iOS 18 brings a useful addition to its battery settings, notifying users when their iPhone is connected to a slow charger. Located within the battery section of Settings, this new feature displays "Slow Charger" alongside an information icon, providing insights into the charging speed.
First noted by a user on Reddit, tapping the information icon directs users to a placeholder support document, indicating that more detailed information will follow in subsequent updates.
Currently, this notification appears exclusively in the battery settings, without accompanying alerts or notifications. It aims to inform users about the charging speed without posing any risk of damage to the device. For instance, charging an iPhone 15 Pro Max with a 5W charger, like the one-inch model historically included by Apple, will extend charging times considerably compared to higher wattage chargers available for the device.
While iOS 18's initial beta release introduces this feature, future updates may enhance its visibility, potentially integrating alerts for users to optimize charging efficiency on their iPhones.
