3 Steps to Cool Down Your iPhone Immediately
Most of the time, it’s normal for your iPhone to heat up during charging. It happens due to chemical reactions that occur in the battery. However, the safe limit for your iPhone is between 32º to 95ºF (0º and 35ºC), according to Apple.
So, if your iPhone goes above 95ºF or 35ºC during charging, you may see this message.
As shown, your iPhone will stop charging until the temperature lowers. This will reduce the heat generated by the device, but it may take a while. If you want to quicken the process, follow these steps.
- Step 1: Unplug your iPhone and turn it off.
- Step 2: Move it to a cool, covered place away from direct sunlight.
- Step 3: If possible, remove the case and provide extra airflow using a fan.
After a few minutes, once your iPhone has cooled down, you can safely turn it back on and retry charging. If it heats up again, go through the next section to find out why your iPhone may be overheating during charging and how to fix it.
Reasons Your iPhone is Overheating When Charging
There can be many reasons why your iPhone is overheating when you charge it. Once you know the root cause of the issue, it becomes easier to fix it.
Here are five of the most common causes along with corresponding fixes.
1. Counterfeit Cable and Adapter

If the battery health is significantly degraded, it might be time for a battery replacement. Check the FAQs section below for more details on how to replace your iPhone battery.
3. Dust Buildup in Charging Port
If there is dust inside the charging port, it could obstruct the cable pins and block the connection. If you see any dirt lodged in the charging port, use a soft-bristled brush or plastic toothpick to remove it. Watch this video to learn more:
After that, try charging your iPhone again.
4. Hot Environment
As mentioned before, direct sunlight was the reason my iPhone 13 overheated when charging. However, any external heat source can lead to overheating as well.
So, avoid placing your iPhone in direct sunlight or a car on a hot day for an extended time. Instead, place it in a cool room with moderate airflow. It can also help to remove your case if it is blocking airflow and trapping heat.
5. Heavy Background Processes
It’s normal for your iPhone to be warm when charging. However, if there are many background processes running during charging, it can lead to overheating as well.
To avoid this, close all non-essential background apps. If you want to go a step further, open Settings, go to General, and Background App Refresh. Here, select Background App Refresh and tap Off.
In addition, once your iPhone has reached a normal temperature, update iOS and all your apps. Apple and app developers frequently release software updates that can include bug fixes and optimizations to help prevent overheating issues.
