Why the notice appears?
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.
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.
How to solve this problem?
To get help with a battery replacement, contact Apple Support for service options.
Apple’s one-year warranty, AppleCare+, and consumer law include service coverage for a defective battery. If your battery doesn’t have service coverage, Apple offers a battery replacement service for a fee.
