Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 65790 Hz | ≤ 6 % brightness setting |  |
The display backlight flickers at 65790 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 6 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 65790 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Veredicto - Totalmente melhorado
A versão 2020 do Fire HD 8 tem melhorias significativas de desempenho e um design um pouco mais moderno do que seu antecessor, o Fire HD 8 (2018). Pelo preço cotado, o equipamento não só está à altura dos concorrentes, mas também pode superá-los em algumas áreas como a velocidade WLAN. Além disso, o novo modelo tem duração de bateria significativamente melhor, que permite mais de 15 horas de autonomia, o que supera totalmente seu modelo anterior.
A Amazon melhora o Fire HD8 em todos os aspectos, mas ainda mantém seu preço baixo.
Independentemente do usuário optar por ter ou se livrar das "ofertas especiais", graças ao FireOS fortemente adaptado, o Fire HD 8 (2020) vale principalmente para clientes da Amazon que também fazem uso extensivo dos serviços da empresa. Dado que agora existem boas alternativas, como o Lenovo Tab M8 HD nesta faixa de preço, os usuários que desejam um tablet barato e de alto desempenho não precisam necessariamente comprar um dispositivo Fire. Mas se você possui um Fire HD 8 (2018) e gosta de usá-lo, vale a pena mudar para o modelo 2020, pois o desempenho melhorou totalmente.
