I see a lot of people complaining that the Fairphone 6 doesn’t have an Aux jack.
Just use an adapter cable.
A 3.5mm Aux jack takes up a significant amount of space just to connect a few wires that could be connected through USB-C anyway, that space could be used for a bigger battery.
Even if there was a good enough reason to keep Aux it should be 2.5mm Aux and not the usual 3.5 as it does exactly the same thing but uses less space
In Samsungs (I repared a lot of those) for instance the Audiojack had always been a small component that clicked into the casing and connected to the sub board or on the S10 onto the mainboard (doesn’t have a sub). Also, it didn’t take much more space compared to the USB connector. The battery wouldn’t get to be any bigger because of the lack of an audiojack. You also need other stuff there like speakers, which take up way more space.
