The SOC meter has read 77.5% (218 raw) after my last two 80% charges. I am pretty sure a week or so ago, it read 80% and 80.4%.
It has been fairly hot here but the battery temperature still shows 6 segments. My hypothesis, based on my extensive Arts and Humanities background, is that the battery capacity has gone up with the heat and that the raw numbers are not constant. We can correlate this when we have access to finer battery temperature data. Meanwhile, I will be tracking the readings after charging.
