When to replace iphone battery

Although the Performance Management may not have been used, your battery may still have a low capacity. This may just mean that you haven’t been in a circumstance where an unplanned shutdown would have occurred. The feature may, however, be activated if you were to play a graphically demanding game while the battery was below 20%.

If you receive a notification that your battery health has declined, you can still use your phone, but you may encounter a lower charge capacity and a few minor stability difficulties. The best course of action is to have your battery checked out by a certified service professional, who may recommend a new battery or repair your existing one if necessary.

The following are some signs that your iPhone could need a new battery: The illumination is less bright than usual, the speaker level is lower, the screen stutters when scrolling, some game apps have reduced frame rates, and it takes longer for an app to load.
