Description: Performance
We tested the quad-band (GSM 850/900/1800/1900; EDGE; UMTS) Nokia N75 in San Francisco using Cingular service, and call quality was excellent. We had no problems hearing our friends and enjoyed clear, crisp audio with very little background noise. Our callers reported the same and said they couldn't tell we were using a cell phone. The speakerphone was also quite good and had plenty of volume to carry on conversations in noisier environments. In addition, we had no problems pairing the N75 with the Logitech Mobile Traveller Bluetooth headset.

General performance was faster than that of other Nokia N series phones. We didn't experience a long delay when opening and switching between apps, although the camera function slowed things down a bit. Music playback through the phone's dual speakers was actually quite disappointing. While there was plenty of volume, songs sounded tinny and lacked richness. Once again, we also have to point out that the restriction of having to use Nokia's proprietary earbuds (unless you get an adapter) is a big pain. Watching videos on the phone wasn't exactly a treat either. We viewed several clips from the Cingular Video service, including music videos, sports highlights, and news, and some from our personal video library. Though audio and video were synchronized, images were quite pixilated and blurry.

The Nokia N75 is rated for four hours of talk time, and as long as eight days of standby time. In our our battery tests, we got only an appalling two hours of talk time on a single charge. Not only that, but the battery/rear side of the phone also felt very warm. The atrocious talk time battery life may be the result of running on the 3G network, but having to run for the nearest outlet after such a short time is pretty darn bad. For MP3 battery life, we were able to get nine hours of continuous listening time after just one drain test, but we'll update this score as CNET Labs runs the full gamut of performance tests over the next couple of days. According to FCC radiation tests, the N75 has a digital SAR rating of 0.68 watt per kilogram .
