iPhone 15 overheating

I'm sorry to hear that your iPhone 15 is overheating. Overheating can be caused by various factors, such as running resource-intensive apps, high ambient temperatures, or a malfunctioning component. To address this issue:

1. Close any background apps: Make sure you're not running too many apps simultaneously.

2. Check for software updates: Ensure your iOS is up to date, as updates may include bug fixes.

3. Remove your phone case: A thick case can trap heat, so consider removing it.

4. Avoid direct sunlight: Keep your iPhone out of direct sunlight.

5. Restart your iPhone: A simple restart can sometimes resolve overheating issues.

6. Reset settings: You can try resetting all settings in the "Settings" app.

7. Monitor battery health: In "Settings" > "Battery" > "Battery Health," check the maximum capacity. If it's significantly degraded, it might be contributing to the issue.

If the problem persists, consider contacting Apple Support or visiting an Apple Store for further assistance.

iPhone 15 Pro Max.

Replying here after 1 Month of use - after the 17.0.3 update my phone is fine. It's also fine with iOS 17.1 - I have been using the phone normally, and have not seen any unusual heating, warming, or battery use anymore.

In fact battery life is stellar and I usually go to bed at night with around 50% battery remaining.

In hindsight I believe there was a bug that was fixed with 17.0.3 (and also in subsequent OS releases)

Also add the fact that when we set up a new iPhone from iCloud backup, it works very hard downloading and installing all apps from the app store, indexing all files for spotlight, indexing all photos, running photo recognition on my roughly 20,000 photos, and so on - it does a lot of stuff in the beginning.

So give it 1-2 days, upgrade to 17.1 if you haven't, and then see.

Restoring from backup is an awkward phase of high CPU use for the first few days, especially if you're like me and always sleep with airplane mode on, meaning the phone can't do most of its work at night either.

Did you update your brand new iPhone to iOS 17.1. And Apple suggests that over the first few days while it is indexing the billions of bytes of data over to the new phone it will run warmer. You need to let it do its thing over the next few days, update it to the latest iOS version and then if after a few days it's still too warm, schedule an appointment at your Apple Store Genius Bar. There is no design flaw.

After the first couple days, my iPhone 15 Pro Max calmed down and NEVER gets too warm.

Plug it in at night while it is on so it can do its setup things … wait around 2 weeks.

Mine overheated too in the beginning but it’s all normal now - it took around one week for things to settle down.

For example it was downloading 30,000 images and doing image recognition on all of them - this takes a long time and heats up the phone

and other tasks like that

There's nothing to fix. Apple specifically suggests that when you get a new iPhone, for the first few days it will run warmer than you might expect. It takes a few days for the phone to index the millions of bytes of data on a new iPhone. And if you are also using to do other tasks while it's indexing, it will definitely run warm to hot. After a couple days, it will settle down as expected.

If your new iPhone 15 Pro Max is getting hot, try a few simple things. First, update your phone to make sure it has the latest software. Next, stop apps you don't use from updating in the background. Also, check to see if any apps are using a lot of battery and try to use them less. Lowering your screen brightness and using location services less can also help. If it's still hot after trying these, you might want to reset your settings. I hope this will solve the problem.

They released iOS 17.0.3 just yesterday for this. If you haven't updated, do so. Then Force Restart your iPhone after the update.

Hello everyone,

i had the same problem (overheating and draining battery); i went to settings-> battery -> which app is using my battery the most, i found whatsapp business was the first one with background activities even having disabled this background app refrech in the app setting. So what i did? Simply, i deleted whatsapp business from

my iphone and that’s it… overheating disappeared so battery draining too. So, i advice you to see which is the big app using battery and delete it. This means app developers have a lot of work to do or apple must do something… hope i was helpful.

I had the same problem last two days but it’s perfect now on day 3. No heat and no battery loss.

Photos app seems to have consumed more battery implying iCloud restore of a large stash of photos and post restore optimisation seems to be the culprit I can think of.

My suggestion is give it some time. Try to do a hard reboot which seems to have helped.

I had the overheat message (not exact wording) on my screen 15 pro while iCloud downloaded. After completing iCloud download, I rebooted no issues. Cooler than 14 pro it replaced. 14 pro was very warm often although never received temperature message. 15 pro does not even get hot when charging barely warm. I hope the quick jerk reaction from Apple is not to throttle processor. It will be as bad as the fine woven cases. If so I have until 10/22 to exchange.

I’ve had the phone for less than 24 hours and in a silicone case. But I’ve noticed the heat gets REALLY intense when I’m watching videos on YouTube :/

It can take a couple days for the phone to finish indexing data and watching videos would naturally tax the battery in any phone. You need to give the phone time to do its internal housekeeping before you declare there is an issue.

I can't post the link but it also says...The report notes that some of these apps include Instagram, Uber, and the racing game Asphalt 9: Legends, and Apple is working with the developers of these apps to address the issue. The report adds that Instagram already introduced a fix as part of an update to the app released on Wednesday.

So now it makes sense

It's not the iphone hardware it's some apps that didn't get effective or no updates for IOS17 and IOS17 bug. If it was the design of the hardware all iphones 15 pro/pro max would overheat and that it's not happening, only a small part. Considering Apple sold over 24 millions units only for the iphone 14 pro ... I'd like to know how many iphone 15 pro have been pre-ordered, considering they are all sold out. If happened to me I'd restore my iphone as a new iphone do not use any back up, do not d/l any app and then try to see if it's overheating again. My iphone 15 pro 256GB is working perfectly no signs of getting warm. Consider that this is a worldwide community

Try removing Facebook as well and try with Apple apps only first. After all Facebook is in the same Meta family as Instagram and we know there is an issue with the latter.

Turn off background app refresh under settings.

Also enable 5G Auto. There were issues reported with 5G and eSIM.
