- Batteries can be charged via the included charger, or by connecting the phone to your computer, it uses the same USB connection to sync the device and to charge the battery, which is very nice. No need to carry a charger and a sync cable.
- I’ve been using the phone actively today, and call quality is superb!
- Battery life is appalling! I do have Bluetooth activated all of the time, and that does drain power. But still, this device has the worst battery life of any device I have used. Not good at all.
- As already noted, I like that the device charges via the sync cable. But, there is no easy way to determine when charging is complete! No light, no indicator, the battery strength indicator is not granular enough to distinguish between partially full and completely full.
- And the biggie! As noted yesterday, the Bluetooth support works well. But, there is one MAJOR implementation flaw. You can pair as many devices as you like, including multiple headsets. But only one can ever be active at any time. What does this mean? I use two headsets continuously, one is a little ear headset and the other is my car. Both are paired with the phone, and so whichever is available should be used. This is how every other Bluetooth device I have used works, including multiple Sony Ericsson phones, the Nokia E62, the Treo 650, Windows devices like the Cingular 8125 and the Treo 700w (meaning that this is not a Windows Mobile limitation), and more. But not the BlackJack. To switch from one headset to the other I have to go to Settings, Communications, Bluetooth, Headset Settings and use the menu to manually select which one to use for connections (SET will appear next to the selected one and an X next to the other). This is a ridiculous and arbitrary limitation, and could be the deal breaker for me. 🙁
More to follow, I am sure.
