Ring 3 Pro Eating Battery power

I have a recently purchased Ring 3 Pro doorbell.It is literally eating battery power at 10% per day. I have turned off all features like motion detection - the only feature remaining is the doorbell. I purchased a Chime pro and switch to the chime pro network - no difference. I have also purchased the solar charger fitting - again little difference. I have a mesh network to boost wifi, so I connected to that - RSSI at about -60 - again little difference.A doorbell which can not even last a week on its batteries is ludicrous - what happens when we go away?Can anyone advise if this is a known problem? I do not have a particularly large house, and I have tried everything I can to diagnose the problem.Looking for helpRon Holmes
