I'm suprised to hear that 5-6 hours is average for typical use. I have the cadence and HRM options as well. Perhaps i should just thank my lucky stars I'm getting such good battery life. A couple of questions:
1. Did they say how long it would take them to repair the unit if you did send it in?
2. What sort of recording interval are you using? I'm using the "Smart recording" option.
3. Is the firmware up to date?
One other observation I will make about the computer is that the speeds and distances reported by the unit are consistently lower than that of my riding partners. I'm not sure if this is because my riding partners have their wheel settings off or if the Garmin's Smart Recording interval has a greater margin of error. I would think that the speed being reported is more accurate than the wheel calculated models but I don't know for sure.
I forgot to ask about their turn around time but I believe that they are fairly fast. They also told me that they could sell me a new one and give me credit when I return the old one which is probably what I would do.
I am not using the smart intervals. That would probably be a good idea and might save some battery life. Also, I mainly entered a while size when I set the device up. Not sure if that was a good idea or not.
Updating the firmware is probably a good idea. I think I did it when the device was new but not sure.
Lastly, I spoke to the people that make the Powerstick. The device will be available in Mid September and will sell for $69.00. The Powerstick puts out 750 Mah and the Garmine 305's battery puts out 800 Mah. So the powerstick will just about double the battery life. Custom length USB cables are available through Powerstick people as well.
