Apple iPhone XS Max Original-Capacity Replacement Battery (3174mAh)

The iPhone XS Max battery is a premium internal Lithium-ion cell engineered in a single-cell, space-saving L-shaped design to maximize efficiency inside Apple’s large 6.5-inch flagship chassis. This model coordinates closely with the power-management arrays of the A12 Bionic chip to drive its large Super Retina OLED display.

When your maximum battery capacity degrades below 80% under Settings > Battery > Battery Health, iOS enforces performance throttling to prevent unexpected brownouts under heavy processing loads. This manifests as noticeable system slowdowns: lagging while opening the camera or heavy apps, interface stuttering, rapid percentage drops on mobile data, or the phone shutting off abruptly at 15% to 20%. Swapping in a premium-grade cell completely unblocks the processor, restoring original computing fluidities and full-day standby runtimes.
