iPads and iPhones are portable devices, and under normal circumstances, a single charge is sufficient for a full day of use. However, sometimes the iPad or iPhone will be connected to the power supply for a long time. For example, some iPad users, for the convenience of use at any time or worrying about forgetting to charge the iPad, will connect the device to the power supply for a long time without unplugging it. Doing this will affect the device and battery? make an impact?
Apple officials said in an early support document that iPads and iPhones use rechargeable lithium-ion batteries that can be repeatedly charged and discharged over the life of the battery. If the battery is fully charged for a long time, the battery health will indeed be affected.
However, in this case, Apple officially stated that it provides a charging management function in the system. Because sometimes iPhones and iPads have to be connected to a power source for extended periods of time (such as when the device is used for a display or a point-of-sale system), this feature helps keep the device‘s battery healthy.
It‘s important to note that charge management is available on iPads with iOS 11.3 or later, and iPhone XS, iPhone XS Max, or iPhone XR models with iOS 12 or later. Since this is an early document, Apple officials have not yet mentioned whether subsequent iPhone models also have this function, but as the device continues to update, the function should continue.
This feature monitors whether these devices are used under the above charging conditions and reduces the maximum battery capacity as needed. The battery indicator shows the percentage of charge based on the adjusted maximum capacity. When the iPad or iPhone is no longer connected to a power source for an extended period of time, and conditions and battery health allow, the maximum battery capacity will return to its pre-regulated level.
That is, if your device meets the above conditions, you may find that the maximum battery capacity is reduced when the device is charged for a long time. When the device is no longer connected to a power source for an extended period of time, the maximum battery capacity returns to normal.
So don‘t worry. It won‘t matter too much if you forget to unplug the device from the power source for a while. Moreover, for existing models, the iPhone and iPad itself will stop charging when fully charged, which is also a kind of charging protection.
