iPhone 13 pro Overheating after 18.3.1 iOS Update

"iPhone 13 pro Overheating after 18.3.1 iOS Update: I have an Iphone 13 Pro . After updated it to iOS 18.3.1 the phone begun to drain the battery very quickly. With iOS 18.3.1 I finish the day with 50% charge, and now 7% (the use did not change). Also note that the Phone is warmer sometimes. How can I fix the problem ?"

Report this to Apple...

iPhone battery overheating and draining are well-known issues of iOS updates. Question is: "Just how many people have actually reported this to Apple?"

So, do your Part: Provide Apple with feedback on this, letting them know about this issue.  Apple may not get back to you directly, but the more feedback they receive on this, the more they will know what is occurring, and what bug fixes to include in updates to come. Apple will know nothing of this, if you don't report it to them.

1. Go Here: Feedback - iPhone - Apple
2. Select: "Bug Report" for the "Feedback Type"
3. Comment: that this all began after installing an update. Include the URL of this thread
4. Proceed from there as necessary

Let’s define “overheating”. If an iPhone overheats it shuts down so it can’t be used, and displays a message saying it must cool down before it can be turned on, and it will probably be unusable for an hour or so. If you are seeing this it is a hardware problem and you should contact Apple support: 

• Click on “Support” at the top of this page
• Go to Contact Official Apple Support

Note that both of the above have options to receive a callback or chat

If you are not seeing this your phone has not overheated. However, if you fast charge your iPhone it may get very warm, and may pause charging at 80% and display a message saying that charging has paused, and will resume when the phone cools down. This is NOT overheating, and is normal when fast charging. It also won’t prevent you from using any app you have on your phone.

Some apps that use a lot of energy or that use cellular data rather than Wi-Fi can cause the phone to run warmer. Worst offenders are Facebook, interactive games, watching streaming videos, and the Camera app. And having VPN installed, whether using it or not, can also consume a lot of energy.

All of these are manifestations of the 2nd Law of Thermodynamics.

Of course it does. Anything that uses energy gets warm.

If you have just updated allow a couple of days for iOS to complete its “housekeeping"
