Contra
O LG Gram 15Z980 é incomparável para a coroa de portáteis finos e leves de 15 polegadas. Existem compromissos que vêm com este dispositivo de 1,1 kg (~2,4 lbs). Em geral, gostamos da abordagem da LG para tornar o dispositivo mais leve, mas não tornando o dispositivo mais fino em consequência.
A carcaça de liga de magnésio parece premium, mas é suscetível a pressão e torção. A combinação do material e o baixo peso faz com que o dispositivo pareça frágil. No entanto, os testes de resistência e certificação MIL-STD-810G dos populares canais do YouTube ajudam a combater essa impressão.
No geral, o LG Gram 15Z980 é um impressionante cavalo de batalha ultra-móvel que é extremamente leve e oferece ótima duração da bateria. É uma pena que a LG não ofereça o dispositivo em mais mercados.
Além disso, o 15Z980 não consegue fazer uso pleno da sua CPU Core i7-8550U. O nosso dispositivo de teste apenas correspondia aos concorrentes com Core i5-8250U em benchmarks. Além disso, a LG equipou nosso dispositivo de teste com um SSD SATA III lento que não pode competir com unidades NVMe muito mais rápidas. Infelizmente, o dispositivo aceita apenas o padrão SATA III mais lento. Um belo toque é o segundo M.2-2280, caso precise.
Há muitos outros aspectos positivos também. A RAM de 16 GB operando no modo de canal duplo ajuda a extrair o máximo da GPU integrada. O 15Z980 oferece também uma sólida seleção de portas, incluindo três portas USB 3.0 tipo A e uma porta Thunderbolt 3.
O teclado oferece uma boa experiência de digitação geral, mas levará algum tempo para se acostumar. Existem alguns tamanhos de teclas não padrão que parecerão estranhos no início. Além disso, só poderíamos escolher um teclado QWERTY em espanhol. No entanto, a inclusão de um teclado numérico é útil, especialmente porque nem todos os dispositivos de 15 polegadas incluem um.
A tela Full HD é suficientemente brilhante com uma boa relação de contraste e precisão de cor decente. Frustrantemente, o brilho máximo é reduzido significativamente com a bateria. Poderia haver uma configuração em algum lugar para corrigir isso, mas não conseguimos encontrar durante o teste. Isto combinado com uma tela altamente refletiva, faz com que usar o 15Z980 em exteriores seja desconfortável.
Além disso, nosso dispositivo de teste permanece relativamente frio e silencioso, mesmo sob condições de uso intenso. Além disso, o 15Z980 possui uma duração de bateria excepcionalmente longa que derrota facilmente nossos dispositivos de comparação.
Curiosamente, o 15Z980 teria marcado 84% como um portátil de escritório, mas 86% como um sub-portátil. Decidimos classificar o dispositivo na última categoria por causa de sua mobilidade em comparação com outros dispositivos de 15 polegadas.
