Brand new iPhone 16 overheating during charging

I recently purchased a brand new iPhone 16, and I’ve noticed that it tends to overheat, especially during charging. The device becomes noticeably hot to the touch, sometimes uncomfortably so, even when using the original charger and cable. This happens even when the phone is idle or not running heavy apps during charging. I’m concerned this may affect the long-term performance or safety of the device.


Am I the only one?

📱Facing iPhone heating issues? Here's what worked for me.

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.
