iPhone 13 Pro Max battery capacity drops rapidly. Bought the phone in August 2022. The first percent dropped on July 1, 2023. Now it has 92 percent on it already. Dropping steadily every 3 weeks (at least the last 3-4 percent). I don't heat it up, it works fine. Always charge to 95-100 percent. App Vay Tiền.
