If you notice that your iPhone is getting hotter than usual while charging, it’s important to take precautions to prevent any potential risks to the battery and the device itself. Here are some recommendations to help you avoid this situation:
If you use the iPhone while charging, turn down the brightness of the screen
Using an iPhone with the screen brightness set to maximum for extended periods of time can contribute to the device heating up. Similarly, when charging the battery, the device may generate additional heat. If you find that your iPhone is getting excessively hot while charging, it is advisable to take the following steps:
1. Reduce the screen brightness: Lowering the brightness level of your iPhone’s screen will help reduce the heat emitted by the device. This adjustment can also ensure that the charging process continues uninterrupted, as high temperatures can sometimes cause charging to be halted.
2. Optimize ventilation: Ensure that the iPhone is not obstructed or covered by any objects while charging. Allow for proper airflow around the device to dissipate heat effectively.
3. Disconnect unnecessary accessories: If you have any unnecessary accessories connected to your iPhone while charging, consider disconnecting them. Accessories such as external speakers or game controllers can contribute to additional heat generation.
By implementing these measures, you can help prevent excessive heating during the charging process and safeguard the overall performance and longevity of your iPhone.
Disconnect wireless connections
Using an iPhone with maximum screen brightness can indeed contribute to heating. Additionally, if you charge the iPhone from a low battery level while having multiple connections active, such as Bluetooth, Wi-Fi, and mobile data, it can occasionally lead to overheating.
To prevent excessive heat buildup and ensure a safe charging process, it is recommended to minimize the number of active connections and reduce the screen brightness. By doing so, you can help maintain a lower temperature and allow the charging process to proceed smoothly.
Consider disabling unnecessary connections such as Bluetooth and reducing the screen brightness to a comfortable level. This will help prevent the iPhone from generating excess heat and ensure a safer charging experience.
Use official or MFi cables and chargers
While many Lightning cables and wall chargers may appear similar, not all of them are suitable for providing the optimal charging power for iPhones. Apple, like other manufacturers, has its own fast and optimized charging technologies. To prevent your smartphone from overheating, it is important to use compatible components.
It’s worth noting that you don’t necessarily need to use Apple-branded cables and chargers. The MFi (Made for iPhone) protocol allows third-party companies to manufacture accessories that meet Apple’s standards and ensure proper functionality, including during the charging process. These accessories may not carry the Apple brand, but they incorporate the necessary technology to provide reliable performance.
To avoid potential overheating issues, consider using MFi-certified cables and chargers from reputable brands. This will help ensure the compatibility and safety of the charging process for your iPhone.
Make sure your iPhone has fast charging
Fast charging has become a standard feature in many smartphones, but older iPhone models do not have this capability by default. Therefore, it is crucial to determine whether your specific iPhone model is compatible with fast charging if you want to charge the battery more quickly and safely. The following iPhone models support fast charging:
- iPhone 8 / 8 Plus
- iPhone X
- iPhone XS / XS Max
- iPhone XR
- iPhone 11 family
- iPhone 12 family
- iPhone 13 family
- iPhone 14 family
By using the recommended power for charging iPhone batteries, which is approximately 20W, we can avoid putting unnecessary stress on the battery, which could lead to faster wear and degradation over time. It is important to note that using a wall charger with a higher power output than recommended can result in the iPhone being unable to efficiently handle the excess energy, leading to heat dissipation and potentially affecting the overall performance of the device.
