🔋 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.

Frequently Asked Questions

The HB576675EFW battery is compatible with Huawei Mate 40 Pro, Mate 40 Pro+, Mate 40 RS Porsche Design, and Mate 40E Pro. The Mate 40 Pro was released in October 2020 featuring a 6.76-inch OLED display and supports 66W fast charging. If your Mate 40 Pro battery drains quickly or won't hold a charge, this is the correct replacement. Please note that some third-party sellers list the battery as HB576675EEW — the EFW and EEW models are interchangeable. For reference, Huawei official battery replacement costs 199 RMB ($27) with a one-year warranty.

The HB576675EFW battery has a capacity of 4400mAh (16.94Wh) and a rated voltage of 3.85V. Charge limit voltage is 4.45V. It is a Li-ion Polymer battery built with grade A cells and is CE, RoHS, and UN38.3 certified. The battery supports the original 66W wired fast charging and 50W wireless charging capabilities of the Mate 40 Pro. The Mate 40 Pro also supports reverse wireless charging for other devices. For reference, used Mate 40 Pro phones sell for approximately $300-400 on the second-hand market.

Professional installation is recommended, but the Mate 40 Pro is known for its relatively repairable design. According to teardown reviews, the battery features an easy-pull tab, making removal simpler than many sealed phones. After removing the back cover and mid-frame, you can access the battery and pull the tab to release it. However, professional installation is still suggested to maintain water resistance and avoid damaging the display. If you choose to DIY, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), and never reuse a battery after removal. Third-party repair shops typically charge $15-30 for labor, while Huawei official service charges 199 RMB ($27) including installation with a one-year warranty.
