Title: eTrex 20 battery use pattern
Post by: vorsprung on 31 March, 2013, 05:41:41 pm

I think I've discovered an eTrex 20 bug/feature/issue/problem which is worth bearing in mind

If you leave the eTrex 20 plugged into a computer on USB for more than the bare minimal time to download files it really eats up the battery.  The couple of times I've been uploading or downloading and forgotten it's been plugged in for maybe 10 or 20 minutes, it seem to use up the battery alarmingly.  Today despite  only having done a total of 6 hours riding since recharge the Sonyo Enloops were flat at the end of todays outing.  But I'd used the eTrex on the computer for maybe 20 minutes.  The Enloops should do 20 hours+ when fresh

I'm surprised, I don't have one but I would have assumed that it would power off the usb when it's connected like the others [Vista/Legend at least].

Mine doesn't appear to have this problem.
