Veredicto - Um forte conceito geral
O Redmi Note 8 é outro smartphone de sucesso da Xiaomi, que oferece muita energia para quem está com orçamento limitado. O hardware que a Xiaomi incluiu por cerca de 150 Euros (~US$ 165) é notável, embora tenha em mente que esse preço se aplica apenas à versão importada. O mesmo se aplica ao seu acabamento de alta qualidade e qualidade de construção, enquanto também somos fãs do seu grande painel IPS. Embora este último não ofereça a taxa de contraste de um painel OLED, ele usa o PWM para regular a luminosidade, o que é um bônus para aqueles que são sensíveis a esse tipo de oscilação.
A Xiaomi também não se comprometeu em nenhuma área, mas o modelo de 128 GB de armazenamento e 6 GB de RAM custa quase o mesmo que o Mi 9T ou o Mi 9 SE. Enquanto o Redmi Note 8 alcança seus irmãos Mi em muitas áreas, ele não pode competir com eles no desempenho da câmera.
O Xiaomi Redmi Note 8 é um smartphone de nível básico triunfante. No entanto, certifique-se de comprar a versão correta.
Uma palavra sobre a compra de uma variante chinesa importada. Em primeiro lugar, você pode incorrer em despesas por trocas ou devoluções caras de garantia, algo que não ocorreria com um aparelho comprado na região local. Em segundo lugar, a versão chinesa do Redmi Note 8 só pode transmitir conteúdo protegido por DRM em definição padrão, uma desvantagem que não afeta o modelo europeu. Por fim, o modelo chinês não vem com Google Play Services pré-instalado, embora possam ser carregados depois. No entanto, poucos smartphones a 200 Euros (~ US$ 220) oferecem tanto quanto o Redmi Note 8, por isso recomendamos sinceramente que verifique a versão europeia se os problemas que afetam o modelo chinês forem um obstáculo para você.
