The iPhone 15 Professional has an overheating downside that would spell bother for Apple’s customized line of semiconductors.
The newest iPhone Professional is powered by the all-new A17 Professional chip, the primary 3nm chip utilized in a cellular system. Apple’s chips are based mostly on Arm designs that are famend for providing a robust mix of efficiency and vitality effectivity.
Sadly, a myriad of reviews have began surfacing indicating that the iPhone 15 Professional and Professional Max are operating considerably hotter than their predecessors.
Android Authority’s Robert Triggs did a deep dive, completely testing the brand new fashions to see how they evaluate to different flagship gadgets. The outcomes should not excellent news for Apple.
Whereas the iPhone stayed inside a level or two of different flagship gadgets beneath most checks, when the system was used for extra intense operations, the warmth shortly rose far past its rivals.
Nonetheless, as soon as we transfer into extra demanding waters that have interaction extra SoC parts, it’s clear that the A17 Professional chip is a matter. Activate the six-core GPU and temperatures spike shortly. Our iPhone 15 Professional passes the 40°C mark inside 5 minutes of operating the 3DMark Wild Life stress check. Wait till the top of the 20-minute run, and the telephone’s 47°C peak verges on too scorching to carry. The Galaxy S23 Extremely doesn’t do nice right here both, however the iPhone 15 Professional is 5.7% hotter, and any handheld system approaching 50°C with any workload is worrisome.
Our 4K/60 video recording check showcases probably the most important discrepancy. After simply 5 minutes, the iPhone 15 Professional is about 7°C hotter than the S23 Extremely and 4°C hotter than the Pixel 7 Professional, a telephone already extensively considered too heat. Worse, the iPhone 15 Professional far exceeds a suitable stage of consolation within the hand after extending the check to 10 minutes.
Whereas a single mannequin overheating is regarding sufficient, it’s particularly so when contemplating the iPhone Professional makes use of the most recent and best Apple-designed, TSMC-manufactured silicon.
The outcomes elevate questions on whether or not Arm-based semiconductor design nonetheless has room to extend efficiency with no important improve in warmth, or whether or not it has hit a thermal restrict.
