Hi, why are you only charging to 80%? Honda on P.563 of manual states; "To help extend the lifespan of the battery, it is recommended that you fully charge the battery each time prior to driving."
I do hope you have switched off the phone charging pad, high energy user, in use or not.
I charge to 100% as instructed, Honda apparently can tell how you charge, when you charge and where.
I certainly obtain 180-195 (Last week in snow) that's with cabin heat on around 22 degrees, occasional seated heats and steering wheel heat.
