## **There are a number of reasons why an iPhone may not charge to 100% of its battery capacity, possibly due to issues with the charger, optimized cable or power adapter, dust on the Lightning port, or battery temperature.* * If iPhone does not charge to 100%, it is recommended that users first check if optimized charging is enabled, and if there is a problem with the cable or charger. If all is well, there may be a problem with the iPhone’s battery or hardware. In that case, it is best for the user to contact Apple support for help. Optimized Battery Charging is a feature that is enabled by default after a user sets up an iPhone or updates to iOS 13 or later. This feature reduces battery consumption by limiting the charge to 80% when iPhone detects that it will be connected to a power source for an extended period of time. To turn off Optimized Battery Charging, go to Settings > Battery > Battery Health & Charge and turn off Optimized Battery Charging. If you’re having issues with your cable or charger, make sure they’re in good condition and compatible with your iPhone. Users can try plugging their iPhone into a different USB port or charger to see if that solves the problem. During the summer, it’s not surprising that iPhones reach high temperatures that cause the phone to stop charging, especially if the user is using the phone while it’s charging (for example, when using CarPlay in a car). If after checking all of the above, the iPhone is still not charging to 100%, then there may be a problem with the battery or hardware.
