    It used to charge 6.4 kWh and drives 29 miles, now after 5 years and 52k miles it charges 5.5 kWh and 25 miles. Among 52k miles a little more than half are with EV mode.

    If the hybrid system still reserves the same amount capacity, I can assume battery capacity reduced from 8.8 kWh to 7.8 kWh, that is 11% lose.

    I’m not very sophisticated with measuring my battery’s parameters but my vehicle with similar use levels to yours last week gave me 31 miles. It was warm, but not warm enough to turn on the AC. This seemed similar to what it was when I purchased the car over 4 years ago.
