Galaxy S8 vs S7: is it worth updating? In-depth comparison

Galaxy S8 vs S7: is it worth updating? In-depth comparison

I've already had the Galaxy S8 + for about a month as my primary phone and as most of you blog readers know, the S7 Edge was my primary Android phone throughout 2016. After using both phones for a good period of weather, How does the Galaxy S8 vs S7 compare? Is the upgrade worth it? And if you plan to buy one, is it worth investing in an S8, or is it better to buy an S7 Edge?

To answer these questions, we are going to separate the article into multiple important categories of the smartphone, and see how much the S8 + stands out or stands out against the S7 Edge in each of them.

It should be noted that the differences in hardware between the S8 + and the S8 is limited only to the size of the phone; Unlike last year, where only the S7 Edge showed a curvature while the S7 was completely flat, here both teams have a curvature on the screen.

Note: I updated the S7 Edge to Android Nougat (7.0) and I did a Factory Reset (I configured it as new) to have a fairer test.

Looking only at the hardware in both computers, we can see that there are not many differences in terms of performance power. And indeed, side by side, both phones behave almost identically when it comes to running apps, games and others. It is something that we can even notice in the way that Samsung has named its new chip Exynos (8895), versus the 8890: it is not such a significant jump in performance. Which is not a negative point, however: both S7 Edge and S8 + can run all Android apps without any problem.

Where we see a wise decision by Samsung, is to give us 64 GB of base storage on their phones, instead of 32 GBs. A high-end phone, in my opinion, should already come with 64GB of minimum internal storage. Just by installing my base apps, and with the size of Android, I usually have about 8 Gigabytes free, nothing more, on a 32 GB phone, leaving very little space for videos, photos, or any game I want to try. With 64 GBs, the storage issue is no longer a latent problem, so it seems like a wise move by Samsung.

On the other hand, we have the issue of battery – which we will detail later – but let me tell you that although there was a reduction of 1oo mAh, it was not noticeable in daily use.

The S8 + outperforms the S7 Edge, but only slightly in performance.

Industrial Design and Screen


The S7 Edge was beautiful – the hottest phone of 2016, IMO – but putting it next to the S8 + makes it look dated. The S8 + is the most beautiful phone I've seen so far, really worth admiring. The way in which the Infinity Display seems to blend in with the rest of the design making all content look much more immersive. The way the screen curves around its edges, and how it reduces the bezel as little as possible to remain comfortable, is a real leap in design.

The S7 Edge is still a nice phone, but the S8 + leaves it far behind; a fairly significant evolution.

Also, the S7 Edge has a significant design error that I mentioned even in my S7 Edge article 6 months later: the paint on the S7 Home button tends to fade, even with routine use. The touch of keys, or any object that we may have in our pocket end up scratching and, eventually, depainting. It is not a very serious problem for black models, but the silver color that I have already shows serious wear and tear, which plays a rather negative role in the design of the S7 Edge.

Another thing worth noting in this regard: forget about tempered glass or screen protectors. Due to the curvature of the S8, S8 + and S7 Edge, it is almost impossible to create a screen protector or tempered glass for these phones. There are some models that only glue the edges, which leaves a gap in the middle of the screen and makes it extremely uncomfortable to use. There are also plastic protectors, but they make touching the screen an unpleasant experience. After searching for alternatives for my S7 Edge, I resigned myself to using it without tempered glass and let me tell you that it has held up quite well this year of use. It only has a scratch, but it's because I fell face-first onto the pavement on a trip to Tarapoto. Apart from this, I have used the phone without a tempered glass and it has kept up super well. I have done the same with the S8 + and s, I have dropped a couple of opportunities but, so far, it shows no scratches. So if you are one of those who usually protect your phones to the maximum with tempered glass, this phone is not for you, nor is the S7 Edge. But if they can live without one, then they will have no major problems, since I have not noticed small scratches after continuous use.

In design, the S8 + is the clear winner


Samsung continues to leave its rivals far behind when it comes to screen quality. The screen of the S8 + is brighter than that of the S7 Edge, but only minimally. What I did notice is that the S8 + seems to have a bluish tint, colder than the S7 Edge.

Both have excellent displays, but only the S8 + has HDR support, which is remarkable when we put a video or series capable of taking advantage of these capabilities of the team. I have several samples in HDR and, after seeing them side by side with the S7 Edge, the difference is noticeable. For the rest of the typical content – games, web pages, conventional videos, the difference between both panels is minimal.

Where we do have a significant difference is in the size of the screen. The 6.2 screen may sound much bigger than the 5.5, but in reality, the difference between the two is not so much. This is because the screen of the S8 + is higher than other phones, to use the 18.5: 9 format.. This gives us the possibility to fit more vertical content, which is what we consume the most on mobile devices (messages, websites, texts, etc.). Actually, the 6.2 screen of the S8 + is closer in total area to that of a 5.7 phone. In fact, it is almost as wide as the S7 Edge.

On screen, the S8 + not only outperforms the S7 Edge, but any other rival on Android or iOS. It is by far the best display on a mobile phone currently available on the market.

Battery and Recharge

Samsung has preferred not to risk much on this issue and instead of placing a large capacity battery – as it happens, for example, in the Mate 9 with its 4,000 mAh battery – it has put one of more discreet size: 3,500 mAh. For a phone with such a large screen (roughly the area of ​​a 5.7 screen), the battery life it gives us is pretty good, higher than that of the S7 Edge.

Samsung has managed to optimize battery consumption, which translates into an average of 5 hours of Screen on Time in common use. It was only on days of heavy use (using the S8 + as a video camera alongside my DJI Osmo Mobile, combined with several hours of browsing, YouTube and Hearthstone, for example) that I had to charge it in the middle of the afternoon (4 – 5 PM). With more traditional use, the phone quietly lasted until 9 or 10 at night. It is not exceptional, as we have seen with mid-range phones such as the Moto Z Play or the Huawei Nova Plus, but it is quite good. In the high-end, however, the Mate 9 is still superior.

But if we compare these two phones, don't be fooled by the numbers: The S8 + offers slightly higher endurance or durability than the S7 Edge, but this may be because the S7 Edge's battery is already a year old, so I'd say it's the same level of autonomy.


The S8 + takes great photos. Honestly, I didn't notice any significant improvement with the S7 Edge. Now, make no mistake: the S8 + (and S7 Edge) is still one of the best cameras on the market in Auto Mode. The combination of the camera app with Samsung post-processing, together with the Sony sensor, achieve great results, especially at night, where most smartphones suffer.

Unfortunately, the competition has not stood still and, in my opinion, dual camera proposals such as the LG G6 and Huawei P10 offer a better photographic experience – as long as you want to take the time and effort to work with the different manual modes. options we have. For photography fans, other phones offer greater versatility. If you are only interested in point and shoot and get a good photo, the S8 + (and, by extension, the S7 Edge), they are still the kings on this topic, on Android.

There is no doubt that Samsung is working on a dual camera system – its patents give it away – but perhaps due to lack of time, or looking for some extra differential for its war horse in the second half of the year, this evolution in camera did not happen. he found the S8.

If the camera is what they value most in a smartphone, and they have an S7 Edge, the upgrade is not worth it, there are no significant changes in the rear camera.


A brief device just to mention that both phones are now in Nougat and offer very similar features.

Some extras that are worthwhile in the S8 + is the possibility of using some Edge functions that allow us to record part of the screen, convert it to GIF, and more.

A big point against the S8 and S8 +, however, is Bixby, Samsung's attempt to make a copy of Google Assistant or Siri. The big problem is that Samsung has dedicated a button to it, and placed it just below the volume button. This translates

Galaxy S8 vs S7: Is it worth updating?

If they come from an S6, an S6 Edge, a Note 5, yes, the difference is brutal. If they come from an S7 Edge or S7, they may not notice so many changes, but the best screen, the spectacular design are, in my opinion, enough excuse.

Now, If you do not have any of these models, and you have to choose one, I will undoubtedly go for the S8 and S8 +. Why Well, because they are the ones that will have more support from Samsung; When Android O appears, they will surely be among the first phones to be updated.

The S8 and S8 + are, without a doubt, some of the phone candidates of the year, and the finest exponents that Android has to offer. However, it is not the only operating system on the market, here you can know the Advantages and Disadvantages of Android and iOS
