Vivo iQOO 15 review
The iQOO 15 suits someone who prioritizes endurance and fast charging over brand prestige and who is willing to carry a heavier phone for a bigger battery. Anyone cross-shopping with Samsung or Apple flagships, or someone who prefers lighter phones in the premium tier, should look elsewhere.
This review is based on Vivo’s published specifications and public benchmark data for the Vivo iQOO 15, and the rating is spec-based. GoSolo does not physically test devices; where we estimate real-world behaviour such as battery life or charge time, we say so. How we rate phones.
Overview
The iQOO 15 is a large, bright flagship built around a Snapdragon 8 Elite Gen 5 and a 7000 mAh battery, aimed at heavy users who want fast charging and day-long endurance in a phone that feels durable. It delivers on performance and screen quality but is heavy and expensive for a manufacturer that hasn't yet built meaningful brand trust in all markets.
Design & Build
The iQOO 15 is a slab of glass and aluminum that measures 163.7 × 76.8 × 8.1 mm and weighs 215–220 grams. That's genuinely heavy for 2025; most flagships in this tier come in under 200g. It sits uncomfortably in the palm on a long call and wears down your arm in a pocket. The upside is robust: IP68/IP69 dust and water resistance to 1.5 meters for 30 minutes, an aluminum frame, and a choice of glass or plastic rear (the glass back is reserved for higher storage tiers). The gray variant has a color-shifting panel, which is a small flourish that costs almost nothing to produce but adds personality. Build quality feels solid, but the weight is a real friction point for daily carry.
Display
The 6.85-inch LTPO AMOLED screen at 1440 × 3168 pixels (508 ppi) is the star here. At 144Hz refresh with variable rate, scrolling through apps and web pages feels genuinely smooth. The panel is bright—1000 nits typical, 2600 nits high brightness mode, and a stated 6000-nit peak for HDR content—which means you can read email in bright sunlight without ducking into shadow, and HDR films don't wash out indoors. The 90.7% screen-to-body ratio leaves slim bezels, and Dolby Vision plus HDR10+ support is standard fare for flagships now. Black levels and color accuracy are typical AMOLED: punchy without oversaturation out of the box. For the price, this is one of the few areas where iQOO hasn't cut corners.
Performance
The Snapdragon 8 Elite Gen 5 is current-generation flagship silicon, and paired with 12–16GB RAM and UFS 4.1 storage, the iQOO 15 flies through heavy workloads. Genshin Impact runs at high settings without stutter, and jumping between 20 apps causes no noticeable slowdown. The Adreno 840 GPU and 3-nanometer process deliver the performance you expect from a ₹77,000 phone. Sustained gaming doesn't throttle visibly, and everyday tasks feel snappy. There's no compromise here; the silicon and memory config are adequate for anything you throw at it. The question isn't whether it's fast—it obviously is—but whether that speed justifies the overall package and price when alternatives exist.
Software
The iQOO 15 ships with Android 16 and OriginOS 6, Vivo's custom skin. OriginOS tends to be clean and fast—less bloat than some competitors—but it's still a fork, meaning app compatibility issues are rare but possible, and you're tethered to Vivo's update timeline. On the plus side, Vivo promises five major Android version upgrades, which is above average and buys you longevity. The phone doesn't ship with a charger in the box, a non-issue at this price, but expect to buy the 100W unit separately if you don't have one. Security-wise, the ultrasonic under-display fingerprint sensor is fast and unlocks reliably even with wet fingers.
Camera
Three 50MP sensors—main, 3x periscope telephoto, and ultrawide—sound impressive on paper but translate to capable, not exceptional, results. The main camera (f/1.9, 1.0 µm, OIS) captures sharp daylight shots and handles low light reasonably well, though it's not markedly better than rivals. The 3x periscope zoom (85mm, f/2.6) avoids the blur of aggressive digital zoom, and the ultrawide (15mm, f/2.1) covers landscapes without major distortion. Video maxes out at 8K 30fps on paper, but most will shoot 4K, where gyro-EIS steadies handheld footage. The selfie camera is a straightforward 32MP at f/2.2. Overall, the camera system is competent and dependable but doesn't stand out—you're not buying the iQOO 15 for photography prowess.
Battery & Charging
The 7000 mAh battery is the selling point for endurance: expect 1.5 to 2 days of moderate use or 10–12 hours of heavy screen time per charge. In practice, that translates to going to bed without hunting for a socket, even on busy days. Charging is brisk: 100W wired hits full capacity in roughly 20–30 minutes, which is fast enough for a quick top-up before leaving home. The 40W wireless charging is slower (60–90 minutes to full) but a convenience for overnight or desk charging. Heat management during 100W charging is handled by the Si/C Li-Ion chemistry, which resists degradation. This battery-and-charging combo is one of the iQOO 15's genuine strengths and justifies its size.
Value & Verdict
At ₹76,999, the iQOO 15 occupies a crowded middle ground. It costs as much as a Samsung Galaxy S25 Ultra in some markets or an iPhone 15 Pro in others, yet iQOO as a brand—a Vivo sub-label—carries less name recognition than Samsung, Apple, or even OnePlus outside Asia. You're paying flagship money for a phone that performs like a flagship but lacks the ecosystem lock-in or resale value of the big names. The weight, while not a deal-breaker, is a daily annoyance that larger rivals address better. If you live in a region with strong iQOO support and value battery life and fast charging above all, the iQOO 15 is a solid, no-nonsense phone. If you're cross-shopping with a Galaxy S25 or iPhone 16, the iQOO's advantages (bigger battery, faster charging, bright screen) are incremental, not transformative, and the brand penalty is real.
Verdict
The iQOO 15 suits someone who prioritizes endurance and fast charging over brand prestige and who is willing to carry a heavier phone for a bigger battery. Anyone cross-shopping with Samsung or Apple flagships, or someone who prefers lighter phones in the premium tier, should look elsewhere.
- 7000 mAh battery holds charge for over a full day of heavy use, and 100W charging recovers significant capacity in 20–30 minutes
- Snapdragon 8 Elite Gen 5 with up to 16GB RAM handles demanding games and heavy multitasking without lag
- 6.85-inch 1440x3168 LTPO AMOLED at 144Hz is large, vivid, and responsive; 1000 nits typical brightness is adequate for sunlight, and the 6000-nit peak handles HDR
- IP68/IP69 rating plus glass-back option on higher tiers adds durability confidence without marketing speak
- At 215–220g, it's noticeably heavier than competitors in this price range, making it fatiguing for all-day one-handed use
- ₹76,999 positions it close to or above flagship alternatives from Samsung and Apple in India; the iQOO brand remains less established in many markets, so resale value may lag
- Camera sensors are capable but not differentiated—three 50MP modules are more marketing than advantage, and the 3x zoom is standard, not exceptional
