iPhone 15 Pro Max reportedly faces serious overheating issues

The iPhone 15 Pro appears to be an impressive piece of technology, boasting immense power. However, this might not be without its challenges. There have been emerging concerns regarding its tendency to overheat. Central to this issue is the phone’s A17 Pro chip, a product from TSMC. This chip holds the distinction of being the world's premier 3nm chip. While this small size contributes to an enhanced performance, it's suspected of making the chip susceptible to overheating.

A few months ago, there were indications that TSMC was encountering difficulties with this 3nm process. As a consequence, Apple may have had to adjust its quality benchmarks for the A17 Pro chip. There's a possibility that chips, which under normal circumstances might have been deemed unsatisfactory, were given approval.

Supporting these concerns, a recent heatmap of the iPhone 15 Pro has pinpointed the region surrounding the A17 Pro chipset as being particularly prone to high temperatures, at times reaching up to 48 degrees Celsius (or 118.4 degrees Fahrenheit).

Further insight comes from Vadim Yuryev, a Youtuber, who postulates that Apple might have amplified the wattage of the A17 Pro chip to secure desired benchmark outcomes. Such an augmentation in power use could not only expedite the phone's heating but might also negatively impact the battery longevity.

These heating issues have consequential implications. When the iPhone 15 Pro gets too hot, it takes measures to reduce its performance to safeguard its internal components from potential damage. More worryingly, with the capability of reaching temperatures as high as 118.4 degrees Fahrenheit, there’s a risk of users experiencing first-degree burns, especially given that the iPhone 15 Pro lacks an inbuilt cooling mechanism.

Confirming these concerns, TechTablets, a reviewer, acknowledged pronounced throttling with the iPhone 15 Pro Max’s A17 Pro. Within a mere two minutes, there was a performance reduction of nearly 25%. After a 20-minute GPU load, the decline was almost 34%, though it’s worthy to note that despite this, the benchmark results are quite remarkable for a mobile chipset.

In summary, while the iPhone 15 Pro may be a powerhouse in terms of performance, potential users might have to grapple with issues related to overheating and performance throttling. Prospective buyers are advised to keep an eye on additional reviews to better understand the real-world implications of these issues on the device's performance.
