iPhone 15 Pro overheating after iOS update to 17.3

This 17.3 update caused my iphone 13 to be completely unusable! Battery hot, no reaction, not even able to reboot. Had to wait until battery was empty. The iphone is still slow and does not behave like before the update. Apple, why do you deliver such extraordinary bad quality? I‘m p….d off with Apple quality and how you as a company communicate and treat your customers.

The Update 17.3.1 has seriously messed up the volume of my phone. When it rings I can hardly hear it. Two of my friends have said the same thing had happen after they updated theirs too . What’s going on?

After the newest iPhone update my phone overheats really fast, my battery drains quickly, my WiFi has a hard time staying connected, my audio on phone calls and video calls waves in and out all the time. I wish I could uninstall the update!! Really hope they fix these problems soon!!

iOS 15

• After updating to iOS 15, my iPhone 11 Pro Max’s speakers didn’t worked anymore. Also my phone is heating even when I’m not using it, therefore battery life is reducing fast.

iOS 13

• Yes, I've got into a pickle with this heat problem too. 13.3.1 was fine (for iOS13) but then came 13.5 and boom the heat started. From there I quickly went back to 13.4 and no joy. I then downloaded 13.5.1 and still no joy. When 13.6 arrived I jumped on it, what did I have to lose. After two days it started heating up again, bugger. It was then I thought I might as well jump on the iOS14 Beta program. The first beta was pretty bad but I waited and Beta 3 was better. We still had heat...

• Agree. Let’s create some new emojis and other trivial things over fixing the freezing and heating up issues caused by IOS13. I never had these issues on IOS12. I have advised Apple that my phone gets extremely hot causing me to remove from my person because it burns my skin. If it heats up to the point that something else occurs the look out. As I said I parted with my hard earned for this phone and to put up with this for several months. Please make rectifying this a priority other...

iTunes said it was restoring to factory settings, but if it did so to clear the device, it then went on to restore it from my computer with the local backup. The apps seemed to take about an hour to fully reload. Most of the data was restored. The only "loss" was the recently used contacts that show in my share options for websites, and the "commonly used" websites. AFAIK, no contact losses based on perusing known recent additions.

So it did do the full restore without any additional help from me. *breathes huge sigh of relief*. My wife who has an Android phone was saying this should be a good reason to abandon Apple. I would but for a large curated iTunes library that, so far, I have not found a way to port to Windows so that an Android device can use it seamlessly. [But if/when that happens...]

So I have an iPhone X and out of nowhere today it started to go crazy with delayed screen touch and apps not working. Then it started to go to a black reboot screen and got extremely hot. Also wouldn’t charge and at one point went from 50% battery to zero and shut off and back on really fast with 30% battery. So long story made short, I turned off wifi and took out the SIM card. Then I was able to turn phone off and back on, waited about ten minutes, put SIM card back in and turned it on, then did a reset on everything. Now it works better than ever. Down side is you have to re log into apps and bank stuff, took me about 2 1/2 hours but in my opinion, worth it. But time will tell if I’m out of the woods, I wish you the best of luck.

📱Facing iPhone heating issues? Here's what worked for me on my iPhone 12 Pro:

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.

If your iPhone or iPad gets too hot or too cold - Apple Support

Restart the phone.

If that doesn't resolve it, Reset All Settings. The link below tells you what that resets. It will not delete your apps or data within apps, as it doesn't erase the phone. It will remove your saved Wi-Fi connections, so make sure you know your Wi-Fi password to reconnect.

Return iPhone settings to their defaults - Apple Support

Have you added a third-party keyboard or any VPN apps?

Try resetting your network settings (This will remove saved Wi-Fi connections, so you'll need to know your Wi-Fi password to reconnect to it):

If your iPhone or iPad won't connect to a Wi-Fi network - Apple Support

"Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings."

my flash won’t turn on after the update and I have an important camera message notification 😔

I had the same problem but after restoring it is much better.

I have a 13 pro, just updated to the 17.3.1 system and all my “notes” in my Contacts are gone.. Any know how to get those back??

Ever since this update my phone has to be charged at least three times a day and at night without optimized charging I still only charge to about 50-86 percent. I turned it off and back on, I shut all open apps down and I even tried lower mode which while charging made it even worse!!! It would only charge to about 30 percent, I tried wireless charging as well but nothing is working, this new update has slowed my phone down incredibly like it’s in VPN mode or if it’s running a background hidden app

i brought my new iPhone 15 pro in January 20 2024 and i also installed the latest iOS update it’s heating like a crazy it’s worse than my old iPhone 12 Pro Max and the battery draning fast too so APPLE PLEASE FIX IT FASTLY
