Samsung Galaxy Watch 4 release date, price, news and leaks

While the Samsung Galaxy Watch 4 is possibly going to be the next big smartwatch from Samsung, we're not totally sure about that, as the Galaxy Watch Active 4 could be next - or they could come together.

The latest news suggests Samsung's two wearable lines, which have previously alternated in release, could launch together in 2021 with big differences to make sure the Galaxy Watch 4 and Watch Active 4 are sufficiently different.

In fact there's now talk that the Watch Active 4 is actually the Watch 4 – and that the device we're talking about here is going to launch later with a different name.

This is just the latest of plentiful leaks and rumors that have emerged about the next top-tier Samsung smartwatch, and you’ll find them all below. Then further down you'll find our wish list of all the key improvements that we want from the Samsung Galaxy Watch 4.

From features that actually work on day one to a better app situation, there's a lot that could be improved for Samsung's next smartwatch, as you'll see below. There are a host of things that we wished were better on the Samsung Galaxy Watch 3, and we outline what's left to improve on the new smartwatch.

We've also included an educated guess at when we’re likely to see the Galaxy Watch 4 – and what it might cost.

Cut to the chase

What is it? The next top-end smartwatch from Samsung
When is it out? Perhaps August 3, maybe earlier
How much will it cost? We're not sure, but probably a lot

Samsung Galaxy Watch 4 release date and price

The Samsung Galaxy Watch 3 was announced on August 21 of 2020. There wasn’t a Galaxy Watch 2, but the Samsung Galaxy Watch Active 2 was announced on August 5 of 2019, and the original Samsung Galaxy Watch was unveiled on August 9 of 2018.

With all that in mind you would think that the Samsung Galaxy Watch 4 will be announced in August of this year. However, the latest leaks to hit the web suggest it'll be in the second quarter of 2021, so April, May or June.

That's also in line with a leaker who in early May claimed the wearable was "coming soon."

On the other hand, the most recent leak hints that August 3 is going to be the big day – and that the Galaxy Watch 4 will appear alongside the Galaxy Z Fold 3 and Galaxy Z Flip 3, among other devices.

Whenever it’s announced, it will probably be another two weeks or so from then to when it’s actually released, so don’t expect to have the Galaxy Watch 4 on your wrist before late August.

As for what the Samsung Galaxy Watch 4 might cost, there aren’t any rumors there yet, but it might well be similar to the Samsung Galaxy Watch 3, which starts at $399 / £399 / AU$649 for the smaller 41mm model, and $429 / £419 / AU$699 for the larger 45mm one, with the price rising in both cases if you want LTE connectivity.

News and leaks

One big Galaxy Watch 4 leak is that it might run Wear OS rather than Tizen. That comes from Ice Universe (a leaker with a decent track record) who claims that Samsung's "new watch" will switch to Android (presumably meaning Wear OS).

That rumor has been backed up by a second leak, which suggested the lack of a Tizen app store was the reason Samsung was ditching it.

Of course, even if they're right they don't mention the Galaxy Watch 4 by name - it's possible that the new watch in question could be a new Galaxy Watch Active model.

However, there's growing evidence that some Samsung smartwatch will run Wear OS, as mention of a device codenamed 'Merlot' has also been spotted alongside the words Wear OS in Samsung source code.

Elsewhere, SamMobile has also said the Galaxy Watch 4 will run Wear OS, but added that it will be overlaid with a new version of Samsung's One UI, leading to an interface that looks similar to the one on previous models, despite the operating system change.

The site also claims in the same report that the Samsung Galaxy Watch 4 will have a walkie-talkie feature and a rotating bezel.

Our biggest hint yet that Wear OS could be on board comes straight from Google, which has announced that it has overhauled Wear OS with Samsung's help, so we'd think it's very likely that the Galaxy Watch 4 will run the new software.

We've also heard the Wear OS claim from another source, who adds that the Samsung Galaxy Watch 4 will have a similar design to its predecessor, complete with a rotating bezel, and that it will be available in the same colors as 2021's "Galaxy Z."

That last bit is deeply unclear, both because no Galaxy Z models have launched yet this year, and because it's not clear whether they mean the upcoming Galaxy Z Fold 3 or the Galaxy Z Flip 3.

However, rumored colors for those phones include black and green for the Fold 3, and black, beige, green, and light violet for the Flip 3.

In other design news, we could see the Galaxy Watch 4 have to change its shape and size to accommodate batteries from a new supplier. It's yet to be seen if there are any benefits to the battery being changed, though it's most likely part of an agreement between Samsung and ATL - who partnered up in 2019 again after the companies cut ties in 2017 over Galaxy Note 7 fires.

Speaking of the battery, a certification listing out of Finland mentions a 247mAh battery. That's the same size the 41mm Galaxy Watch 3's battery, and suggests that the larger Galaxy Watch 4 will also match its predecessor at 340mAh. The listing also mentions 5W charging.

One rumor also suggests an upcoming Samsung Galaxy smartwatch will have a glucometer, for measuring the blood sugar of the wearer. It's not clear if this is for the Galaxy Watch 4 or Galaxy Watch Active 3, or both.

Another leak explicitly states that the previous one is wrong, though and that the Watch 4 won't have a glucometer, so maybe it won't.

Another rumored health feature is a BIA (bioelectrical impedance analysis) sensor, which could allow the wearable to measure your body fat and muscle mass. Only one leaker has talked about this so far, but there aren't any conflicting reports, so it's certainly possible.

We've also heard that the Samsung Galaxy Watch 4 may come in 42mm and 46mm sizes, both of which are 1mm bigger than the options on the Galaxy Watch 3.

It might have a major power boost too, as the Samsung Galaxy Watch Active 4 is rumored to have a powerful new 5nm chipset, and if the Active 4 has that we'd expect the standard Samsung Galaxy Watch 4 would as well.

Beyond all that, there are a few things that we can predict. Based on previous models it’s likely that the Galaxy Watch 4 will be available in two different sizes, optionally come with LTE, and in all cases come with a heart rate monitor, an ECG, GPS, and a circular AMOLED screen.

It will also almost certainly come with a variety of exercise and activity tracking features, along with a swim-safe build.

Samsung's Galaxy Watch 4 switching to Wear OS doesn't make sense right now

What we want to see

As excellent as the Samsung Galaxy Watch 3 is, there’s always room for improvement, and we think Samsung would do well to start with the following five things.

1. Better battery life

Battery life is a problem with a lot of smart devices, and the Samsung Galaxy Watch 3 is no exception. While its life isn’t terrible, it does need charging every two to three days in our tests.

Worse still, the size of the battery and the life it delivers are both actually a step down from the original Samsung Galaxy Watch, so for the Samsung Galaxy Watch 4 we want to see a return to form, with a battery that can go four to five days between charges.

That might be tricky while keeping the wearable slim, but if any company can do it it’s one with the resources of Samsung.

2. A lower price

With a starting price of $399 / £399 / AU$649 and a price of $479 / £459 / AU$849 for a 45mm model with LTE, the Samsung Galaxy Watch 3 is far from cheap. In fact, its starting price is higher than that of an Apple Watch 6 in many regions, which seems excessive.

So for the Samsung Galaxy Watch 4 we want a lower starting price, perhaps more in line with the original Galaxy Watch, which started at $329 / £279. At the very least though we really hope Samsung doesn’t further push the price up.

3. ECG and SpO2 out of the box

The Samsung Galaxy Watch 3 is packed full of health features, including an ECG (electrocardiogram), blood pressure monitoring, and an SpO2 monitor for detecting sleep apnea, but none of them were available in all regions at launch.

That’s because these features each need certifying by regulatory bodies in most countries before being activated in them, but it was a shame to have a premium product where many of its advertised features didn’t initially work.

So for the Samsung Galaxy Watch 4 we want these features to still be included, but we want them all to be active everywhere on day one.

4. More apps

For its Galaxy Watch wearables Samsung has opted to use Tizen, rather than Wear OS. That’s not entirely a bad thing since Tizen has a lot to like about it, but one area where it struggles even more than Google’s smartwatch operating system is apps.

As well as only offering a rather limited number of apps, it also lacks some of the most useful smartwatch ones, such as Google Maps.

We’d love to see this situation somehow improved for the Galaxy Watch 4, whether it’s through Samsung somehow incentivizing developers to bring more apps to its device, or producing more and better apps of its own to make up for the omissions.

5. A new chipset and more RAM

Smartwatch specs don’t move on as fast as smartphone ones do, which is why the Samsung Galaxy Watch 3 uses the same chipset as the original Galaxy Watch. Not only that, but it also has less RAM (at just 1GB) than the LTE version of the first Samsung Galaxy Watch.

While performance is solid, it’s definitely time Samsung improved both the chipset and RAM situation, so we want a new one of the former and at least 1.5GB of the latter in the Samsung Galaxy Watch 4.
