I guess that my Diamond qualifies as a phone then. Started yesterday morning at 6:40 am (100%). One hour of phone time and miscellaneous small tasks (check weather, turn on to check time, briefly open settings, etc.) since then. The battery still shows 60% remaining, 33 hours later. If the device is used as a phone and the device is not defective, then it performs as a phone - 4+ hours of talk time or a couple of days of moderate phone use (probably more - I will know that tomorrow). Signal strength during this period was 1-3 bars.
