Some smartphones have a tendency to float into obscurity after a few launches in an ever-evolving market where the phone landscape is constantly changing. Despite all of this, it is quite clear that the Huawei Y9s, released in late 2019, remains incredibly appealing even in 2024. Even though the Y9s do not have the thinnest bezels or the most premium materials, its design remains unobtrusive despite its modest price tag. The Huawei Y9s features a 6.59-inch IPS LCD display with a resolution of 1080 x 2340 pixels. It is pleasant to watch videos and browse the web on this device, and the display gets sufficiently bright to be used outdoors. As far as battery life is concerned, the Y9s have one of the best batteries on the market. It has an impressive 4,000mAh battery, which can easily hold the device for an entire day, even if it is used moderately.
