The timing could not be more awkward for this phone. The Vivo S2 FE launches today with a 10,000mAh battery at a price expected to sit near the same Rs 39,999 this phone asks for. So this Vivo S2 review is really answering two questions: is the original S2 worth your money, and does the new FE make it irrelevant before you finish reading?
Short answer: the S2 was already a battery-first phone in a segment that has since gone battery-mad, and that is both its charm and its problem.
The two-day battery is not a marketing line
Start with the headline spec, because it is the one you will feel every day. A 7,050mAh battery inside an 8.1mm phone. A couple of years ago those two numbers refused to share a body. Silicon-carbon cells changed the maths, and Vivo was one of the first to cash in.
Reviewers who actually lived with the phone keep landing in the same place. Editorji squeezed close to two full days out of demanding daily use: heavy camera testing, GPS navigation, social scrolling, routine gaming. An hour of BGMI and Call of Duty: Mobile took just 9%. MensXP’s verdict used almost identical language: outstanding battery life without overheating. When three separate reviewers say the battery is the best thing about the phone, believe them.
Charging is the honest footnote: 44W with the brick in the box, a little over an hour and ten minutes for a full charge. Respectable for a cell this size, slow next to the 80W and 90W phones circling this price. Vivo bet on two-day endurance over fifteen-minute top-ups, which is the right call for most people.
One feature deserves its own mention: bypass charging, which routes power straight to the board while you game so the battery does not cook. It is a genuinely thoughtful touch that most brands reserve for flagships. Your battery ages slower, your hands stay cooler. Small things like this are how you tell a phone was designed by people who actually use phones.
Small aside: the battery wars of 2026 are genuinely absurd, and I love it. The Realme P4 packs 10,001mAh, the S2 FE reportedly matches it, and the S2’s 7,050mAh went from “ridiculous” to “fine, I guess” in about two months. Capacity inflation used to take years. Now it takes a product cycle. If you bought the S2 for the battery being special, the calendar has not been kind.
Vivo S2 review: the screen it charges you extra for
The 6.83-inch curved AMOLED is the second reason this phone exists. 1.5K resolution, 120Hz, 3,000 nits peak brightness. In plain language: sharp, smooth, and readable in harsh Indian sunlight without squinting. Reviewers consistently rate it among the best panels in the sub-Rs 40,000 band. MySmartPrice gave the display 8.7 out of 10, and in this price bracket, that kind of score usually costs more.
Curved screens divide people, and if you dislike them, nothing else on this phone will convert you.
The chip is where the Rs 39,999 ask gets awkward
Here is the honest paragraph. The Dimensity 7360 Turbo is fine. It is quick in daily use, it handles BGMI at respectable settings, it runs cool. It is also the thing every reviewer flagged as the phone’s ceiling. MySmartPrice scored performance 6.9 out of 10, the lowest of any category, and called the chip behind its rivals. The YouTube reviewers were blunter: the chip does not feel like a Rs 40,000 chip.
If raw performance matters to you, our OnePlus 15R review shows what flagship silicon feels like at a higher price, and our Realme P4 Pro vs Vivo V60e comparison shows what gaming-first hardware costs for ten thousand less. The S2 is not playing that game. It is playing the battery and design game, and the price tag is where the two games collide.
Cameras: one good lens, one decoration, one good idea
The camera system is a 50MP Sony IMX852 main sensor, a 2MP bokeh helper, and Vivo’s Aura Light ring. Let us be direct about the second camera: it is decoration. A one-camera phone with a passenger. The main sensor, though, is genuinely good. Clean daylight shots, solid portraits, dependable 4K video. The 32MP front camera handles selfies well. This is not a camera phone, but it is not a camera disappointment either, as long as your expectations stay in the “good main camera” lane.
The good idea is the Aura Light. A ring light built into the camera module that actually flatters portraits in bad lighting instead of nuking them with a harsh flash. Reviewers keep praising it, and for good reason: it is the rare camera gimmick that survives contact with real use. Wedding season portraits at night will look better on this phone than on most rivals. That is a narrow win, but it is a real one.
Built to survive, shipped with bloat
Durability is where the S2 quietly overdelivers. IP68 and IP69 ratings, MIL-STD-810H shock resistance, dual stereo speakers. This phone is sealed and tested like something costing considerably more. One monsoon season with a lesser phone teaches you the value of an IP69 rating fast.
Software is the mixed bag. OriginOS 6 on Android 16 is fluid and feature-rich, with three OS upgrades and five years of security patches. The bloatware is the tax Vivo charges for everything else being good: too many preloaded apps, too many notifications on day one. An hour of cleanup buys you a phone that will feel fine for years.
The plastic build is the other honest compromise. It looks premium and survives drops better than glass, but it does not feel premium in hand.
The verdict: buy it for endurance, skip it for speed
So, with conviction.
Buy the Vivo S2 if two-day battery life is your top priority and you want it wrapped in a slim, good-looking phone with a genuinely excellent display. Buy it if durability ratings matter to you, if you take night portraits, or if you keep phones for four years. At street prices below the Rs 39,999 sticker, which exist, this becomes a much easier recommendation.
Do not buy it if performance is your thing. Gamers, benchmark watchers, anyone who upgrades every two years chasing speed: the Dimensity 7360 Turbo and the older RAM and storage will frustrate you, and cheaper phones now beat it on silicon. Do not buy it if you need a versatile camera system either. One good main lens does not make a camera phone.
And the FE question, since it launches today. If the S2 FE lands with its 10,000mAh battery anywhere near this price, the original S2’s battery argument gets eaten by its own sibling. That is the cruel maths of the battery wars: today’s hero is tomorrow’s warm-up act. Buy the S2 for what it is right now, a dependable two-day phone with a great screen, and buy it on a discount. Or wait a week and see what the FE actually costs. Either way, buy on the price, not the launch sticker.
