Using diagnostics in iOS, we've detected that the battery in your iPhone may need to be replaced. When a battery gets closer to the end of its lifespan, the amount of charge and the ability to provide power reduces. As a result, a battery may need to be charged more and more frequently and your iPhone might experience unexpected shutdowns.

This isn’t a safety issue; it’s just to let you know that your battery may need to be replaced. You can continue to use your iPhone until you have your battery checked. In the meantime, you might notice longer app launch times, lower frame rates while scrolling, and other reductions in performance.

All rechargeable batteries are consumables and have a limited lifespan, eventually needing to be serviced or recycled. There are various factors that can affect the performance and lifespan of your device’s battery, including number of charge cycles, chemical aging of your battery, and exposure to extreme heat or cold.
