Important Installation & iOS Software Notice

Understanding the Apple Battery Message

We want to be completely transparent about what happens when you install your new Haisic iphone 14promax battery. Apple’s iOS software is designed to automatically display an “Important Battery Message” or an “Unknown Part” notification whenever a new battery is installed.

What to expect after installation:

• Disabled Battery Health: The built-in battery health percentage in your iPhone settings will no longer display a reading.
• The Microsoldering Workaround: To remove iPhone non-genuine battery warning alerts and keep your system health tracking active, the original Apple Battery Management System (BMS) board must be moved to the new cell. This is an advanced repair that requires an iPhone battery BMS spot welding cell transfer performed by a microsoldering professional.
• Uncompromised Performance: This iOS notification is strictly a software alert. It does not throttle your device or affect the safety, charging speed, or daily runtime of your iPhone 14 Pro Max replacement battery.

You can rely on this cell to fully deliver its upgraded 4770mAh capacity from day one. We engineer these smartphone replacement parts with the exact same industrial-grade safety and stability protocols used in our heavy-duty 48V battery bank systems, guaranteeing reliable power regardless of Apple’s software warnings.
