      That has nothing to do with whether it’s USB 2.0 or 3.0 because it’s backwards compatible. What phone do you have?

        How is it backwards compatible with fast charging if it only fast charges in 3.0 ports but not 2.0 ports? It will work in 2.0 sure, but it doesn’t fast charge over it since 2.0 doesn’t have the same electrical output as 3. I have a LG Thinq V6.

            I paid $350 for it, for certain. I thought I got it in 2018 but it seems I’m just misremembering.

            The main point is that android certainly uses USB 3.0 pretty commonly, and not just 2.0. If it fast charges, it ain’t fucking 2.0.

              Bro, you don’t really know anything about USB

              The port being USB-C has nothing to do with USB 3.0

              The port supporting fast charging has nothing to do with it being USB 3.0

              Unless you have transferred data over the wire and seen USB 3 speeds, you can’t claim it to be USB 3 based on circumstances alone.

              On the other hand, I can totally imagine that 99% people never transfer any data over the wire anymore. Airdrop is fast and convenient if you have a Mac and other solutions exist if you don’t. You can easily get 10 MBps+ transfer rates over Wi-Fi and that works fine for most people, if they ever need to transfer data over to a PC anyway. So I’m guessing Apple just took what majority would accept and went with it, just like any other company does these days.

                Really now?

                USB 2.0 has the same power output as USB 1.0 and does not support fast charging.

                From wikipedia. If the port on the device only supports 2.0, how does it handle the extra power input to allow fast charging? And what devices have a USB-C port that isn’t using the 3.2 standard?

                  It’s a little complicated. A USB-3 connection must provide higher current 900mA than a USB-2 connection 500mA. As such a USB-3 data connection can charge faster than a USB-2 connection - some people may call this “fast charging”.

                  However USB-PD (Power Delivery, aka fast charging) was released as part of the USB 3.1 specification, but it does not require a USB-3 data connection and neither does a USB-3 data connection require USB-PD. You can see all the different USB-C modes on Wikipedia as well, where USB-2 and Power Delivery are listed separately: https://en.wikipedia.org/wiki/USB-C#USB-C_receptacle_pin_usage_in_different_modes

                  That’s the part you are missing. Modern charging doesn’t use standard USB power. That’s the whole fast charging landscape is addressing.

                  Read this https://www.androidcentral.com/qualcomm-quick-charge

                  The power brick can supply more than 5 V over a standard USB port because it’s not adhering to USB standards for supplying power. As a result, data and power are decoupled, allowing the power brick to supply more than a standard USB port over a connector and cable which are identical to USB ports and cables.

      Disagree. My Redmi Note 11 can charge up to 33W using my current Anker Nano II (65W), previously UGREEN 20W charger. It has USB-C 2.0 port.
