Apple iPhone 11 Original-Capacity Replacement Battery (3110mAh)

The iPhone 11 battery is a high-grade internal Lithium-ion Polymer cell built in a standard rectangular shape, tailored for the power demands of Apple’s highly successful 6.1-inch Liquid Retina base flagship. This battery works hand-in-hand with the advanced power-efficiency management of the A13 Bionic chip.

Over a few years of usage, standard chemical degradation causes the cell’s maximum capacity to drop. When it falls below 80% (Settings > Battery > Battery Health), iOS locks the device into a performance-throttled profile to prevent abrupt brownouts. This shows up as classic usability issues: UI animations stuttering under workload, significant lagging while multitasking or launching the camera app, fast energy drain on mobile data, and sudden power cuts when the phone sits below 20%. Replacing the degraded cell unlocks the processor, instantly returning your iPhone to its snappy factory operational speeds and stable all-day runtime.
