Restore the flagship performance of your Nubia Z30 Pro with this Li7719T89P8h826559 replacement battery. Compatible with Nubia Z30 Pro (model NX667J), this dual‑cell Li-Polymer battery uses a series design — two 2100mAh cells connected in series — to achieve a combined output of 7.74V, delivering the factory‑rated equivalent 4200mAh capacity. The Nubia Z30 Pro was released in May 2021 featuring a 6.67-inch 144Hz AMOLED display, Qualcomm Snapdragon 888 processor, and supports 120W Neo Charge — officially capable of charging from 0% to 100% in just 15 minutes using the original 120W GaN charger. For reference, third‑party retailers sell this battery for approximately $25 to $40.
Built with Grade A Li-Polymer cells and multi‑layer safety protection against overcharge, over‑discharge, short circuit, and overcurrent. CE, RoHS, and UN38.3 certified for safe transport and use. The device supports 120W Neo Charge — when paired with the original Nubia 120W GaN charger (120W maximum output, also supports 65W PD output), the 4200mAh battery can be charged from 0% to 100% in approximately 15 minutes (officially tested). Professional installation is strongly recommended as the battery is not user‑replaceable — the phone has a sealed back cover with strong adhesive.
Compatibility Note: Please power down your device and check your original battery label before ordering. This battery is compatible with Nubia Z30 Pro (NX667J) only — NOT compatible with ZTE Axon series or other Nubia models. The battery is not user‑replaceable — professional installation is strongly recommended as the phone has a sealed design with strong adhesive. The phone has no official IP water resistance rating, so water seal maintenance is not a concern after replacement.
Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3‑5 full charge cycles to reach optimal capacity. For best 120W Neo Charge performance, use the original Nubia 120W GaN charger that came with your phone. If you don’t use the device for a long time, store it in a dry and cool place and charge it fully once every three months. If you notice swelling or overheating, stop use immediately.

🔋 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.
