The Onyx Boox Note X5 Mini has a compact physical footprint, measuring 194 mm in height and 136.5 mm in width, with a slim 6.4 mm thickness and a total volume of 169.4784 cm³. It weighs 235 g, keeping it light enough for comfortable one-handed use. The device is not weather-sealed, so it offers no protection against splashes or moisture exposure.
The display is a 7.8″ self-lit e-paper touchscreen with a resolution of 1404 x 1872 px and a pixel density of 300 ppi, delivering sharp, detailed text rendering well-suited to reading. It includes an anti-reflection coating to reduce glare under various lighting conditions. The screen does not feature branded damage-resistant glass.
The device runs on an octa-core processor with a total clock speed of 8 x 2 GHz, paired with 4 GB of RAM to handle multitasking and app usage. It comes with 64 GB of internal storage for holding documents, books, and other files. There is no external memory slot, so the built-in storage cannot be expanded.
Wireless connectivity is handled through Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), alongside Bluetooth 5 for connecting compatible accessories and peripherals. A built-in browser is also included for web access. The device does not support cellular connectivity, NFC, or HDMI output.
The device is equipped with a 2300 mAh rechargeable battery that charges via USB Type-C, and it includes a battery level indicator to keep track of remaining charge. The battery is not removable, and the device does not support fast charging or wireless charging.
The device includes stereo speakers with text-to-speech support, a built-in dictionary, and HDR mode, while supporting 28 file types to accommodate a broad range of content. A child lock, accelerometer, and gyroscope are also on board, adding to its functional range. It does not have a 3.5 mm headset jack, GPS, compass, radio, or front camera.
On the software and privacy side, the device offers a notably broad feature set, including on-device machine learning, offline voice recognition, voice commands, Live Text, and split-screen multitasking. Users have access to dark mode, extra dim mode, dynamic theming, theme customization, widgets, customizable notifications, clipboard warnings, and full-page screenshots. Privacy controls cover location options, camera and microphone access management, and the ability to block app tracking, though cross-site tracking blocking, Mail Privacy Protection, and Wi-Fi password sharing are not supported. Additional capabilities include a media picker, notification permissions, device position tracking, sharing intents, Picture-in-Picture, panorama capture, slow-motion video recording, and the option to play content while downloading. The system supports multiple user accounts and is free and open source, while Quick Start, focus modes, app offloading, and battery health check are absent.
