The introduction of vapor chamber on iPhones it dates back to just one generation ago, but Apple has already made important improvements to its implementation. According to a new test conducted by Geekerwanthe iPhone 18 Pro Max indeed manages to maintain lower temperatures than some Android smartphones with larger cooling systemswhile reaching similar power limits.
To evaluate the effectiveness of the dissipation system, Geekerwan used different thermal sensors on the iPhone 18 Pro Max and on some competitors. The confrontation involved OnePlus 15, iPhone 17 Pro Max and iQOO 15 Ultra. The Android smartphones used in the test were equipped with Qualcomm Snapdragon 8 Elite Gen 5while successors with Snapdragon 8 Elite Gen 6 Pro could achieve different results.
In the test, the iPhone 18 Pro Max hit a power cap of 5.9Whigher than the 5.4 W recorded by the iPhone 17 Pro Max. Despite the higher power limit, the new model reached a temperature of 44.3°Cwhile the previous iPhone 17 Pro Max stopped at 45.2 °C. The result therefore highlights an improvement compared to the previous generation in the test conditions.
The comparison of the dissipation of iPhone 18 Pro Max with other Android smartphones
The value of the iPhone 18 Pro Max is also close to that of the OnePlus 15which reached a power limit of 6.1 W. In this case, however, the Android smartphone recorded a higher temperature, equal to 47.2 °C. The comparison therefore shows similar power values, accompanied by different temperatures in the devices tested.
Particular attention was paid toiQOO 15 Ultraequipped with a dedicated cooling fan. With the fan turned off, the smartphone has reached a limit of power of 5.9 Widentical to that of the iPhone 18 Pro Max, but with a temperature of 47.2°C. By activating the fan at maximum speed, the limit instead rose to 7.3 W and the temperature dropped slightly to 46.2°C.
According to the test results, therefore, the iPhone 18 Pro Max succeeds combine a power limit close to that of some Android gaming smartphones with a lower temperaturewithout using a dedicated fan. The result is attributed to the efficiency of the SoC and the cooling system adopted by Apple, while it should be considered that the results of future devices with Snapdragon 8 Elite Gen 6 Pro they could be different.
