Pro
Contra
Nós não esperamos muito na faixa de $200. Desempenho fluente, um chassi robusto e uma tela agradável talvez sejam nossas três principais exigências para um tablet barato "perfeito". No caso de Chuwi, o HiPad faz um “home run” em duas dessas três características.
O chassi de metal é talvez o destaque do HiPad. Seu formato fino e a estética preta e vermelha do tipo gamer dão uma impressão de um tablet mais caro. A tela táctil IPS em vidro também está acima da média em termos de precisão de cor e relação de contraste.
O desempenho é onde o HiPad falha. Ações simples como a rolagem de páginas ou a inicialização de aplicativos têm uma latência não encontrada em tablets mainstream ou smartphones carros-chefe. É aqui que o "orçamento" na categoria de orçamento começa a aparecer. Outros recursos auxiliares, como a câmera fraca, os alto-falantes deficientes e o carregamento lento, são mais fáceis de aceitar nesta faixa de preço, mas um desempenho mais fluente teria tornado a experiência geral do usuário mais perfeita. Felizmente, o tablet ainda é excelente para reprodução de vídeo FHD e para a navegação ocasional que seu público-alvo pode apreciar.
A tela é melhor do que esperávamos em termos de precisão de cor e contraste, para esta faixa de preço. A baixa taxa de quadros e o desempenho lento reduzem um atrativo tablet Android de baixo custo.
