I purchased this unit coming from my 1030 on the premise that it would give me far more usage time between charges , on watching a number of YouTubers advocating the 1040’s ability to go way beyond 24hrs continuous use …on swiping down from the top panel and pressing on the battery icon I only ever see a maximum of 19hrs of usage time and that is with map hidden , backlight reduced , gps turned to minimum etc ….have I been duped ?
