Apple iPhone 12 / 12 Pro Original-Capacity Replacement Battery (2815mAh)

One of the best design choices Apple made for this generation was making the iPhone 12 and iPhone 12 Pro batteries completely identical and cross-compatible. Both smartphones feature the exact same internal rectangular Lithium-ion footprint, which powers either the power-efficient A14 Bionic chip or the Super Retina XDR OLED displays.

As these devices cross multiple years of active use, chemical degradation takes its toll. When maximum battery health drops below 80% (Settings > Battery > Battery Health), iOS activates dynamic power throttling. You will immediately notice performance bottlenecks: the phone overheating when charging or playing casual games, micro-stutters while scrolling, laggy camera shutter deployment, and abrupt power blackouts when the battery percentage dips below 15%. Replacing the worn-out cell instantly unblocks the system processor, giving you back smooth performance and a reliable day’s worth of runtime.
