It was an issue.
4 to 5 hours was typical and Garmin's battery save feature simply turned off the display. Who rides around with their GPS display off? How do you know your heart rate while climbing? It was dumb. As an aside, Rainmaker called it a "nifty feature."
Anyway, a firmware update may have corrected this issue. A friend of mine has one and I asked specifically about battery life. He said he has no problem and that he has run it as long as 9 to 10 hours without a problem. His was purchased more recently and he says his firmware is the latest.
