First post here so please be nice. Since taking delivery of my Model 3, I've set the battery charging limit to 90% and was consistently getting 279-281 miles when charged "full". Just last week, I've noticed that 90% only charges me up to 274 miles. I've had my Model 3 for a month and have 1,900 miles on the odometer. I've only been charging with Level 2 chargers and 2 instances of 15 minute supercharging. Should this be cause for concern?
