Slowcharge / scheduled charging problems + android auto shenanigans

Slowcharge / scheduled charging doesn't work as intended, I have set up the sheduled charging to 00:00 to 6:30 and turned on slowcharging to save my battery, yet instead my phone just charged from 5% to 100% in an hour or so, am I just using this thing wrong or what?

Also Android auto seems to mess with my darkmode settings alot.. I plug my phone to my car with dark mode on, as usual it goes to light mode if the car hasn't been set to dim mode, but when I unplug the phone, darkmode flips on, and almost instantly back to light mode, while disabling dynamic screen brightness every time... love the phone but these things are driving me nuts
