The iPhone 15 Pro looks like a powerful device, but it may come at a price: overheating. New reports reveal that the chip of the TSMC-made A17 Pro phone is prone to overheating even with regular use.

The A17 Pro is Apple’s world’s first 3nm chip. While this improves performance, it also seems to cause the chip to overheat. Advisor revegnus In March, he tweeted that TSMC was experiencing problems with the 3nm process and that Apple may have lowered its standards for the A17 Pro chip as a result. This means Apple may have accepted chips that would otherwise have been rejected.

Revegnus also recently published a heatmap of the iPhone 15 Pro; This map shows that the area around the A17 Pro chipset is unsurprisingly the hottest, with temperatures reaching 48 degrees Celsius, or 118.4 degrees Fahrenheit.

Apple increased the power of the A17 Pro chip to achieve the desired test results, but this increased power consumption can shorten battery life and cause the phone to heat up faster.

Since the iPhone 15 Pro heats up very quickly, it slows down the performance of the phone over time to prevent damage to its internal components. Additionally, heating a phone to 118.4 degrees Fahrenheit is enough to cause a first-degree burn. This is especially worrying because the iPhone 15 Pro does not have a cooling system.
