Latest update on iPhone 16 Pro overheating issue
Development of graphene cooling system for iPhone 16 series
Apple is reportedly developing a new graphene cooling system for the iPhone 16 series, which has far better thermal conductivity than the copper material used in current iPhone coolers, potentially allowing it to dissipate heat more effectively.
The iPhone 16 series may also feature a larger graphene sheet at the bottom of the device, which is expected to address potential overheating issues. This new cooling system may be optimized for the computational demands of AI, efficiently dissipating high power consumption (6W) and preventing components from overheating.
iPhone 16 Pro may get metal battery case
According to sources, the iPhone 16 Pro may have a metal battery case, which could further reduce overheating, and Apple is also reportedly planning to separate the onboard storage chip from the SoC (system-on-chip), which is expected to improve cooling.

Thermal throttling issues with initial release of A17 Pro chip
Thermal throttling is a technical measure that automatically limits the processing speed of your device to prevent it from overheating. This temporarily reduces performance to ensure safe operation of your device.
Before the launch of the iPhone 15 Pro, the A17 Pro chip was experiencing thermal throttling issues, causing some users to experience slower than expected performance issues. The issue was said to be caused by the difficulty of balancing the chip's high processing power with heat generation.
Currently, a software update for the iPhone 15 Pro has mostly resolved the thermal throttling issue with the A17 Pro chip. The latest iOS version brings thermal management and performance optimizations, allowing users to enjoy stable performance. This allows for smoother operation without the previous issues.
Additionally, hardware improvements to improve cooling performance are reportedly being considered, which is expected to result in more stable performance for users.

iPhone 15 heat prevention guide
Although the iPhone overheating situation has improved, it may still overheat when using energy-intensive applications. If overheating is still an issue, you can try the following solutions.
Steps to quickly cool down your iPhone
Stop using it
First, it's important to stop any applications or features that are using your iPhone and let your device rest, giving it time to cool down.
Keep the device in a cool place
Keep your iPhone in a cool place, out of direct sunlight. Keeping it away from hot environments will help reduce overheating.
Remove the case
Removing the case from your iPhone will allow heat to dissipate more quickly, especially when the phone is overheating.
Use Low Power Mode
By enabling "Low Power Mode" from Settings, you can limit your iPhone's performance and reduce heat generation.
Update to the latest version of iOS
The latest iOS versions often include improvements to heat and performance. Software updates can help reduce heat issues. Devices currently updated to iOS 17 are said to experience fewer heat issues.
