Revive your OPPO Reno 3 or Reno 3 Pro with this BLP755 4025mAh replacement battery. Both devices feature a 6.4-inch/6.5-inch AMOLED display, Snapdragon 765G processor, and support 30W VOOC fast charging. This Li-ion Polymer battery restores the original 4025mAh capacity for full-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.
Compatibility Note: Fits OPPO Reno 3 (CPH2043) and OPPO Reno 3 Pro (CPH2035, CPH2036, CPH2037). Please confirm your battery model before ordering — BLP755 is printed on your original battery. If your Reno 3 or Reno 3 Pro battery drains quickly or won’t hold a charge, this is the correct replacement. Professional installation is recommended as the phone has a sealed design.
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 30W VOOC charger. If you notice swelling or overheating, stop use immediately.

✅ 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.
| Compare | ✅ Qingsm Tech | ⚠️ eBay / AliExpress |
|---|---|---|
| Warranty Period | 90 days from delivery | 15-30 days from order confirmation |
| When It Starts | 📦 Upon delivery | ⚠️ Upon order confirmation (even before you receive it) |
| Claims Handling | We do it directly — email us | Automated dispute system, seller dependent |
| After Window Expires | Still can contact us for support | No recourse, seller can ignore you |
🔋 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.
