Restore the battery life of your Nubia Z70 Ultra with this Li3959T45P8h816758 6150mAh replacement battery. Released in November 2024, the Nubia Z70 Ultra features a 6.85-inch 144Hz 1.5K AMOLED display, Qualcomm Snapdragon 8 Elite processor, and IP68/IP69 dust/water resistance. This Li-Polymer battery uses advanced silicon-carbon anode technology (Nubia’s “Second Generation South Sea Battery”) — delivering the factory-rated 6150mAh capacity for extended all-day usage.
Built with high-quality 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 battery supports 80W wired fast charging with PD3.0 and QC4 compatibility — according to official testing, the phone can charge from 0% to 100% in approximately 39 minutes under normal conditions.[reference:0]For reference, third-party retailers sell this battery for approximately $25 to $45.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches Li3959T45P8h816758. This battery is compatible with Nubia Z70 Ultra (models NX733J, NX736J). Professional installation is recommended as the phone has a sealed design with strong adhesive and IP68/IP69 water resistance — proper resealing is required to maintain protection 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 80W fast charging performance, use the original Nubia charger and cable that came with your phone. If you don’t use the battery 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.
