Veredicto - O Xiaomi Redmi 8 define novos padrões para smartphones econômicos
O Redmi 8, que é muito semelhante ao Redmi 8A no papel, é uma atualização significativa em relação a seus irmãos, mesmo que pareçam quase idênticos. O primeiro não apenas possui câmeras aprimoradas e um alto-falante melhor, mas também possui melhor conectividade e uma tela visivelmente melhorada. No geral, embora tenhamos recomendado o Redmi 8A mais barato ao analisá-lo, o Redmi 8 oferece uma relação custo/benefício ainda melhor. Em suma, o mais recente smartphone Redmi de orçamento da Xiaomi define novos padrões para smartphones abaixo de 120 euros (~US$ 133), principalmente porque não possui deficiências sérias.
No entanto, a Xiaomi fez alguns compromissos, o que não é de surpreender, considerando o baixo preço recomendado do dispositivo. O Redmi 8 é e continua sendo um smartphone de nível de entrada. Consequentemente, a Xiaomi equipou o dispositivo com um SoC fraco, uma tela de baixa resolução, armazenamento flash eMMC e um módulo Wi-Fi lento. Por apenas 30 Euros (~US$ 33) a mais, o Redmi Note 8 é uma alternativa interessante ao Redmi 8, pois oferece desempenho notavelmente melhor com quase nenhum esforço maior.
O Xiaomi Redmi 8 oferece mais do que a maioria dos smartphones abaixo de 120 euros (~US$ 133). Se o preço é o fator limitante para o seu próximo smartphone, o Redmi 8 seria uma boa opção.
