My Teric also required two visits to the repair shop before it started working correctly over time. They fixed it up for free and got it back to me quickly. It's been working great now for about 10 months while being used multiple times most weeks. It does not loose charge when not being used, and I never disable the compass. After we week or so the battery is right where I last saw it.
Based on some more reading and anecdotes on proper care, I have recently stopped charging it after every dive day. The computer probably consumes about 10% of the battery after a couple of dives using the compass full time. I now only charge it once the battery is in the 50-75% range, after two or three days of diving.
