🔋 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.

Revive your OnePlus 6 with this BLP657 3300mAh replacement battery. Released in May 2018, the OnePlus 6 was a flagship killer featuring a 6.28-inch AMOLED display, Snapdragon 845 processor, and the iconic notch design. The 3300mAh battery combined with Dash Charge fast charging provided excellent all-day performance. After 6-7 years of use, the original battery has likely degraded significantly. This Li-ion Polymer battery restores the full 3300mAh capacity, bringing back the reliable “fast and smooth” experience OnePlus was known for. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Why This Battery Replacement Matters for OnePlus 6 Users: The OnePlus 6 was beloved for its balanced performance, clean OxygenOS, and dash charge. The 3300mAh battery originally provided approximately a full day of moderate use. However, after years of charging cycles, the original battery’s capacity drops significantly. Common symptoms include: the phone needing multiple charges per day, shutting down at 15-25% battery remaining (a well-known OnePlus 6 aging issue), slower charging than originally, or the battery swelling. This replacement restores the original battery life, saving you from buying a new phone. The BLP657 battery is also compatible with the phone’s 20W Dash Charge fast charging — reaching approximately 50% in 30 minutes. OxygenOS is optimized for battery efficiency, and a fresh battery brings back the smooth, responsive experience the phone was known for.
Compatibility Note: Fits OnePlus 6 (A6000, A6003) only. Please confirm your battery model before ordering — BLP657 is printed on your original battery. This battery is NOT compatible with OnePlus 6T (which uses BLP685 battery), OnePlus 5, OnePlus 5T, OnePlus 7 series, or other OnePlus models. The A6000 and A6003 are the standard OnePlus 6 variants; using a different battery model may cause charging issues or incorrect battery reporting.

This battery is NOT compatible with OnePlus 6T (which uses BLP685), OnePlus 5, OnePlus 5T, OnePlus 7 series, or other OnePlus models. If your OnePlus 6 battery drains quickly or won't hold a charge, this BLP657 replacement battery will restore full performance.

The BLP657 3300mAh battery for OnePlus 6 has a typical capacity of 3300mAh (12.70Wh) and a rated voltage of 3.85V, with a charge limit of 4.4V. This BLP657 3.85V 3300mAh Li-ion Polymer battery is built with grade A cells and is CE, RoHS, and UN38.3 certified. For OnePlus 6 battery life after replacement, expect approximately a full day of moderate use on a single charge. The OnePlus 6 3300mAh battery performance provides solid endurance for daily tasks, gaming, and media consumption. Charging the OnePlus 6 battery with the original 20W Dash Charge adapter takes approximately 30 minutes to 50% and 80-90 minutes to full.

If your original battery now requires daily multiple charges or shuts down at 15-25% remaining (a common OnePlus 6 issue), this replacement will restore the original battery life.

Professional OnePlus 6 battery installation is recommended. The OnePlus 6 has a sealed glass back with strong adhesive. To replace OnePlus 6 battery A6000, the technician must heat the back cover to soften adhesive, carefully pry it open to avoid cracking the glass, disconnect the battery's small 2-pin connector, remove the old battery (lightly adhered), and install the new BLP657 battery before resealing. The 6.28-inch AMOLED display is fragile, and improper prying can damage it. Third-party repair shops typically charge $20-35 for labor. OnePlus official battery replacement costs vary by region. For OnePlus 6 battery health maintenance: 1) Use only the original OnePlus Dash Charge charger and cable for optimal charging. 2) Keep battery level between 20% and 80% for daily use to maximize lifespan. 3) Avoid exposing the phone to high temperatures (above 40°C / 104°F), especially while charging. 4) For long-term storage (over 2 months), keep the battery at approximately 40-60% charge. 5) Perform a full calibration cycle after installation: drain the phone until it auto-shuts off, then charge uninterrupted to 100% using the original Dash Charge charger. For OnePlus 6 battery care tips, stop using immediately if the battery shows any swelling.
