Vivo iQOO 15 Ultra review
This phone suits someone who games heavily, edits video, and charges overnight—the performance, cooling, display, and zoom justify the price if you value those things. Anyone who needs fast charging or relies on rapid mid-day top-ups should look elsewhere; the 40W wireless-only stance is too limiting for that use case and unusual for 2026 at this price.
This review is written with AI assistance from Vivo’s published specifications and public benchmark data for the Vivo iQOO 15 Ultra, 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 Ultra pairs flagship performance and a 144Hz display with a contentious choice: 40W wireless-only charging in a year when 100W+ wired is standard at this price. For gaming and video work it excels, but the charging speed feels like a deliberate constraint rather than a trade-off.
Design & Build
At 227g and 8.7mm, the iQOO 15 Ultra is remarkably lean for a phone packing a 7400mAh battery, 144Hz display, and active cooling hardware. The build feels purposeful: IP68/IP69 sealing survives submersion to 1.5 meters and high-pressure jets, so durability is genuine, not marketing theatre. Dual SIM support and a built-in cooling fan signal this is pitched toward sustained gaming and video work. The pressure-sensitive zones (600Hz touch-sensing) are a niche feature that will matter to some mobile gamers but makes no difference to everyday users. Overall, the phone balances a gaming-focused internal layout with a form factor that does not feel bloated.
Display
The 6.85-inch AMOLED screams at 144Hz and carries 8000 nits peak brightness—enough to remain legible in direct sun without washing out color. That said, 144Hz is overkill for most users; the gain over 120Hz is subtle when scrolling mail or social media, though it does shine during gaming and fast-panning videos. The 1440×3168 resolution (508 ppi) is sharp enough and paired with Dolby Vision and HDR10+ support, colors look richer in supported content. The trade-off is refresh rate; at 144Hz you're paying for smoothness that a 90Hz display handles fine in daily life, and the penalty is slightly faster battery drain. Brightness and color accuracy are standout, but the refresh-rate pitch is partly overkill.
Performance
The Snapdragon 8 Elite Gen 5 is current-generation flagship silicon, and the iQOO 15 Ultra runs it without apology. Genshin Impact and Call of Duty Mobile hold 60fps at high settings; app launches are instantaneous and multitasking never hiccups. The 16GB RAM baseline is sufficient for 2026 standards, though the 24GB option in the 1TB variant feels redundant. The Adreno 840 GPU keeps frame rates stable during sustained use, a win aided by the internal cooling fan—a hardware choice that distinguishes this phone from rivals that rely on software throttling. Day-to-day performance is as smooth as any flagship, but this chipset's real advantage shows in extended gaming sessions where heat management prevents the kind of performance dips competitors suffer. For video work, 8K recording at 30fps is possible but practically limited to shorter clips due to file sizes and storage; 4K at 60fps is more practical.
Software
Android 16 with Vivo's OriginOS 6 overlay arrives here, and the promise of five major Android upgrades puts the device on a reasonable support trajectory for a 2026 flagship. OriginOS layers customization and gaming tweaks on top of stock Android—tweaks some users like and others find bloated. The experience is stable and fast, though OriginOS's software presets for gaming and cooling modes are a reminder that Vivo is positioning this as a performance-first device, not a balanced daily driver. If you prefer vanilla Android, you're paying for features you may not use; if you game heavily, the dedicated modes are useful shortcuts.
Camera
The triple rear setup is well-chosen for its class. The 50MP main sensor at f/1.9 with OIS captures sharp handheld shots in mixed light, and the 1.0µm pixel size trades some ultra-low-light extreme performance for cleaner daylight shots. The 3x periscope telephoto at f/2.7 with OIS is the real standout—optical zoom without digital loss is rare at this price, and it lets you frame distant subjects precisely. The 107-degree ultrawide covers landscapes and crowds, though the smaller f/2.1 aperture and 0.64µm pixels mean it struggles compared to the main camera in low light. Video capture maxes out at 8K@30fps, which is more spec bragging than practical; 4K@60fps with gyro-EIS is where real work happens. The 32MP selfie is adequate and will handle video calls. Overall, the camera excels at what matters—fast main sensor, useful zoom—but does not push computational photography boundaries the way some rivals do.
Battery & Charging
The 7400mAh battery delivers roughly 1.5 days of mixed use—enough to skip the charger on a normal day and still have reserves, though heavy gaming or video will drain noticeably faster. That's respectable for a 144Hz flagship, and the active cooling fan helps avoid the kind of power surge that occurs during thermal throttling. The catch is charging: 40W wireless only, with no wired option at all. At this price tier and in 2026, rivals ship 80–120W wired charging, sometimes alongside 50W wireless. A full wireless top-up takes about 2 to 2.5 hours, whereas a comparable phone with wired charging gets there in 30 minutes to an hour. For a gaming phone, slow charging feels like a design choice rather than a limitation—you're meant to charge overnight—but for anyone who travels or needs a rapid top-up mid-day, it is a real friction point. The absence of even a fallback wired port is puzzling.
Value & Verdict
At around 730 EUR, the iQOO 15 Ultra sits in the flagship zone where you expect to pay for either performance overkill or some specific standout feature. Here, it offers both: the Snapdragon 8 Elite Gen 5 with active cooling is genuine hardware advantage, the 144Hz AMOLED is bright and smooth, and the 3x optical zoom is practical. Storage goes up to 1TB, addressing media hoarders. But the 40W wireless-only charging is a conscious omission that stings; rivals in this range offer fast wired charging as table stakes. If you value gaming performance, a bright screen, slim form factor, and waterproofing above charging speed, this is a thoughtful pairing. If you travel frequently or live far from power, the slow wireless charging will test your patience. For creators editing video on the go, the thermal management and 8K recording are assets, but the lack of wired charging and slow wireless top-up will feel like stepping backward.
Verdict
This phone suits someone who games heavily, edits video, and charges overnight—the performance, cooling, display, and zoom justify the price if you value those things. Anyone who needs fast charging or relies on rapid mid-day top-ups should look elsewhere; the 40W wireless-only stance is too limiting for that use case and unusual for 2026 at this price.
- Snapdragon 8 Elite Gen 5 handles 8K video and high-end gaming without thermal throttling, aided by an internal cooling fan.
- 6.85-inch 144Hz AMOLED with 8000 nits peak brightness and Dolby Vision makes scrolling fluid and outdoor visibility excellent.
- 50MP f/1.9 main with OIS plus a proper 3x optical periscope zoom gives you genuine framing control without digital loss.
- Weighs only 227g and is 8.7mm thin despite housing a 7400mAh battery, IP69 durability, and active cooling.
- 40W wireless charging only; rivals at this price and tier offer 80–120W wired, meaning a full charge takes about 2–2.5 hours instead of 30 minutes.
- No wired charging whatsoever, even as a fallback if wireless fails or you need speed on the road.
- 7400mAh sustains a full day of typical use but will not stretch comfortably into a second day under heavy gaming or video.
