Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 384.6 Hz | ≤ 10 % brightness setting | |
The display backlight flickers at 384.6 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 10 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 384.6 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured. |

Veredicto – Tão acessível e tão potente
Os telefones Redmi da Xiaomi são cortadores de preços - eles continuamente estabelecem novos padrões em sua faixa de preço: O Remi 7A está disponível por cerca de US$ 100 (dependendo da configuração) e oferece recursos que normalmente só vemos em smartphones que são o dobro do preço. Por exemplo, o telefone funciona com um Snapdragon 439, um SoC poderoso que oferece muito valor pelo seu dinheiro. A duração da bateria muito longa, os grandes alto-falantes e a adequação aos jogos completam o conjunto de excelentes recursos. A câmera tira fotos decentes, a tela é brilhante e o aquecimento é tolerável sob carga. As novas opções de cores dão ao telefone Xiaomi um visual moderno e fresco que também é muito confortável de segurar. Graças à função de carga rápida, o smartphone também recarrega rapidamente.
É uma coleção de pontos fortes para um dispositivo tão acessível e dificilmente qualquer concorrente nessa faixa de preço pode igualar-se a ele. O telefone inclusive supera o seu antecessor com uma maior duração da bateria e maior desempenho. O fato de os modelos Redmi A não estarem equipados com um leitor de digitais é uma vergonha, no entanto, assim como o GPS impreciso e o fone ligeiramente abafado.
Se você está procurando por um smartphone acessível e ainda quer um bom desempenho e uma bateria de longa duração, o Redmi 7A pode ser o telefone certo para você.
Podemos definitivamente recomendar o Xiaomi Redmi 7A. Apenas certifique-se de comprar a versão global de um revendedor confiável, pois você pode ter problemas com o adaptador de CA e a garantia.
