My iPhone 14 Pro Max has been stuck at 85% battery life for almost eight months. I wonder what is going on; it seems like Apple is playing with customers to replace their batteries under Apple Care.

Batteries, like people are individuals. No two people age exactly the same and batteries don’t age the same either. The exact usage, chemical makeup, 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 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.
Please review the Apple Support articles on battery optimization. It contains the best current practices for battery charging.

Hello,
Well the iPhone 14 has been out for about two years.
So, depending on usage, that is normal and is nothing to worry about. Generally, Apple will replace the battery under warranty if the battery health falls below 80% during the first year.

Good luck.
If you are concerned about the battery, make an appointment at the Apple Store / Genius Bar or an authorized Apple service shop to have the battery checked and tested.
