Before launching new products of smartphone manufacturers, including well-known brands, such as Honor, Huawei, Samsung, Sony and Xiaomi, Roskachestvo will definitely examine them for compliance with the declared quality, working with colleagues from ICRT (International Consumer Research and Testing), International Assembly of Consumer Testing Organizations. To date, this association has tested 451 smartphones. During this time, 106 versions of them have already left the market, so now the list of smartphones for sale in the catalog is 345 smartphones. A thorough examination includes even the most seemingly minor issues, for example, the convenience of a packaging box. And also how the device turns on, how conveniently a SIM card is inserted, how quickly the device charges. The unified research rating of ICRT smartphone innovations is recognized worldwide; Representatives of organizations from 26 countries of the world are involved in research tests based on leading European laboratories in this industry with fifty years of experience. Roskachestvo adapts the experience of world research to Russian consumers, focusing on domestic needs. When compiling a rating of smartphones of leading companies, it should be understood that they all passed the same tests on 231 parameters in the same laboratory conditions, therefore, by purchasing a smartphone, consumers have the opportunity to trust the objectivity of these laboratory tests, moreover, the results of such studies allow manufacturers even at the stage of developing new ones models to amend the product line. The consumer can also influence ratings. So, recently the quality of the camera has a great influence on the evaluation of the product; this parameter has a very high weight in the overall assessment of 25%. However, when you get acquainted with the TOP 10 best smartphones, do not rush to turn away from those that are not even in the first half of the list (of more than 300 models). After all, each model has strengths and weaknesses, so the new model is not always the best, and the expensive one is not the highest quality. At the same time, the price-quality ratio should not be discounted. According to the results of tests by Roskachestvo, the top ten smartphones of 2019 were highlighted. Two new Huawei products: P30 and P30 Pro – suddenly burst in and took very high positions in the ranking. Today, the top 10 smartphones look like this: 1. Samsung Galaxy S10 + .2. Samsung Galaxy S10.3. Samsung Galaxy Note 9.4. iPhone XS Max. 5. Huawei P30.6. Samsung Galaxy S10e. 7. iPhone XS. 8. Huawei P30 Pro. 9. Samsung Galaxy S9 + .10. Samsung Galaxy S9.
