While they were happy with what the fairphone 4 brought to the table, they seem to like what was changed for the fairphone 5.
What are you guys' opinions on this? A welcome change? would you get one if your phone died within the next year?

Begs the question why aren't charging jacks designed like audio jacks?

[–] turmacar@lemmy.world 8 points 11 months ago* (last edited 11 months ago) (2 children)

If you wanted them just for charging it would be fine. Barrel jacks are still pretty ubiquitous.

If you want them to also be data they get less great. They make 3.5mm/etc jacks with 3 "pins" and I assume more. But every time you're inserting/removing the cable it's rubbing past the insulators separating the contacts. Their failure per plug/unplug is higher than something like USB-C where the 24 contacts are being pushed together instead of brushing past each other. It would suck if you put in your USB-barrel and one of the contacts broke/bent.

It's actually a bit crazy - and very impressive - that the cable I use to tickle-charge my phone at 15W could also be used to connect four 4K screens, an external GPU, multiple 10GBe network adapters all while providing well over 200W of power... if my phone supported and of that, that is.

That's just the USB-C standard, to get 200W and 4k video you need the fancy shielded high-gauge cables.

[–] Petter1@lemm.ee 1 points 10 months ago

Well for only 4k, a relatively normal USB-C cable is enough, the fancy cables are for 20 and 40 Gbit/s which is only needed if you gl crazy with your FPS | Hz (more than 60Hz | FPS

Typical stereo headphones have 3 pins. Left, right, common ground. Tip, ring, and sleeve (not sure if the conductor order).

4-conductors used to be common for portable camcorders and early digital cameras. They’d put our composite a/v (extra conductor for video/yellow, still a shared ground). Tip, R1, R2, sleeve.

I’ve seen USB 2.0 (or perhaps 1.x) done over a 4-pin 3.5. And I’ve seen RS232 over 3.5 a number of times too (used to be common in ham radio in the 90s/early naughts).

The video ones are what I was thinking of. Fair enough that I forgot to count ground.

[–] stealth_cookies@lemmy.ca 5 points 11 months ago

There are plenty of products out there that use TS style audio plugs (more 2.5mm in my experience than 3.5mm) for DC power for portable devices. When you get to data transfer requirements, the higher pin counts of current connectors wouldn't be space efficient.
