Is your device dying rapidly, shutting down unexpectedly at 20%, or noticeably swelling and pushing the screen upward? Restore your all-day power and peak performance with this Premium Factory-Spec Replacement Battery. Engineered specifically for the Apple iPhone 14 Pro Max, this zero-cycle lithium-ion cell delivers the exact voltage and capacity required to handle Apple's demanding A16 Bionic processor and ProMotion display.

Quality Tier: Premium (Factory-Spec Unpaired Component)
Unlike standard aftermarket batteries that permanently disable your Battery Health metrics, this is a Factory-Spec, unpaired component. It is designed to interface directly with Apple's native iOS Repair Assistant. This means you get a top-tier, high-density lithium-ion core with zero previous charge cycles, alongside full software compatibility.

Standout Engineering Features

• Native iOS Calibration: Fully compatible with the built-in iOS repair tool (System Configuration). Once installed, the device will natively pair with this battery's logic board.
• Zero-Cycle Guarantee: 100% brand new internal cells, ensuring you get the maximum possible lifespan out of the replacement.
• Advanced TI Fuel Gauge IC: Integrated with a premium Texas Instruments control chip to accurately communicate voltage drops to the logic board, preventing random shut-offs.

Important Diagnostic Note (Native Battery Health Restoration & Pairing)
Because this is a Factory-Spec, unpaired component, no micro-soldering or BMS board transfer is required. After installing this battery, your iPhone will display an "Unknown Part" message initially. Simply navigate to your iOS Settings and run the native Repair Assistant / System Configuration tool to pair the new component.

Multi-Part Calibration Tip: If you are replacing multiple serialized components (such as a battery and a display) during the same repair session, we highly recommend running the configuration tool one part at a time. Attempting to pair multiple unverified parts simultaneously can cause the iOS Configuration process to hang or fail.

Once the pairing process is complete, the warning will disappear, and your Battery Health & Charging maximum capacity percentage will be 100% fully functional.

Safety Warning: Puncturing a lithium-ion battery during removal can cause a dangerous thermal event (fire). Always discharge your old battery below 25% before attempting the repair, and use isopropyl alcohol to safely dissolve the old adhesive strips.
