Not that a new connector is around the corner, but I love how people try to act like this will be an achilles heel for these laws. How long will it take to vote in an amendment that updates the connector?
I get it, being anchored to one connection type sounds good now while it's still somewhat new, but in 10 years it could be a burden. Still, I do not want to go back to the days of every device having a unique barrel connector.
Many people have been taught regulation is bad, not much logic to it.
USB-C as a connector can easily last a decade, much longer for just power delivery.
Exactly! Most electronics are surprisingly low-powered, but USB-C can currently support 100W with a draft spec with upwards of 240W. We'll be fine for awhile.
Yeah, USB-C is fine for even mid-grade laptops. Realistically, if your device is using more than 100W then it probably has an IEC plug (or at least, an in-line power brick with an IEC port) instead. Pretty much the only thing USB-C isn’t suitable for currently is gaming laptops, because those easily draw upwards of 200W.
They arent suitable for gaming laptops while gaming. They are fine enough to just charge during light/no usage at somewhat reduced speeds.
The USB-C EPR spec allows for 230W charging.
The Framework 16 releasing later this year will be the first laptop to use the spec with a 180w power supply
USB-PD 3.1 standardized EPR in 2021; it hasn't been draft for a while.
I'd be surprised if USB-C was a limitation on phone technology even by 2040. The bandwidth and power delivery capacity are way beyond what are needed now. Data transfers from phones are going to increasingly move to wireless in that time frame too, I expect.
The limitation on the viability of USB-C with phones won't be the actual technological viability of the standard with respect to phones. Instead, the problem for USB-C for phones will be if another standard comes out and starts being used by other devices that do need higher bandwidth or power delivery capability. Monitors, storage devices, laptops (etc.) will eventually need more than USB-C can provide, even with future updates to its capacity. When those switch over to something new, that will be when phones (and other devices) will need to consider a new standard too.
Remember what we said and acted on 20 years ago about technology? Yeaaahh...That's what yousaid right now.
This is speculation based on the combination of physical constraints and changing usage.
Phone batteries today are in the 10-20 watt-hours range for capacity, or at least iphones are and that's the data I found. Going from the typical ~20W fast charging rate to the full 240W capacity of USB-C EPR would allow a twelve times increase in battery capacity with no change to charge times. Are batteries going to increase in capacity by twelve times in the next 17 years? I'd be shocked if they did. The change from the iphone 1 to the iphone 14 pro max is 5.18Wh to 16.68Wh — a three times increase in 16 years.
Likewise, with data transfer, it's a matter of how human-device interaction has shifted with time. People increasingly prefer (a) automated, and (b) cloud based data storage, and (c) if they do have to move data from device 1 to device 2, they would rather do it wirelessly than with a physical connection. USB4 on USB-C is meant for 80 Gbit/s = 9.6 GB/s transfers. That's already faster than high end SSD storage can sustain today, and USB4 is a four year old standard. People on phones are going to be far more likely to be worried about their wifi transfer speeds than their physical cable transfer speeds, especially in 2040.
Then, on top of all of that... USB will continue to be updated. USB-C's limitations in 2033 will not be USB-C's limitations in 2023, just as USB-C's limitations in 2023 are not the same as USB-C's limitations at its inception in 2014. In 2014 USB's best transfer rate was 10 Gbit/s, or 1/8 what it can do today.
Why do mobile devices and computer hardware need to utilize the exact same wire? I am fine with their being two, as long as it doesn't turn back into a half dozen types of cables again.
Usb 1.1 came out in like 1994, I still use it for keyboards and mice, ie the main thing I plug in to my pc. USB 2.0 came out around 1999, that covers most everything else.
Usb 3 is from 2009 or so, most of us don't bother with them except for storage because they're overspecced otherwise and usb 2 is cheaper.
Usb 4 will be fine in 2040 unless something weird happens, we'll still be using usb 2.0 because the cables are cheaper and more flexible than 3.0, we'll just call it "USBx4.2 base profile"
USB4 is actually faster than DisplayPort 2.1 and I don't think we'll go past 8k at 165Hz any time soon. When it comes to storage at some point you really want an SFP port currently maxing out at 400Gbit (as opposed to USB4 120Gbit, and that's asymmetric). For reference: You need to drive the NIC with PCIe 5x16 to saturate that. Unidirectionally. Network speeds are nuts you need specialised hardware to keep up with the cables.
Laptops why yes that's what USB is for.
I collect old handhelds. Each one having a unique charging and/or sync cable fuckin sucks and I'm so glad that USB is ubiquitous. My current daily driver has mini USB for data, but charges using a unique connector that plugs into a unique cradle that sends power to the device when hooked into the cradle. Without the cradle, ya ain't charging this thing.
Well USB-C was published 9 years ago, and has been well-established, nearly ubiquitous for at least 5. Why did this take so long?
EU version has review process built-in. Anyways it'll be hard to get more outdated than lightning.
Depends on what corporations and countries are backing it probably.
I thoroughly agree the connector insanity was a pain in the ass (though, being a hoarder of cables it made me a sort of superhero) but I just really dislike governments dictating this kind of thing.
USB-C is a connector shape, so there's really no need for a USB-D. What you're thinking of is USB 5.0, except the USB has a penchant for coming up with the dumbest names imaginable. The current latest (I think) version is 3.2 Gen 2x2, so the next major version will probably be called some bullshit like USB 3.2 Gen 2x2+1.
How immature.
Regardless, I have to say:
Gottem.
USB One
USB4 is here and is already being called weird stuff.
Thankfully it's not the 90s or they've called this "USB 3.2 Gen 2x2 Extreme"
Wikipedia lists USB4 Gen 4 (No space between USB and 4, which is different from previous versions which did have a space there).
Following USB4 Gen 2×1, USB4 Gen 2×2, USB4 Gen 3×1 and USB4 Gen 3×2.
If the USB-IF can agree on it, why not?
The USB-IF moves so slowly it might as well be standing still.
I think it's good for USB standards to move slow.
Finally just about every device I buy has USB-C now. If they release a new connector that'll just mean using 2 different cables for everything again.
