I see similar behaviour, while the first one seems more severe, I wasn’t able to come up with a reproducable missbehaviour - just sporadic, which is hard to pinpoint.
But for the second I’d assume that it’s actually bad for LiPos to be kept fully charged permanently, so you might have to do a long term test if it will cycle the battery - where three days should have been plenty time to test.
As in the other thread mentioned three weekend/bank holiday days are not representative for the Particle response time 
It’s a business with business hours after all.
