vivo X90

The Vivo X90 is the standard variant of Vivo's flagship lineup, boasting impressive upgrades over its predecessor. Despite shipping attention towards Xiaomi's Digital Series, Vivo has successfully created an efficient smartphone with the X90. With a 6.78-inch Boe Q9 display, the X90 offers a 1260p resolution and 1300 nits peak brightness, providing a comfortable visual experience in low light conditions. The phone also features a new Zs T coating for its triple lenses, which enhances photo and video quality in extreme low light conditions. Under the hood, the X90 is powered by the MediaTek Dimensity 9200 chipset, delivering impressive performance in benchmarks. In Geekbench 5, the X90 achieves a 15% boost in single-core performance, while in 3D Mark GPU tests, it surpasses an iPhone 14 Pro's A16 chip. The camera performance is surprisingly decent, with the same triple lenses as its predecessor, but the new Zs T coating and V2 image chip deliver enhanced photos and videos. The battery life is also satisfactory, with a 4800mAh capacity and 120W fast charging capabilities. While not without its drawbacks, the Vivo X90 is poised to become one of the best flagship killers of 2023, with its impressive performance, camera capabilities, and feature-packed design making it a compelling choice for Android enthusiasts.
