Title. I mean it just makes no sense, my S23 takes about and hour and 15 minutes to charge with my power brick from 15% to 85% but it only takes 40 minutes with my car charger. What’s going on here?

I use the Samsung 35w power adapter, with a usb-c and a usb-a port, and my car charger is a Nulaxy NX12 bluetooth fm transmitter.

    The Samsung 35W charger has 2 ports, a USB A port that does 15W, and a USB C with PD upto 35W. If you have your phone plugged into USB A, it will be considerably slower than your 18W car charger, on the other hand, if you get a USB C to USB C cable, youll be looking at 25W charging (the animation changes on the S23 from Green to Blue). But 25W capabilities are also dependent on if youre using only 1 port of the 35W charger or both. If youre using both, it will probably default down to a slower speed too.

    The Samsung charger starts charging faster, so you’ll get more charge in less time. It then slows down to manage heat and does the last part of the charging slowly. This is meant to get you to a usable charge as fast as possible.

    The other charger doesn’t generate as much heat early on, but also not as much charge, so the phone chooses to charge faster later in the process.

      But the thing is it doesn’t though. I leave my phone plugged in the car charger during the ride home from work, which takes like 10 minutes, and it charges WAY more than if I leave 10 minutes in the samsung charger.
