Although the new and improved software that comes with the watches is (probably) the most differentiating factor between the Samsung Galaxy Watch 4 and the Galaxy Watch 3 , the reality is that the difference is barely noticeable. In this sense, Samsung has achieved the incredible feat of integrating its own One UI interface into Wear OS, something that regular Samsung users will feel identified with.
But this is not all, far from the similarities in terms of navigation, this merger between the two operating systems brings more things. From a greater variety of Apps to access to the Google Play Store . In fact, if you have an App installed on your phone that has its version for Wear OS, you can synchronize it with your Galaxy Watch.
On the other side of the scale and in a more compromised situation is the Samsung Galaxy Watch 3 with its Tizen operating system. And what’s wrong with this? None if you don’t compare it with the new Galaxy 4 Classic, since the Galaxy 3’s selection of Apps is more limited by relying on Samsung’s Galaxy Store. Something that will not affect you in the short term, but in a couple of years when the developers stop updating their apps for this operating system.

Voice assistants and payments
Another of the great advantages and improvements of the evolution of Tizen to Wear OS has to do with voice assistants. And it seems that Samsung has reconsidered, now incorporating Google Assistant natively into the new Samsung Watch 4 . Because although it was also available with the Samsung Watch 3, the reality is that it caused quite a few problems, something that should not happen with the new operating system.
Another of the great advantages of the change towards a more Google-Friendly environment is the new facility that we will have to make payments with our smartwatch (thanks to NFC). While in the Galaxy Watch 3 we only had Samsung Pay, in the new Samsung Galaxy 4 Classic we can also have the Google Pay system.
Compatibility and updates
An important aspect that you should keep in mind when it comes to the Samsung Galaxy Watch 3 and the Galaxy Watch 4 Classic is that the former is much more affordable than the new Samsung smartwatch. The downside of this (because there always is) is that this model will never receive the Wear OS update , despite Samsung’s promise to continue incorporating security and performance patches for three more years.
How can the Galaxy Watch 3 overcome this situation? Well, thanks to a small compatibility detail that can tip the balance a lot in your favor. And it is that the Galaxy Watch 4 does not work with iOS , so iPhone users will not be able to synchronize their phone with the clock functions. Something that without a doubt makes you lose 50% of the potential of the smartwatch.
One of the great novelties that this Samsung Galaxy Watch 4 Classic brings compared to the Galaxy Watch 3 is its BioActive sensor. And what does it do? Well, through two electrodes integrated into the side of the watch, you can measure the composition of your upper body and thus approximately calculate your body fat composition, as if it were a portable scale!
In this way, the Galaxy Watch 4 takes a turn towards the world of fitness and allows anyone to know their body fat percentage, muscle mass, water content and more details just by turning the wrist. Keep in mind that these data are approximate, but they also allow us to get an idea of our state of health.
Almost like any other smartwatch, both models, Galaxy Watch 3 and Galaxy Watch 4, offer the possibility of monitoring the quality of our sleep. The novelty that the Samsung Galaxy Watch 4 brings with respect to the Galaxy Watch 3 is the ability to continuously measure SpO2 , something really useful for diagnosing nocturnal respiratory problems. Such as snoring, which can also be recorded automatically.
Battery life has always been one of the biggest criticisms that high-end smartwatches have had, and especially the Galaxy Watch 3. And if you put the watch to good use, you will have to end up charging it every day . Something that we are already used to with our smartphones, but it is something that we cannot allow in a smartwatch, especially if we intend to use it to monitor our quality of sleep. Something that in the Samsung Galaxy Watch 4 is supposed to have been improved, although the reality is that its battery is still somewhat poor.
Also, as is typical of Samsung smartwatches, none of these include fast charging support . And it is that according to the company, just 30 minutes of charging are enough to power the smartwatch battery for up to 10 hours of passive use.
Another difference between the Samsung Galaxy Watch 3 and the Galaxy Watch 4 is the screen. Although do not expect too much because the new models incorporate slightly improved screens . Although AMOLED panels are still used, resolutions have increased slightly. Something that in reality is only noticeable a little in the larger models. What is noticeable is the improvement in the glass of the screen, which becomes a “normal” Gorilla Glass DX to a DX +, which gives it a plus of resistance.
Conclusion: Galaxy Watch 3 or Galaxy Watch 4?
In theory, the Samsung Galaxy Watch 4 Classic offers an interesting package of new improvements and features, especially thanks to its new operating system. If you want to buy a next-generation or high-end smartwatch, going for the Galaxy Watch 4 is a safe bet . Unless you have an iPhone or are on a tighter budget. In that case, the Galaxy Watch 3 is an equally brilliant and powerful option, with the flaw of the lack of some new apps and the expiration date of 3-4 years of its operating system.
