Restore the flagship performance of your iQOO 7 with this B-P3 4000mAh replacement battery. Compatible with iQOO 7 (V2049A, I2009) and iQOO 7 Legend, this dual‑cell Li‑Polymer battery uses a series design — two 2000mAh cells connected in series — to achieve a combined output of 7.74V, delivering the factory‑rated equivalent 4000mAh capacity. The iQOO 7 was released in January 2021 featuring a 6.62‑inch 120Hz AMOLED display, Qualcomm Snapdragon 888 processor, and industry‑leading 120W FlashCharge technology — capable of charging from 0% to 100% in just 15 minutes. The phone features dual 6C high‑rate cells, array‑type tab structure, dual temperature sensors, and 98.5% conversion efficiency charge pump chips. For reference, third‑party retailers sell this battery for approximately $25 to $40.
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. The device supports 120W FlashCharge — when paired with the original Vivo 120W charger (20V/6A) and compatible USB‑C cable, the 4000mAh battery can be fully charged in approximately 15 minutes (officially tested). Professional installation is strongly recommended as the battery is not user‑replaceable — the phone has a sealed back cover with strong adhesive. The phone has no official IP water resistance rating, so water seal maintenance is not a concern after replacement.
Compatibility Note: Please power down your device and check your original battery label before ordering. Ensure the model number printed matches B-P3. This battery is compatible with iQOO 7 (V2049A, I2009) and iQOO 7 Legend only — NOT compatible with iQOO 7 Pro or other iQOO models. The battery is not user‑replaceable — professional installation is strongly recommended as the phone has a sealed design with strong adhesive.
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 120W FlashCharge performance, use the original Vivo 120W charger and cable 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.

🔋 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.
