Apple began selling the new iPhone 15 on September 22. After a week of use, many people have begun sharing their experiences. According to some iPhone 15 Pro and 15 Pro Max users, even after only a few minutes of use, the device became too hot to hold. Meanwhile, some said that the two high-end iPhones did not pass the “bend test” and were prone to breaking even when bent with bare hands. Others noticed that the devices changed color if they were not used with a case.
Content creator Mohit Verma sparked the discussion about the temperature of the iPhone 15 in a post on X (Twitter) on September 25. He wrote: “The iPhone 15 Pro titanium suddenly gets extremely hot, to the point where it is unusable to hold. Also, its temperature increases after just 2 minutes of FaceTime calls or when scrolling Reels (feature on Instagram) for 8-10 minutes. This is a new issue for me as I have never faced this with any phone before.”
Verma attached a video – now viewed over 1 million times – to back up his claim. In the video , he uses a thermometer to measure the temperature of the iPhone 15 Pro. The device hits 42 degrees Celsius.
Under the post, another X user commented that he was experiencing the same thing when doing simple tasks like listening to a podcast. In addition, the battery drained faster than usual. However, some people dismissed this. “It’s definitely faulty. Go to the Apple Store and get a new phone,” one person emphasized.
Korean YouTuber BullsLab filmed the iPhone's temperature using a thermal imaging camera. While using the iPhone for gaming, heavy tasks, and benchmarking, the device's temperature reached 46 degrees Celsius.
In another viral video, the glass back of the iPhone 15 Pro Max cracked after being bent with bare hands. The video, by Zack Nelson – owner of the JerryRigEverything channel – has attracted more than 7.7 million views on YouTube.
“You guys have been watching me do smartphone durability tests for about 11 years now, and most phones don’t break,” Nelson explains in the clip. “In particular, iPhones don’t break.” But the iPhone 15 Pro Max is a different story, and it shocked Nelson.
Many people hypothesize that the lighter titanium frame makes the iPhone 15 Pro more “fragile” than previous iPhone models. In addition, the titanium material is also prone to fingerprints and temporary discoloration if not used with a protective case.
According to TechRadar, Apple admits that “ with iPhone 15 Pro and 15 Pro Max, oils from your skin may temporarily change the color of the exterior.” However, simply wipe the device with a soft, slightly damp, lint-free cloth to restore its original appearance.
Regarding the issue of iPhone 15 Pro overheating, expert Ming Chi Kuo conducted his own survey and said that it has nothing to do with the A17 Pro chip manufactured on TSMC's 3nm process. According to Mr. Kuo, the main reason is most likely that Apple has compromised in the design of the thermal system to achieve a lighter weight, such as reducing the heat dissipation area. The use of a titanium frame also negatively affects the heat dissipation efficiency.
Experts predict that Apple will address this through a software update, but the impact may be limited unless Apple reduces processor performance. If Apple does not address it properly, this will negatively impact sales of the iPhone 15 Pro lineup.
