[Real Answer] How to Fix iOS 18 Overheating After Update

Part 1. Why is My iPhone Heating Up after iOS 18/18.1 Update?

There are several reasons why your iPhone might be heating up after updating to the iOS 18:

Background app refresh: Following the update, your iPhone may be working hard to refresh apps in the background, causing the device to heat up. The new OS may also be indexing data and updating apps to ensure compatibility.

Buggy apps: Some apps might not be fully optimized for iOS 18 yet, causing them to consume more resources and generate excess heat. Buggy or poorly designed apps can also contribute to overheating.

Battery drain: If your iPhone's battery is draining faster than usual after the update, it may indicate that the device is working harder, leading to increased heat output.

Overworked processor: The update process itself and the tasks your iPhone performs immediately after updating, such as reindexing data and recalibrating settings, can put a strain on the processor, causing it to heat up.
