The iPhone 15 has garnered a lot of attention since its launch, but not all that glitters is gold. Below, we'll take a closer look at the reports of iPhone 15 overheating issues. From extreme temperatures to unexplained heat buildup, we'll take a look at this issue that's affecting many users.
There are numerous reports from iPhone 15 owners of a serious overheating issue that seems to affect all models. Some users report temperatures reaching over 40°C, which is well beyond acceptable limits. This problem seems to occur regardless of whether the phone is charging via cable or not.
iPhone 15 overheating reports: A look at the facts
Some people have reported experiences where, for example, the iPhone 15 Pro Max became so hot that it was almost impossible to touch, especially during fast charging. Interestingly, the left sidebar and part of the left back panel were found to become particularly hot when the phone was held in the hand. This problem became particularly acute in a battery charge range of 25-60%. Some users also noted that the overheating occurs even when the phone is used for less demanding tasks such as browsing social networks. I have also experienced this phenomenon with my iPhone 15 Pro Max. This raises serious concerns about the overall usability of the devices.
The role of initial setup and testing with infrared cameras
iPhones are known to get a little warmer in the first 24 hours after use, especially when setting up from an older device or an iCloud backup. This is due to background processes like reinstalling apps and reindexing. But the reports of overheating go beyond this initial phase. Korean YouTubers like BullsLab have conducted tests using infrared cameras, also known as thermal imaging cameras, which showed shocking temperatures of up to 46.7°C during demanding use, including benchmarks and gaming, highlighting that the problem is particularly severe under intensive use.

Even with easier tasks: The inexplicable heat
Some users, like Aamir Siddiqui of Android Authority, reported overheating issues even when doing less demanding tasks, like switching between chat apps or watching videos on Instagram. The phone, in this case, heated up in the area below the camera island on the right side, even without playing games or plugging it into the charger.
