🔋 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.

Restore the powerful performance of your Meizu MX4 Pro with this BT41 3350mAh replacement battery. The Meizu MX4 Pro was released in November 2014 as a flagship device, featuring a 5.5-inch 2K+ display (2560×1536 resolution) with 76.5% screen-to-body ratio, Samsung Exynos 5430 octa-core processor, 3GB RAM, and a 20.7MP Sony rear camera. This Li-Polymer battery delivers the factory-rated 3350mAh capacity — providing all-day power for calls, messaging, multimedia, and gaming.
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. With a cycle life of 500+ full charge cycles, this replacement battery is designed for long-term reliability. The battery is non-removable — professional installation is strongly recommended as the phone has a sealed design with strong adhesive.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches BT41. This battery is compatible with Meizu MX4 Pro (models M462, MX4SWDS0, M462U) and Meizu MX4. The device 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 charging performance, use the original 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.
