At that scale, the connector and the necessary electronics are too large.

Some watches already have USB - C. but I find it interesting to see if you are correct or not.

I would see standardizing wireless charging as a decent alternative...if it didnt take up even more space.

roofuskit@lemmy.world on 05 Aug 21:05 next collapse

It’s also hard to make a port like that water resistant. Using wireless charging is easier to make flat and seal tightly.

Zak@lemmy.world on 05 Aug 21:14 next collapse

If you mean a USB-C port in general, they can be made waterproof. If you mean something specific to putting one in the most compact form factor possible, that might be true.

roofuskit@lemmy.world on 05 Aug 22:25 next collapse

And that requires more space than a typical port. In a compact device that is difficult. A flashlight is literally one of the simplest electronic devices there is and bulk is often a plus for comfort.

You might be surprised at everything going on inside a modern flashlight. I’ll grant that it’s probably easier to find room for extra seals around the port than in a smartwatch though.

roofuskit@lemmy.world on 05 Aug 23:25 next collapse

Still not nearly as complex or compact as a smart watch. A little microcontroller versus an arm processor.

A switch mode LED driver can be made very tiny with as few as 4 components. Battery protection and a single cell battery charger can also be very simple.

They can be waterproof but are also non functional until the water is fully cleared from the port.

That kind of waterproofing wears over time (years). It keeps it’s resistance, but not a submersible seal. Watches have longer use years than phones on average.

It's not that it's too large to exist, but it's certainly large enough that it'll make a dent in the battery space, and smartwatches are already battery-starved compared to dumb ones.

Its a terrible idea for a number of reasons, but as everybody else is saying, that doesn't mean you give up on standardization.

edent@lemmy.world on 05 Aug 21:35 collapse

I wrote the post above. So far, the USB-C watch has lasted over 3 days and still has over 50% battery power.

Obviously, at that price it isn’t running a cellular radio or GPS. BLE is amazingly efficient - as are the built in sensors.

mesamunefire@piefed.social on 05 Aug 22:23 next collapse

3 Days is great!

MudMan@fedia.io on 06 Aug 05:07 collapse

That gives me no information. What's the battery size? I've had multiple smartwatches and all their batteries could last a week or a day depending on usage, setup and features.

The point is USB C is noticeably larger than pogo pins for the sake of including a whole bunch of additional pins a smartwatch has zero use for. Larger means less room for other stuff. The ideal state for a smartwatch is having an always-on display and heart rate monitoring, among other things. All watches out there, even the most efficient ones, could use more battery and efficiency than they have. Because all smartwatches are coming up short from their desired usage and are working around their limited battery life.

The idea of making that worse for the sake of having a clearly unfit for purpose connector as opposed to standardizing a connector that actually does the job is really weird. There is no need to have a different charger on every watch, but there certainly isn't a need to sacrifice any functionality or performance at all for the sake of USB C. And not all watches are the same size, so this would impact smaller watches more, which now is limiting what type of watches you can make if you make USB C a standard. And if it's not a standard, then it's not fixing the problem.

And all that's even before you begin to consider that watches are more comfortable to charge when they have a stand to do so, since they're small, light and fiddly, so it's entirely possible for a bulky USB C cable meant for fast charging to be heavier than them or stiff enough to actively move them around. There's a reason watch chargers tend to come with very thin, flexible wires. All you need to fix this problem is a magnetic stand that can hold any watch. Half the USB C cables I own would knock over my watch stand if plugged into my watch or drag my watch across the table.

You can make a watch that charges via USB C and still works. That's not an optimal solution, but you can. But it's not a valid standard because you can't very practically make all watches charge via USB C. Standards need to be standard.

edent@lemmy.world on 06 Aug 08:29 collapse

What’s the battery size?

The website claims 280mAh. That’s a smaller than the newest Pixel watches - but then it is only about 10% of the cost of those models.

The point is USB C is noticeably larger than pogo pins for the sake of including a whole bunch of additional pins a smartwatch has zero use for.

Agreed! But that rather depends on what you want to use it for. This model is charge only. But it could be useful to use it as a USB drive to store music, or to get health data off it. The main advantage for my personal use-case is being able to charge while wearing it.

The ideal state for a smartwatch is having an always-on display and heart rate monitoring, among other things.

Yes! This does have always-on heart rate monitoring and step count. The screen is only on when you glance at it or tap the button.

And if it’s not a standard, then it’s not fixing the problem.

Agreed! But as the Pixel watch has gone through three different charging standards, all of which are incompatible with other watches, we don’t seem to be any closer to solving that problem with wireless.

And all that’s even before you begin to consider that watches are more comfortable to charge when they have a stand to do so, since they’re small, light and fiddly

That’s a personal preference. My Pixel watch stand is fiddly to use - the magnets don’t always align. And the puck charger is pretty lightweight and moves around easily. By contrast, my lightweight USB-C cables don’t move my watch when it is charging directly.

Standards need to be standard.

I agree! But sometimes it is nice to experiment with things to see what works. And I’m very happy that this normal-sized watch is able to charge with the same cable I use for my toothbrush, eBook, headphones, fan, and phone.

MudMan@fedia.io on 06 Aug 09:58 collapse

Hold on, so now you want to use USB C for data transfer? Which means you want to what? add more storage to the watch? That sure seems like a solution looking for a problem you're only floating as a result of choosing USB as the charge port, which we probably shouldn't do.

And that's not just much less battery than on the Pixel at 420mAh, it's even smaller than the CMF Watch 2, which reports 305mAh and is only seventy bucks (and if anything seems smaller than all of your examples). So yes, there is an impact on battery. And no, that's not acceptable. Because again, ALL smartwatches need more battery than they currently have.

The point of the always on HR monitoring and screen isn't that they exist, it's that they are a massive battery drain. A smartwatch where you turn those off will last several times more than the same watch with them on, particularly on entry-level devices like ones you point at. And you would ideally wnat those on in a perfect smartwatch while still getting multi-day battery life. Right now we just don't have that because you can't work your way around physics.

Now, for an experiment? Sure, go nuts. Put a solar panel in there. A hand crank. Who cares, weird hardware is weird and weird is fun.

But to solve the problem with the ever-changing charger standards from the mainstream manufacturers weird won't cut it. You need a solution that fits all cases with near-optimal performance. USB is just not it for this form factor, and if anything focusing on it distracts from the very real need to come to a proper standard in this space, which I find somewhat annoying.

edent@lemmy.world on 06 Aug 16:43 collapse

Hold on, so now you want to use USB C for data transfer?

Sure, why not? My headphones have a built-in MP3 player which I can load up with 32GB of music. Flash memory is tiny and cheap - why shouldn’t my watch have my music collection on it? Is grabbing a CSV of my data via USB easier than trying to send it via BT? Might be. Let’s find out.

Because again, ALL smartwatches need more battery than they currently have.

For you, maybe. This £16 one has lasted nearly 5 days of doing continual heart monitoring and is still on 40% battery. Even better, I don’t need to take it off if I want to charge it. Weekly charging is better than my phone or laptop.

I slightly disagree with you about the screen needing to be always on. I’m not always looking at my watch, so it might as well save battery where it can. I don’t leave my laptop screen on when I walk away from it, and that has a much bigger battery.

weird hardware is weird and weird is fun.

On that we can agree! This is a fun experiment.

You need a solution that fits all cases with near-optimal performance.

I disagree. I think it is OK to have some choice in the market. Some people will prefer magnetic wireless, some wired, some plutonium batteries.

and if anything focusing on it distracts from the very real need to come to a proper standard in this space, which I find somewhat annoying.

Like, mate, I don’t have the power to enact anything. I’m just one guy blogging. I’m not involved in the design, manufacture, or standardisation of anything watch related. I don’t understand why you’re getting annoyed by me talking about it though.

MudMan@fedia.io on 06 Aug 17:39 collapse

Flash memory is tiny, but it's not replacing anything, it's being added, which is a problem for cost and size. If you were going to take BT out then... sure, but that's not what's happening here.

Now, the conversation is different if you reframe it as "I just like this quirky dirt cheap watch with a USB port on it". At that point I have nothing to say other than... sure, why not.

What I don't like is the notion that USB C is either a better alternative or a candidate for standardization, which is how the post came across to me.

Oh, and I disagree about the always on screen, too. In all honestly, the two things that make smartwatches still less polished than traditional watches is a) battery life, and b) the fact that there is at best a second of lag when you try to check the time and at worst you need to shake your wrist to try to get your watch to realize it's being looked at so it decides to wake up.

There's no question that having a display of the time on at all times is better. It's just not practical with the energy costs and battery storage. At one point I bought that Garmin watch that has a standard old digital watch screen on top of the modern display (speaking of weird). It was a neat idea, but it turns out that the battery life for it on normal use wasn't much better than other watches and the dumb thing still had a backlight it turned on via motion detection, so it was just as laggy as a normal smartwatch.

I'd take a better iteration on that tech over a USB C charger any day, if we're doing weird.

edent@lemmy.world on 06 Aug 18:51 collapse

In which case, you might like the eInk screen on the Watchy. I reviewed it at shkspr.mobi/…/review-watchy-an-eink-watch-full-of…

Screen is always on but eInk gives it great battery life. Although the rest of the watch is even more experimental than the USB-C one 😆

MudMan@fedia.io on 06 Aug 19:44 collapse

Hah. That's the kind of weird I can get behind, but I definitely wouldn't want it to be the default.

Also I'm not sure how I feel about the possibility of the watch dying and it getting stuck on giving you the wrong time. I guess it's how old analogue watches worked, but there's something to knowing when your watch is dead.

BussyCat@lemmy.world on 06 Aug 04:07 next collapse

Some do, but the limitations of usb C (or any physical plug) are present and while it sounds nice in principle to have all the devices use the same cord it’s in general not worth the sacrifices that others have mentioned like it taking up extra room and the increased likelihood of water/sweat/particulate ingress

medgremlin@midwest.social on 06 Aug 10:20 collapse

I have the pixel watch 2, and waterproofing is very important to me when it comes to a smartwatch. I work in healthcare and have to wash my hands upwards of 30 times a day. If I had to take off my watch every time or gamble on a rubber flap adequately covering the charging port, it simply would not be worth the hassle.

edent@lemmy.world on 05 Aug 21:32 next collapse

And yet, I literally have one on my wrist now. It’s not noticeably bigger than the Pixel 3 watch.

natecox@programming.dev on 05 Aug 21:40 next collapse

This is confirmation bias, you know it’s possible so you’re discounting downsides.

Yes, a connector can fit in the watch, but the internal footprint of the connector is comparatively huge. All the other components of the watch would need to be designed to fit around a large connector essentially directly in the middle of the device internals.

If that’s really important to you, more power to you. I don’t have an issue with it existing. I do have a bit of a problem with pretending that compromises aren’t being made in features to accommodate it.

A standardized magnetic pogo pin connector would meet my needs quite a bit better, personally.

The charging base is just breaking out the 5V of the USB to the pogo pins!

I’m not discounting the negatives - I’m saying it is possible and feasible.

As I point out in the article, the Pixel watch is now on its third charging format. None of which seem to be compatible with Apple or Samsung.

There are also compromises with the pogo-pin connector. You can’t charge while wearing it. You have to bring along another cable. Bits of metal can be attracted to the magnets and cause mechanical or electrical damage.

Not really relevant: power requirements would affect battery size much more than charging port size. And USB-C supports much greater power transport than the old dock connector.

dual_sport_dork@lemmy.world on 06 Aug 15:32 collapse

Given that an iPod nano only lasted a few hours on a charge and most smartwatches can last multiple days, I’m pretty sure that’s not so. Even if they had apples-to-apples identical functionality I think a modern device would consume less power simply due to current chips being more power efficient via using smaller dies and lithography processes.

Plus, an iPod has to crank its weedy little processor full time as long as it’s playing music. Your smartwatch pretty much only has to do anything when an external stimulus wakes it up, be that pressing a button or tapping its screen or receiving an alert or whatever. I’ve developed software for some of the Garmin models myself and I can tell you that the power consumption and processing time limitations imposed by the system are extremely stringent. The majority of the time even in a second-by-second basis your watch is completely idle, specifically to consume as little power as possible and conserve the battery.

SpaceNoodle@lemmy.world on 06 Aug 16:15 collapse

The last gen iPod nano touted a 30-hour battery life. Also, you don’t need to peg the CPU for rendering audio - this can be accomplished with a very low-power DSP. The lack of radios also offers significant savings when compared to a smart watch, which you forgot needs to be able to receive notifications, not just wait for low-power sensor input.

I’ve professionally developed the firmware for several embedded systems and consumer electronics devices with very strict power requirements.

dual_sport_dork@lemmy.world on 06 Aug 23:26 collapse

The 7th gen iPod Nano which you’re referring to (not the 6th gen the commenter above posted, which had a rated 24 hour battery life) had a 200 mAh battery.

A lowly Garmin Forerunner 230 like the one strapped to my wrist right now has a 150 mAh battery and achieves five weeks of battery life with notifications enabled (which I did not “forget”) and the BLE radio twittering away all day, GPS time and position updates, activity tracking, and the screen displaying content all the time. Not 30 hours. 840 hours.

Just acting as a plain watch with the connectivity turned off Garmin claim it’ll last 12 weeks (2016 hours).

I should not have to point out to anyone that it is physically impossible for an iPod to achieve a significantly shorter runtime on a larger battery without consuming more power in the process.

SpaceNoodle@lemmy.world on 07 Aug 00:57 collapse

Now imagine at best halving the physical space for that hall battery by adding a waterproof USB-C port and associated PD electronics - which at that scale would mean significantly more than a 50% reduction in battery life.

aion@lemmy.world on 05 Aug 20:53 next collapse

I assume you mean having a USB-C port on the side of the watch. Having that port would allow water to get in to the case, the cradle-style charges used by smart watches allow the case to be sealed to prevent water damage. Even if you are careful about not wearing the watch when bathing, or in the rain, or in a pool, its unlikely you remove you watch every time you wash your hands or wash dishes.

I think the better question is, why can’t wireless charging be more universal. We had decades of 500 different competing phone chargers. (as the famous XKCD comic xkcd.com/927/ ) mocks.

yet we don’t seem to be getting anywhere near the idea of a universal wireless charge system.

MudMan@fedia.io on 05 Aug 21:11 collapse

I mean, we are for phones. Qi2 is finally becoming more widespread, and the Qi1/Magsafe spec is quietly more compatible than its official support suggests.

Why this doesn't extend to watches and only partially to earbuds is a different question, but I at least the most likely devices to have wireless charging are getting there.

You kind of are, it's basically the same magnets+wireless combo Apple uses for their phones.

I don't know if you could use the same charger for a phone. Probably not. But it's a cross-company standard, so the idea would be to do the same for watches, if the standard doesn't include a watch option already (I haven't looked into it, frankly).

mesamunefire@piefed.social on 05 Aug 21:19 collapse

It would be a dream! And I imagine easier to repair as USB anything involves pushing and pulling a physical connector that will eventually break. It may take a long time, but anything that moves will eventually break.

Nice that watches ranging from £16 to £200 already support USB-C. My two Garmin watches both have (incompatible) unique charging/data ports.

acosmichippo@lemmy.world on 05 Aug 20:55 next collapse

The Verge says:

These devices are too dang small, and the technology isn’t there yet. Most standard connectors, like USB-C, are too large to fit within a smartwatch or on devices that are meant to mold to your body. The smaller the device, the more difficult this becomes.

To which I say:

Bullshit!

Watches are small, but the USB-C connector isn’t massive.

The USBC plug may not be “massive” but it still adds more bulk to the watch.

it might be rubbish as both a watch, Android device, and masc-coded jewellery - but it shows that USB-C is viable for devices of this class.

just because cheap ass watches use USBC ports doesn’t mean it’s a good idea. you need to know how these USBC watches actually hold up in the long run before you make that judgement.

I don’t know about the lesser Garmin models but I have a Fenix 6 Pro Solar and there isn’t enough panel surface area on it to indefinitely power the watch. Garmin only state that it “extends” the battery life by a few days. I haven’t tested it to see if you power the thing off completely if it will refill the battery from dead by any meaningful amount but I suspect not.

Not all of them have the solar option. In fact, very few of their lineup do.

Also: Garmin recently enshittified by simultaneously adding an AI slop component that works by taking all of your recorded fitness and location data and doing gods know what with it, as well as a paid subscription tier to their obligatory smartphone app – the latter after explicitly promising for many years that they wouldn’t.

Honestly, I’ve just been using my Fenix unconnected and it’s really surprising all it can still do. The only function I don’t have that I cared about was receiving notifications. The sensors and topo map and all still work fine and you can even still track rides and hikes, but you have to offload thr GPX tracks via USB and figure out what to so with them yourself.

As a current Garmin user I really like a lot of the features of the Garmin but the app for smart watch health tracking is atrocious and some of the values you get are clearly wrong like it recording my resting heart rate at 15 bps lower than it actually is.

The battery life is still insane which makes things like sleep tracking really nice

OhVenus_Baby@lemmy.ml on 06 Aug 12:43 collapse

I and my family have had Garmin’s like the venu line for years and I am in the hospital all the time. I’ve tested mine against the polar h10 and multiple medical tests and during times of Hospital stays for lengths of time. Mine has always been accurate and within a beat or two in the heart rate and a single percentage or 2 on pulse ox.

Garmin has fantastic customer service. Perhaps updating your device, or contacting them for an exchange would be worth while. All their watches I have had, seen, have been accurate. I’m not refuting what your saying just trying to give my perspective.

You can also set to track every second vs the default smart tracking every few minutes. Switch wrists as everyones vein layouts are better or worse to get a reading, keep it snug but not tight and not loose the sensor shouldnt indent your skin. Hope any of this helps. Don’t settle for subpar results or experience. They make good equipment IME.

BussyCat@lemmy.world on 06 Aug 12:50 collapse

I didn’t try actually contacting customer service about it but from talking to other people it has to do with how the watch moves around during exercise that gives the false readings. If I just sit still and compare to a pulse oximeter it stays pretty close but if I am biking or walking around the values change drastically. Then for some reason while when I sit down or lay in bed my heart rate is around 65 it says my resting heart rate is in the 50s

OhVenus_Baby@lemmy.ml on 06 Aug 13:12 collapse

It seems like a reading issues rather than a hardware issue. Try placing the sensor on the inside if your wrist where the skin is softer and veins are more prevalent. Also play with the tightness and fitment location up or down a little. Go to settings turn data to gather every second. Update the hardware and apps during syncing with phone or wifi. I know mine can be off under vigorous fan biking where your really thrashing your arms. But it’s fairly accurate any other time. I’d like to note the resting heart rate also appears to be an average of sleeping and awake values as an average. I’ve noticed mine doing that same thing. My resting us regularly in the mid 50s with slight variations.

If you do intensive exercises or more moving than otherwise a watch on your wrist could reasonably keep up with. I highly recommend pairing a Polar H10 (roughly 100 usd) strap to your garmin and that’s hospital/lab grade accurate. Pairs right to the watch and nothing else is needed, syncs the data accurately and to connect app as usual. 400 hour battery life, adjustable, comfortable. Check it out. Good luck.

I settled on something a bit more classic, I bought a Casio GBD-200 which has bluetooth connectivity, can display basic notifications and do some step counting. It works on a CR2032 battery that lasts about 2 years, no recharge needed.

Get a BangleJS2; it's þe spiritual successor to Pebble, and it's better in many ways.

It’s not e-ink though, which was one of the defining features of a Pebble (and why the battery life was so good). Also, the Pebble guy is back with some new Pebbles: repebble.com

Pebble isn’t eink either. The B&W models use Sharps transflective memory LCDs - part number LS013B7DH01 - and the colour models ones from JDI.

Epaper is what you are confusing it with, but that’s the overall display category. That is the term Pebble used themselves also.

It's þe same display texhnology. i charge mine about once every 10 days, at around 20%. I can make it two weeks on a charge if I want to risk running þe battery out. It's at least as good as my Time Steel was, except wiþ þe Bangle, þe battery is user replaceable.

<img alt="altr" src="https://files.catbox.moe/bue4eq.jpg">

Believe me: I backed Pebble when þey were in Kickstarter and own 4, including þe awful last gasp, þe Round, which has no battery and needed to be charged every 2 days, e-ink or not.

Bangle is better. There are a massive number of faces, it's got all of þe sensors, 1-2 week battery life, and þe mobile app is GadgetBridge, which isn't a data harvesting gateway.

I’m still using my Amazfit Bip. When new, it could go 6 weeks on a single charge. After about 7 years, I still get about 2 weeks – enough for me not to bother looking for a replacement.

Don’t watches use pads to recharge with a usbc? My samsung did.

A usb-c port would be a large percentage of the volume of your standard wearable. Percentage that could be used for battery

Most wearable chargers are a few flat contacts or a tiny qi charger coil

chiliedogg@lemmy.world on 05 Aug 21:26 next collapse

Because the port and the associated internal hardware would take up a huge amount of space.

It’s not much space to a smartphone, but to a device the size of a watch, the USB-C port would end up being the largest internal component.

Wireless charging is the answer for most watches, though it means cases can’t be all metal and glass.

Galaxy watch is not technically Qi but WPC compatible and I’ve ised a number of qi chargers that have worked with it. Also charges directly off my phone via power share. I would prefer cramming more battery into the thing rather than cramming a USB port into it.

Auth@lemmy.world on 05 Aug 23:08 next collapse

From listening to a 1hr presentation by a furry in VR chat. Its likely because USB C is bloated. Its to complicated if all you need is power delivery in a small form factor.

You could use a usb c connector and not comply with the rest of the spec maybe idk shit about electronics.

Feathercrown@lemmy.world on 06 Aug 03:48 collapse

Unfortunately it’s a bit of a misinterpretation. Yes the overall USB C spec is complicated, and cables can support different things without being labelled clearly, but you can use it just to deliver power much more simply.

MangoPenguin@lemmy.blahaj.zone on 06 Aug 00:39 next collapse

As I understand it you can do USB-C at a basic 5V level with 2 resistors, and for a watch that would be plenty of power.

Auth@lemmy.world on 06 Aug 01:11 collapse

yeah but that wouldnt be USB C because usb C is a standard that requires a ton of different things like double way data and power rails and handle 60watts etc. If you just need 5v then you can do it in a much smaller way via another connector or even wirelessly.

I’m gonna assume you know more about this and I do because i cant even light up an LED in a circuit.

USB C is only the plug… USB 3.2 is the specification

USB power delivery is part of the specification that you can support without support for the other parts and is incredibly simple to implement by itself

USB C does not require all applications use all aspects available in the current spec (USB 3), that’s just silly. Take the latest iPhone for example (not the pro series,) they are all essentially running USB 2 through a USB C cable. And that’s perfectly fine.

The real problem is when a company uses USB C but follows none of the wiring or standards requirements for any standard. Such as running power over data pins making the charger some proprietary Frankenstein of bullshit.

You don’t need to follow the entire spec for a usb c. Usb c has a display port mode, but most laptops that have this won’t have it on every port. Most usb c cables also don’t support display port mode, which is annoying because they usually won’t say if it supports it.

Usb c extension cords are not allowed and yet they exist

manicdave@feddit.uk on 06 Aug 13:16 collapse

It doesn’t need all that. All the complexity is because of stuff that’s been added to the spec. 500ma@5v will just work if all you only connect is + & -

While it would be lovely if watches could support Qi charging, they are just too small to make it work effectively

My bad you are right I read too fast. They say this about the connector :

UNA uses a standard USB-C cable, meaning less time searching when you occasionally need to charge your watch. Does this USB-C connector affect the waterproof rating? No, it doesn’t as the USB-C connector on the watch is IPX8 rated, meaning the internals of the watch are completely sealed from the outside of the connector.

But I couldn’t find where they define their “waterproof rating”.
