I’ve been suspecting that the capacity is slowly going away, in small increments as what you mention in your case. But I’m amazed at how well the battery has kept up considering what I’ve thrown at it. I’ve often charged twice a day.
I agree. The Absolute battery capacity between 75 and 100% drives me nuts.
You’ve managed a lot of mileage for few cycles. I only get 35-40 kilometers on a charge due to hills, lights on all the time, and 45km/h drive. So I haven’t been as efficient as you in keeping down the number of cycles.
