Some iPhone 18 Pro and iPhone 18 Pro Max users have reported that their phones get hot. Many have described heat during calls and charging, while others report noticeable warmth even during light use.
Users have reported trading in older models, like the iPhone 12 Pro, and not experiencing these issues with their previous devices. You might notice that your device feels warmer when you set up your device the first time, restore from a backup, complete a software update (particularly to a major release), wirelessly charge your device, use graphics-intensive or processor-intensive apps, games, or features, or stream high-quality video. These conditions are normal. For instance, one user noted that their iPhone 12 Pro never became uncomfortably hot during calls, but their iPhone 18 overheated after a 10-minute conversation, forcing them to end the call prematurely. Other users have shared similar experiences, highlighting a noticeable difference in thermal performance between the models.
If your device exceeds a certain temperature threshold, it will present a temperature warning screen. If your device doesn’t display a temperature warning, you can keep using your device. However, consistent heat issues can still be alarming, especially for a new device.
Insights in Settings > Battery inform you of activities happening in the background that can affect battery life and thermal performance for a while, such as Ongoing Device Setup (your device is completing setup steps in the background) or Ongoing iOS Update.
It is important to note that some activities, such as charging or performing computationally intensive tasks (e.g., video editing or gaming), can generate heat. Apple says these conditions are normal. Apple advises keeping the iPhone, power adapter, and any wireless charger in a well-ventilated area when in use or charging. Don’t sleep on a device, power adapter, or wireless charger, or place them under a blanket, pillow, or your body, when it’s connected to a power source.
After an update, certain tasks related to the update continue in the background and might affect battery life and thermal performance. Checking Settings > Battery can help identify apps that have used the most battery. You can also turn on Low Power Mode, which reduces the amount of power that your device uses by reducing or disabling certain settings and features, like Mail fetch, Hey Siri, Background App Refresh, and some visual effects.
For new devices, initial setup and background activities may cause temporary heat generation. Your device will cool when the process is complete or when you finish your activity.
