✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 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 battery life of your vivo X300 with this BB25 6040mAh replacement battery. The vivo X300 features a 6.31-inch 1.5K LTPO AMOLED display and supports 90W wired FlashCharge and 40W wireless FlashCharge — reaching full charge in approximately 30 minutes. This Li-ion battery delivers the factory-rated 6040mAh typical capacity for all-day use. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Important Notes: The vivo X300 has a sealed design with adhesive-secured battery. Professional installation is strongly recommended. For reference, vivo official battery replacement through the “Battery Renewal Program” costs approximately 150-199 RMB ($21-27) including service. After installing a third-party battery, the phone functions normally — this is an industry-standard replacement part.
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 lifespan, use a certified 90W charger. If you notice swelling or overheating, stop use immediately.

Frequently Asked Questions

The BB25 battery is compatible with vivo X300. The X300 was released in October 2025 featuring a 6.31-inch 1.5K LTPO AMOLED display and supports 90W FlashCharge. If your X300 battery drains quickly or won't hold a charge, this is the correct replacement. For reference, vivo official battery replacement through service centers costs 150-199 RMB ($21-27) including installation. Please verify your device model in Settings > About Phone before purchasing.

The BB25 battery has a typical capacity of 6040mAh (rated capacity 5925mAh) and a rated voltage of 3.77V. Charge limit voltage is 4.4V. This Li-ion battery is built with grade A cells and is CE, RoHS, and UN38.3 certified. The battery supports the original 90W wired FlashCharge and 40W wireless FlashCharge capabilities of the vivo X300 — with the original 90W charger, the phone can reach full charge in approximately 30 minutes.

Professional installation is strongly recommended. The vivo X300 has a sealed design with strong adhesive. Replacing the battery requires heating to soften adhesive and careful prying to avoid damaging the AMOLED 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. Incorrect installation may damage the phone or break water resistance. Third-party repair shops typically charge $15-30 for labor.
