Apple Watch Series 6 and 7: all their similarities and differences — 2022

Apple Watch Series 6 and Series 7, Apple's top-of-the-range smartwatches in 2020 and 2021 respectively. Two devices that we already anticipate to you that share many characteristics, but that have some interesting differences worth analyzing. In this article we make a comparison of what one and the other offer, so if you have doubts about it, we recommend that you continue reading.

Comparison table: Apple Watch Series 6 vs Series 7

In each comparison we make, we always say that the technical specifications are not everything, since after all they are still pure data of which there is much more to say brought to real life. In any case, they are not less important for that and we believe that it is a good starting point to begin to know the similarities and differences between these two watches.

As we already told you, we will analyze some sections in more depth, but in summary you should know that these are the Main differences that we can already observe between these Apple Watch:

    Screen:Although the size of the devices themselves does not vary much, the screens do, with the Series 7 being the one that offers a greater diagonal. Colors:In this aesthetic section we see that, although they are not major changes, the Series 7 offers different shades to which one more option with the green color is added. Processor:really this is more a similarity than a difference as we will see later, but on paper it comes to be a different chip. Price:Although the Series 6 has been discontinued, it is still in some stores and, of course, at a lower price than the 429 euros that the Series 7 has to start with.

Few differences, although they exist

As you may have already seen in the table and we already anticipated you at the beginning of this post, there are few differences that we can find between these two watches. Although obviously there is some, since otherwise they would be the same watch. Below we analyze these differential aspects between both generations.

Screen, do you notice the increase in the Series 7?

Answering directly to the question, yes, the difference between them is noticeable. The Apple Watch Series 6 had already been offering a very interesting size inherited from the Series 4, which was the one that extended the diagonal and the Series 7 arrives perfecting this by reduce front bevels , giving a feeling of being in front of an infinite screen that rushes to the edges.

Series 6 (left) and Series 7 (right)

The main differences ultimately lie in the exclusive spheres of the Apple Watch Series 7. Some of them do have the Series 6, although it is in the most recent model where they have been made larger to take advantage of that screen increase. And in short, removing this, whoever wears a Series 6 without having tried the 7 will not notice anything strange, but there is no doubt that after trying the Series 7 it makes a more than notable difference.

They have other aspects in common

Now, where we do find no difference is in relation to how they look on a day-to-day basis. Although they have different resolutions, when dealing with such small screens, it is almost imperceptible. The content adapted to them looks fabled in both cases with a sharpness really remarkable and some colors that do not look exaggerated.

The fact that the panel they mount has LTPO technology, which allows refresh rates of 1 Hz while at rest, is what allows them to have the functionality Always On Display (display always on). This allows us to always see the content of the selected sphere or open application with a lower brightness and without this excessively affecting battery consumption.

They have a different chip

We were already seeing in the table that both start with a different processor, although we have to admit that this is a bit of a tricky difference, since we could have perfectly added this section to the similar section. Why? Well, because it seems that the name of these chips responds more to marketing strategies than to real changes.

In numerous tests carried out by experts in the matter, it has been possible to demonstrate that both chips are practically twins at a technical level. And although there is a difference in favor of Series 7, in the end it is something invaluable to the user. Because no, it is not noticeable even a little in the day to day.

Although all this is not necessarily bad. It is a chip advanced enough to offer a great performance on both clocks , allowing you to open applications very smoothly, carry out sports monitoring or health analysis very efficiently. They also fully comply with battery management, so in the end it is not something to blame either, although it is evident that it would have been appreciated if they had been called in the same way or at least very similar to know at first that they are almost identical chips.

Improved load times in 7

Although Apple did not count it as a fast charge back in the day, the Apple Watch Series 6 already had better charging times compared to its predecessors. However, the Series 7 does incorporate a fast charge Clearly, both officially on paper and in practice, yes, it has to be with a USB-C power adapter of at least 18w that accompanies the charger with the same standard that comes with the device.

The Series 7 is capable of charging 50% in half an hour. Or what is the same, fully charges the watch in 1 hour. This is something very interesting for those who are used to sleeping with the watch on to analyze their sleep, since it is possible to recharge it for a while before going to sleep (while you have dinner or take a shower, for example) and get enough charge for the night. and the next day.

With the Series 6, of which we already said that it did not have a bad load either, the times are somewhat lower. It usually recharges its battery from 0 to 100% in about 2 hours (probably a little less). These are good times in any case, although you will have to make sure to reserve more time for him in his base so that he can fully charge.

Back of Apple Watch, with charger

What both share in this section is the charger with proprietary standard from Apple, which prevents both watches from being charged with Qi wireless charging bases, which is the traditional charging method and which incorporates equipment such as the iPhone or AirPods. The charger of the Watch, which is the same as the first generation, has a small part that bulges downwards, which means that it cannot be recharged with other commercial chargers.

These are their many similarities

Although you have already seen that in previous points we shared the odd similarity in sections that a priori were differences, in the following we do fully analyze those points in which there are clear similarities. In some cases they even offer the same experience, so they would be identical specifications.

Compatible size and straps

Yes, the dimensions between one generation and another change. Also the diagonal of the screen, but… They come to be the same. The overall size of the box remains the same, so both can share straps . The strap compatibility of the 40 mm Apple Watch Series 6 is with the 41 mm Series 7, while the 44 mm of the Series 6 is with the 45 of the Series 7. That is, small with small and large with large.

This topic is important, since before the presentation of the Series 7 it was rumored that they would stop offering compatible straps. Although of course, so many things were rumored about this watch that in the end did not happen, which shows that the rumors are not always accurate. Be that as it may, you should know that, that the Apple Watch from the first to the last and including these two generations, can share straps without problem.

Same autonomy and insufficient?

We are not going to discover anything by saying that the battery is the weakest point of an Apple Watch. Whatever it is. It is true that there have been more than appreciable improvements from the first generations to the present day (it would only be missing). But this does not mean that for some it is still insufficient.

Beyond explaining the reasons why the low autonomy offered by these is justified, we believe it is more interesting to tell you how long they last in real environments away from tests carried out in laboratories. And we start with the conclusion and it is that, use it as you use it, the advisable thing is going to be whenever recharge it at least once a day .

There are many uses that affect the battery of both watches to decrease throughout the day. Such as having the screen on function enabled, doing a lot of workouts with the clock tracked, the number of health records you do, if you answer a lot of notifications from the clock... With intensive use you will get to the end of the day just right, but you will get there, hence it is rare that you run out of battery before bed.

Now, if the use is more measured, you can perfectly arrive with a 50% or more battery at night with any of them. Even with Always On Display enabled. This a priori is a good starting point to say that autonomy gives to a day and a half or two , but it is not entirely recommended, since in the end the next day you are going to be in a hurry and hence the advice to charge it every day.

Very interesting health sensors

The first thing you should know is that the Apple Watch cannot be considered a medical device. In other words, if you manage to detect an anomaly at the expense of the results it offers you, it is not binding to argue it as a medical test. Now, does this mean that it is not useful or effective? Absolutely.

There is a lot of news that we have received throughout these years in reference to how the Apple Watch has helped to detect certain heart diseases such as arrhythmias, insufficiencies, fibrillation... In these two cases we find watches capable of measuring the heart rate , perform electrocardiograms (with a bypass) and the blood oxygen level. All this data can be consulted later in the app Health of the iPhone.

In various tests carried out with tested medical devices, it has been proven that they are very effective watches in their results and offer very even and even identical data. But again we insist that they are not decisive, so it is advisable that if something strange is detected, go to a doctor to make a more exhaustive diagnosis.

Special mention for fall detection , very useful for older people in particular, but of all ages in general, as it can be of vital importance in situations such as sports accidents or even slips at home. It is a function that allows you to configure an emergency call that in some cases has saved a life, although we hope that you never have to use it.

Sports tracking for many activities

One of the most interesting challenges of owning an Apple Watch is accepting your daily challenges of close the rings . Both the Series 6 and 7 maintain this essence introduced in the first generation and force you to get up once every hour to avoid a sedentary lifestyle, practice some sport for at least 10 minutes a day and burn at least 300 calories.

For the rest, it offers the possibility of monitoring while you practice many sports. From walking, which can be useful even when you are on your way to a routine errand like shopping, to dancing or watersports . All this through the native Entrenos app that comes pre-installed. And the data related to your training is available in the app Fitness on the iPhone (formerly known as Activity).

And we highlight this water sports because, as you saw in the table, both are submersible to 50 meters deep . Therefore, this is an interesting point to know also in order to be able to take a shower without a problem with the watch or put it in a pool, although we recommend that you put the water mode that appears in the control center to avoid accidental touches and be able to expel the liquid inside afterwards.

Frequently asked questions and conclusion

Regarding this comparison, although we have already dealt with all the important aspects, it is likely that you will have some doubts. In the following sections, and by way of conclusion, we will answer these questions so that you are totally clear about our position and recommendation.

If you have the Series 6, is it worth the jump to 7?

We don't think we have the right to tell someone that they should or shouldn't buy a device if they feel like it, but trying to be objective, we don't think so. The passage from one generation to another is an interesting change at the screen level and with the point of fast charging as an interesting plus, but of course that They are not changes that make it necessary or that you will notice a huge difference in terms of performance.

If what you want is resize , going from having the small Series 6 to the large Series 7 (or from the large Series 6 to the small Series 7) can be an interesting change because we understand that you have a compelling reason for it. But in the same way, to tell you that except for the size, the change in other aspects does not seem very justified. They are two practically brothers watches and it is that even the Series 7 could have been called 'Series 6s' perfectly.

What to do if you don't have any

If you don't have any of these watches, things do change because your starting point is to have a Series 5 or earlier or even not have any. It is not that from a Series 5 you are going to notice a brutal change, but it is already more considerable and the Series 7 can be a good replacement. Although from our perspective, we believe that the minimum change should be from a Series 4 or earlier .

And if you don't have any, well hey, going for the latest model doesn't seem too bad. If you find a great offer for the Series 6, maybe you should think about it, but first we think that debuting in the world of watchOS with the Series 7 is an excellent choice.

Where to buy them (also the Series 6)

As we said, the Apple Watch Series 7 is for sale in Apple stores, both physical and online. It can also be found at other dealers. However, the case of the Series 6 is more special, since Apple discontinued it and it is officially not for sale. However, it can still be found in stores like Amazon at really interesting prices and with full guarantees of originality and with 2-year coverage.

Apple shows that change is not necessary

As a general rule, updating the same range of device once a year is usually not recommended because major changes are not usually found. Although it is true that in the case of the iPhone it may be justified at times, Apple has shown that this is not the case with its watches. Throughout its history we have been seeing little changes every year that on occasions like these two Watch are really rare.

There are two general recommendations. The first is that you renew your watch only when it stops working and the other, which seems opposed to that, is that you buy the one you want when you feel like it. Just missing. But if you really want to experience a remarkable change when buying the new one, it is recommended change it every 3 years at least , so you don't feel like you're always wearing the same device on your wrist.
