Review: HTC SMT-5800
The 5800's screen is a decent size and offers 240 x 320 QVGA resolution. When indoors or darker environments, it was very easy to see and the brightness can be adjusted to suit your tastes for visibility and battery life. Colors looked good and most images were sharp. Visibility suffered a lot when outdoors in sunlight. The 5800 had to be held at an angle in order to read the screen.

The 5800 did an excellent job of holding onto a signal. Most times, it had four out of four bars. It doesn't have separate EV-DO and 1xRTT coverage indicators, but it does let you know which service you are getting in the status bar. In the NJ version of the vault test, the 5800 did not drop a call even when it dropped to zero bars of coverage.
Call quality was crystal clear with the 5800. We didn't experience any interference of any sort while using it. Earpiece volume left a bit to be desired, though. With the volume all the way up, it was audible in coffee shops, but it was hard to hear callers when walking on a busy city street. Same goes for ringer volume. Volume in Bluetooth headsets was better. Sound quality of the speakerphone was good for most uses, but it wasn't loud enough to hear clearly from another room. During music playback, the speaker crackled and popped a bit, even with the volume set to just 50%.
Battery life on the 5800 was good. We were able to consistently get through 3.5 days with it even with moderate talking and Web surfing. As always, using Bluetooth to stream music to stereo headsets drained battery life noticeably. With a full charge, we killed off the battery in one day with heavy stereo Bluetooth music streaming. But for the most part, 3 days was a minimum. You can get away with traveling for a weekend without bringing your charger, unless you plan to use it to listen to music for several hours.
