TL;DW: Fast charging over 2 years only degraded the battery an extra 0.5%, even on extremely fast charging Android phones using 120W.

And with that, hopefully we can put this argument to rest.

    Non-magnetically-aligned wireless chargers are far worse than fast charging.

        At killing batteries faster - the wasted energy creates heat, which degrades the battery.

          But keep in mind the phone will throttle charging speeds when it gets warm, so the battery doesn’t end up getting much warmer, it just takes forever to get a full charge (especially when using a thick case that puts further space between the charging coils and also acts as thermal insulation, thus reduces the phones ability to cool down)

          They tested that too, actually. Heat, I mean. It’s in a different one of the channels videos. It’s easy to find, since the channel only has like 10 videos and only a few are about phones .

          It’s literally a few watt hours. Not kilowatt hours, watt hours. I pay $0.08 per kwh, so after a few years of wireless charging I might pay $1 more

          But the USB-C cord might break in less than that time and cost more. Manufacturing cords is never going to be green, but electricity can be made renewable

            The charging pad might also break and they require cables themselves, plus all the materials to make the charging pad, plus every phone has to support wireless, which is even more materials. I’ve never broken a USB-C cable, that’s a user issue, you are either being way too aggressive with them, buying low quality ones, or both.

              You keep on connecting and reconnecting the USB-C cable, and if you use it while charging you probably bend it.

              The cable in the charging pad never gets unplugged

                You can’t use a wireless charger while in bed. Unless it’s magnetic, then it’s also got the bending risk.

                I lay in bed all the time with my phone charging, the cable bends, but I’m aware of it, it’s never broken. I’ve had this specific one for 4 years now.

                What if I want to charge in a different room? Do I buy another wireless charger? That’s more cost and material again versus just a cable. Do I unplug the charger and take it with me? Cables just make way more sense. Your phone is tethered to something either way, might as well do it the more efficient and green way and plug a cable in.

                  If you yank a magnetic stick on charger it just disconnects. If you yank a wired cord it can break it.

                  I never said you must stop using wired charging. If you’re using it while charging and it works for you, you can continue to do that.

      Wireless charging is a gimmick like 3D TV was. There’s only one use case, and it’s car use. But it doesn’t need to be fast. In every other case it’s worse than cable in every aspect

          You’re so cool. You can just throw your phone at charging plate to cook itself, while you can’t use it. But it looks cool. Cool tech for cool people.

            It makes my wife considerably less pissed off when I come to bed late and am not fumbling with cables, so it’s a win for me.

        A phone with wireless charging is a bit niche, but if only all my little devices had wireless charging; earbuds, vape, tablet, controller, remote, etc. I’d set a charging mat in the middle of the coffee table and have all my devices just be charged and ready to go. Now it’s just a mess of wires, with the only thing I keep glued to my hand featuring wireless charging!?

        Wireless charging sucks. It costs significantly more energy to charge the same battery to full.

          Your phone doesn’t have that much energy stored in it. 5 watt hours or so? Now consider the energy cost of making usb-c cords

            The charging pad itself probably requires a USB-C cable itself? It takes much more materials to make them than a cable…

              It doesn’t have plugging and unplugging cycles and doesn’t get bent in different directions, so it will basically never break unless you use the phone while holding the charging pad

                So I’m expected to hold a wireless charger as well? When I can just have a light cable plugged in, generating less heat and for less time? Unless you are buying really low quality cables, they shouldn’t break and unless you are aggressive with it, the cable and the port will last years. When they eventually wear out, the cable is recyclable and depending on your phone, the USB-C port replaceable.

                Wireless charging is for toothbrushes.

                  Nobody said you must get rid of wired charging.

                  Over four years I’ve broken three or four cables. Every time it’s because the phone moved while plugged in. Whether it’s my error (forgetting it’s plugged in) or the cat knocking the phone down, nothing breaks when the phone falls down from the wireless charger

        yup, the chinese brand have it right. Fast charging is amazing, just put the phone on charge for like 10-20 minutes and you can forget about your battery for another day. It’s great.

          I have a one plus phone.

          The super vook charging works very well. It feels like less than 10 minutes to go from 10 to 80 percent.
