Apple launched its latest smartphone series, the iPhone 15 lineup earlier this month. The lineup includes four smartphones — iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max. The less-expensive iPhone 15 and iPhone 15 Plus features the A16 Bionic chipset which also powers last year’s iPhone 14 Pro models. Meanwhile, the iPhone 15 Pro models come powered by the latest A17 Pro chipsets which are based on TSMC’s 3nm architecture.
Apple has already started shipping the latest iPhones and some users have reported overheating issues with the Pro models.
According to a report by Medium.com, Apple analyst Ming Chi Kuo has claimed that the heating issues with the iPhone 15 Pro models are not related to TSMC’s 3nm node that was used for the A17 Pro chip.
What’s causing the heating issues in iPhone 15 Pro models
As per Kuo, the overheating issue could be caused by “compromises made in the thermal system design”. These compromises allowed Apple to cut down on the weight of the ‌iPhone 15 Pro‌ models. Kuo claims that the reduced heat dissipation area and titanium frame have negatively impacted the thermal efficiency of the devices.
How is it affecting users
Users reported that iPhone 15 Pro‌ models are becoming too hot to touch. Some tests also suggested that when this happens, the processor is throttled to reduce the iPhone’s temperature.
However, it is important to note that these tests have been done to benchmark the new iPhones and went through extreme use cases. This may not impact users in day-to-day life, but it remains to be seen how the ‌iPhone 15 Pro‌ models run console-quality games like Resident Evil Village and Death Stranding.
How Apple may fix the issue
Apple is expected to address the thermal issues through software updates. However, improvements may be limited unless the iPhone-maker plans to restrict processor performance. Kuo noted that if Apple is unable to “properly address this issue,” shipments could be impacted over the life cycle of the ‌iPhone 15 Pro‌.
