Apple has made a significant change in cooling technology with its new flagship iPhone 18 Pro Max. The cooling performance offered by the device iPhone 18 Pro Max is particularly impressive in intensive usage scenarios.

Extensive thermal tests conducted by YouTuber Geekerwan reveal the efficiency of Apple’s new vapor chamber system. In these tests, the device is supported by the A20 Pro processor on the hardware side.

Key Data from Thermal Tests

The test process compares the iPhone 18 Pro Max model with the OnePlus 15, iQOO 15 Ultra, and the previous generation iPhone 17 Pro Max. All Android devices are equipped with the Snapdragon 8 Elite Gen 5 processor.

According to the data obtained, the iPhone 18 Pro Max manages to maintain a temperature of 44.3°C while reaching a power limit of 5.9W. Last year’s model, the iPhone 17 Pro Max, reached a temperature of 45.2°C at a power limit of 5.4W.

The OnePlus 15 model, despite reaching a power limit of 6.1W in the tests, heats up more than the iPhone 18 Pro Max with a temperature of 47.2°C. This shows how effective Apple’s new vapor chamber design is in thermal management.

The iQOO 15 Ultra model operates at the same power limit of 5.9W as the iPhone 18 Pro Max with the external cooling fan off. However, this device reaches a higher temperature of 47.2°C at the same power level.

Fan Support and Cooling Engineering

The iQOO 15 Ultra can increase its power limit to 7.3W when the external cooling fan is running at maximum speed. Although the device’s temperature drops to 46.2°C with fan support, the passive cooling performance of the iPhone 18 Pro Max is still quite impressive.

Apple manages to achieve comparable efficiency stability without needing any external cooling fan. This is directly related to the efficiency of the A20 Pro processor and the engineering work in the device’s internal design.

It is predicted that new generation processors such as the Snapdragon 8 Elite Gen 6 Pro will yield even better results in the future. However, current data proves that the iPhone 18 Pro Max is competing head-to-head with its rivals in its class.

The thermal management of a device directly affects user experience, especially during long gaming sessions or processes requiring high performance. Apple’s improvements in this area promise more stable performance in the portable gaming world.

Test results clearly show how hardware and software optimization, combined with the cooling system, makes a difference. Although Apple is not using vapor chamber technology for the first time, the application in this generation appears to be quite successful.

This detailed analysis by Geekerwan provides a valuable resource for understanding the thermal limits of portable devices. Do you think passive cooling systems in smartphones can provide sufficient performance without the need for external fans?
