———————————————————————————
When driving my car used less charge than estimated, so my real SoC was different from estimate in ABRP, so ABRP's plan did not make sense. I can't use the phone to edit the plan while driving, so I'd like CarPlay to have buttons like +5%/-5% charge adjustment to sync state with the car.

I don't have any hardware dongle and my car can't report charge to the phone automatically.
