The ASUS ZenBook 13 UX325JA is a compact 13.3-inch ultrabook, originally launched in 2020, equipped with the C41N1904-1 battery, which is the genuine replacement battery for this model. The device features 10th-generation Intel Core i5-1035G1 or i7-1065G7 processors, up to 16GB LPDDR4X-3200 RAM, and PCIe NVMe SSD storage up to 1TB. The 13.3-inch Full HD (1920×1080) IPS display boasts a 88% screen-to-body ratio and brightness of up to 450 nits. Connectivity includes 2× Thunderbolt 3 USB-C ports, 1× USB 3.2 Type-A, HDMI, and a microSD card reader. The laptop weighs approximately 1.07–1.15kg and measures just 1.39cm thin.

The UX325JA delivers smooth everyday performance for office tasks, web browsing, and media consumption. The lightweight all-metal construction and compact size make it highly portable for students, business travelers, and remote workers. The backlit chiclet keyboard with 1.4mm key travel is comfortable for extended typing, while the innovative NumberPad 2.0 integrates a numeric keypad into the touchpad. The IR webcam supports Windows Hello for secure facial recognition login. Battery life is exceptional thanks to the 67Wh battery, rated for up to 22 hours of video playback under ideal test conditions. In real-world office workloads, users can expect around 11 hours of mixed usage. The 65W USB-C power adapter supports fast charging, replenishing up to 60% in approximately 49 minutes.

The C41N1904-1 is a 4-cell lithium-polymer battery with a capacity of 4347mAh and 67Wh. To maximize its lifespan, use ASUS’s built-in battery health charging feature in MyASUS to set a charging limit of 60% or 80% for long-term AC use. Avoid exposing the laptop to extreme temperatures, and store the device at approximately 50% charge if not in use for extended periods. After 500 recharge cycles, battery performance will naturally decline. Periodic calibration—allowing a full discharge followed by a full recharge—is recommended every few months.

The UX325JA’s greatest strength lies in its exceptional battery life, driven by the high-density 67Wh C41N1904-1 battery and Intel Project Athena certification for instant wake and responsiveness. The ultra-lightweight design (just 1.07kg) combined with military-grade MIL-STD-810G durability ensures reliability on the go. Two Thunderbolt 3 ports provide up to 40Gbps data transfer and support for dual 4K displays. The display options—either a 450-nit 100% sRGB IPS panel or a stunning OLED variant—offer excellent image quality for the price point. For its launch price bracket (around $900–$1,300 depending on configuration), the ZenBook 13 delivers outstanding value as a premium ultraportable.

The UX325JA has several notable limitations. Most critically, it lacks a dedicated 3.5mm headphone jack—an adapter is included in the box, but this remains an inconvenience for wired audio users. The integrated Intel UHD or Iris Plus Graphics are not suitable for gaming or 3D rendering. The chassis, while lightweight, is prone to collecting fingerprints and may creak under pressure, feeling less premium than some competitors. RAM is soldered onboard and cannot be upgraded after purchase, so buyers must choose their configuration carefully. The speakers are mediocre, and port selection, while decent, lacks a full-size RJ-45 Ethernet port. Some users also report accidental NumberPad activation during regular typing.

The ASUS ZenBook 13 UX325JA, powered by the C41N1904-1 battery, is an ultraportable laptop tailored for mobile professionals, students, and frequent travelers who prioritize battery life and portability above all else. It excels as a daily driver for productivity work, content consumption, and remote collaboration, delivering exceptional endurance in a slim, lightweight chassis. However, creative professionals, gamers, or users requiring upgradeable components should look elsewhere. For its target audience—those who need a reliable, all-day companion that slips easily into any bag—the UX325JA remains a compelling choice in the used or refurbished market as of 2026.
