Core Product Advantages
Upgraded battery capacity delivers improved overall phone runtime compared with standard-capacity batteries.
Built-in Ti-chip protection board precisely regulates charge-discharge current with multi-layer protection against over-charge, over-discharge, over-current and high temperature. It guarantees accurate power metering, mitigates sudden battery-level jumps and unexpected power-off for stable handset performance.
Brand-new zero-cycle delivery with strictly controlled cell internal resistance. Low-resistance design ensures stable discharge output, reduces heat generation and lowers swelling risk.
Retains over 80% battery health after more than 500 full charge-discharge cycles, effectively extending the overall service life of the phone.
Improved insulating protective housing matches original cavity dimension precisely. No swelling after installation and avoids squeezing surrounding components.
Fully compatible with all iOS versions. Basic battery status information can be normally recognized and read after replacement.
Every unit passes comprehensive factory reliability tests. Suitable for bulk stocking for offline repair shops and supports large-volume cross-border export orders.
Production & Quality Control
Standardized quality control is implemented on the full production line. Performance verification is conducted for cells, Ti-chip protection boards and auxiliary materials before warehousing. Finished units go through charge-discharge, impedance and high-low temperature simulation tests. Independent batch trace codes are assigned for full traceback and consistent bulk quality.
OEM & ODM Cooperation
Spot bulk purchase and custom development are supported, including private-label LOGO printing and custom packaging. Standard sample lead-time: 5-7 days; full ODM project lead-time: 2-4 weeks. Our partners include overseas brand owners, importers and offline chain repair service providers.
