I've bought a second hand Garmin Edge 800 for a while ago. So far, I'm nothing but delighted about the device and the battery life. However, since I have to plug it in in order to upload my rides, it usually gets charged when plugged in so my battery level almost never gets under 50-60 percent, sometimes not even so.
That makes me wonder if I'm doing the right thing. About batteries, sometimes I hear that it's better to empty the battery and then fully charge it. What are your opinions about this? Do you do anything to extend your device's battery life? Or do you worry at all?
