Latest update on iPhone 16 Pro heating issue
Development of graphene cooling system for iPhone 16 series
Apple is reportedly developing a new graphene cooling system for the iPhone 16 series. Graphene has much better thermal conductivity than the copper material used in current iPhone coolers, which could potentially 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 solve potential overheating issues. This new cooling system will be optimized for AI-driven computing demands and may be able to efficiently dissipate high power consumption (6W) and prevent components from overheating.
iPhone 16 Pro may get metal battery case
According to sources, the iPhone 16 Pro may add a metal battery case, which could further reduce overheating, and Apple is also said to be planning to separate the on-board storage chip from the SoC (system on a chip), which is expected to improve cooling.
Initial release of the A17 Pro chip encountered thermal throttling issues
Thermal throttling is a technological measure whereby your device automatically limits its processing speed to prevent overheating. This temporarily reduces performance to ensure your device operates safely.
Before the launch of the iPhone 15 Pro, the A17 Pro chip was suffering from thermal throttling issues, which caused some users to experience slower than expected performance on their devices. The issue was allegedly caused by the difficulty of balancing the chip's high processing power with heat generation.
Now, 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, ensuring users enjoy stable performance. This allows for smooth operation without being plagued by previous issues.
Additionally, hardware improvements to improve cooling performance are also reportedly under consideration, which is expected to allow users to enjoy more stable performance.
iPhone 15 heat control guide
Although the iPhone overheating situation has improved, it may still overheat when using applications that consume a lot of energy. If overheating is still an issue for you, you can try the following solutions.
Steps to quickly cool 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 the temperature.
Remove the case
Removing the case from your iPhone will allow heat to dissipate more quickly, especially when the device is overheating.
Use low power mode
By enabling "Low Power Mode" from Settings, you can limit your iPhone's performance and reduce heat.
Update to the latest version of iOS
The latest iOS version may include improvements regarding heat and performance. Updating the software may reduce heat issues. Devices currently updated to iOS 17 are said to experience reduced heat generation.

A smartphone case that improves the cooling performance of your iPhone
There are many different types of iPhone cases, but when choosing a case with a beautiful design, you may be tempted to prioritize appearance over performance. Cases that are particularly thick can reduce the cooling performance of your iPhone. For example, flip cases and leather cases can hinder heat dissipation.
If your current iPhone is an iPhone 16 or earlier series, NIMASO offers a variety of lightweight and thin smartphone cases.
NIMASO's iPhone 15 Pro case: Features include a tempered glass back and wireless charging support

1. Fully protected
NIMASO's iPhone 15 Pro tempered glass back case uses 9H hardness tempered glass on the back, providing strong protection from sharp objects such as coins and keys. The four corners are equipped with an air cushion structure to protect the device by softening the impact of a fall. In addition, it is designed to be 1.1mm higher than the LCD screen and 0.9mm higher than the camera lens, minimizing damage to the display and camera lens.
2. Excellent transparency and ultra-thin rear glass for efficient cooling
The back glass is ultra-thin and designed to not impair the beauty of the iPhone body while maintaining the protective performance of a clear case. This thin glass efficiently supports heat dissipation and improves the cooling performance of the device. It has an optimal balance of thinness and strength, providing solid protection while suppressing heat generation while complementing the design of the device.
3. Anti-yellowing and wireless charging compatible
Made of high-quality TPU material and specially treated to prevent oxidation, it is resistant to yellowing and maintains transparency for a long time. The sides of the case are made of soft TPU material, making it easy to put on and take off and preventing scratches. The precisely cut design ensures a perfect fit between the case and your smartphone, and it also supports wireless charging while still in place.
