VIVO S1 Amazing design

0 Comments

Vivo recently launched the Vivo Z1 Pro (Review) in India and priced it quite nicely. This smartphone managed to fare quite well when we reviewed it. Now, the Chinese manufacturer has launched yet another smartphone priced only a little higher, dubbed the Vivo S1. That is clearly a section of the brand new S series which means Style. The Vivo S1 is stylish for sure, but is there the performance to back its looks? We test that to find out.

Vivo S1 design

Vivo smartphones are usually sleek and well designed, which one is no exception. The Vivo S1 sports a 6.38-inch display with just a little dewdrop-style notch at the very top. Vivo has chosen an AMOLED panel, and the Vivo S1 sports an in-display fingerprint scanner. The display has thin bezels on the sides nevertheless the bottom chin is comparatively thicker.

The Vivo S1 is available in two colours, Diamond Black and Skyline Blue and we had the Diamond Black unit for that reason review. It includes a laminate back with a striking diamond pattern design and a gradient colour finish. Based on the way the light hits the trunk panel, the diamond patterns emerge, which does look catchy.

However, we aren’t a huge fan of the material that the back panel of the Vivo S1 is constructed of, as it picks up scratches easily. We’d have preferred Corning Gorilla Glass, as seen on the Redmi Note 7 Pro (Review). The Vivo S1 carries a triple camera module which protrudes slightly but has a metal rim around it which should save it from getting scratched.

Vivo has chosen a plastic frame that’s rounded making the smartphone comfortable to carry in the hand. The trunk does not meet the frame seamlessly, and you may feel rough edges when holding the phone. Vivo has positioned the energy button to the right combined with the volume buttons, and they’re all an easy task to reach. The Vivo S1 offers a dedicated Google Assistant button similar to the one on the Vivo Z1 Pro.

We were disappointed by using a Micro-USB port on the Vivo S1, considering that most other smartphones around this price point have moved to USB Type-C. The Micro-USB port is put at the bottom combined with the loudspeaker and the 3.5mm headphone jack, as the SIM tray is on the left side.

Vivo S1 specifications and software

The Vivo S1 could be the first smartphone in India to be powered by the newest MediaTek Helio P65 SoC. The Helio P65 is often a mid-range processor based on a 12nm process. It has a couple of ARM Cortex-A75 cores clocked at 2GHz, and six Cortex-A55 cores clocked at 1.7GHz. For graphics, it has a Mali-G52 integrated GPU.

Vivo has launched three variants of the Vivo S1 in India: the entry-level one with 4GB of RAM and128GB of storage; another with 6GB of RAM but 64GB of storage; and the top-end one with 6GB of RAM and 128GB of storage. These variants are priced at Rs. 17,990, Rs. 18,990 and Rs. 19,990 respectively. We’d the most notable variant in for review also it had near 100GB of storage available from your box. The pricing of the Vivo S1 pits it directly against powerful phones such as the Realme X (Review) and the Oppo K3 (Review).

The Vivo S1 is a dual-SIM device and contains two Nano-SIM slots as well as a dedicated microSD card slot. Connectivity options on the Vivo S1 include Bluetooth 5, dual-band Wi-Fi, GPS, Radio, dual 4G VoLTE, and the most frequent sensors. The Vivo S1 packs in a 4500mAh battery so you get an 18W fast charger in the box.

The Vivo S1 runs Funtouch OS along with Android 9 Pie, that’s heavily customised. If you do used a Vivo smartphone before, it won’t take long for one to find your way around the device. You can read in detail about Funtouch OS within our Vivo Y17 review. To begin with, there is no app drawer and all app icons are prearranged on the house screens. Funtouch posseses an iOS-like Command Center which needs a swipe up from underneath of the screen to gain access to. This can be the precise opposite action compared to other Android smartphones and may be annoying to some people.

Vivo does use a fair amount of bloatware on these devices, and we saw DailyHunt, Helo, Facebook, Gaana, Amazon Shopping, PhonePe, Paytm, and some other apps preinstalled. Thankfully, this phone did not have a notification spam issue similar to the Oppo A9 (Review) we recently reviewed. Vivo offers its own app store called the V-Appstore.

Vivo S1 performance, battery life, and cameras
The MediaTek Helio P65 SoC powering the Vivo S1 does an excellent job and you also won’t notice lag or stutter doing day-to-day tasks. This smartphone is quick to launch apps and can run most apps and games out there on the Google Play Store. We never had to wait too long for an app to open. It also manages idle battery drain well, and in our experience, the Vivo S1 didn’t lose an excessive amount of its charge when sitting idle. Multitasking was rather easy considering we’d the 6GB RAM variant of the devices. The phone never had to close apps running in the background.

The AMOLED panel on the Vivo S1 had good viewing angles and was bright enough to be legible outdoors. However, the bottom-firing speaker isn’t that loud, evoking the Vivo S1 to flunk of being an excellent device to take content on. We also tested the in-display fingerprint scanner in addition to the face recognition feature with this device. The in-display scanner is quick to scan a finger and unlock the smartphone, and rarely required another attempt. Face Unlock isn’t probably the most secure approach to unlocking the smartphone, nevertheless it is quite quick and convenient.

Vivo S1 were able to clock 146,142 in AnTuTu benchmark which wasn’t significantly higher than the 145,999 scored by the Oppo A9. The Vivo S1 managed 1,853 and 6,034 in Geekbench 4’s single-core and multi-core tests respectively. In graphics benchmarks, the smartphone scored 36fps in GFXBench T-Rex and 12fps in GFXBench Manhattan 3.1.

PUBG Mobile ran at the medium preset on the Vivo S1 with the graphics set to Balanced and the frame rate set to Medium. We played the overall game for 20 minutes which did cause the telephone to get warm to the touch. We also noticed a 5 percent battery drop after gaming for that long.

The Vivo S1 delivers good battery life and we could go on for about each day and a half a comparable charge. During this cycle, we ran all our benchmarks, took several camera samples, and had a dynamic WhatsApp account on the device. Within our HD video loop test, the smartphone could actually last for 16 hours and 38 minutes. We put the supplied charger to the test and it were able to charge the battery to 34 percent in 30 minutes and 65 percent within an hour.

Vivo has chosen a triple camera setup on the trunk of the Vivo S1. This includes a 16-megapixel primary camera with an f/1.78 aperture, an 8-megapixel ultra-wide-angle camera having an f/2.2 aperture, and a 2-megapixel depth sensor having an f/2.4 aperture. At the front end, this phone includes a 32-megapixel selfie shooter having an f/2.0 aperture.

The camera app is comparable to what we’ve seen on the Vivo Z1 Pro and contains multiple modes to choose from. vivo s1 has quick toggles for HDR, Live Photo, Filters, aperture mode, and a toggle to switch between the regular and the wide-angle lens. Apart from the photo and video modes it provides Pano, AR Stickers, Fun Video, Document, and an expert mode. Fun Video adds background audio when you record a video.


Photos taken with the Vivo S1 were substandard for a smartphone at this price point. In daylight, the phone focused quickly but we remarked that photos were underexposed. Details were acceptable, and text a long way away was legible. Exactly the same scene was exposed better when using the ultra-wide-angle sensor. However, in cases like this, photos lost from details.
