If you experience excessive heat while charging your iPhone‘s battery, we have some valuable recommendations to share with you. This post will not only provide useful tips to address this issue but also highlight the risk factors that can cause your phone’s temperature to rise abnormally. By following these guidelines, you can ensure the well-being of your device and maintain its optimal health.
The iPhone can get hot for various reasons
Selecting an appropriate charger for your iPhone is crucial. Opting for a charger solely based on its power capacity may not necessarily result in faster charging. Fast charging often leads to the selection of the quickest and most powerful adapters. However, this approach can have counterproductive effects as the iPhone cannot efficiently retain all the energy delivered by the charger. Consequently, excess energy is dissipated in the form of heat, which is transferred to the phone itself, leading to battery and component overheating. To mitigate this, it is advisable to utilize adapters with a power output of around 20W for iPhones that support fast charging.
There is a specific scenario where overheating may occur: using the iPhone while it is charging. If the usage is not demanding, the device should not heat up excessively. However, simultaneously running multiple applications at maximum brightness can cause a temperature increase. To address this, it is recommended to reduce the screen brightness when not using resource-intensive applications such as FaceTime video calls, screen sharing, or running multiple apps simultaneously. In such cases, the likelihood of the iPhone overheating is higher.
If our battery health is no longer at 100% due to its gradual decline over time, and we are at a very low battery percentage, it can also lead to overheating. This situation is more likely in iPhones that have been in use for an extended period without the battery being replaced. When the battery level is very low, the charging process can exert more strain than under normal conditions, resulting in increased heat generation. Therefore, if we frequently encounter this issue, it can be beneficial to reduce the power output of the charging adapter to deliver less energy simultaneously.
Another effective method to prevent excessive heating is to utilize official or MFi certified power adapters and cables. Although it may seem like a minor detail, using components that are not optimized for iPhones can lead to an energy delivery method that is not aligned with the specific requirements of the device. Charging our iPhone with an unofficial or non-MFi certified adapter may result in suboptimal charging performance tailored to a different device.
