How handed “Guardian”, citing the results of research funded by the European Union, Samsung TVs can actually be less efficient than provided by the manufacturer. There is circumstantial evidence pointing to the existence of solutions, resulting in reduction of power consumption only in tests. Representative of the European Environmental Bureau compared the matter to the scandal over manipulation emissions tests by Volkswagen. Not everything here is not entirely clear.
- Samsung sticks to the letter of the law but not the spirit of the law – said opisującemu cause “Guardian” Heinz Rudolf of ComplianTV. Laboratory that carried out the study, found that used in Samsung’s new TVs Dynamic mode the backlight can affect the results of the official test power consumption, carried out before placing devices on the market.
This mode is used to ensure that lower the brightness of the image when viewing fast motion footage certain kind. According to the manufacturer it was established in order to effectively reduce current consumption of the device. As, however, says, “The Guardian”, citing the results of an unpublished report publicly ComplianTV, during testing it was noted that he has a special efficacy in test cases.
The product tests carried out by the International Electrotechnical Commission (IEC) used are rapidly changing materials. Described mode reacts very effectively. In their case, followed by its associated limit energy consumption. In normal use of the TV is not noticed his supposedly high efficiency, which can lead to suspicions that the sole objective existence of that mode is manipulating the results of measurements.
At the same time, however, representatives of ComplianTV emphasize that they have no evidence to prove that Samsung’s technology actually “senses” a test case and changes on the basis of the TV. They saw only the TV’s make such an impression .
Samsung in turn ensures that the accusations are unfounded and described mode can not in any event be likened to fraud Volkswagen. Below is a statement we received from Olaf Krynicki, spokesman of Samsung Electronics in Poland
We firmly reject suggestions that our TVs are equipped with a mechanism designed to interfere with the measurement of energy consumption. It is not possible to test synthetic and real consumption differed from each other.
Auto Motion Plus, the current Smart TV from 2011, actually reduces energy consumption. Not only becomes active when measuring power consumption, by contrast, is enabled by default right out of the box – either at home or in the laboratory. It is an option that can obviously off by going to the user settings, but in standard mode is the default setting.
Dynamic backlight is one of the elements of the system that we have developed with the aim of reducing the impact of electronic devices on the environment. We are extremely proud of these technologies and we intend to develop them.
It may therefore be that all the fuss is merely a storm in a teacup, and the “Guardian” exaggerates or even distort test results ComplianTV. Yes seems to regard Samsung, which ensures that the function referred, it is also useful outside of test cases.
We have also decided to ask what then, is the principle of the Auto Motion Plus. Krynicki Olaf explains:
Our technology works irrespective of the conditions of use. It is not important whether the video is watched by employees of IEC (International Electrotechnical Commission) or any other person. IEC is used for testing a wide variety of video content – both very dynamic and static. This is to simulate how real-world device will be used.
Our research teams have made a series of measurements using a variety of video content – from fast action scenes and sports, the classic material-TV (news, weather, etc …) to show images. The results of the energy consumption vary depending on the type of the display material. Exactly the same results were achieved by teams IEC.
In the manual (also available in the TV menu) energy saving options are accurately described, we give also a way to turn them on and off. Energy class are communicated in a manner required by law. They are determined on the basis of the standardized and repeatable tests that simulate the energy consumption in a domestic environment. This process manages the organization of the International Electrotechnical Commission. Each producer is here treated in the same way that the customer can find a fair comparison of commercially available devices.
Regardless of the merits of the accusations “Guardian”, the whole thing has already begun to stagger wider. The European Commission in response to these reports – true or not – has already announced modify the rules used in the tests. It wants to clearly and explicitly prohibited action was another TV in the tests than in reality. Any device designed to research behave differently than in normal use, would be deemed to comply with standards. The Commission does not deal with in this case the truth of just these specific allegations – wishes, however, that in case of detection of such cases could be immediately punished.
It is also worth mentioning at this point that Samsung’s case is not the first the announcement of this type of segment electronics. Earlier this year, it reported a similar problem Swedish Energy Agency, which suspected unnamed manufacturers of manipulating the results of tests power consumption. She then asked the European Commission to further study the matter.
The European Union in response to the reports “The Guardian” has announced to conduct further, more in-depth testing, having to answer the question of how serious and widespread this may be a problem.
At the beginning of 2014 detected artificially drive test results by Samsung mobile phones. The company has applied, among others, Galaxy S4 and Note 3 mechanism that after detecting the operation of one of the popular benchmarks increased processor performance up to 100 percent. without consuming the battery. It made handsets fared better in tests than in normal use, which uses energy-saving mechanisms. The company has discontinued these practices on a broad describing them in industry publications.
