Tomorrow (March 30), Vivo will announce the much-anticipated Vivo X300 Ultra in China. Alongside it, the company is also set to introduce the Vivo X300s and the Vivo Pad 6 Pro. Just ahead of the launch, a new poster shared by Product Manager Han Boxiao has revealed key hardware details of the X300s, giving a clearer idea of what to expect from the device.

Vivo X300s key specifications confirmed

The official teaser confirms that the Vivo X300s will be powered by the MediaTek Dimensity 9500 chipset, paired with the brand’s in-house V3+ imaging chip. The device will feature a 6.78-inch flat display tuned with Zeiss color calibration, offering a 144Hz refresh rate for smoother visuals. Audio performance is expected to be enhanced through dual stereo speakers with advanced tuning.

The phone is also set to include a large 7,100mAh battery, which is notably higher than what is typically seen in this segment. Thermal management will be handled by a large-area VC liquid cooling system, aimed at maintaining stable performance during extended use. Vivo has also highlighted a new signal amplification system for improved connectivity. The poster also shows color options, such as light green, lavender, white, and dark grey.

Apart from the confirmed specifications, the Vivo X300s is said to feature a 50-megapixel front camera. On the rear, it may include a triple camera setup comprising a 200-megapixel main sensor with OIS, a 50-megapixel ultra-wide lens, and a 50-megapixel periscope telephoto camera with OIS. This setup suggests a strong focus on versatile photography.

The device is also expected to support 90W wired and 40W wireless charging. Additional features could include an ultrasonic in-display fingerprint sensor, a USB-C Gen 3.2 port, and an IP68 and IP69-rated body for durability.

On April 1, Oppo will announce the Oppo K15 Pro and K15 Pro+ in China. Ahead of the launch, both phones are now listed for pre-orders through the company’s online store. The official listings have revealed their configurations and color options. At the same time, both devices have appeared on Geekbench, confirming their chipsets.

Oppo K15 Pro series configs, color options

The official images of the Oppo K15 Pro and K15 Pro+ show that both phones have an identical design. For those who don’t know, the K15 Pro will be a smaller device featuring a 6.59-inch screen, whereas the K15 Pro+ will have a larger 6.78-inch display.

The K15 Pro and K15 Pro+ will come in shades such as Cyber Wings, Origin Gray, and Photodust (pink). The Pro version will also be available in an additional Golden Legend color variant. Both phones will be offered in 12GB+256GB and 12GB+512GB configurations.

Both phones are also listed on Geekbench with model numbers PHM110 and PGM110, respectively. The previously seen TENAA listings revealed that these devices are powered by 3.40GHz octa-core and 3.73GHz octa-core chips, respectively.

The Geekbench listings confirm that these devices are powered by the Dimensity 8500 and Dimensity 9500s, respectively. Although the chipset names are not explicitly mentioned, the CPU and GPU details available in the listings are sufficient to confirm their identities. The listings further reveal that the K15 Pro series comes with 12GB of RAM and runs on Android 16.

Other reports suggest that the K15 Pro series will support a 1.5K resolution and up to a 165Hz refresh rate. Both phones are also expected to feature a built-in cooling fan, a 16-megapixel front camera, and a 50-megapixel + 8-megapixel dual-camera setup. The K15 Pro may house a 7,600mAh battery, while the Pro+ variant may feature an 8,000mAh battery, and both are likely to support 80W charging.

Chinese image sensor maker SmartSens has introduced a new camera sensor aimed at flagship smartphones. The SC5A6XS brings a 50-megapixel 1-inch format and focuses on improving dynamic range and video capabilities. The announcement highlights upgrades in HDR processing, low-light imaging, and power efficiency, setting the stage for next-generation mobile photography.

Focus on HDR and video performance

The SC5A6XS is built on a 22nm stacked process and integrates the brand’s upgraded Lofic HDR 3.0 technology. This system enhances image quality in challenging lighting by capturing a wider range of brightness levels. With a peak dynamic range of 115dB, the sensor aims to preserve highlight details while retaining shadow information in high-contrast scenes.

The HDR system works through multi-frame fusion within a single exposure, which also helps reduce motion artefacts. This is particularly useful in video scenarios where subjects or the camera are in motion. The sensor supports 4K video at 120fps, along with 4K 60fps recording in HDR mode, making it suitable for advanced video use cases on smartphones.

In terms of hardware, the sensor features a 1.6μm pixel size and incorporates SFCPixel technology to improve light sensitivity. With higher sensitivity and reduced read noise, it is designed to produce clearer images in dim conditions without excessive grain.

Autofocus is handled through a combination of full-pixel AllPix ADAF and partial pixel phase detection, allowing faster and more reliable focusing across different lighting environments. Additionally, the company has worked on reducing power consumption, with an approximate 11 percent improvement in HDR mode, which may help control device heating during extended video recording.

The SC5A6XS has already entered the sampling phase and is expected to move into mass production in the second quarter of 2026. It is likely to appear in upcoming flagship smartphones, probably the Huawei Pura 90 series, being the likely candidate, focusing heavily on camera performance.

What are your thoughts on the new 1-inch 50-megapixel SC5A6XS sensor and its HDR capabilities?
