Vivo S1 Pro

Vivo's S1 Pro places a strong emphasis on style, and in this aspect, it certainly excels. The phone boasts an attractive design with its distinct diamond-shaped camera module. Despite measuring 8.68mm in thickness, it's slightly weighty. A 6.38-inch Super AMOLED display graces the front, offering full-HD+ resolution. The convenience of an in-display fingerprint sensor is also on offer, which performs well.

Under the hood, a Snapdragon 665 octa-core SoC powers the device alongside 8GB of RAM and 128GB of storage. The software experience is delivered through Funtouch OS 9.2, based on Android 9 Pie. Unfortunately, a fair amount of pre-installed bloatware can be frustrating. Performance is generally satisfactory, although gaming can lead to a bit of heat buildup.

Battery endurance proves solid, with the 4,500mAh battery easily sustaining a day and a half of regular use. On the photography front, a primary 48-megapixel camera with an f/1.8 aperture captures images. In favorable lighting conditions, image quality holds up well, although it dips in low-light scenarios. When it comes to selfies, the front-facing camera delivers impressive results, particularly in daylight conditions.

Reviews

Vivo S1 Pro design and display

The Vivo S1 Pro carries on the tradition of being an aesthetically pleasing device, maintaining the legacy of its predecessor, the Vivo S1. While the distinctive diamond pattern on the back has been replaced, the S1 Pro offers a range of captivating gradient finishes. Our variant, named 'Jazzy Blue,' is accompanied by 'Dreamy White' and 'Mystic Black' options. Although slightly robust at 8.68mm in thickness, the phone's 186g weight becomes noticeable during prolonged one-handed usage. The device's contoured edges and gradually curving back contribute to a comfortable grip, with the glossy finish managing to avoid excessive slipperiness. Notably, the back isn't composed of glass; Vivo continues to utilize laminated plastic for this purpose.

On the front, a 6.38-inch Super AMOLED display graces the device, offering full-HD+ resolution. The integrated in-display fingerprint sensor functions efficiently, accompanied by a selection of visually appealing unlock animations. While the presence of face unlock adds another layer of security, it's not as swift as comparable implementations seen in other smartphones within this price range. The pre-applied screen protector, while a thoughtful addition, can be irksome due to its tendency to graze against the skin during gesture-based interactions.

The button layout on the Vivo S1 Pro is well-executed. Positioned on the left is a tray capable of accommodating either two Nano-SIM cards or a single Nano-SIM along with a microSD card. However, a separate slot dedicated solely to memory expansion would have been preferable. The bottom houses a USB Type-C port and a speaker, while the top features a headphone jack. The rear of the phone showcases its unique design elements. In addition to the captivating color scheme, the slim camera module stands out for its minimalist profile, barely protruding from the body. Adjacent to the module is the LED flash, complemented by Vivo's logo and tagline just below.

Inside the box, the Vivo S1 Pro arrives with a customary set of accessories, including a silicone case, Type-C cable, 18W charger and handset.

Vivo S1 Pro performance and battery life

The Vivo S1 Pro steps up as a reliable daily companion with a design that's sure to grab attention. Setting it apart from its segment peers, the camera module's unique aesthetic deviates from the commonplace vertical camera arrays. The display's impressive brightness ensures excellent legibility, even in direct sunlight. Vivid colors owing to the AMOLED panel and well-defined text and icons add to the display's appeal. The Snapdragon 665 handles multitasking adeptly, although it's not the most robust chip for demanding gaming scenarios.

PUBG Mobile struggled to maintain a smooth framerate even at the Low graphics preset. While playable, the game experienced occasional jerkiness. Thankfully, overheating was not an issue, even after an extended 30-minute gaming session. The singular speaker isn't exceedingly loud, producing somewhat tinny audio. Nonetheless, the vibrant display enhances the video viewing experience. The Vivo S1 Pro is equipped with a 4,500mAh battery that comfortably extends over a day and a half, even with intensive usage. Our HD video battery loop test attested to its stamina, clocking in at an impressive 17 hours and 7 minutes. While Vivo's Dual Engine Fast Charge feature is in place, the included charger doesn't deliver swift refueling for such a sizable battery. In testing, the S1 Pro reached 31 percent in half an hour and approximately 61 percent in an hour, while a full charge took about two and a half hours.

Turning to its camera capabilities, the Vivo S1 Pro boasts an array of four rear cameras: a 48-megapixel primary camera with an f/1.8 aperture, an 8-megapixel wide-angle camera with an f/2.2 aperture, a 2-megapixel macro camera, and a 2-megapixel depth sensor. On the front, a 32-megapixel selfie camera with an f/2.0 aperture takes the spotlight. Navigating the camera app is intuitive, with primary shooting modes placed conveniently above the shutter button. However, important controls for features like the ultra-wide camera, bokeh, and macro modes reside in a separate carousel menu, requiring extra taps for access—this setup wasn't particularly user-friendly during our usage.

In well-lit conditions, the Vivo S1 Pro captures serviceable landscape shots, offering decent detail and acceptable colors, though images may lack depth. Instances of grain can be noted at the frame's edges. While HDR intervenes when necessary, its results aren't consistently impressive. Some images exhibit an unnatural bluish hue. Close-ups fare better, delivering appealing bokeh and detailed objects. The wide-angle camera introduces an interesting perspective but may exhibit inaccuracies in color representation.
