The Unihertz Jelly Max has a compact footprint, measuring 128.7 mm tall, 62.7 mm wide, and 16.3 mm thick, with a total volume of around 131.53 cm³ and a weight of 180 g. It is neither a rugged nor a folding device, and it offers no water resistance rating.

The Unihertz Jelly Max features a 5.05-inch IPS LCD touchscreen with a resolution of 720 x 1520 pixels and a pixel density of 333 ppi, running at a 60Hz refresh rate.

The Unihertz Jelly Max is powered by the MediaTek Dimensity 7300, a 4 nm chipset built with 6,200 million transistors and an octa-core CPU running at 4 x 2.5 GHz and 4 x 2 GHz using big.LITTLE architecture with HMP support. It comes with 12 GB of LPDDR5 RAM at 6400 MHz — expandable up to 16 GB — alongside 256 GB of internal storage. Graphics are handled by the Mali G615 MC2 GPU clocked at 1047 MHz, supporting DirectX 12 and a single display output. The chipset includes integrated LTE and integrated graphics, supports 64-bit processing across 8 threads, and scores 1026 in Geekbench 6 single-core and 2932 in multi-core testing.

The Unihertz Jelly Max sports a dual rear camera system with a 100 MP and an 8 MP lens, both using a CMOS sensor without back-illumination. Autofocus options include phase-detection and touch autofocus as well as continuous autofocus during video recording, though laser autofocus is absent. Manual controls cover exposure, ISO, focus, and white balance, while burst mode, HDR, slow-motion video, and in-camera panoramas are all supported; however, there is no optical zoom, no RAW capture, no timelapse, and no manual shutter speed control. A single LED flash is present on the rear, but there is no dual-tone or RGB flash. On the front, a 32 MP single-lens camera handles selfies without a dedicated flash or an under-display placement, and video recording does not support HDR10, Dolby Vision, or 3D capture.

The Unihertz Jelly Max runs Android 14 and covers a broad range of software features. On the privacy side, it includes clipboard warnings, location privacy controls, and camera/microphone access management, along with the ability to block app tracking; however, Mail Privacy Protection and cross-site tracking blocking are not available. Customization options include theme customization, dynamic theming, dark mode, extra dim mode, widgets, and customizable notifications, though focus modes are not supported. Productivity features include split-screen multitasking, picture-in-picture, full-page screenshots, a media picker, sharing intents, Live Text, and the ability to play games while they download. The device also supports offline voice recognition and voice commands, on-device machine learning, multi-user accounts, child lock, battery health check, and phone tracking. Wi-Fi password sharing, app offloading, Quick Start, and desktop PC mode are not included, and OS updates are not delivered directly from the vendor.

The Unihertz Jelly Max is equipped with a 4000 mAh rechargeable battery that supports fast charging, and a charger is included in the box. A battery level indicator is present for at-a-glance monitoring. The battery is not removable, and wireless charging is not supported.

The Unihertz Jelly Max has a notably limited audio feature set. It lacks a 3.5 mm headphone jack and stereo speakers, and no radio is present. On the wireless audio side, none of the high-quality Bluetooth codec options are supported, including aptX, aptX HD, aptX Adaptive, aptX Lossless, and LDAC.

The Unihertz Jelly Max offers a solid connectivity lineup, including 5G support, Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), Bluetooth 5.3, and NFC, with download and upload speeds reaching up to 3270 MBits/s. It accommodates two SIM cards and includes an external memory slot for storage expansion. The USB Type-C port runs on USB 2.0, and there is no HDMI output. For navigation and sensing, the device includes GPS with Galileo support, a compass, gyroscope, and accelerometer, while a barometer, infrared sensor, heart rate monitor, and motion or optical tracking are all absent. Security is handled by a fingerprint scanner, with no 3D facial recognition or iris scanner on board. Emergency SOS via satellite, crash detection, ANT+, DLNA certification, a built-in projector, and a stylus are not part of the feature set.

The Unihertz Jelly Max includes a video light, which can be used during video recording or as a torch. The display is flat rather than curved, and it uses neither sapphire glass nor an e-paper panel.
