This part of the review Samsung Galaxy S8 + is dedicated to screen and battery tests. How successful is the Infinity Display in terms of color reproduction, brightness, readability in the sun? How long will the Samsung Galaxy S8 + last on a single charge under different modes of use?
Samsung Galaxy S8 +: screen
The Galaxy S8 + has a beautiful, resonant and memorable name Infinity Display. An endless display extends from edge to edge. The side bezels are missing, and the top and bottom are so small that they even had to remove the Samsung logo, which so annoyed many fans of the brand.
Passport data Galaxy screen S8 + you probably know, but according to the laws of the genre they need to be voiced. Diagonal 6.2 inches at QHD + resolution gives pixel density in the area 530 ppi... The panel is, of course, Super Amoled, which guarantees maximum black depth and excellent contrast.
We'll get to the tests later, for now let's say a few words about the resolution and aspect ratio of the Galaxy S8 + screen. The default resolution is not QHD + but 2220 x 1080 pixels, that is, FHD +. This permission is used for Android and all applications. You can manually set a lower resolution 1480 x 720... Whether it is necessary to do this is another question ... in battery tests, lowering the resolution did not extend the battery's life.
Galaxy S8 + aspect ratio (18.5: 9) is a topic for a separate discussion, therefore, within the framework of this article, we will voice the main points. It will not be difficult to adapt applications and games to the new resolution, there will be no problems here. But media content is more difficult to redo, as are the photos taken by the Galaxy S8 + camera. When watching videos and photos, black bars cannot be avoided.
Galaxy S8 + screen does not support Dolby Vision, but supports technology HDR10, which guarantees maximum saturation, realism and vividness of the image. According to display experts DisplayMate, Infinity Display can reproduce more colors (142%) than the standard sRGB color space can accommodate. The S8's screen received the highest A + rating from DisplayMate and is ideal for viewing HDR content.
The problem is that HDR content is scarce, and what is available is only available in UHD packages (on Netflix, for example) and requires 4K screen resolution, which the Galaxy S8 + cannot boast. However, the lack of HDR content is unlikely to become a weighty argument against the Korean flagship, so we will not focus on this.
At the sub-pixel level, the Galaxy S8 + uses a Diamond Pixel layout. Its peculiarity is that the elements responsible for displaying blue, red and green (sRGB) colors differ in size and shape. The largest sub-pixel is blue, followed by red, and green is the smallest. The shape is also different: the blue and red sub-pixels are in the shape of a diamond, the green in the shape of an oval.
This layout allows you to achieve maximum image brightness and avoid artifacts when drawing small details, in particular, straight and diagonal lines. In terms of color reproduction, the Galaxy S8 + has an excellent display: an average color accuracy ratio of 3, a maximum of 5.6. DeltaE is less than that of direct competitors; despite the saturation of colors traditional for the Amoled matrix, it conveys colors better than the LCD panels installed in almost all flagships of spring 2017.
Samsung Galaxy S8 +: display tests
They said about good color rendition, and the brightness of the image is also in full order. When testing the Galaxy S8 + screen in DisplayMate labs, it was able to achieve a brightness of 1020 nits. GSMArena experts were able to squeeze a fantastic 870 nits out of the S8 + display. True, space brightness indicators are achieved only in specific conditions, in particular, when only a small white rectangle is highlighted on a black screen.
In real life, the screen brightness of the Galaxy S8 + will be lower: 442 nits in standard mode and 647 nits at automatic settings to the maximum. Since the Amoled matrix allows you to get, in fact, absolutely black, the contrast of the display is at an infinitely high level, which once again justifies its name - Infinity Display.

The readability of the Galaxy S8 + display in the sun, as predicted, is beyond praise. The best on the market at this moment! In terms of readability in the sun, the S8 + outstripped its predecessors and confidently came out on top in the current table of ranks. Next came the S6 + and S7 edge. Samsung's closest competitor, the OnePlus 3T, is 400 points behind, although it also has a Samsung Amoled display.
Sun Contrast Ratio
At the end of the conversation about the S8 + display (which, in fact, can be continued indefinitely), let's say that minimum brightness was 3.30 nits... In the evening and at night, the S8 + screen will not blind you, working with the phone is quite comfortable.
The Galaxy S8 + has four operating modes. Cinema Mode is tailored for films, Photo - for viewing and working with photos. There are also Basic and Adaptive modes. For daily work with the phone, it is better to choose the latter. In adaptive Galaxy mode The S8 + analyzes what is shown on the display and improves the picture based on it.
Samsung Galaxy S8 +: battery, battery life
Today it is customary to criticize phones for low battery life, and you can't say that criticism is not the case. Many smartphones, even astronomically expensive ones, barely make it into the evening. When the screen is active, the battery is discharged in 7-9 hours. It is generally better to keep silent about games - it's good if the battery lasts for 3-4 hours. So, the Galaxy S8 + in this component has bypassed the competitors - over time autonomous work it has a complete order, at least for a phone with a diagonal of 6.2 inches.
Tests Galaxy battery S8 + showed that with the screen on 3500 mAh lasts 12-16 hours... When working on the Internet, the operating time is less (12 hours), which is explained by the additional load on the modem. When watching a video, the figure, frankly speaking, is impressive - not every smart with a diagonal of 5.0-5.2 inches can work for 16 hours. You can't expect such a high autonomy from large phones ...
| Galaxy S8 + (Exynos 8895) | |
|---|---|
| Battery capacity | 3500 mAh |
| Fast charging | Quick Charge 2.0 |
| Wireless charger | Supported |
| Autonomy rating | 88 hours |
| Autonomy with AOD | 58 hours |
| Calls | 23:43 |
| the Internet | 12:16 |
| Video | 16:03 |
Overall rating of autonomy at Always-On-Display disabled was 88 hours. This means that if you watch a video for 1 hour, chat in 3G networks for 1 hour and surf the Internet for another 1 hour, the Galaxy S8 + battery will last more than three days. Of course, in real life, the battery life will be shorter, as dozens of applications running in the background also consume battery.
When the Always-On-Display function is enabled, the autonomy rating is reduced to 55 hours, which, in principle, is normal. According to the developers, AOD consumes about 1% of the battery per hour, so reducing the battery life of the Galaxy S8 + on a single charge is an inevitable price to pay for the convenience that this option provides.
By good tradition, the Samsung Galaxy S8 + supports wireless charging... The Exynos 8895 version of the smartphone supports QC 2.0 and adaptive fast charging(Adaptive Fast Charging). The Galaxy can be charged from zero to 100% in an hour and a half. Considering the battery capacity of the S8 +, it's not bad overall.
This concludes this part of the large Galaxy review S8 +. If you find inaccuracies or errors in the material, please write in the comments, we will correct it.
And the S8 Plus has a lot of interesting features. One of them is the non-standard aspect ratio of the display. Many might think that the LG G6 looks no less interesting in this respect, but it is not. The guys from Samsung went further, because if in the case of the G6 we are talking about the ratio of 18: 9, the Samsung Galaxy S8 received an aspect ratio of the display of 18.5: 9, in other words, the device is even longer than its competitor.
This is done so that users can comfortably hold a device with a large diagonal with one hand. Given the almost complete absence of a framework, such a step is quite justified and the result will be noticeable. The display in the S8 occupies 84.26% of the front panel.
Our colleagues from phonearena performed some calculations and came to the following conclusion. If the Galaxy S8 had a standard display aspect ratio (16: 9), the device would be 5.57 inches diagonal. In other words, the S8 would be identical in this respect to the Galaxy S7 edge. The display diagonal of the Galaxy S8 Plus would have been 5.95 inches at the usual ratio.
Videos with a 16: 9 aspect ratio running on the Galaxy S8 will look like this:
Due to AMOLED technology, the black frames on the sides will not be visible and when watching a movie they will simply merge with the frames of the device. That said, these black bezels make up 13.5% of the entire display area. In addition, the problem can be solved by scaling the picture. However, we note that almost all new films have a ratio of 18: 9, not 16: 9.
This is how the Galaxy S8 would look at 5.5-inches - marginally wider and significantly shorter. However, let's face it, the regular 5.77-inch S8 looks much more interesting and modern. What do our readers think of the non-standard aspect ratio? What, in your opinion, are the advantages and disadvantages of this ratio?
A photo has appeared showing the Galaxy S8 has received a screen resolution setting. It is presented by a slider, on which resolutions are located from HD + to WQHD +, Full HD + took a position in the middle. It is this average value that is set by default. Apparently, this feature was taken over from the Galaxy S7, which got it after upgrading to Nougat.
With the official release of Android 7.0 Nougat for the Galaxy S7 and S7 Edge, Samsung fans have received a great gift in the form of over 20 new features and redesigned visuals. However, some users have encountered a problem - the display resolution of their devices dropped after the update. However, this was not a mistake to worry about, but new function, which allows you to independently change the screen resolution. We don't always need the highest resolution, and a low one has a positive effect on battery life.
As you can see from the image, the Samsung Galaxy S8 can do the same, but the new display resolutions are more interesting. The actual screen resolution - WQHD + or the unorthodox 2960 x 1440 pixels - suggests that rumors of an 18.5: 9 aspect ratio may eventually turn out to be true. This new ratio, called Univisium, is similar to what LG has proposed in the G6. It makes smartphones taller but narrower. The default FHD + screen resolution is actually 2220 x 1080 pixels, and the new HD + is 1480 x 720.

You can easily change the screen resolution up or down, whichever is important to you.
You can downgrade the resolution to the lowest HD + value to maximize your smartphone's battery life, or if you want smartphone panels that are especially useful for working with Gear VR, you can set the maximum resolution.
Which phones can I change the resolution on?
This is a relatively new feature for Samsung devices It came with the Galaxy S8 and Galaxy S8 Plus. If you own a Samsung or, you will find the same feature available when you upgrade to Android 7.0 Nougat.
Despite the exit Android updates 7, Galaxy S6, Galaxy S6 Edge, and Galaxy S6 Edge Plus do not offer this feature.

The Samsung Galaxy S8 will be unveiled in a week, and there are more and more leaks about the upcoming flagships. This time, a photo of a smartphone screen was leaked, showing a menu section dedicated to adjusting the resolution. As we can see, the maximum display resolution will be 2960 × 1440 pixels, or WQHD +. As in the modern generation of flagships, if necessary, users will be able to reduce it to 2220 × 1080 pixels (FHD +) and 1480 × 720 pixels (HD +).
In addition, photos of the batteries that will be used in the devices have been published. Pictures have confirmed that the Galaxy S8 will have a 3,000mAh battery. The Galaxy S8 + variant will be equipped with a larger 3500 mAh battery, as the display of the device is larger.
