The vivo S2 is the phone vivo fans in India have been waiting seven years for. The S series was put to sleep after the vivo S1 launched back in August 2019, and it took until August 6, 2026 for vivo to finally bring it back with the S2. The pitch is simple: a flagship-inspired design, a huge 7,050mAh battery, a 1.5K curved display, and a 50MP Sony main camera with 4K video on both the front and back — all for ₹39,999 (roughly ₱25,600).
After spending time with the phone, here’s my full vivo S2 review: what it gets right, where it cuts corners, and whether the S series comeback is actually worth your money.
Design & Build Quality
The first thing you notice about the vivo S2 is how slim it is. At just 7.99mm and 197 grams, it carries a 7,050mAh battery — one of the biggest in its class — without feeling like a brick. The Sapphire Blue and Regal Bronze versions weigh 197g, while the Silk White is slightly thicker at 8.10mm and 199g.
The back uses a matte plastic composite sheet instead of glass, which is a deliberate trade-off. You don’t get that premium glass feel, but the phone picks up almost no fingerprints, and it survives drops better. vivo says the S2 passed five MIL-STD-810H military-grade durability tests, including drops from one meter onto granite, tile, wood, and steel. That’s the kind of durability you normally don’t expect from a phone that looks this elegant.
Around the back sits the Skyline camera module — a horizontally aligned island holding two lenses and the circular Aura Light flash. If it reminds you of a Google Pixel’s camera bar, that’s the point. It’s a distinctive look that helps the S2 stand out from the usual vertical camera stacks, and the Aura Light ring flash doubles as a softer, more even light for portraits.
Durability is a genuine highlight here: IP68 and IP69 ratings mean the phone survives both full immersion and high-pressure water jets. There’s even Wet-Hand Touch, Greasy-Hand Touch, and Rain Protection, so the display keeps responding when your hands are wet or it’s pouring outside. For a country like the Philippines where sudden rain is a daily reality, that’s more useful than it sounds.
Display
The vivo S2 packs a 6.83-inch 3D curved AMOLED panel with 1.5K resolution (2,800 x 1,260 pixels, roughly 450ppi) and a 120Hz refresh rate. Text looks crisp, colors are rich and vibrant, and the deep AMOLED blacks make video streaming a pleasure. The curved edges flow into the frame nicely and the phone sits comfortably in the palm.
vivo quotes up to 3,000 nits of local peak brightness, and the panel carries an SGS Five-Star Sunlight-Readable certification. I tested this on a bright afternoon and the screen stayed perfectly readable outdoors — a real difference-maker for commuters who use their phone in direct sunlight. The panel also has SGS Low Blue Light and Low Flicker certifications, so late-night scrolling is easier on the eyes.
The display supports HDR10+ playback, and with the symmetrical dual stereo speakers — one at each end, not just an earpiece masquerading as a speaker — the S2 delivers a genuinely immersive multimedia experience. Watching Netflix or playing games on this phone sounds fuller than most mid-rangers.
Performance
Under the hood sits the MediaTek Dimensity 7360-Turbo, a 4nm octa-core chip with four performance cores clocked at up to 2.5GHz and four efficiency cores at 2.0GHz, paired with the Mali-G615 MC2 GPU. It’s a customized version of the Dimensity 7360 with extra vendor-level tuning for smoother gaming and better sustained performance.
vivo claims an AnTuTu score of around 970,000, which puts the S2 in the upper mid-range tier. In day-to-day use, the phone feels genuinely fast: apps launch quickly, multitasking is fluid, and the 120Hz display keeps every animation smooth. The 8GB of LPDDR4X RAM can be extended by up to 8GB of virtual RAM, though I’d have preferred the faster LPDDR5 at this price — it’s one of the few places the S2 clearly cuts a corner.
For gaming, the S2 handles BGMI, Call of Duty Mobile, Mobile Legends, and Free Fire without major issues. vivo claims a stable 90 FPS in BGMI for up to three hours, and the 3,800mm² vapor chamber cooling system keeps things comfortable — heat spreads evenly across the chassis rather than pooling around the camera. Bypass charging also lets the phone power directly from the wall when the battery is above 20%, which keeps temperatures down during long gaming sessions.
If you’re a heavy gamer chasing flagship frame rates, this isn’t the phone for you — the Dimensity 7360-Turbo is a smooth everyday chip, not a gaming monster. But for 95% of users, it’s more than enough.
Camera
The camera is where the S2 wants to shine. The main shooter is a 50MP Sony sensor with an f/1.8 aperture — GSMArena lists it as the IMX582, while Indian outlets report the IMX852 with optical image stabilization, so there’s some discrepancy in the exact sensor depending on the source. The camera delivers pleasing colors with natural contrast and good dynamic range in daylight, and the 2MP bokeh camera helps produce clean, natural-looking portrait blur. It sits a clear step below vivo’s flagship optics — the vivo X300 E pairs a Snapdragon 8 Gen 5 with Zeiss-tuned cameras — but for its class, the S2’s setup is well-rounded.
The standout feature is 4K video recording on BOTH the front and rear cameras. Most phones still cap the selfie camera at 1080p, so being able to record vlogs in 4K from either camera is a real content-creator advantage. The 32MP front camera captures detailed selfies with natural skin tones and a wide field of view, and Dual View Video lets you record from both cameras at once — perfect for reaction videos and interviews.
The Aura Light ring flash deserves a mention. Unlike a harsh conventional LED flash, it provides softer, more even illumination for low-light portraits, and you can adjust its brightness to match the scene. The camera app also includes Night Mode, Supermoon, Food Mode, Pro Mode, and a practical AI Erase 2.0 tool that removes unwanted objects from photos with a single tap.
There’s no telephoto or ultrawide lens here — just the main camera and a 2MP depth sensor. If you need optical zoom or wide-angle shots, look elsewhere. The S2 is built for portrait photography and content creation, not camera versatility.
Battery & Charging
This is the vivo S2’s biggest selling point. The 7,050mAh BlueVolt battery is genuinely enormous for a phone this slim, and vivo claims up to 33 hours of video playback, 43.7 hours of music, and 12.6 hours of Free Fire gaming on a single charge. Real-world usage will vary — I’d expect most users to get a full day and a half easily, with light users pushing close to two days.
vivo also says the battery retains at least 80% of its original capacity after 1,600 charge cycles, roughly six years of battery health. For someone who keeps a phone for the long haul, that’s a meaningful promise — the same kind of battery-first thinking I flagged in my Poco M8 Power review.
Charging is 44W FlashCharge, with the adapter included in the box. It’s not the fastest in its class — at this price, rivals like the Oppo A7 Pro Max push 80W — but it balances speed with battery longevity and thermal management. A cell this size takes well over an hour to top up from empty, so this is an overnight-charge phone rather than a quick-boost one. There’s also reverse wired charging for topping up accessories or a friend’s phone.
Software
The S2 runs OriginOS 6 based on Android 16, and it’s one of the cleaner Android skins around. The interface is polished, animations are fluid, and — refreshingly — there’s almost no bloatware. The pre-installed apps like Netflix, Facebook, Spotify, and Truecaller can all be removed if you don’t want them.
vivo’s software commitment is genuinely competitive: three years of Android OS upgrades and five years of security updates. For an upper mid-range phone, that long-term support significantly improves the value proposition if you plan to keep the device for several years.
OriginOS 6 is packed with AI features. Google Gemini is integrated system-wide, Circle to Search works straight from any screen, and there are tools like AI Creation for content generation, AI Transcript Assist for meeting notes, AI Captions for real-time subtitles, and a Smart Call Assistant for call transcription. Origin Island — vivo’s version of the Dynamic Island-style notification cutout — is a nice touch for glanceable alerts.
One genuinely useful addition is AI SuperLink, which automatically switches to the strongest Wi-Fi or cellular connection in weak-signal environments like elevators or underground parking. And Shake and Share transfers high-res photos and 4K videos between compatible devices without needing mobile data — handy for creators.

Should You Buy This?
Buy it if
- You want a phone that lasts — the 7,050mAh battery comfortably clears a full day and a half of heavy use, and the six-year battery health promise means it’ll still hold up years from now.
- You’re a content creator or vlogger who wants 4K recording from both cameras, Dual View Video, and Aura Light portraits in a phone under ₹40,000.
- You value durability in a stylish package — IP68/IP69 and MIL-STD-810H protection is rare at this price point.
- You’re tired of bloatware and want a clean Android experience with long update support.
Skip it if
- You’re a performance-first buyer — for the same money, chipsets like the Snapdragon 7 Gen 4 or Dimensity 8500 Ultra offer more raw power.
- You need camera versatility — no ultrawide or telephoto means you’re limited to the main lens.
- You’re outside India — the S2 is India-exclusive for now, with no official Philippine launch announced.
- You want the fastest charging possible — 44W is fine, but rivals push 66W-80W in the same bracket.
Final Verdict
The vivo S2 is a confident return for the S series. It’s not trying to win benchmark wars — it’s a phone built around design, battery endurance, durability, and content creation, and it executes those priorities well. The 7,050mAh battery in a 7.99mm body is genuinely impressive engineering, and the combination of IP69 durability, a beautiful 1.5K curved display, and 4K-capable front camera makes it a compelling all-rounder for its intended audience.
The compromises are real, though. LPDDR4X RAM, a plastic back, no ultrawide or telephoto, and 44W charging all feel like deliberate cost-cutting in a ₹39,999 phone that’s competing with more aggressively-spec’d rivals. Compared to the Redmi Note 17 Pro or the iQOO Z11, you’re paying a premium for the design and the vivo brand experience — and for many buyers, that’s exactly the point.
For the Philippines, the S2 is a tempting gray-market import candidate once it goes on sale — at roughly ₱25,600 for the base model, it lands in the same price territory as the battery-champion phones we’ve seen locally while matching their endurance. Just remember you’d be buying without official local warranty support, which matters when you’re trusting a 7,050mAh battery to your daily life.
Who is the vivo S2 for? Someone who wants a phone that looks and feels more expensive than it is, lasts two days on a charge, and won’t flinch in the rain. If that sounds like you, the seven-year wait was worth it. For everyone else, the S2 is a solid upper mid-ranger that knows exactly what it wants to be — and executes it honestly, even if the price demands a second look.
