🔋 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.

Charge limit voltage: 8.9V (4.45V × 2 cells in series)

Package include: 1 x battery (complete dual-cell assembly)
Restore elite gaming power to your Red Magic 9 Pro+ or 9S Pro+ with this Li3927T89P8H613485 5500mAh dual-cell replacement battery. Released in mid-2024, the Red Magic 9 Pro+ and 9S Pro+ are among the most powerful gaming phones ever created, featuring 6.8-inch AMOLED displays, Snapdragon 8 Gen 3 processors, and active cooling fans. The 9S Pro+ variant was designed for competitive gamers who demand both extreme performance and ultra-fast charging — the 5500mAh battery delivers a full charge in approximately 16 minutes with 165W fast charging. This dual-cell Li-ion Polymer battery restores the full 5500mAh capacity, bringing back the marathon gaming endurance these devices were 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 Competitive Gaming and Ultra-Fast Charging: The Red Magic 9 Pro+ and 9S Pro+ use a dual-cell series battery design — two cells connected in series, producing a total voltage of 7.78V (3.89V × 2) and an equivalent total capacity of 5500mAh (2750mAh × 2). This architecture enables the 165W fast charging capability that sets these gaming phones apart. After years of intensive gaming sessions and daily charging cycles, the original battery capacity naturally degrades. Common symptoms include: the device requiring multiple charges during a gaming session, unexpected shutdowns at 15-25% battery remaining, slower charging than the original 16-minute full charge time, or visible battery swelling. This replacement restores the original battery life and ultra-fast charging performance, extending the useful life of the device without the cost of a new gaming phone. The battery is supplied as a complete dual-cell assembly — one physical unit containing both cells — ensuring correct installation and balanced charging.
Compatibility Note: Fits Nubia Red Magic 9 Pro+ and Red Magic 9S Pro+ only. Some listings refer to the single-cell rating (2750mAh at 3.89V) instead of the total capacity — this battery is the complete dual-cell assembly with 5500mAh total equivalent capacity. Please confirm your battery model before ordering — Li3927T89P8H613485 is printed on your original battery. This battery is NOT compatible with Red Magic 8 Pro, Red Magic 9 Pro (standard), Red Magic 10 Pro, or other Nubia models.

The active cooling fan and RGB lighting components are fragile, and improper handling can damage them. Third-party repair shops with gaming phone experience typically charge $25-45 for labor. For Li3927T89P8H613485 battery installation Red Magic 9 Pro+, this is not a DIY-friendly replacement due to the complex internal layout. For Red Magic 9 Pro+ battery health maintenance for gamers: 1) Use only the original 165W charger and cable for optimal ultra-fast charging. 2) Avoid charging while playing intense games for extended periods — the combination of charging heat and processor heat can accelerate battery degradation. 3) Keep battery level between 20% and 80% for daily use to maximize lifespan. 4) Avoid exposing the device to high temperatures (above 40°C / 104°F). 5) For long-term storage (over 2 months), keep the battery at approximately 40-60% charge. 6) Perform a full calibration cycle after installation: drain the device until it auto-shuts off, then charge uninterrupted to 100% using the original 165W charger. For Red Magic 9S Pro+ battery care tips, stop using immediately if the battery shows any swelling.
