Comparison Apple Watch Series 4 vs Apple Watch Series 7

What benefits do they have?

Before I go into depth to talk about all the differences that I have found between these two Apple Watch models, I want you to know what are the main differences that you can find between them, since later I will go into much more detail on what these differences are based and above all, how they affect the user experience that you can have with one watch and another.

You already know what are the differences between the Apple Watch Series 4 and the Apple Watch Series 7. On paper it does not seem that the jump is really striking, however many of them have a much greater impact on the experience you have with it. device than you can imagine by simply reading the data. Next I will tell you which are the ones that, from my point of view, can have the most impact, before going fully into them later.

• The screen is undoubtedly a differential point, both for its size and for the presence of Always ON technology.
• If the Apple Watch stands out for something, it is because of the health-level functions it provides, and there the different sensors that one model and another have take center stage.
• The processor change is also noteworthy, although for practical purposes a huge difference is not noticeable, it does mount a different chip at the end that is worth noting.
• The fast charging of the Series 7 is a tremendous convenience, especially for users who use the watch to monitor sleep. I’ll tell you in more detail a few lines below.

Main differences

How have you been able to verify with the comparison table, between the Series 4 and the Series 7 there are certain points where the user will notice certain improvements. However, there are aspects that are obviously more important than others, especially when it comes to providing that feeling of real change between one device and another. And that’s right where I’m going to start comparing both Apple Watch models.

The screen improves considerably

Surely the highlight and what changes the most from one model to another is the screen, especially since it will be what you notice the most on a day-to-day basis due to different factors. The first of them is its size , since in the Apple Watch Series 7 the screen is 45 or 41 mm while in the Series 4 it is 44 or 40 mm , that is, in a box of the same size Apple has used the screen more in the Series 7. Actually the increase is 1mm, and surely you can think that in functional terms it is not usable or it is not noticeable on a day-to-day basis, but the reality is quite different, especially if you use the spheres adapted to this new screen size, although I will talk about the spheres in detail later.

When talking about the screen, I obviously have to mention the Always on Display technology that makes the Apple Watch screen always on. With the Series 4, when you turn your wrist or spend a while without using the watch, it turns off, it turns completely black, however, with the Apple Watch Series 7 this does not happen, since what Apple has done, and that has been implemented since the Series 5, is that the colors of the dial are dimmed to reduce battery consumption, but you can continue to see the time at all times and the rest of the information displayed by the dial . Without a doubt, it will be one of the functions that you will enjoy the most in the jump from Apple Watch Series 4 to Series 7.

Finally, you also have to know that Apple has not only increased the size of the screen, but that it has made it much harder than in previous models. For this they have managed to make the front glass up to 50% thicker , they have even been able to redesign it with a new flat base that makes it much more solid and shock resistant. But be careful, this does not mean that it will scratch less easily, so in that sense you will have to continue taking special care with the screen of your Apple Watch.

What sensors do they have?

One of the biggest attractions of the Apple Watch is the health functions that they are able to offer to all users, and in order to offer them they need to have a series of sensors. Well, the number and type of them is another of the great differences that you can find between these two devices. Here is a list of those that have both models.

• Apple Watch Series 4
  • Electrical heart rate sensor.
  • Optical heart rate sensor.
• Apple Watch Series 7
  • Blood oxygen sensor.
  • Third generation optical heart rate sensor.
  • Electrical heart rate sensor.

How can you check, not only does it have more sensors, but the common ones, in the Apple Watch Series 7 an evolution is present to provide the most reliable measurements possible. In both models you will be able to control your pulse and even carry out electrocardiograms whenever you want, but in addition, in the Series 7 you will also be able to know at any time what your saturation is, that is, the level of oxygen in your blood that you have. The reality is that it is incredible how the Apple Watch has become a technological device capable of monitoring people’s health, reaching the point of even saving the lives of many of them thanks to its measurements.

Along with these sensors, both models also enjoy the ability to detect falls , so that you can call both your contacts and the emergency services if the fall you have suffered has left you unconscious or makes it impossible for you to be the one who asks. help. This, together with the sensors that I have previously mentioned, have made many people save their lives in recent years.

Fast charging, can you tell?

Something that Apple Watch users have been asking Apple for a long time is to provide these devices with a greater capacity, so that in this way we can not worry about putting the watch to charge practically every day. Surely due to the size of the Apple device itself, at the moment it has not been able to offer a greater autonomy to its Apple Watch, however, what it has done is to increase the charging speed of these, and this between the Series 4 and the Series 7 is quite noticeable. Here are the loading times for both devices.

• From 0% to 80%:
  • Apple Watch Series 4: 90 minutes.
  • Apple Watch Series 7: 45 minutes.
• From 0% to 100%:
  • Apple Watch Series 4: 120 minutes.
  • Apple Watch Series 7: 75 minutes.

As you can see the difference is quite large , however, in this case I have to make a point regarding the fast charge of the Apple Watch Series 7, and that is that in order to enjoy it, users have to purchase a power adapter of at least 20W of power and use the charging cable that comes inside the box , otherwise the charging times of the Series 7 will be slower. And maybe you can think, “so if I use that cable and that power adapter also with the Apple Watch Series 4 maybe it will also charge faster”, well, I’m sorry to say no, this fast charging function is only available for the Series 7.

Aspects that you have to take into account

I have already told you about the points in which I think you will notice the difference between the two devices the most, above all, because personally they have been the news that I have noticed the most and I am noticing in that jump from Apple Watch Series 4 to Series 7. However , This is not here, and as I told you at the beginning of the post, there are several points in which Apple has evolved this product very positively, although perhaps on a day-to-day basis you may notice it less than those mentioned so far. We go with them.

Same battery

Unfortunately, at the autonomy level, the reality is that you will not practically notice the change. This is undoubtedly one of the points in which Apple has a lot of room for improvement with the Apple Watch, hence it has had to resort to fast charging in the Series 7 to somehow satisfy users. Obviously, the autonomy it grants is not bad at all, it is more than enough to complete a full day, however, what many users ask is to be able to forget to connect the watch to the charger for at least 2 days. To our chagrin it seems that this wish is far from being fulfilled. Below you can check the autonomy of both devices.

• Apple Watch Series 4: up to 18 hours.
• Apple Watch Series 7: up to 18 hours.

What about the spheres?

Obviously, the Series 7 by having a better used screen, Apple has been able to give the opportunity to all users of this watch to have spheres that are capable of taking advantage of that extra size with respect to previous models such as the Series 4. It is true that, at the moment, there are not many types of sphere that differ from one model to another by providing more information is the complications, but the existing ones are undoubtedly a very positive point for the Series 7.

In total, there are two areas that we have to highlight in this section. On the one hand, the one that changes slightly with respect to previous models, which is the Modular duo , since in the Series 7 it gives Apple the possibility of introducing two major complications, one below the other, unlike the Series 4 or models like the Series 5 and Series 6 where this is not possible. The other sphere is the Contour, which in this case is exclusive to the Apple Watch Series 7 and which, without a doubt, feels really good on this watch.

Different colors

If I focus on the aesthetics of the device, it is true that when the screen is off, we are really facing two traced watches, or at least that is what it seems at first glance, but the reality is that after many years in which Apple has kept the color palette of the Apple Watch, adding some in certain models, with the Series 7 it has changed completely. Here is the list with the colors available for both Series 4 and Series 7.

• Apple Watch Series 4:
  • Silver.
  • Space Gray.
  • Gold.
• Apple Watch Series 7:
  • Midnight.
  • Stellar white.
  • Green.
  • Blue.
  • Red (PRODUCT RED).

As you can see, the space gray and silver colors of the Series 4 have changed to midnight and stellar white respectively in the Series 7 , a change that in the case of midnight, I personally appreciate, since it is a much darker color. In addition, to the PRODUCT RED and Blue , which were already present in the Series 6, we must add another of the novelties, which is the Green color in a darker hue that makes it very elegant.

This is my experience after the change

After having told you the most important differentiating points that exist between both models, finally I want to end this post by telling you my personal experience after having made the leap from Apple Watch Series 4 to Series 7 . I have been a user of the Series 4 since the day of its launch, and the reality is that the performance it has provided me has been unbeatable, since three years later it was still performing just as well, even at the battery level, however, the cluster of functions that the Apple Watch has accumulated from the Series 5 to this Series 7 made the idea of exchanging one watch for another attracted me.

After more than a month with the Apple Watch Series 7, I can certainly say that the change has been worth it, but before I tell you why, I want you to know how I use this Apple device . It is literally a watch that I wear continuously on my wrist, since the management of notifications with it is really comfortable, as well as the fact of being able to measure physical activity at all times with its different sensors and rings that it provides to users, in addition of using the Train app to record my workouts each day. Sleep monitoring is another feature that I always use on the Apple Watch, so obviously I wear the watch while I sleep. In addition, for me the Apple Watch is also a fashionable element , and the variety of spheres it has and the level of customization that can be applied to them is key to be able to adapt its aesthetics to each moment or situation.

For this reason, the two novelties that I am noticing the most and enjoying on a day-to-day basis are, first of all, the screen . Although in theory the brightness is the same, the reality is that my perception is that everything looks much better in this Series 7, not to mention having the screen and the information present on it always visible, something that I highlight even more so in training moments where I don’t have to turn my wrist abruptly to see what progress it is.

As I told you, I use the Apple Watch to monitor my hours of sleep, so having the fast charge of this Series 7 has been a tremendous change . With just a few minutes of charging before sleeping I have the watch 100% and ready to use it both that night and the next day. This charging speed gives you the peace of mind of knowing that when you need an energy boost from the watch, with just a few minutes you can have a good autonomy.

In my case, the color I chose was midnight , and it is without a doubt the best choice I have been able to make. As I have told you, for me the Apple Watch is also a fashionable element and this case color is infinitely more elegant than the space gray that we had so far. Both to combine with different straps, as with the garments that you wear in your day to day, aesthetically this Apple Watch Series 7 in midnight color is, at least personally, much more beautiful.

Finally, and as you can foresee, for me the jump has been very worthwhile, since the accumulation of functions that the Apple Watch has accumulated over the years seems interesting enough to me to notice that generation out of the box. between Apple Watch Series 4 and Apple Watch Series 7.
