Runs for days! Quite so but in trickle mode or hibernation mode. But in use and what it is meant to be used for 11 hours is about right.
The power settings on my Active 10 are;
Power Saving - Off after 30 minutes.
Screen off - 1 minute
Alert when screen off - off
I do tend to power it up at the start of a walk, and then prompt it every half hour or so as I like it to log the route details etc.
I think the key is not to have the screen needlessly powered up.
TGO have a review on their web site -
http://www.tgomagazine.co.uk/review/review-satmap-active-20-gps/ I really like the idea of having 1:50,000 1:25,000 and 1:10,000 maps loaded on the unit.
The review reckons 10hrs for the battery but doesn’t state what power settings if any they used. So that figure tells me nothing really. The default settings on the Active Ten will keep the screen powered up whenever the unit is on, which is gonna just drain the battery pretty quick.
I note the touch screen, but thankfully that can be turned off – but it’s still another pointless feature to pay for.
I am surprised at the USB port cover. Would have thought after it having been a flawed design on the 10 they would have gone for a belt and braces option on the 20. That’s really disappointing.
I don’t know anything about Garmin units.
