I am here at the Mobile World Congress, where The party has just started with one of the most anticipated releases of the year. This time, anticipating the whole world, Samsung has announced the successor to the popular S8, the Galaxy S9 and S9 +, both with notable technological advancements!
Outwardly the phones have not changed much and honestly there was not much to change. The industrial design of the S8 and S8 + remains among the best in the industry, with a vibrant AMOLED display – the best on the market – as the main star. However, Samsung has made improvements to major points that are an excellent excuse for anyone to upgrade.
So what is new about this Samsung Galaxy S9 and S9 +?
A much superior camera
This year, the S9 and S9 + offer more differences from each other. Formerly distinguished only by screen size, physical size and battery, now the S9 + offers an extra: a dual camera on the back. Both have a 12-megapixel dual-aperture (f / 1.5 and f / 2.4) camera, but only the S9 + has a second camera, with a 56mm focal range (a kind of 2X optical zoom), with an aperture of f /2.4. It is the same combination of lenses that the Galaxy Note 8 gave us.
What is a variable aperture?
Until now, all manufacturers have competed to give us the brightest aperture in a camera, and Now Samsung brings us the phone with the brightest aperture, f / 1.5. To have Greater openness helps us two things:
- Night photos will come out with less noise and better quality, because the sensor manages to capture more light from the scene. Imagine a room without light sources, where we have a window to the outside. A larger aperture equates to a larger window, which lets in more light.
- The bokeh or unfocused background is more accentuated. With a larger aperture, our focal length, the things that are in focus, is less. When we have a smaller aperture (f / 8, for example), more things are in focus. Therefore, with an f / 1.5 we will get a bokeh or defocused background more easily.
But having such a bright aperture brings a problem: loss of detail by day, or in very bright scenes. If our lens is f / 1.5, we will be able to capture excellent night images, but as soon as we want to capture photos of the beach, for example, we will notice that it is too bright, and that everything will be overexposed (white, or very shiny).
Traditional cameras can correct this because cameras they can close the opening like this:
Using the previous analogue, it is like replacing our window with a smaller one, in order to prevent so much light from entering.
Good, the cameras on our smartphones have not been able to vary the aperture, until today, with the launch of the Galaxy S9. This will allow the S9 to excel in both night and day photos, by being able to vary the aperture from f / 1.5 for dark situations, to a more reasonable f / 2.4 when we're on the day..
It is an important technological advance, as it gives us the possibility to continue exploring much brighter apertures for these small sensors, without compromising the ability of these cameras to take daytime photos.
Super slow motion
Other aspect extremely interesting, is the ability to record video in Super Slow Motion, up to a maximum of 960 frames per second in 720p! I am a super fan of Slow Motion. Slow Motion not only works for action scenes, of course, but when we want to make secondary shots (B-Roll), it adds an additional level of drama to any scene. Traffic, lights, simple actions like walking, are accentuated by slow motion, and it is an excellent possibility to have it included in the camera.
F / 1.7 front camera with autofocus
To round off the subject of cameras, in the S9 and S9 + we have an AutoFocus camera with an f / 1.7 aperture, which should help a lot with selfies
Much improved sound
The Note 8 Plus that I've been using frequently has become one of the optimal ways to enjoy Netflix and YouTube content, because Samsung makes the best AMOLED screens on the market, and many series and movies work in HDR on Samsung devices. . The only thing missing? A good sound, as so far, we've had a single speaker at the bottom.
This has finally been remedied with the Galaxy S9 and S9 +, where Samsung has included a pair of stereo speakers at each end of the device.tuned by AKG audio specialists. Not only do we have stereo speakers, but thanks to this tuning, we can achieve a surround effect of the audio.
It should be noted that the sound we get is much, much more powerful than the S8 and S8 +. It closely resembles more powerful computers, such as the HTC U11 or Mate 10 Pro.
Exynos 9810, RAM, and Battery
The new Exynos 9810 is the second processor with the 10-nanometer manufacturing process, which has given Samsung time to refine its processor and give us more speed. We have 4 low consumption cores at 1.9 Ghz, with 4 performance or performance cores at 2.9 Ghz.
Another change between the S9 and S9 +. it has to do with the amount of available RAM. In the S9 we have 4 GBs – which, honestly, is more than enough for Android Oreo – while in the S9 + we have the same amount that the Note 8 has, 6 GBs of RAM. These additional 2 GBs of RAM will ensure that we can keep more apps in memory. In addition, both teams come with 64 GBs of internal storage that we can expand with microSD cards.. 64 GBs of storage is still a fairly acceptable figure when we combine it with a microSD where we can host our videos and photos.
As for the battery, the S9 has a 3,000 mAh battery while the S9 + comes with 3,500 mAh. This, I think, is the only point that Samsung could have improved a little more; I would have liked to see a battery of at least 4,000 mAh in the large model, and 3,500 mAh in the small model. However, we do have fast charging and fast wireless charging to give the phones more battery power.
The S9 and S9 + come with Samsung Experience 9.0 and Android Oreo 8.0. The phones maintain, of course, the IP68 certification, allowing us to immerse them in water for 30 minutes up to 1.5 meters.
