Summary

Strengths

Weaknesses

- Proprietary magnetic charging adapter can be finicky if not aligned perfectly
- 4.3-inch screen shows fewer words per page than larger readers
- Stock firmware is basic and can feel sluggish compared to custom firmwares

Full research notes and sources
Battery life and charging
The 1100 mAh battery provides 14–21 days of typical use with the frontlight off. With the light on at moderate brightness, battery life drops but remains reasonable. Charging uses a magnetic pogo-pin adapter included in the box, with a red indicator while charging and white when fully charged. The proprietary connector requires careful alignment for reliable charging.
File formats and software
The X4 Pro supports EPUB, PDF, MOBI, and TXT files natively when sideloaded via microSD card. It does not support DRM-protected files, so users with large Kindle or Kobo libraries need to convert books or switch platforms. The stock firmware is simple but basic, and some owners find the UI sluggish compared to community firmwares.
The real advantage is the community firmware ecosystem. CrossPoint, Licorice, and SolarOS offer better EPUB handling, more fonts, additional layout options, and even turn the device into a general-purpose computer with SolarOS. This significantly improves usability for users willing to flash custom firmware.
Magnetic phone attachment
The integrated magnetic back lets the X4 Pro attach to MagSafe phones or use the included adhesive metal rings for non-MagSafe devices. This creates a grab-and-go reading experience that helps users avoid doomscrolling on their phones. The magnetic connection is strong enough to keep the reader attached during casual use.
Value and repairability
At $99, the X4 Pro offers strong value for minimalist readers who want portability, low-light reading, and open-format support. The device is more repairable than many sub-$100 readers, with XTEINK selling replacement parts including the magnetic charging adapter, screen protector, and adhesive metal rings.
For users who primarily read DRM-free files and value portability, the X4 Pro is compelling, especially during sales at $84–87.
