🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Revive your Nubia Z40 5G or Z40 Pro with this Li3947T44P8h906452 4800mAh replacement battery. Released in early 2022, the Nubia Z40 series was designed for users who demanded flagship performance without compromise, featuring a 6.67-inch 144Hz AMOLED display, Snapdragon 8 Gen 1 processor, and a 64MP triple-camera system with Sony IMX787 sensor. The 4800mAh battery combined with 80W fast charging provided exceptional endurance and rapid top-ups. After years of use, the original battery capacity has likely degraded significantly. This Li-ion Polymer battery restores the full 4800mAh capacity, bringing back the reliable all-day performance the Z40 series was designed for. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Designed for Flagship Performance and Endurance: The Nubia Z40 series was engineered for power users who need reliable performance throughout the day. The 4800mAh battery originally provided approximately a full day of heavy use. After years of daily charging cycles, the original battery’s capacity naturally decreases. Common indicators include: the device requiring multiple charges per day, unexpected shutdowns at 15-25% battery remaining, noticeably slower charging than when new, or visible battery swelling. This replacement restores the original battery life and charging speed, extending the useful life of the device. The Li3947T44P8h906452 battery is fully compatible with the phone’s 80W fast charging capability, allowing for quick power-ups when needed. Nubia’s MyOS is optimized for battery efficiency, and a fresh battery brings back the smooth, responsive experience the Z40 series was designed for.
Compatibility Note: Fits Nubia Z40 5G and Nubia Z40 Pro. Please confirm your battery model before ordering — Li3947T44P8h906452 is printed on your original battery. This battery is NOT compatible with Nubia Z40S Pro, Nubia Z50 series, Nubia Red Magic 6/7 series, or other Nubia models. The Z40 5G and Z40 Pro share the same battery design; using a different battery model may cause charging issues or incorrect battery reporting.

The Li3947T44P8h906452 4800mAh battery for Nubia Z40 5G has a typical capacity of 4800mAh (18.28Wh) and a rated voltage of 3.87V, with a charge limit of 4.45V. This Li3947T44P8h906452 3.87V 4800mAh Li-ion Polymer battery is built with grade A cells and is CE, RoHS, and UN38.3 certified. For Nubia Z40 5G battery life after replacement, expect approximately a full day of heavy use on a single charge. The Nubia Z40 5G 4800mAh battery performance provides excellent endurance for gaming, streaming, and multitasking. Charging the Nubia Z40 5G battery with the original 80W fast charger takes approximately 30 minutes to reach 50% capacity. The battery also supports the full fast charging capabilities of the Z40 series. For best performance, allow 2-3 full charge cycles after installation to calibrate the battery meter.

Professional Nubia Z40 5G battery installation is recommended. The Nubia Z40 5G and Z40 Pro have sealed glass backs with strong adhesive. To replace Nubia Z40 5G battery, the technician must heat the back cover to soften adhesive, carefully pry it open to avoid cracking the glass, disconnect the battery's small 2-pin connector, remove the old battery, and install the new Li3947T44P8h906452 battery before resealing. The 6.67-inch 144Hz AMOLED display is fragile, and improper prying can damage it. Third-party repair shops typically charge $20-35 for labor. For Nubia Z40 5G battery health maintenance: 1) Use only the original Nubia 80W charger and cable for optimal charging. 2) Keep battery level between 20% and 80% for daily use to maximize lifespan. 3) Avoid exposing the phone to high temperatures (above 40°C / 104°F), especially while charging. 4) For long-term storage (over 2 months), keep the battery at approximately 40-60% charge. 5) Perform a full calibration cycle after installation: drain the phone until it auto-shuts off, then charge uninterrupted to 100% using the original 80W charger. For Nubia Z40 5G battery care tips, stop using immediately if the battery shows any swelling.
