Smartphone Galaxy S8 began to discharge quickly? There is a solution from Samsung. Three months with the Samsung Galaxy S8: Still the best? Samsung galaxy s8 battery charge

There is no choice, despite the use of two different SoCs. Samsung has released a smartphone on both Qualcomm Snapdragon 835 and its own Exynos 8895, but only the latter option can be bought in Russia and Europe. The chip was introduced in mid-February, but not all the details have been known so far.

Among the innovations are the Exynos M2 CPU cores, which Samsung developed independently. As the Korean company points out, compared to the M1, efficiency and performance have increased (by 27%), but the modes of operation and changes in clock frequencies are not disclosed. Therefore, information has to be obtained experimentally.

Exynos 8895 gives you more performance than you need

The four Exynos M2 cores in the Galaxy S8 are rated at 2.31GHz, while the four Cortex A53 cores can only clock up to 1.69GHz. So the speed of the faster cores is below the 2.49 GHz announced for the Exynos 8895. We experienced a similar situation in the case of the Exynos 8890, but the clock speed of two of the four M1 cores could briefly increase above the set bar. But now there is no Boost mode, so a productive cluster can no longer run at two different frequencies. At least that's what the tests say, since a separate load on the fifth to eighth cores always led to the same frequency. The situation is different with the second cluster. The frequency does not exceed the specified maximum, but the cluster can operate at two frequencies at the same time. That is, cores 1 and 2 can operate at a different frequency than cores 3 and 4.

What is hidden under the Exynos M2 is not exactly known. Judging by the performance, we have a modification of the ARM Cortex-A73 cores that worked in the same Huawei Kirin 960. But Samsung's optimizations justify themselves: depending on the test, Exynos M2 shows a performance increase of up to 8%. We achieved 2,000 points in Geekbench 4.0 and 4.1 single-threaded tests, a record high in our test lab. The performance increase compared to Exynos 8890 and Galaxy S7 was about 5%. According to the overall CPU rating, the situation looks different. We got excellent scores of 6.300 and 6.600 points, but the performance of the Kirin 960 is comparable. The advantage of the faster Exynos M2 cores over the Cortex-A73 in Samsung is offset by the lower frequency of the Cortex-A53 cores. At Huawei, they not only work more than 100 MHz faster, but we also feel that they can withstand maximum frequencies longer.

Left: The Cortex-A53 cores in the Exynos 8895 SoC can run at different frequencies in a cluster. Right: M1 followed by M2. In the case of the Exynos 8895, Samsung used its own Exynos M2 cores, but they all run at the same frequency.

It is interesting to compare with the Kirin 960 and the GPU. Samsung also chose the ARM Mali-G71 graphics core, but unlike Huawei, 20 clusters (MP20) are used here; the Kirin 960 only had eight clusters available. SoC Exynos 8895 supports Vulkan, Open CL 2.0 and other modern interfaces. Interestingly, Samsung has set the maximum clock speed at a very low level - only 546 MHz. For comparison, the Kirin 960 GPU can run at up to 1.037 MHz. In this case, it was enough for the smartphone to take first place in the GFXBench tests (Manhattan Offscreen and T-Rex Offscreen). However, he did not stay there long. With the results of 64 and 120 fps, the Galaxy S8 smartphone on Exynos 8895 came out on top, beating the previous leader by 30 and 26%. Here, a larger number of clusters at a lower frequency justify themselves. However, if you thought that in this way Samsung will avoid the throttling observed in the same Kirin 960, then it is completely in vain. After a short load, performance decreased by about 20%. Of course, temperature continues to play an important role here. At the back of the smartphone, we received heating up to 41 ° C. Unfortunately, it was not possible to read the SoC temperature due to the lack of compatible utilities. However, the drop in performance in practice is not felt. Even after throttling, the Exynos 8895 is slightly faster than the Kirin 960 under optimal conditions.

Exynos 8895 provides full performance for short periods of time, the back of the Samsung Galaxy S8 only reached 41°C

In general, Samsung's 10nm LPE process justifies itself. In the AnTuTu 6 test, the smartphone scored 172,000 points, but the reason lies mainly in the GPU. The same goes for 3DMark in a Slingshot run: 3,900 points is impressive. Except that the PCMark scores of the Galaxy S8 are not as high as we would like. The smartphone is 30% faster than its predecessor, but 6.100 points was only enough to enter the top ten models on SoC Snapdragon and Kirin.

But back to practical observations. In tests, none of the applications were able to load the Galaxy S8 to the limit. The new smartphone provides more than enough performance for all applications, and two to three years ahead. Of course, if the memory does not become a "bottleneck". The smartphone is equipped with 4 GB LPDDR4 memory.

Too bad it's not supported. So if the user decides to install a smartphone in VR glasses, then either ordinary cardboard glasses or the Samsung Gear VR branded model will do.

Galaxy S8 has everything you need

But Exynos 8895 shows convincing results not only in terms of CPU and GPU performance. Samsung has beefed up data transfer technologies compared to the Galaxy S7. The built-in LTE modem supports Cat 16 and 13, which is well ahead of the networks of mobile operators in Russia and Europe. The Galaxy S8 can download data at gigabits per second (Cat 16) and upload at 150 Mbps (Cat 13). Therefore, for the coming years, the capabilities of a smartphone to work in LTE networks will be more than enough. We had no complaints about the quality of the connection. During the tests of the Galaxy S8, we did not encounter any disconnections or frequent network switching.

Of course, voice quality is just as important. Thanks to well-functioning microphones (in the amount of two pieces), the smartphone reliably suppresses background noise. In tests, our interlocutor heard his voice clearly, the earpiece provides sufficient volume and closes the most important frequencies. For hands-free calling or music playback, a second speaker is provided, it is located on the Galaxy S8 from the bottom of the case. It also gives a fairly high volume level, although you should not expect mids and low frequencies. Stereo functions, unlike the same or Huawei P10 Plus, are not supported here.

In Russia, Samsung sells a Dual SIM version, there is also a high-speed LTE modem

802.11ac is supported for WLAN operation, thanks to MU-MIMO (VHT80 and 1024QAM) support, not only high speed is guaranteed, but also stable operation even with many devices on the same network. The Bluetooth standard works at a slower speed, but it is no less important. For the first time we get a smartphone with Bluetooth 5 support, compared to 4.2, the transfer rate has increased to 2 Mbps. The Bluetooth SIG promises further efficiency gains. However, the standard is backward compatible, so there will be no problems connecting old accessories.

Not without NFC. The Galaxy S8 also supports the ANT+ protocol, which is very popular with heart rate monitors and other sports accessories. There is also support for MST. This feature can simulate the magnetic stripe of bank and other cards, which Samsung uses for its Samsung Pay payment service. Satellite navigation capabilities have expanded, now the smartphone can receive signals from Galileo satellites in addition to GPS, Beidou and GLONASS.

The Samsung Galaxy S8 has an audio jack for connecting a headset, and a USB Type C jack for charging and data transfer.

Samsung has not spared two physical interfaces: a 3.5mm headphone jack and a USB Type C port that is compatible with the DisplayPort standard. The transfer speed is USB 3.1 Gen 1, which is a pleasant surprise. But the built-in memory of the Galaxy S8 is not the fastest. 64 GB of flash memory is connected via UFS 2.1 interface, according to the Androbench test, the read speed is 411 MB / s, the write speed is 68 MB / s. The PCMark test gives better results: a read speed of 628 MB / s and a write of 126 MB / s. The results are good, but some competitors give faster speeds. However, the speed of working with a memory card is even lower. The smartphone can install a microSD memory card up to 256 GB, but only instead of the second SIM-card.

A headset with the AKG logo is included with the smartphone. This brand is now owned by Samsung, which has a positive impact on the quality of the bundled headphones. Compared to most bundled headsets, here we get a more harmonious and powerful sound.

Fingerprint scanner and iris help little

We did not receive significant changes in sensors. There are accelerometer and gyroscope, barometer, proximity and light sensor. Below the LED flash is once again a heart rate sensor that can also measure blood oxygen saturation.

Additional protection is provided by two sensors: a fingerprint and an iris. The first during the transformation was moved from the front side of the smartphone to the back, now it is located next to the camera. The latter is installed above the display. In our tests, both sensors failed to convince, so most users will probably prefer to unlock the Galaxy S8 via PIN or pattern.

The fingerprint scanner (to the right of the camera) on the Samsung Galaxy S8 is difficult to reach, recognition accuracy leaves much to be desired

The fingerprint scanner is poorly located, it is very inconvenient to reach it. Moreover, it works with low accuracy. The same goes for the iris scanner. If you wear glasses, you will need to remove them for the initial iris scan, but you can unlock your smartphone while wearing glasses. Unfortunately, even without glasses, recognition accuracy also leaves much to be desired.

Facial recognition is hardly an alternative. This technology has already been deceived after the introduction of two smartphones through photography.

Galaxy S8 lasts longer than its predecessors

Let's move on to the battery. The capacity of the built-in battery was considered insufficient by many after the announcement of the Galaxy S8. Of course, the 3,000 mAh capacity is comparable to the direct predecessor of the Galaxy S7. But when you consider the size of the display and body, the Galaxy S8 still follows the Galaxy S7 edge more. In this case, the capacity decreased by 17%.

But capacity is only one side of the coin. Still, do not forget about the hardware and software. There have been changes here. Let's start with the Android 7 operating system, which supports the improved Doze feature and various optimizations. In addition, the SoC is produced according to a modern process technology, which allows us to hope for greater energy efficiency. On the other hand, increased resolution leads to higher power consumption.

The good news: The Galaxy S8 didn't outperform the Galaxy S7 or Galaxy S7 edge in three battery life tests.

The battery life of the Samsung Galaxy S8 exceeds that of its predecessor, despite the higher pixel count and larger display diagonal.

In our video looping test, the smartphone lasted 14.5 hours, so it could well keep the user entertained over a long flight. Compared to the Galaxy S7 and Galaxy S7 edge, the increase was about 27 and 7%. In the PCMark test, the Galaxy S8 showed a decent nine hours. Here we got an increase of 21 and 7%.

But in practice, the increase is felt weaker. In our usual test, when we made several short phone calls every day, browsed websites and emails via WLAN and LTE, used instant messengers and social networks, the smartphone lasted 53 hours. Then we turned on the Always-On function, but it did not significantly affect battery life. The difference was one to two hours.

If you want to get more battery life, then in the system settings it makes sense to select alternative resolutions and performance levels. Special power saving modes are also available. However, they will not help much if the user will run games. In such scenarios, you should not leave the outlet for a long time. If you run demanding applications (the same games), then the battery life drops to five hours.

Fortunately, wireless charging (Qi and PMA) is supported, as well as high-speed wired charging. The included power supply provides up to 15W of power, and it takes less than 130 minutes to fully charge your smartphone.

We have already drawn parallels with old flagship smartphones Samsung compared to autonomy Galaxy S8 and his successor Galaxy S9 In the material: "The battery life of the Samsung Galaxy S9 is not impressive". Both devices have a battery with a capacity of 3000 mAh, but due to different technologies and approaches to energy saving, their capabilities diverged against the newer model.

Manufacturer Specifications:

• reduced communication time in Samsung Galaxy S9 - 2 hours less compared to Galaxy S8,
• but extended by 13 hours music listening mode;
• the rest of the indicators should remain without changes;
• a similar picture for the top ones Galaxy S9 Plus vs S8 Plus.

Now it's time for expert opinions. Notable edition Android Authority conducted its own research, which uses various test modes - HD resolution and 4K in mixed load, Internet surfing via Wi-Fi and video playback.

Comparison of the autonomy of Samsung Galaxy S8 and Galaxy S9 in Android Authority tests

Working time measurements Galaxy S8, S8 Plus, S9 and S9 Plus were carried out in laboratory conditions with three main and equivalent loads. Look what happened in the end - the old S8 line clearly shows the best result.

If we discard the processor difference Samsung Galaxy S8 and S9, then these are generally very similar phones. But of them, the “oldies” work better offline. Galaxy S8 and S8 Plus, Unlike Galaxy S9 and S9 Plus.

Do you have one of these smartphones, and it holds a charge clearly worse than indicated in these statistics? Try this official recommendation to improve autonomy. But even when no settings help to improve autonomy (and even those specially recommended for the Galaxy S9), then try replacing the battery with a new one. For this:

Where to begin

Sooner or later, all owners of various electronic devices, mainly smartphones or tablets, are faced with the problem of quickly discharging the battery of their gadget. Some users immediately turn to service centers or stores, believing that the malfunction lies in some components, such as a battery. Others try to solve the problem by installing different firmware or trying to modify the installed software. Still others immediately begin to scold the manufacturer and change the device with the hope that this will not happen again. In this article, we propose to understand the issue and understand how to do the right thing if your smartphone or tablet is quickly discharged. Let's start with the main thing - before you panic and take any action, you need to ask yourself three questions:

1 How long should my device last? A day, two, maybe a week? What kind of work time do I expect from him?

2 How often do I use it? Every five minutes or once a day? What if I don't turn it off? Or vice versa, do not use?

3 What is the use case for it? Do I play games or listen to music? Or maybe I'm always on social media? What exactly do I use the most?

The answers to these simple questions will help us understand the situation and understand whether something really happened to our smartphone or tablet or if it's something else.

How long should an Android smartphone or tablet last?

First you need to understand that the operating time of the device depends on a huge number of factors, and not just on the capacity of the battery (this, by the way, is one of the most common misconceptions).

Factors that affect battery consumption:

1 Use case. The more tasks you set the device, and the more difficult these tasks are, the faster the battery runs out. If you play games with excellent graphics, watch videos, use the Internet or GPS, like to set the brightness of the screen backlight to the maximum - do not expect your smartphone or tablet to show autonomy records, usually with this mode of use it sits down in 3-5 hours.

2 The quality and quantity of applications used. Today, the profession of a programmer is more popular than ever. Everyone wants to write their own application, get into the top downloads and earn fame as a famous developer. In pursuit of these achievements, programmers write thousands of programs and add them to the Play Store or similar stores. However, not all users understand that the quality of written applications can be different, because. not everyone who wrote these applications are really experts, or want to benefit other people. A large number of applications have poor quality performance or some hidden features that obviously will not benefit your device. For example, the application code may have a bunch of errors that force the device to work constantly and prevent it from "falling asleep", or have the functions of collecting and sending a large amount of statistical data to third-party servers. As a result, the processor will run at higher frequencies, consume battery power and constantly leak traffic with your personal data, which will lead to excessive heating and inefficient battery consumption. The number of installed applications also greatly affects the operating time, below we will explain why and invite you to verify this.

3 Technical condition of the device. All things invariably break down and become obsolete, the same fate befalls electronic devices. Over time, the capacity of the battery decreases, some components may fail. As a result, battery life starts to decrease. The built-in software (operating system) can also accumulate errors that lead to unstable operation of the device, its freezes, slowdowns, and rapid discharge.

4 External circumstances. For example, these include weather conditions (at low temperatures, usable battery capacity decreases dramatically; on a sunny day, the backlight should work at a higher brightness to improve readability) or the quality of third-party services and services (cellular reception level; Wi-Fi signal quality; correctness data synchronization with third-party servers).

5 Technical characteristics of the device. Engineering solutions may not always be successful. For example, if a smartphone has a large diagonal of the device, but a small battery capacity, then it will sit down in a matter of hours. But it is no coincidence that we put this factor in last place. In 99% of cases, all characteristics change proportionally (more screen or more powerful processor - more battery capacity), so the average operating time is always about the same. In addition, the technical characteristics include the characteristics of the components from which it is made. The fact is that not all of them have the same energy efficiency and performance. The newer the device, the more energy-efficient and efficient components it uses. This can be easily seen on the example of the Samsung Galaxy line of flagship smartphones and tablets. With each new generation, the screen resolution increases, the processor power increases, additional functions appear, but the battery capacity increases only by a small amount of mAh (by the way, why this happens, we will also explain below). However, the average running time does not decrease, but rather increases. In particular, this is due to the use of more energy efficient components (the size of the components is constantly decreasing, and with them the heating and power consumption).

Summing up: answer the question: "My phone runs out of battery for so many hours, is this normal?" very difficult, for this you need to collect a lot of information. To better navigate, we will indicate the operating time in the average mode (per day: a couple of hours of music, an hour of Internet surfing, a couple of hours in navigator mode, 40 minutes of calls, messengers or mail in moderation), this is about one to two days. But remember that everything is individual.

How to increase the battery life of your Android smartphone or tablet

Now let's see how we can eliminate the causes mentioned above, or at least try to reduce their impact.

1 If you honestly answered yourself the questions above and came to the conclusion that you do not let go of your smartphone or tablet, then we have bad news for you. It is impossible to increase the operating time with such use, since this requires a completely new type of battery, which mankind has not yet invented. But do not despair, there is always a backup option. In your case, this is the purchase of an external battery in which you can carry spare energy and recharge the main battery of the device. These batteries are available with different capacities, and you can easily choose the one that is right for you.

In addition, I immediately want to answer the frequent question why Samsung did not make a standard battery with a larger capacity. The fact is that not everyone plays games, watches videos or surfs the Internet. Most people use their smartphone moderately, do not load it with a lot of applications, and the standard battery is enough for them, for example, the author of the article uses a Galaxy S5 and it lasts for two days. If the standard battery had a larger capacity, firstly, the dimensions of already rather big devices would be much larger (you can’t put them in your pants pocket), and secondly, the price would also increase. That is why, with the help of additional accessories, we offer to increase the capacity exactly to the one you need.

2 Let's analyze what is important to know and understand when installing applications.

Every time you decide to install a new application, pay attention to permissions. Permissions are a list of what the app can do on your device once it's downloaded. The more permissions the application has, the more system resources it will use, and the more difficult it will be for the device to go into power saving mode (the so-called sleep mode), because the application can run in the background and will constantly wake it up, even if the screen of your gadget is turned off and nobody uses it. You can read more about permissions in our article.

Necessarily control the number of installed applications, because as we found out, each application has permissions, and if there are a lot of applications, then the permissions increase significantly. If there is an unnecessary application - delete it, do not leave it in reserve.

Try to choose those applications that are written by famous authors, downloaded many times and have a high rating. Of course, this is not a guarantee of stability, but it significantly reduces the risks. It is also useful to know that the functionality and stability of an application can not only improve, but also deteriorate with its updates. It often happens that no new applications were installed on the device, but suddenly it began to discharge quickly. The problem may lie in an unsuccessfully written update for some application.

To diagnose your device, you can use safe mode. It differs from the usual one in that only standard applications work in it, and all downloaded ones are disabled and have no effect on the system. If the problem disappears in safe mode, you can safely conclude that downloaded applications are to blame. However, at the moment there is no tool that allows you to find out exactly what kind of application it is, so they usually act like this: download the gadget in safe mode and check for a problem. If the problem is gone, then they load normally and start deleting those applications that were installed or updated last until they find the culprit. By the way, you can try to make such a test: boot your device in safe mode, note the time that it will work on a single charge, and compare it with the time it works in normal mode, we assure you, you will be surprised. You can read more about safe mode in our special article.

Also, the author of the article met user comments that pre-installed (embedded) applications are also to blame for the discharge. It is possible that there is some truth in this, but numerous experiments suggest that if there is an influence, then it is extremely insignificant. Moreover, the operating system is designed in such a way that the work of many applications depends on each other, and their thoughtless removal can only harm the device.

Nevertheless, it would be dishonest not to tell you about all the possibilities, so we share with you "secrets": some of the pre-installed applications can be disabled so that they will not affect the running system, i.e. they seem to fall asleep. How to do this, you can see in this article. You can turn them back on if needed.

3 Now consider which of the components can affect the operating time of the device. There are two possible reasons:

The battery - its service life is designed for a certain number of charge-discharge cycles. In use, usable capacity
starts to decrease until the battery can no longer hold a charge. That's why every one to three years the battery needs to be replaced(depending on the intensity of use). You can purchase original batteries at authorized Samsung service centers, branded stores, as well as from partner companies. The required model can be viewed on the old battery.

In addition, there are several myths that are firmly entrenched in the ranks of users, so I would like to separately note the following: the battery can be charged as you like, you do not need to discharge it to zero, keep it on charge for 15 hours, and do not be afraid to use your battery when charging. device, nothing will happen to it.

The motherboard is the most important component of your device. It can have completely different damage, as a result of which the device can quickly discharge. Professionals are taught to understand these damages, therefore, if you are convinced that the problem is not in the battery or in something else, we strongly recommend that you do not experiment on your own, but contact any of our service centers in our article.

Change your mobile operator if the coverage area does not suit you :)

What other advice can we give? There are few of them, but they are also very important:

Disable auto-sync of added accounts or configure it selectively.

Synchronization is the process of transferring various data from a smartphone to a server and vice versa. This data can be anything: new contacts, music, mail, photos, achievements in games, etc. When you are not using the device, it is in "sleep" mode, in which power consumption is greatly reduced. Synchronization works in the background, so you may not even notice how it "wakes up" the device. If this happens very often, then the device can be discharged much faster, even if you do not use it.

If you have tried all the recommendations in this article except contacting a service center, but nothing has helped, then you need to do a factory reset.

Resetting the settings is the return of the device to the factory settings, which erases all data, and with them the errors that accumulate in the device after active use. Factory reset is the best prevention against errors that occur over time in the operating system and applications. This is especially noticeable if you use a smartphone or tablet after a reset without immediately downloading a bunch of other applications to it. And especially it is important to do a reset after a software update(firmware). Not everyone knows, but the firmware process on their own and in the service center is very different, which is why many people start to run out of battery just after the update. This does not mean that the update is bad, it means that it was not delivered correctly. Therefore, we repeat once again: be sure to reset after the update, this will greatly reduce the likelihood of various troubles with your gadget.

Galaxy S8 tests prove the right of the Korean flagship to carry the title of the best smartphone of 2017, at least for the current date. Infinity Display received the highest marks from independent experts. Iron performance breaks records. A good camera is made even better by software technology called Multi-Frame Image Processing. Today we are talking in detail about these and other achievements of Korean engineers and reinforce the high ratings with tests of the screen, camera, processor and battery.

Galaxy S8 Screen Tests

Infinity Display is the new quality benchmark for smartphone screens. He has a record readability in the sun, even higher than that of his older brother with the plus index. Brightness at standard settings - 440 nits. At maximum settings, the indicator reaches 640 nits. Black color, as befits a screen on a Super Amoled matrix, is really black, not dark gray. For comparison, here are the screen test results of the Galaxy S8, other flagships of 2017 and the best models of last year.

Galaxy S8 display gets top rating A+ from DisplayMate experts. From the UHD Alliance, the screen of the Korean flagship received a certificate Mobile HDR Premium. DisplayMate's highest rating is due to the fact that Infinity Display transmits 142% colors of the standard sRGB color space and 113% DCI-P3 (Digital Cinema Standard) color gamut. Also, the display supports HDR10 technology, although it does not support Dolby Vision.

Color accuracy is excellent. The average color accuracy ratio (DeltaE) was 2 , maximum - total 3.2 (the lower the better). The scores are steeper than the S8+, which had an average color accuracy ratio of 3 and a maximum of over five.

The contrast ratio in the sun is a record 4.768 , which is higher than any smartphone on the market, including the S8+. The flagships of 2016-2017 are behind the competitors. The gap between LG G6 and new products from Huawei is more than significant. Note. Charts do not display correctly in Samsung Internet Browser, older browsers, and some built-in browsers on mobile platforms. We recommend that you open the publication in the latest builds of Google Chrome, Opera, or Firefox.

The Adreno 540 lags behind, as does the 8-core Mali-G71 in . At QHD + resolution, the picture changes somewhat, and the Galaxy S8 falls into the middle of the rating. This is explained by the fact that the graphics adapter at this resolution is forced to calculate 576,000 additional pixels, and the load affects performance.

Galaxy S8: camera test

The Galaxy S8's camera hasn't received a dramatic upgrade over the Galaxy S7, but that doesn't mean nothing has changed. The developers left the Dual Pixel technology and added an algorithm Multi-Frame Image Processing, which improves the quality of pictures in low light.

The algorithm works like this. The Galaxy S8 camera takes several preview photos, then compares the resulting frames and combines them into one shot. A more detailed description of the technology, unfortunately, is not available, but tests of the Galaxy S8 camera show that the detail and quality of images in low light have improved compared to the S7.

As for shooting in good light, there were no problems here and no. Photos are rich and clear, with excellent dynamic range and high detail. Sample photos from the Galaxy S8 camera are in front of you, and you can see 100% crops.

The front camera, unlike the main one, has undergone a major upgrade. Now its resolution is 8 megapixels, which, in combination with aperture 1.7, allows you to take cool selfies in any light. You can read more about the S8 camera in the Galaxy S8+ review (both models received identical camera modules).

Galaxy S8: sound quality test

Can the Galaxy S8 be recommended to audiophiles? In general, yes. When connected to an external amplifier, the smartphone produces a loud and very clear sound. The signal is evenly amplified over the entire frequency range. The signal-to-noise ratio is minimal, as are the coefficients of harmonic and intermodulation distortion.

Excellent sound quality is maintained even when a headset is connected. The distortion is slightly increased, but this is typical for any portable audio device, not just a smartphone. It will not be superfluous to recall that AKG (Harman Kardon) headphones are included with the S8, the retail price of which is about 90 euros. The headphones sound good, and compared to the basic headset of other smartphones, they are completely excellent.

Galaxy S8 battery life test

Galaxy S8 autonomy tests caused concern for many. Thought the battery 3000 mAh a smartphone with a diagonal of 5.8 inches and a resolution of 2960 x 1440 is not enough, but Samsung Galaxy S8 battery tests have refuted the pessimistic forecasts.

In normal operation mode (calls, surfing the web and video playback without fanaticism), the smartphone confidently overcomes the mark of 24 hours, which by modern standards is not just normal, but even good. With a constantly active screen and a modem, that is, with continuous work on the Internet, the Samsung Galaxy S8 battery runs out in about 10 hours. When watching videos on the gorgeous infinity display, the phone lasts longer - 14 hours with a ponytail.

When you enable the Always On Display option, the battery life of the Korean flagship decreases. According to the developers, AOD eats up about 1% of the battery per hour, which affects standby autonomy. The active display time will remain the same, because this function is not required in such a situation.

You will find the autonomy indicators of all flagships 2016-2017 in the material.

Compare Galaxy S8 and S8+

After the tests of the Galaxy S8, we will talk about the chips and features of the smartphone that do not need to be tested with prejudice, and at the same time we will compare the Galaxy S8 and Galaxy S8 +.
