iPhone 12 Pro Battery Replacement

The iPhone 12 Pro is powered by a 2,815 mAh high-efficiency lithium-ion battery, engineered to support the A14 Bionic chip’s performance while maintaining strong all-day usage. If your battery drains quickly, shuts down early, or iOS displays a “Service Recommended” warning, a premium replacement restores full performance, stability, and longevity.
