Restore the legendary 150W ultra-fast charging capability of your Realme GT Neo 3 with this BLP919 4500mAh dual-cell replacement battery. Released in March 2022, the Realme GT Neo 3 150W edition set a new industry standard for charging speed, featuring a unique dual-cell series battery architecture and realme’s proprietary UDCA (UltraDart Charging Architecture) system. According to official specifications from realme Lab, the 150W UltraDart system can charge the battery from 0 to 50% in just 5 minutes using the included 20V/8A (MAX) adapter, and reach 100% in approximately 15 minutes — making it one of the fastest-charging smartphones ever produced when it launched. This remarkable charging speed is achieved through the dual-cell design, which allows higher power input while maintaining safe temperatures.
About the Dual-Cell Series Design (2S Architecture): The Realme GT Neo 3 150W employs a dual-cell series battery architecture, where two 2250mAh cells are connected in series to deliver 7.74V total voltage (3.87V × 2). This 2S design is fundamentally different from the single-cell batteries found in most smartphones. The series configuration enables the battery to accept higher charging voltages (up to 8.9V charge limit), which is essential for achieving 150W power delivery. The BLP919 battery is built with grade A Li-ion Polymer cells and features multi-layer safety protection against overcharge, over-discharge, short circuits, and overheating. According to realme’s official specifications, the battery is designed to retain ≥80% of its original capacity after 1,600 full charge cycles — significantly exceeding the industry standard of 500-800 cycles. The system includes 38 levels of safety protection and dual FPC battery connectors for stable current management. CE, RoHS, and UN38.3 certified.
Compatibility Note — Important Distinction: This BLP919 battery is specifically designed for the Realme GT Neo 3 150W version (models RMX3560, RMX3561). Please note that the 80W version of GT Neo 3 uses a different battery model — BLP887 — which has a 5000mAh single-cell design and is NOT compatible with this battery. Installing the wrong battery will result in charging issues and potential damage. Before ordering, please verify your device model in Settings > About Phone and check that your original battery model is BLP919. The 150W version can be identified by the 150W branding on the included charger and the charging specifications in the system settings. If your phone is the 80W version (5000mAh battery), please search for BLP887 battery instead.
Installation Warning for Dual-Cell Battery: Professional installation is strongly recommended for this dual-cell battery. The Realme GT Neo 3 has a sealed design with strong adhesive, and the dual-cell architecture requires careful handling of two cells connected in series. Improper handling may damage the battery management system or the display. For safety, always use the original 150W charger (20V/8A) and the 10A-rated USB cable that came with your device to ensure optimal fast charging performance and battery longevity. If you notice any swelling or overheating, stop use immediately.
Battery Care Tips for 150W Fast Charging: To maximize the lifespan of your new dual-cell battery, we recommend avoiding full discharge — keep battery level above 20% for daily use. While the GT Neo 3’s 150W system is designed for high-speed charging, occasional use of slower charging (via standard USB-PD chargers) may help extend long-term battery health. Do not expose the battery to high temperatures or direct sunlight. New batteries may require 3-5 full charge cycles to reach optimal capacity. For the best fast charging experience, use the original 160W/150W charger and the high-current 10A cable that came with your device.

🔋 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.
