FAQ
-
Why doesn’t this battery trigger the “Unknown Part” pop-up on iPhone 15? This battery integrates a genuine Texas Instruments (TI) gauge chip and self-diagnosis logic. It fully replicates the OEM communication protocol, allowing iOS to read the component as original, bypassing the pop-up warning and showing 100% maximum capacity.
-
Is the 3520mAh capacity safe, and will it cause the battery to swell? Yes, it is entirely safe. The capacity increase is achieved by using higher energy density pure cobalt (LiCoO2) materials, not by expanding the physical dimensions. It fits perfectly within the iPhone 15 chassis with zero risk of swelling under standard thermal conditions.
-
What is the cycle life of this pure cobalt battery cell? The pure cobalt chemistry offers an internal resistance below 35 milliohms, resulting in a verified cycle life of over 800 charge-discharge cycles while maintaining at least 80% of its original capacity.
-
What is your Minimum Order Quantity (MOQ) for B2B wholesale? We understand the need for strict quality control. Our MOQ for sample testing is typically 10 to 50 pieces. For standard factory-direct wholesale pricing, the MOQ begins at 100 units.
-
Do you provide OEM packaging services for repair center chains? Yes. For bulk orders, we offer comprehensive turnkey solutions, including custom silk-screen printing on the battery cells, neutral packaging, and fully branded retail boxes tailored to your business needs.
-
What certifications do you provide for international shipping? Our batteries comply with strict international shipping standards. We provide UN38.3, MSDS, CE, and RoHS certifications, ensuring safe and customs-compliant sea or air freight to your destination.
