I can’t believe some of the points Linus made against the Fairphone, especially given he’s onboard with the same compromises for the Framework laptop. 🤭

    Phones don’t use much energy. I’m not getting the “efficiency” thing for wireless charging. Even new standards are basically the same.

    This CEO sounds like he has no idea what he’s talking about

      The long and short of the lower efficiency of wireless charging is a concept called Free Space Loss

      In order for energy to pass through an open space it has to use some energy. Unlike a cable where the pins are contacting and the loss is far lower.

        Yes but it’s not massive amounts.

        Phones use practically no energy compared to PC’s laptops, washing machines etc.

        And if people want that level of charging efficiency… The USB C port still exists…

      Energy lost as heat during the power transmission. It’s what makes the phones warm during wireless charging. That heat decreases the lifespan of the battery and makes the phone uncomfortable to use, which is why wireless charging speed is limited once the phone reaches a certain temperature. I specifically avoid using wireless charging on my Pixel to extend its battery lifespan since it will live for 7 years and battery replacement is expensive. New wireless charging standards could probably play with frequency and other parameters in order to reduce energy lost as heat, similar to how increasing the voltage in a circuit decreases loss to heat for the same cables.

        Yes but that’s mostly relevant when using fast wireless charging. Slow wireless charging doesn’t get that hot. And it reduces friction on the USB port.

        Furthermore this phone has a swappable battery so it would be fixable if the battery degraded

        I can think of reasons to not to include wireless charging such as repairability. The efficiency is bs as people can still charge wired if they want to.
