The Asus Zenfone 12 Ultra measures 163.8 mm tall, 77 mm wide, and 8.9 mm thick, with a total volume of 112.25 cm³ and a weight of 220 g. It carries an IP68 ingress protection rating, making it fully waterproof against dust and water immersion. The device does not feature a rugged build and is not a folding design.

The display is a 6.78″ OLED/AMOLED touchscreen with a resolution of 1080 x 2400 px and a pixel density of 388 ppi, running at a 144Hz refresh rate for smooth on-screen motion. Typical brightness reaches 1600 nits, and the panel supports HDR10, though HDR10+ and Dolby Vision are not supported. It is protected by Gorilla Glass Victus 2 and includes an Always-On Display mode, while there is no secondary screen present.

The device is powered by the Qualcomm Snapdragon 8 Elite chipset, built on a 3 nm process with an 8-thread CPU configuration running at 2 x 4.32 GHz and 6 x 3.53 GHz using big.LITTLE and HMP technologies, and a TDP of 8.2W. Graphics are handled by the Adreno 830 GPU clocked at 1100 MHz with 1536 shading units, supporting DirectX 12, OpenGL 3.2, OpenGL ES 3.2, and OpenCL 3, with up to 2 displays. The chipset pairs with 16 GB of DDR5 RAM at 5300 MHz across 2 memory channels, offering a maximum memory bandwidth of 85.1 GB/s and support for up to 24 GB, alongside 512 GB of internal storage. Cache is structured as 192 KB L1, 12 MB L2, and 8 MB L3, and the platform includes integrated LTE, TrustZone security, ECC memory support, multithreading, and 64-bit operation. Benchmark results place the device at an AnTuTu score of 2,850,000, with Geekbench 6 scores of 3,234 single-core and 10,059 multi-core.

The rear camera system uses three lenses — a 50 MP (f/1.9), 32 MP (f/2.4), and 13 MP (f/2.2) — with a CMOS sensor, optical image stabilization, and 3x optical zoom. Autofocus options include phase-detection and touch AF for photos, as well as continuous autofocus during video, though laser autofocus is absent. Video capture reaches up to 4320 x 24 fps with HDR10 recording and slow-motion support, while Dolby Vision recording and 3D capture are not available. Manual controls cover exposure, ISO, focus, and white balance, but manual shutter speed is not included; the camera also supports RAW capture, burst mode, panorama, and timelapse. Flash is provided by a single dual-tone LED unit, with no RGB flash and no front-facing flash. The 32 MP front camera sits at f/2.5 and is a single-lens setup positioned above the display, without an under-display placement, and HDR mode is available across the system.

The device runs Android 15 and includes a broad set of privacy controls, covering clipboard warnings, location privacy options, and camera/microphone access management, though Mail Privacy Protection and cross-site tracking blocking are not present. App tracking can be blocked, and on-device machine learning is supported. The interface offers theme customization, dynamic theming, dark mode, and an extra dim mode, while focus modes and Quick Start are not available. Productivity features include split-screen multitasking, Picture-in-Picture, full-page screenshots, a media picker, sharing intents, customizable notifications, Live Text, and the ability to play games while they download. Privacy and usability are further supported by a child lock, multi-user support, widgets, app offloading, battery health check, offline voice recognition, voice commands, and device tracking, though Wi-Fi password sharing and PC mode are not included. OS updates are not delivered directly from the vendor, and the platform is free and open source.

The Zenfone 12 Ultra houses a 5500 mAh rechargeable battery with a built-in level indicator, and a charger is included in the box. Wired fast charging is supported at 65W, while wireless charging operates at 15W; however, reverse wireless charging is not available. The battery is not removable.

Audio output is handled by stereo speakers, and a 3.5 mm headphone jack is present for wired connections. Bluetooth audio is well covered, with support for aptX, aptX HD, aptX Adaptive, and aptX Lossless, though LDAC is not supported. The device uses two microphones and does not include an FM radio.

Wireless connectivity covers 5G cellular, Wi-Fi 7 (802.11be) alongside Wi-Fi 4, 5, 6, and 6E, Bluetooth 5.4, and NFC, while the device accepts two physical SIM cards plus one eSIM. Download speeds reach up to 10,000 Mbits/s and upload up to 3,500 Mbits/s, and a USB Type-C port is provided, though there is no HDMI output and no external memory slot. Sensors on board include a fingerprint scanner, GPS with Galileo support, gyroscope, accelerometer, and compass, while a barometer, heart rate monitor, infrared sensor, and ANT+ are all absent. Security biometrics are limited to the fingerprint scanner, as 3D facial recognition and an iris scanner are not present. Satellite SOS, crash detection, DLNA certification, motion tracking, optical tracking, and a built-in projector are likewise not featured, and no stylus is included.

The device includes a video light for recording in low-light conditions. The display is flat rather than curved and uses neither sapphire glass nor e-paper technology.
