🔋 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.

Restore the flagship power of your Nubia Z50 Ultra with this Li3949T44P8h806756 5000mAh replacement battery. Released in March 2023, the Nubia Z50 Ultra features a 6.8-inch AMOLED display, Qualcomm Snapdragon 8 Gen 2 processor, and advanced camera capabilities. The 5000mAh battery combined with 80W fast charging provides excellent all-day endurance and rapid top-ups. After years of daily charging cycles, the original battery capacity naturally degrades. This Li-ion Polymer battery restores the full 5000mAh capacity, bringing back the reliable all-day performance this flagship device 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 Fast Charging: The Nubia Z50 Ultra is built for users who demand premium performance and long battery life. The 5000mAh battery originally provided approximately a full day of heavy use, with 80W fast charging delivering a full charge in about 35-40 minutes. After years of charging cycles, the original battery’s capacity drops significantly. Common symptoms include: the device requiring multiple charges per day, unexpected shutdowns at 15-25% battery remaining, slower charging than when new, or visible battery swelling. This replacement restores the original battery life and fast charging capability, extending the useful life of the device without the cost of a new flagship phone. The Li3949T44P8h806756 battery is fully compatible with the phone’s 80W fast charging technology, ensuring quick and efficient power delivery.
Compatibility Note: Fits Nubia Z50 Ultra (NX712J) only. Please confirm your battery model before ordering — Li3949T44P8h806756 is printed on your original battery. This battery is NOT compatible with Nubia Z50, Nubia Z50S Pro, Nubia Z60 Ultra, Nubia Red Magic series, or other Nubia models. The NX712J is the standard Nubia Z50 Ultra model; using a different battery model may cause charging issues or incorrect battery reporting.

The Nubia Z50 Ultra 5000mAh battery performance provides excellent endurance for 5G connectivity, gaming, photography, and multitasking. Charging the Nubia Z50 Ultra battery with the original 80W charger takes approximately 35-40 minutes for a full charge.

Professional Nubia Z50 Ultra battery installation is recommended. The Nubia Z50 Ultra has a sealed glass back with strong adhesive. To replace Nubia Z50 Ultra battery NX712J, 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 Li3949T44P8h806756 battery before resealing. The 6.8-inch AMOLED display is fragile, and improper prying can damage it. Third-party repair shops typically charge $20-35 for labor. For Nubia Z50 Ultra 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 Z50 Ultra battery care tips, stop using immediately if the battery shows any swelling.
