Between the Apple Watch Series 4 and the Apple Watch Series 5 there is only a year difference, so it is clear that the changes between one and the other are not very large. However, there are details that can make a difference, although everything will depend on the point of view of each user. Therefore, in this post we are going to tell you everything about these two Apple Watch models.
Characteristics of both models
The first thing we want to do before getting into the comparison, in which we will deal with both the differential points between them, as well as those aspects that they share and that, obviously, also affect the user experience of the users of these two watches, is tell you what the technical characteristics of both teams are. In this way you will be able to understand much better the comparison that we made in this post. Below is a table with all the information.

Main differences
Now yes, once you know all the specifications or technical characteristics of both the Apple Watch Series 4 and the Apple Watch Series 5, we are going to start with the comparison, and we do it by talking about the main differences that can be found between them. As we have mentioned before, there are not many points that separate these two Apple watches, but the existing ones can make a difference for certain users.
Screen
We started strong, and it is that the screen of these two models is surely the most differentiating point between them , and ultimately, what can make some users of the Apple Watch Series 4 be encouraged to make the leap to the Series 5, or those potential buyers who are hesitating between these two, opt for the latest option. The first thing you have to know is that the screen sizes are exactly the same , both Series 4 and Series 5 have two models, one 40mm and one 44mm. The screen difference between both devices has not meant a quantitative and qualitative difference between both versions, so, in case the screen is damaged or broken, it is recommended that we take into account whether or not there is a difference in the costs of repairs.

The panel type is also shared by both models, being a Retina OLED display with Force Touch . However, the Apple Watch Series 5 has a key feature, since it is the first model that has the Always On screen or always on screen . This means that with the Series 5 users will have the Apple Watch screen always visible, without the need to touch it or turn the wrist to activate it and know the information on it.
It really is a great change, especially when using certain applications such as the training one, since you will be able to view the information that it is collecting at all times. In addition, you will also be able to see your spheres whenever you want, since the screen will always be on. Now, all that glitters is not gold, so pay attention to the rest of the points in this comparison because this Always On screen of the Apple Watch Series 5 affects another of the most important points when talking about a smartwatch.
Sensors
One of the most outstanding points of the Apple Watch are the functions at the health level that it is capable of providing to all users who are lucky enough to be able to enjoy this device on a daily basis. As the generations go by, there are more options that Apple provides, and all this is to blame for the sensors that each Apple Watch model has. In the case of the Apple Watch Series 4 and Series 5, the difference at the level of sensors is very small, but there is a small evolution in the Series 5 that is not present in the Series 4 and that, as well as a function present in Both models that, since their implementation, have been very helpful in saving the lives of many users, but let’s go in parts.

In the first place, the number of sensors does not vary from the Series 4 to the Series 5, but there is a small evolution, and that is that although both have an optical heart rate sensor and an electrical heart rate sensor , the optical one of the Series 5 is second generation, while Series 4 is first. But as we said, the great function present in both is the presence of fall detection . This functionality allows the Apple Watch to be able to call both your contacts and emergency services at any given time.
The way fall detection works is that, at the moment the Apple Watch detects a strong fall, it sends you a notification asking if everything is okay, in case you answer yes, the Apple watch will not It will do nothing, however, if you answer negatively or even do not answer for any other reason, it will be the Apple Watch who will notify your contacts and emergency services so they can help you. As we have mentioned before, this function has already served to save many lives and of course it is something that you have to value, especially those users who usually do sports activities that may entail a risk of falling.
Storage capacity
Let’s go with the last difference that can be found between these two Apple Watch models, and it is its storage. This has been increasing as the generations have passed, well, from Series 4 to Series 5 there has been a new change since the Apple Watch goes from having 16 GB to 32 GB , an improvement that means doubling the capacity of the device .

Actually, this improvement does not have much impact on the use that can be given to this device, it will simply allow you to have more saved files such as music or photographs inside the clock. Specifically, it is in this first aspect where you can notice the difference, since now users who use their Apple Watch to go running or practice any sport without having to carry the iPhone will be able to download much more content to it than before .
Common aspects
Once we have already discussed the aspects that differentiate the Apple Watch Series 4 from the Apple Watch Series 5, we also have to talk about the points where forces are equalized and, obviously, also affect the user experience provided by these two devices.
Design
One of the points where there is no difference and that, in addition, is obvious as soon as you put one watch in front of another is the design. In fact, the Apple Watch Series 4 marked a before and after , since it has been the model that has “broken” with the design that the Apple Watch has carried since its first launch.

Both leave behind the marked and square frames that the first models had, betting on somewhat more rounded lines, which also take more advantage of the screen and, consequently, give the user a larger screen than the previous 38 and 42 models. mm. Another point where they also coincide is in the available colors, being the following:
- space gray
- Silver.
- Prayed.
Battery
Finally, we have to talk about the battery, which is a fundamental point when evaluating practically any technological device, but even more so in a smartwatch. The reality is that neither of the two models is left over, that is, you will have enough autonomy to spend the whole day using the functions offered by this device, however, to endure another day you will have to spend yes or yes through the charger .

However, and now we continue with the point that we left open when we talked about the Always On screen, you have to know that the Apple Watch Series 5 offers a somewhat lower autonomy with this function activated, however, if you deactivate it, its performance is slightly superior to that of the Series 4. Therefore, you will have to choose between enjoying a function that is very useful as well as attractive, or a somewhat greater autonomy than usual.
Which one are we left with?
Whenever at ITIGIC we carry out this type of comparison, we like to end it by telling you what our point of view is, that is, giving you our subjective opinion. However, if you are in the position of having to choose between these two models, we encourage you to be yourself or yourself who decides which of the two models is more suitable for you based on your needs and what they offer. .
For all those users who already have the Apple Watch Series 4 , under no circumstances is it worth changing it for the Series 5, since the news, as you have seen, are really scarce. Now, for the rest of the users who come from a model prior to the Series 4, or one of these two is going to be the first Apple Watch they have, without a doubt the best option is the most recent, that is, the Series 5 already that they will be able to enjoy a more satisfactory experience given the set of functionalities that it offers.
