Your and my experiences are anecdotal. I follow the assorted FB groups for the Edge series, the 1030 and the Hammerhead Karoo. One thing that is never consistent is battery life, which is often all over the map. Somebody on the HH site reported near 19 hrs, of battery life. I've never seen more than 12 to 14 and right now and for unknown reasons is down to 8 or 10. The Edge site has people constantly complaing about the 520 with 4-6 hrs. Others have no issues. No explanations.
