Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 595 Hz | ≤ 15 % brightness setting |  |
The display backlight flickers at 595 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 15 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 595 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 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Veredicto – Recomendável, mas não é perfeito
O Redmi 8A novamente oferece muito pelo seu preço acessível: Bateria com duração muito, muito longa, um alto-falante decente, um chassi moderno e estável, patches de segurança atualizados e muito armazenamento. Certamente, você precisará de seu próprio adaptador de força para a função de carregamento rápido anunciado, e o truque para implantar o MIUI 11, mas ainda baseá-lo apenas no Android 9, é bastante audacioso.
As velocidades de localização e Wi-Fi estão no nível da classe, assim como o desempenho em si. Em relação à câmera, existem modelos muito piores por um preço semelhante, para que você possa puxar o gatilho da compra com tranquilidade aqui.
Um smartphone barato com uma ótima configuração: O Xiaomi Redmi 8A é uma recomendação obvia.
Por pouco menos de 120 euros (~US$ 133), dificilmente você pode obter mais pelo dinheiro no momento, mas o Redmi 7A é o dispositivo mais impressionante a um preço ainda mais baixo e com apenas uma pequena quantidade de deficiências. Mas aqueles que procuram uma tela maior, uma duração de bateria ainda mais longa e que preferem um design mais moderno, podem investir os quase 30 Euros (~US$ 33) do preço premium com a consciência limpa.
