“Experts including Kyle Wiens, chief executive of the repair organization iFixit, said that we should have our phone batteries replaced every two to three years.” Apple.com: “Learn about the built-in software and hardware system that iPhone 11 models and later use to reduce performance effects as your battery chemically ages. About performance as batteries age – The software and hardware system built into your iPhone is automatic, always-on, and works to provide the best possible performance as battery aging occurs over time. The power needs of your iPhone are dynamically monitored, and the system manages performance so that it can address these needs in real time. The system allows your iPhone to reduce performance effects from battery aging. While the system reduces performance effects as much as possible, battery aging might still eventually lead to noticeable, possibly temporary, effects. Depending on the battery state, level of charge, and the tasks that your iPhone is handling, examples might include longer app launch times and lower frame rates. You might also see increased processing times, reduced wireless-data throughput, backlight dimming, or lower speaker volume. In extreme cases, the camera flash or other camera features might be temporarily disabled.
