Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 962 Hz |  | |
| ≤ 99 cd/m² brightness | |||
The display backlight flickers at 962 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 cd/m² and below. There should be no flickering or PWM above this brightness setting. The frequency of 962 Hz is quite high, so most users sensitive to PWM should not notice any flickering. Flickering occurs at relatively low brightness settings, so extended use at this brightness setting or lower can cause eyestrain. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8710 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
O Lenovo Yoga Chromebook C630 é uma poderosa besta 4K que, no final, prova ser demais para o Chrome OS lidar. Embora o C630 seja um dos portáteis com o SO Chrome mais avançado de todos os tempos, a maior parte desse poder é excessiva e prejudica os fatores que fazem os Chromebooks se destacarem no mercado.
Em particular, a duração da bateria é baixa em comparação com os concorrentes e está muito longe do que esperamos de um Chromebook. Além disso, o dispositivo é talvez o Chromebook menos portátil que já testamos. Esse é o preço a pagar por um portátil conversível de 15,6 polegadas. Para uma família de dispositivos que se vende para usuários em em movimento, o C630 fica pesado e desconfortável para transportá-lo de casa para a sala de aula, para o trabalho, para um café.
O C630 não oferece o suficiente para se distanciar significativamente dos concorrentes. O Pixelbook não é muito mais caro e oferece a maioria dessas sutilezas em um pacote mais compacto. O Inspiron Chromebook 14 da Dell tem um formato ligeiramente menor e acompanha o desempenho do Chromebook Yoga C630 pelo mesmo preço. O Inspiron também inclui uma caneta ativa e possui uma das melhores exibições que já vimos em um Chromebook.
Existem algumas coisas boas. Por um lado, a tela 4K é nítida e bonita. Além disso, as opções generosas de RAM e armazenamento "futureproof", o dispositivo como o Chrome OS, inevitavelmente se tornarão mais exigentes no futuro. Considerando os avanços que a Google fez na integração nativa do Android e do Linux no Chrome OS, pode não demorar muito para que os 8 GB de RAM se tornem a norma para os Chromebooks.
Considerando tudo, o Lenovo Yoga Chromebook é um dispositivo competente, mas se sente sobre dimensionado para o software que está executa. Embora a tela 4K, 8 GB de RAM e CPU Core i5 sejam ótimas caixas de verificação para o marketing, eles acabam oferecendo pouco mais do que outros Chromebooks premium. O C630 subsequentemente se sente muito inchado para o Chrome OS. Existem melhores opções nesta faixa de preço.
