🔋 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 legendary fast charging performance of your OnePlus 8 with this BLP761 4320mAh replacement battery. Released in April 2020, the OnePlus 8 features a 6.55‑inch 90Hz Fluid AMOLED display, Qualcomm Snapdragon 865 processor, 8GB/12GB RAM, 128GB/256GB storage, and supports OnePlus‘s proprietary Warp Charge 30T technology — capable of charging from 0% to 50% in just 23 minutes and to 100% in approximately 80 minutes. This Li‑ion battery delivers the factory‑rated 4320mAh capacity for all‑day usage, keeping you powered through 5G connectivity, gaming, and multitasking. For reference, third‑party retailers sell this battery for approximately $18 to $35.
Built with Grade A Li‑ion cells and multi‑layer safety protection against overcharge, over‑discharge, short circuit, and overcurrent. With a cycle life of 500+ full charge cycles retaining 80% capacity, this replacement battery is designed for long‑term durability. The battery also features no memory effect — allowing you to charge at any time without affecting lifespan. Professional installation is strongly recommended as the battery is not user‑replaceable — the phone has a sealed back cover with strong adhesive.
Compatibility Note: Please power down your device and check your original battery label before ordering. This battery is compatible with OnePlus 8 (IN2010, IN2013, IN2017, IN2019) only — NOT compatible with OnePlus 8 Pro or OnePlus 8T Pro. The phone 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 Warp Charge 30T performance, use the original OnePlus 30W Warp charger and cable that came with your phone (charges from 0% to 50% in 23 minutes). 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.
