iPhone 16 Pro Max Overheating During Camera Use After iOS 26.2 - Troubleshooting Steps Tried

I'm experiencing significant performance issues on my iPhone 16 Pro Max after updating to iOS 26.2 and would appreciate any troubleshooting suggestions from the community.

Device Information:

• iPhone 16 Pro Max (3 months old)
• iOS 26.2
• Battery Health: 100%
• Apple hardware diagnostics: Passed with no issues detected

Primary Issue - Camera Overheating:

When using the camera app, the device becomes extremely hot to touch within minutes and triggers a temperature warning. This occurs regardless of ambient temperature - I've tested in environments ranging from +1°C to +26°C with the same result. This issue has persisted for 3 weeks since the iOS 26.2 update. The overheating is accompanied by rapid battery drain during camera use. This did not occur prior to the iOS 26.2 update.

Additional Performance Issues:

• Overall system responsiveness has decreased noticeably
• Battery drains faster than expected given the 100% battery health status
• Performance was excellent before updating to iOS 26.2

Troubleshooting Steps Already Completed:

• Hard reset
• Cleared camera app cache
• Checked for background apps consuming resources
• Verified battery health in settings
• Reduced screen brightness
• Disabled location services temporarily for testing
• Tested in various ambient temperatures (+1°C to +26°C)
• Completed Apple Store hardware diagnostics (no defects found)

My Question:

Has anyone else noticed camera overheating with temperature warnings on iPhone 16 Pro Max specifically after iOS 26.2? Are there additional troubleshooting steps I should try before the next software update? Any insights would be appreciated.
