I phone temperature issue after updating ios27

📱Facing iPhone heating issues? Here's what worked for me on my iPhone:

1️⃣ Backup on iCloud/iTunes

2️⃣ Log out of Apple ID

3️⃣ Erase (Keep eSIM Data)

❌ DO NOT restore from backups! Set up as new iPhone. Wait 2-3 days - no issue! That Indicates...

✅ No hardware/ iOS issue

Now...

📦 Restore data gradually

🔍 Find app/settings causing heat

My experience says this is purely caused by some third-party app that you may have installed.

I am not aware of the ambient temperature in which you are using the iPhone. However --> Keeping iPhone, iPad, and iPod touch within acceptable ...

Store the device where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave the device in your car, because temperatures in parked cars can exceed this range.

Use iOS devices where the ambient temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might cause the device to change its behavior to regulate its temperature. Using an iOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could cause the device to turn off. Battery life will return to normal when you bring the device back to higher ambient temperatures. Using an iOS device in very hot conditions can permanently shorten battery life.

Welcome and thank you for reaching out. 🤗

It is normal for an iPhone to run warmer than usual for a day or two after a major iOS update due to background processes like indexing.

However, if the issue persists, there are several steps you can take to resolve it:

• Wait it out — Background tasks like photo indexing and data syncing can cause the phone to heat up temporarily after an update.
• Update your apps — Third-party apps may need updates to run efficiently on the new iOS version. Check the App Store for any available updates.
• Check your charger — Using a high-wattage charger can cause the phone to heat up. Try using a standard 20W charger or a different power source.
• Remove the case — Some cases can trap heat and prevent the phone from cooling down properly.
• Enable Low Power Mode — This reduces background activity and can help lower the phone's temperature.

If your iPhone continues to overheat, you may want to contact Apple Support for further assistance.

Good Luck! 👋🏼😉

Although I don’t disagree with your logic, I’m having the same issue and it didn’t start until I got the update. I’ve only been in my car for ~20 minutes, and it’s not that hot outside. My phone shouldn’t be so hot that charging paused.

Charging paused is NOT the same as overheating. Charging paused is a normal feature of iPhone now and was actually introduced with iOS 26. If you're using your phone and charging it at the same time, you're pushing it harder and charging will pause to ensure the phone doesn't overheat and you'll see this notification. This is not an issue you should be concerned with.

It’s because of the indexing and such post upgrade not a rogue app and the heat issues post upgrade are very common. The same happened on the initial release of Apple Intelligence (which I turned off and heat issues immediately stopped). Maybe that’s the bad app you are speaking of.

What is your Battery Health percentage when viewed at Settings > Battery > Battery Health, and the Charge Cycles?

Not every issue an individual encounters on their device can be attributed to an iOS update. If the update itself were the root cause, then every device running that same version of iOS would exhibit the identical problem. In such a scenario, the forums would be flooded with countless posts reporting the same malfunction, creating an unmistakable wave of complaints that no one could possibly overlook. The absence of such widespread reports strongly indicates that the issue is not systemic, but rather specific to the device in question.

• Are you referring to the charging paused due to heat notification or the actual temperature warning on the screen where the thermometer is displayed?

It's been months since I've updated my iphone 14 pro max to IOS 27 beta. My phone showing the temperature issue wherein the phone needs go cool down before I can use it. I thought I just need the official IOS 27 to fix it, but until now that I have installed the official update of IOS 27, my phone keeps having temperature issue pop up even I am in cold place. Please help!

my iphone 15 just has be updated with the new ios 27 and everytime i try to do something on my phone afterwards it keeps turning itself off. and i get a emergency thing on my screen and I can't get back into my phone, so I have to restart turning my phone off and on. and I have been doing three times tonight. and my iphone is not even hot, i have updated my apps and done the apps refresh thing too. but nothing is working or stopping my iphone turning itself off. so can you please tell me what i should do or what you can do to fix it? like can i go back onto the old ios 26 instead or will you fix the problem with the new upgrade. or what else should i do? as i have tried everything like taking the cover off, unplug the charger etc. but still nothing is WORKING!! and I'm getting really annoyed
