What sort of mileage have you done to have a have a SOH of 69% - that seems low for a car still in warranty?
Just recently ticked over 55k miles, and yes, I agree it seems low for a car with more than a year left on the warranty. The good news is the car has enough range for my needs right now (especially with coronavirus), and I'm hoping by the time it doesn't that BMW will have a way to increase my range and/or a battery upgrade is practical.
I am inclined to believe the Electrified app is "correct" (or at least close) on SOH. My Batt Kapa Max readings are hovering around 13.2 right now which works out to 70.2% of the 18.8 kWh usable capacity I have on my 2014. It's a bit interesting that Electrified and the Batt Kapa Max don't come out to the same percentage. I would have assumed the SOH and Batt Kapa Max readings would be coming from the same place in the car.
I had my car in BMW for the brake fluid change within the past year and asked them to test the HV battery. They said it 'passed' without giving much additional information. They did not
do the comprehensive battery run down test that some folks have reported and I assumed that they used some BMW proprietary tools/ procedures but now it looks like everything they showed me is available in the Electrified app.
