The Vivo iQOO 15 Ultra has a fixed, non-folding body measuring 163.7 x 76.8 x 8.7 mm with a volume of 109.38 cm³ and a weight of 227 g. It carries an IP68 ingress protection rating, certifying it as waterproof to a depth of 1.5 m, though it does not feature a rugged build designation.

The Vivo iQOO 15 Ultra features a 6.85″ OLED/AMOLED touchscreen with a 1440 x 3168 px resolution at 508 ppi and a 144Hz refresh rate, delivering a sharp and fluid visual experience. Typical brightness is rated at 1000 nits, and the display supports both HDR10 and HDR10+, while Dolby Vision is not supported. Always-On Display is available, but there is no secondary screen, and the panel does not use branded damage-resistant glass.

The Vivo iQOO 15 Ultra is powered by the Qualcomm Snapdragon 8 Elite Gen 5, a 3 nm chipset running 8 threads across two clusters clocked at 2 x 4.6 GHz and 6 x 3.62 GHz, with a TDP of 8.2W and support for big.LITTLE and HMP scheduling. It pairs 16GB of DDR5 RAM at 5300 MHz — expandable up to 24GB — with 1024GB of internal storage, delivering a maximum memory bandwidth of 85.1 GB/s across two channels, alongside L1, L2, and L3 caches of 192 KB, 12 MB, and 8 MB respectively. The integrated Adreno 830 GPU runs at 1200 MHz, drives up to two displays, and offers 1536 shading units with support for DirectX 12, OpenGL 3.2, OpenGL ES 3.2, and OpenCL 3. The chipset also includes integrated LTE, TrustZone security, ECC memory support, and 64-bit processing, while benchmark results stand at 4,517,353 on AnTuTu, 10,059 on Geekbench 6 multi-core, and 3,234 on single-core.

The Vivo iQOO 15 Ultra sports a triple rear camera system with three 50 MP CMOS sensors at apertures of f/1.9, f/2.1, and f/2.7, covering a focal range from 15 mm to 85 mm with 3x optical zoom and built-in optical image stabilization. Autofocus options include phase-detection and touch autofocus for photos as well as continuous autofocus during video recording, though laser autofocus is absent. Video capture reaches up to 4320 x 30 fps, with slow-motion recording supported, while HDR10 recording and Dolby Vision recording are not available. The rear flash uses two LEDs but is neither dual-tone nor RGB. Manual controls cover exposure, ISO, focus, and white balance, though manual shutter speed is not provided, and the system supports burst mode, timelapse, and in-camera panoramas but not 360° panoramas or RAW shooting. On the front, a single 32 MP camera with an f/2.2 aperture handles selfies — it is a single-lens setup without an under-display placement or a dedicated flash.

The Vivo iQOO 15 Ultra runs Android 16, an open-source platform that supports multi-user accounts, split-screen multitasking, Picture-in-Picture, widgets, and the ability to play games while they are still downloading. Privacy features include clipboard warnings, location privacy options, camera and microphone access controls, and app tracking blocking, though cross-site tracking blocking and Mail Privacy Protection are absent. The interface offers theme customization, dynamic theming, dark mode, and an extra dim mode, while productivity is aided by full-page screenshots, Live Text, a media picker, customizable notifications, sharing intents, and a child lock. On-device machine learning, offline voice recognition, and voice commands are all supported, and the system includes phone tracking and a battery health check tool. Wi-Fi password sharing, focus modes, Quick Start, and the ability to function as a PC are not available, and direct OS updates from the vendor are not provided.

The Vivo iQOO 15 Ultra houses a 7400 mAh rechargeable, non-removable battery with a built-in level indicator. It supports fast wired charging at 100W and wireless charging at 40W, with a charger included in the box, though reverse wireless charging is not available.

The Vivo iQOO 15 Ultra includes stereo speakers and supports aptX HD and aptX Adaptive Bluetooth audio codecs, while aptX, aptX Lossless, and LDAC are not available. There is no 3.5 mm headphone jack and no built-in radio.

The Vivo iQOO 15 Ultra supports 5G cellular connectivity and accommodates two SIM cards, with download and upload speeds reaching 10,000 Mbits/s and 3,500 Mbits/s respectively. Wi-Fi coverage spans Wi-Fi 4, 5, 6, and 7, complemented by Bluetooth 5.4 and NFC, while DLNA certification and ANT+ support are absent. The USB Type-C port operates at USB 3.2, though there is no HDMI output and no external memory slot. Sensors on board include a fingerprint scanner, gyroscope, accelerometer, compass, GPS with Galileo support, and an infrared sensor, whereas a barometer, heart rate monitor, iris scanner, and 3D facial recognition are not present. Crash detection, emergency SOS via satellite, motion tracking, optical tracking, and a built-in projector are likewise not featured, and no stylus is included.

The Vivo iQOO 15 Ultra includes a video light, while its display is flat rather than curved and uses neither sapphire glass nor an e-paper panel.
