Apple iPhone 6s (6SG) Original-Capacity Replacement Battery (1715mAh)

The iPhone 6s battery (often labeled in component markets as iPhone 6s or 6S/6SG) is an internal Lithium-ion cell engineered specifically for Apple’s 4.7-inch smartphone featuring 3D Touch. Because these devices have been in service for a long time, factory batteries are almost universally degraded.

When iOS battery health falls below 80%, Apple’s dynamic power management throttles peak CPU performance to prevent unexpected shutdowns. This leads to common system faults: noticeable lagging when typing, stuttering animations, rapid percentage drops during video playback, or the phone shutting off entirely under 20%. Swapping in a premium-grade replacement cell removes performance throttling, restoring original CPU speeds and stable daily backup.
