Wireless Flex battery for iPhone 13. If the battery health is reduced, this replacement part restores performance and battery life. The battery is designed to retain about 80% of its original capacity after 500 full charge cycles. Once this limit is exceeded, more frequent charging is required. It is recommended to replace worn batteries with new ones.

Notes:

• After replacement, a warning message about the battery's authenticity may appear, without affecting the device's functionality.
• If the health of the old battery is above 90%, it takes about 2–3 weeks for the capacity to be fully restored.
• If the health is below 80%, restoration to 100% is difficult.
• With a high-capacity cell, full restoration can be achieved in 3–5 days if the old battery has a health level above 90%.
• The simplest installation method is using a flex cable.
