This is a battery cell without a flex cable. If the device’s battery health is low, this is the replacement part needed to restore battery life. Replace the original battery with this new component and restore the iPhone’s performance to the maximum.

An iPhone battery is designed to retain 80% of its original capacity after 500 charge cycles. Once this limit is exceeded, the battery will need to be charged more and more often. To avoid this, it is recommended to replace the old battery with a new one.

After replacing the battery, the phone may display a warning message about “authenticity.” This can happen even if the replacement part is a genuine Apple product. This message can be ignored and does not affect the device’s operation.

• Compatibility: iPhone 11 Pro Max
• Capacity: 3969mAh
• If the old battery’s health is above 90%, it takes 2~3 weeks to recover.
• If the old battery’s health is below 80%, it is difficult to reach 100% again.
• If a high-capacity cell is used and the old battery’s health is above 90%, it takes only 3~5 days to recover to 100%.
• Batteries below 80% can eventually rise above 90% as capacity increases with charge cycles.

The easiest way is to use a flex cable, but the programmable machine reduces the cost and works just as well.
