can take MPEG4 pictures in four sizes (2 megapixel, 1.3 megapixel, 640x80 pixels, and 320x240 pixels), and another innovation offers you a selection of three quality settings. Other features include a multishot option, an adjustable exposure setting, a self-timer, six color effects, five lighting choices, an 8x zoom, and five shutter sounds (plus a silent option).The camcorder shoots MPEG4 clips in two resolutions (176x144 pixels and 128x96 pixels) with sound; editing options are similar to the still camera. Videos meant for multimedia messages are capped at six seconds; otherwise you can shoot for as long as the available memory permits. Image quality was poor for a 2-megapixel camera. Images were bit blurry, and colors weren't always sharp. Also, shots were too dark.
You can personalize the Rizr with a variety of wallpaper, screensavers, menu styles, and color skins. If you want more options or more ringtones, you always can download them via the WAP 2.0 wireless Web browser. Gamers get two Java (J2ME) titles: BlockBreaker Deluxe and Platinum Sudoku. The Rizr also offers a digital music player that plays AAC, AAC+, and MP3 files.
We tested the quad-band (GSM 850/900/1800/1900; EDGE) world phone in San Francisco using T-Mobile service. Call quality was on par with the GSM Krzr K1, voices sounded natural, and there was no background hiss or static. Even better, the volume level was much better than on the Razr. Callers said we sounded fine, and they couldn't always tell we were using a cell phone. Speakerphone calls weren't as satisfactory; voice quality was somewhat muffled with a slight echoed effect. On the other hand, Bluetooth calls sounded better.
The Motorola Rizr has a rated battery life of 6.6 hours talk time and 14.6 days standby time. In our tests, we got a very respectable 6.5 hours of talk time. According to FCC radiation tests, the Rizr has a digital SAR rating of 1.02 watts per kilogram.
