Technical specifications
Display & performance The smartphone is equipped with a 6.75-inch IPS LCD display that features a fluid 120Hz refresh rate and a peak high brightness mode of 1250 nits. The screen has a native resolution of 720 × 1570 pixels in a 19.5:9 aspect ratio, yielding a pixel density of roughly 256 ppi and achieving an 85.3% screen-to-body ratio. Under the hood, the phone is powered by a Qualcomm Snapdragon 6s 4G Gen 2 chipset, which utilizes an octa-core CPU configuration consisting of four performance Cortex-A73 cores clocked at 2.9 GHz and four efficiency Cortex-A53 cores clocked at 1.9 GHz alongside an unspecified Adreno GPU.
Memory For memory and internal storage, the device implements fast UFS 2.2 architecture and is available in configurations of either 128 GB or 256 GB of storage paired with 6 GB or 8 GB of RAM; however, it lacks a dedicated microSD card slot for expandable storage.
Cameras & battery The camera array on the rear includes a dual system headlined by a 50 MP wide-angle lens with an f/2.0 aperture and Phase Detection Autofocus, supported by an auxiliary lens and an LED flash capable of shooting 1080p video at 30 frames per second. On the front, it has a single 8 MP wide camera with an f/2.1 aperture. One of the device's standout hardware characteristics is its massive 7200 mAh silicon-carbon battery, which supports 44W wired fast charging capable of reaching a 50% charge in 43 minutes, as well as reverse wired charging and a specialized bypass charging mode.
Software Out of the box, it operates on the Android 16 platform customized with vivo's proprietary OriginOS 6 user interface, integrated with Origin Island and vivo DocMaster.
