Same here. The email I got back from Leupold was to: Take the battery out for at least 4 hours, then replace with a new battery...Didn't work. It also shuts off after 5 min. Then when I turn it back on, say at a match, the brightness changes. So now I turn it off after my run, then turn it back on to start. It mitigates me standing there after "make ready" and cycling through the brightness to get back to my setting. I just bought another one for my other gun. Hopefully this isn't systemic. I'll be sending the faulty one in after the season.
