O iPhone 8 pode ser o último de seu tipo, o último smartphone da Apple com um botão Home e tela IPS. Se este for o caso, os americanos pelo menos nos deram um excelente capítulo final. Mais uma vez, sentimos falta das grandes novidades ou inovações, mas o iPhone 8 ainda supera o seu antecessor em muitos aspectos. Um fator importante é o novo chip A11, que é mais uma vez muito mais rápido e - como muitos modelos anteriores - fora do alcance dos rivais. A carcaça agora é feita de vidro, o que é ótimo para o toque, mas infelizmente é mais escorregadio e propenso a impressões digitais do que antes (exceto o iPhone 7 Jet Black). Parece que o retorno para um painel traseiro de vidro era necessário para o carregamento sem fio.
A câmera é um destaque real para os entusiastas do vídeo em particular, dado que é a primeira câmera de smartphone com gravação de vídeo Ultra HD a 60 quadros por segundo. Os vídeos Full HD podem ser gravados em até 240 FPS, o que é ótimo para espetaculares vídeos em câmera lenta. A qualidade das fotos está em um nível muito bom e não precisa se esconder atrás dos rivais. O iPhone 8 certamente é o melhor pacote de câmera que você pode adquiri hoje em dia em um smartphone – se gostar do menu de configurações essenciais.
O iPhone 8 é poderoso, dura bastante tempo, e possui uma ótima câmera. Não é necessário fazer uma atualização do iPhone 7, mas as diferenças são mais visíveis quando você vem de um iPhone 6S ou um modelo ainda mais antigo.
Você também recebe LTE veloz, longas durações da bateria, e uma carcaça resistente à água e à poeira. Não pudemos encontrar falhas maiores, mas algumas coisas são irritantes. Isto inclui a garantia limitada e o fraco adaptador de força. A qualidade da voz poderia ser melhor nas redes 3G e o som é apenas médio, apesar dos alto-falantes estéreo.
O movimento da Apple em direção à Realidade Aumentada é importante e certamente será bem sucedido graças à grande plataforma e ao enorme potencial de usuários para avanços rápidos e lucrativos na tecnologia. A RA já funciona bem, mas ainda não é tão precisa ou sofisticada em comparação com a do Asus ZenFone AR, por exemplo.
Em suma, o iPhone 8 é um ótimo produto com componentes de gama alta, mas o smartphone e os acessórios úteis também são muito caros.
