The iPhone 15 Pro is poised to be a formidable device, but it appears that there is a potential downside: overheating. Recent reports indicate that the A17 Pro chip, produced by TSMC, which powers the phone, is susceptible to overheating even under regular usage.
All You Need to Know about iPhone 15 Pro Heating Issue
This A17 Pro chip stands out as Apple’s and, in fact, the world’s inaugural 3nm chip. While this development contributes to enhanced performance, it seems to be causing the chip to run hot. Back in March, an informant named Revegnus tweeted that TSMC was encountering challenges with the 3nm manufacturing process, possibly leading Apple to relax its standards for the A17 Pro chip. This suggests that some chips that would have been rejected may have been accepted.
Revegnus has also recently shared a heat map of the iPhone 15 Pro, revealing that the area surrounding the A17 Pro chipset is unsurprisingly the hottest, with temperatures reaching as high as 48 degrees Celsius or 118.4 degrees Fahrenheit.
Popular YouTuber Vadim Yuryev believes that Apple might have increased the A17 Pro chip’s power consumption to achieve the desired benchmark results. However, this increase in power usage could result in reduced battery life and quicker heat buildup in the phone.
Due to its tendency to heat up rapidly, the iPhone 15 Pro eventually engages in performance throttling to safeguard its internal components. Moreover, the device can become hot enough, up to 118.4 degrees Fahrenheit, to cause first-degree burns, which is concerning, given that the iPhone 15 Pro lacks a cooling solution.
In a review, TechTablets confirmed that the iPhone 15 Pro Max’s A17 Pro chip experiences significant throttling. In just 2 minutes of use, it lost nearly 25% of its performance, and after 20 minutes of GPU-intensive tasks, performance had dropped by nearly 34%. However, it’s worth noting that the benchmark scores remain quite impressive for a mobile chipset.
