iPhones often signal impending battery problems, and users should pay attention to these cues. One primary indicator is the Battery Health feature located in the device’s settings. This feature provides insights into the battery’s capacity over time. A new iPhone’s battery starts at 100% health, which then declines due to regular charging and usage. As this percentage decreases, it offers a heads-up about the need for potential battery replacement. A battery health reading of 80% or lower signifies that the battery’s performance has degraded and its ability to hold a charge is reduced. This also impacts the resale value of the device.
