iPhone 15 pro max battery health drop 1% after updating to 17.1.2

After updating to version 17.1.2, my iPhone 15 Pro Max experienced a 1% decrease in battery health over 39 days. Before the update (17.1.1), the battery health remained at 100%, and since the software update, it has dropped to 99%. 😒

iPhone 15 Pro Max, iOS 17

This has nothing to do with the software update. Battery health declines with battery usage, that is the way it is. After a time using the phone, the battery health will drop, this are the batteries normal chemical processes. You won't need to worry about this. IF the battery health reaches 80% the battery is severely depleted and you can opt in for a replacement
