What are the differences between the Samsung Galaxy S8 and Samsung Galaxy S9? Which is better?

The new releases allow many users to pay attention, when buying a mobile phone, in the previous models, between one and three years ago, which have dropped considerably in price. This occurs, above all, in those brands that launch high-end devices and whose starting prices are too high.

A clear example of this would be Samsung, with its new Galaxys that we see year after year but do not stop rising in price. Therefore, you may be wondering right now, if you need to change your phone, what are the differences between the Samsung Galaxy S8 and Samsung Galaxy S9 .

Samsung Galaxy S8 phone’s main features

The Samsung Galaxy S8 is as nice as we all expected for its launch:

Samsung Galaxy S8

  • Aesthetically follows the line of others, with the subtle transformations that make them more and more stylized every year. 5.8 inches, three colors to choose from, only 155 grams, aluminum, glass and a beautiful curved finish perfectly describe the model.
  • The firm is never surprising in terms of quantity of MPx, although we already know that it is not always better, but that the quality of the sensors is so important, or more. Thus, the model has 12 and 8 MPx for its cameras .
  • The first one allows us to record video in Ultra HD in a way already decent, taking an important leap in this regard.
  • The battery is still a point where the firm limps, including 3000 mAh , although, yes, we enjoy the option of wireless charging .
  • Inside we find a Exynos 8895 and a GPU Mali G72 .

  • Samsung makes an interesting change by placing the fingerprint reader under the screen , thus gaining aesthetics.
  • Another aspect of the design that changes, and expected, they are the colors in which the model can be chosen . This point is interesting because the user enjoys the possibilities a lot but we don’t really talk about an effort by the firm, which keeps the design of the phone intact, turning its efforts towards other points.
  • Of course, regardless of that we compare this with the previous one or with any other mobile launched a year before, we find that both processor and graphics are updated but without major changes beyond those of performance of the improved versions.
  • We enjoy a camera with better focus, counting the rear with variable focal aperture of f / 1.5 to f / 2.4 .
  • The firm worked hard to present the Slow Motion of the model.
  • Sound is one of the highlights of this phone, since a second speaker is integrated and compatible with Dolby Atmos .
  • The lace is put on the facial recognition ng>, an addition to the many that we have been enjoying with the previous models.

Although you can already get an idea of ​​the novelties and distinctive elements that both models include, of course, the interesting thing is to be able to see, point to point, what they have similar and how they differ in order to make a clear comparison.


At this point we see that the biggest difference lies in changing colors . While the old model appears in orchid gray, silver and black, the most modern is in Lilac Purple, Titamium Gray, Coral Blue and Midnight Black.

In size and weight, although they are not identical, we see that their characteristics turn out to be invaluable when considering one and the other, since we speak of 155 and 163 grams and 148.8 x 68.1 x 8 mm and 147.7 x 68.7 x 8.5 mm respectively for 8 and 9. Already distinctive of this line of smartphones, glass, aluminum and curved shape are maintained .

Regarding this we see that there is nothing crazy; Similarities and subtle changes. Yes, we find the pleasant novelty in the S9 of including the fingerprint reader under the screen , which makes it visually more attractive to better maintain its lines.


Identical Super AMOLED Dual Edge screens of 2960 x 1440 pixels with Gorilla Glass 5 and reproduction of 16 million colors.

Processing and storage of information

Let’s go first with what is maintained, which is the capacity of the RAM, 4 GB and LPDD4X type in both cases .

The internal memory of both is 64 GB , although the S8 offers us, real, 2.3 GB while the S9 only allows us to enjoy 50.3 GB. It does change the extension through MicroSD, which is conventional, up to 256 GB in the case of the first, while in the second we are allowed to reach 400 GB .

Improve the processor , maintaining the same but in its corresponding evolution, and we pass from an Exynos 8895 to the Exynos 9810 , which also increases the clock frequency to 2.9 . These are supported by an ARM Cortex A53 and A55 respectively.

There is also a logical and small jump in terms of graphics, which become about ARM Mali-G72 MP18 from ARM Mali-G71 MP20 . Also the operating system is updated, moving from Android 7.0 to Android 8.0 although, at this point, both phones can be updated to new versions without problem.


We see that, despite having bet that the Samsung Galaxy S9 would be launched with a dual camera, it was no more than in its Plus version. In this way, we maintain 12 MPx in both models, although it does improve the focal aperture , which in S8 is f / 1.7 and in S9 it becomes variable, going from f / 1.5 af / 2.4.

The sensor that the signature includes is the one immediately following in S9 with respect to S8, being S5K2L3 and S5K2L2 respectively, although this is something that is invaluable. In the case of the selfie camera, we have 8 MPx with the same focal aperture f / 1.7 .

Very interesting is the improvement in REC video, which goes from 4K UHD at 30 fps to UHD 4K at 60 fps . In addition , the most current model records in Slow Motion at 960 fps in HD and at 240 fps if we want to enjoy content in Full HD, aspect that the firm made an effort to show when it made the announcement and later launch of the smartphone.


Nothing new under the sun . 3.5 mm jack with stereo sound and USB-C On the Go with massive storage, location software, radio, navigation and other identical software, as well as version 5.0 of bluetooth and dual WiFi. Surely indifferent to most is the inclusion of the B32 type 4G band for coverage.


The battery of the two phones is identical in capacity, being 3000 mAh , and type, Li-Ion. However, the brand ensures that the one included in the S9 gives us more hours of talk time and audio playback . In any case, no part is removable and has fast and wireless charging.

​​ Sound

To the 11 audio playback formats that the S8 has is added, for S9, the APE ; another point that almost nobody considers but that we have to comment, of course.

Stereo sound, only available with headphones, is now also enjoyed, with the S9, by the speakers when a second is included in the upper area of the phone, next to the headset. In addition, it is compatible with Dolby Atmos , which makes the sound, if it is of sufficient quality, more enveloping.

Other details

We see sensors such as accelerometer, gyroscope, proximity, light, geomagnetic, light … Nothing changes in this case. The IP68 certificate is also maintained.

Yes we find new features and features such as ANT +, Computer Sync, Tethering or OTA Sync in the S9 model . We also see a biometrics that improves with the inclusion of facial recognition ; that of iris remains.
