iPhone Temperature Notice

It’s entirely possible that moisture worked its way into the phone.

Make an appointment at the Genius Bar of your local Apple Store and have it checked. If the liquid contact indicators have been tripped, the phone will have to be replaced. Liquid damage is not repairable.

It’s also possible that the timing is just coincidence and the temperature fault has nothing to do with the liquid.

Hi Alex

Very Unlikely to have moisture damage! You can stick it under water (6 meters) for 30 minutes. IP68 rated. I still won't recommend you test this, but splashes and a few drops into shallow water hasn't killed my 13+. Look at all the stories about iPhones lost in oceans, lakes and rivers for months and they still work fine. Seriously folks, modern iPhones can handle minor water encounters just fine.

I think it was due to some iPhone internal processing going on.

Have you tried shutting down the phone, wait a minute or two then restart phone? It might be possible that some process has become corrupted, so shutting down (Power off) may clear the problem. Shutting down and restarting an iPhone is good place to start troubleshooting problems.

Did you recently update the iOS? If you have automatic updates on, then your phone may have updated. After updates, iPhones do this massive local on board analysis of various apps like photos and data that often causes CPU activity for short intensive time periods. This can cause overheating. Try leaving phone charging overnight, it might complete the processes.

A new issue is wireless charging. They do create heat so check while charging after about 15 minutes. Charging via cable is faster and produces less heat.

Having silicone cases on your phone can contribute to overheating as well as direct sunlight, heat source etc…

Hopefully, by now your phone is fine, but if not and you continue with overheating, time for Apple Store.

Hope this Helps, Greg

Hi KiltedTim

Please don't shout.

AFAIK overheating is more likely caused by the issues I stated. It is more likely related to a software or hardware processor or environmental heat issue than water penetration.

Apple tests and rates their iPhones 13 series as IP68. In fact, Apple rates this product to a depth of 6 meters instead of the standard 1 meter.

iPhone 13 - Technical Specifications - Apple

So while we can discuss the technical aspects of the IP68 rating, I merely am using this rating to suggest the latest iPhones have a engineering quality to withstand accidental water contact.

Is it possible to be related to a water splash, well maybe, there are indeed threads right here on Apple discussions. Most of these report a water warning not temperature.

Yep could happen, or as you posted "It’s also possible that the timing is just coincidence and the temperature fault has nothing to do with the liquid."

Just for fun, go on YT and look at the thousands of videos of recovered iPhones from water and the torture tests done for water immersion.

I watched a woman at the ocean using her iPhone 13 Pro naked (no case) to film the surf including repeatedly going through/under incoming waves. She said she did it often and no problems.

Having said all this,

Apple does not cover water damage!

Try not to drop your phone into water.

Hope this Helps, Greg

oops sorry for the loud warning!

This is ABSOLUTELY FALSE.

That's not how water resistance ratings work.

I wouldn't have to if you didn't post blatantly false information.
