iPhone 13 heating after 16.0.3

Hi Panirajasrikanth,

We'd love to provide some great tips and helpful information regarding your device temperature. First, there are many different factors that can cause the device to heat up. They are listed below.

Your device might get warm

"You might notice that your device feels warmer when you:

• Set up your device the first time
• Restore from a backup
• Wirelessly charge your device
• Use graphics-intensive or processor-intensive apps, games, or features, including augmented-reality apps
• Stream high-quality video

These conditions are normal, and your device will return to a regular temperature when the process is complete or when you finish your activity. If your device doesn't display a temperature warning, you can keep using your device."

If your device gets too warm, then you can follow the tips below to resolve the issue.

If your device gets too warm

"iOS and iPadOS devices have built-in protections to prevent overheating. If the interior temperature of your device exceeds the normal operating range, your device will protect its internal components by attempting to regulate its temperature. Here are some of the higher ambient-temperature conditions and activities to avoid, because they might cause your device to change performance and behavior:

• Avoid leaving your device in a car on a hot day.
• Avoid leaving your device in direct sunlight for an extended period of time.
• Avoid using certain features in hot conditions or direct sunlight for an extended period of time, such as GPS tracking or navigation in a car, playing a graphics-intensive game, or using augmented-reality apps.

If the interior temperature of your device exceeds the normal operating range, you might notice these changes:

• Charging, including wireless charging, slows or stops.
• The display dims or goes black.
• Cellular radios enter a low-power state. The signal might weaken during this time.
• The camera flash is temporarily disabled.
• Performance slows with graphics-intensive or augmented-reality apps or features.

Additionally, if you're navigating, your device might show this alert and turn off the display: "Temperature: iPhone needs to cool down." Navigation still provides audible turn-by-turn directions. When approaching a turn, the display will illuminate to guide you through the turn."

Yes I’ve been having this issue too on a 12pro. It doesn’t get crazy hot but it’s almost always warm to the touch now. I reset my phone thinking that would help but no luck. Was thinking of loading the beta but I’m reading of overnight phone restarts with the current build. It’s annoying because the battery drains crazy fast.

iPhone 11 Pro with all the apps terminated, phone plugged in fully charged, minimum screen brightness and just showing the home screen without any widgets and clear of any app icons, I see the process SpringBoard constantly going at 100% CPU and its making my phone real hot. Of course, it's not like burning my hand, but it's to a point where it is definitely concerning. This never happened before, now it seems like its happening all the time since the update to 16.0.3?
