Power up your ASUS ROG Phone 3 with this C11P1903 6000mAh replacement battery. Released in July 2020, the ROG Phone 3 features a 6.59-inch 144Hz AMOLED display, Snapdragon 865+ processor, and supports 30W HyperCharge (10V/3A) fast charging via USB-C — capable of reaching 4,510mAh (75% of total capacity) in just 46 minutes. This Li-Polymer battery delivers the factory-rated 6000mAh capacity for extended gaming sessions, high-refresh-rate display usage, and intensive multitasking. For reference, third‑party retailers sell this battery for approximately $25 to $45.
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 durability.
Compatibility Note: Please power down your device and check your original battery label before ordering. This battery is compatible with ASUS ROG Phone 3 (ZS661KS, ZS661KL, ASUS_I003D, I003DD). Professional installation is strongly recommended as the battery is not user‑replaceable — the phone has a sealed back cover with strong adhesive.
⚠️ Important Note: This battery shares the same physical dimensions as the original. It is a Class 1 Laser Product; do not look directly into the laser beam of the ROG Phone 3’s AirTrigger sensors during operation.
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 30W HyperCharge performance, use the original ASUS 30W charger (10V/3A) and cable. 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.
