📱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.

Before going to the extent of wiping your phone entirely and starting over again, realize that some activities such as charging or a lot of computational activity (e.g., video), generate heat. Some warmth is to be anticipated.* "Keep your iPhone, the power adapter, and any wireless charger in a well-ventilated area when in use or charging."** Read this article about keeping your iPhone, iPad, or iPod touch within acceptable operating temperatures - If your iPhone or iPad gets too hot or too cold - Apple Support


Changes in software such as upgrades may introduce new features which may add to power drain and heat generation. Check Settings > Battery to see if there are apps running that use a lot of power. If there are, decide if you can turn off a service such as Settings > General > Background app refresh when an app is in the background, or Settings > Privacy > Location Services. Read this support article to learn about the battery health feature —> iPhone battery and performance - Apple Support


If you think there is a problem with a device, have Apple inspect it. Go to this page to find your nearest Apple Authorized Service Provider (AASP) or Apple Authorized Distributor (AAD) --> Find Locations


How to make a Genius Bar appointment

1. Go to Genius Bar Reservation and Apple Support Options - Apple

2. Go to "Get hardware help".

3. Select your hardware and continue selecting options requiring replacing parts until you see "Bring in for Repair"

4. Sign in with your Apple ID

This is just basic electricity. The general public wants faster and faster charging. Very few iPhone users want it to take hours and hours to charge their battery.


How do you charge a battery faster? You apply more and more watts of charging power. Current iPhone 16 models can take 30 watts. But applying 30 watts will charge faster, but will generate a lot more heat.


iPhone users also want larger and larger battery capacity so they can use the device longer on a single charge. It now takes longer to fully charge larger batteries and the heat can’t dissipate as fast.


All this combines to produce more heat. This is just the reality of larger batteries and faster charging times. It’s just laws of physics and Apple, Google and Samsung aren’t changing them anytime soon.


The best thing you can do is place your iPhone on a cool surface to charge. Car seats, cushions, direct sunlight will insulate the device and retain heat, making the iPhone even hotter.


If lower operating temperatures are more important than fast charging, use lower wattage chargers.
