You can replace your iPhone battery once it reached 80%, but if it’s worth to replace battery or not? It depends, as the software updates, its load on device increases, so battery and all device’s components have to work hard to meet that load which reduces maximum capacity of battery quickly. For example, I have an iPhone 11 which was released with iOS 13 and device was Able to keep up with software load, but now it’s iOS 17 and iOS 18 is coming soon, so they are more heavier for system. Even though device is compatible for iOS 17 or 18 but still device’s components work hard and battery automatically works hard to meet those demands so it’s affects it’s battery life. This was explained to me by an apple support advisor.

Batteries, like people are individuals. No two people age exactly the same and batteries don’t age the same either. The exact usage, chemical make, storage conditions, exposure to heat and cold and about a dozen other factors mean that every battery ages differently. Battery aging is not a linear (straight line) and degrades at different rates as the chemicals in the battery age and the other factors mentioned above. Apple expects your battery health to be at 80% after 24 months. If your battery health misses that expectation, contact Apple Support.
