🔋 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.

Professional installation is strongly recommended for Huawei Mate 20X battery replacement. The Mate 20X has a sealed design with a glass back cover secured by strong adhesive — the battery is not user‑replaceable. The process to replace the battery requires heating to soften adhesive, careful prying to avoid damaging the display or back cover, and proper reassembly. The phone has no official IP water resistance rating, so water seal maintenance is not a concern after replacement. If you choose DIY phone battery replacement, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), use plastic tools to avoid damaging internal components, and never reuse a battery after removal. Third-party repair shops typically charge $15‑30 for labor.
