Some of the recent owners of Apple’s iPhone 15 phones have noticed that their devices heat up significantly when charging or even when in use. Several sites focused on technology news reported on the matter.
Editor of 9to5Mac Ian Zelbo is told in the X service (formerly Twitter) During fast charging, the iPhone 15 Pro Max heats up almost so hot that you can’t touch it.
According to Zelbo, the device was at its hottest when the charge was between 25 and 60 percent. After reaching the 70 percent level, the device cooled down clearly, which is related to the automatic slowing down of the charging power when the battery is nearing full.
Zelbo also points out that the temperature rose especially near the phone’s motherboard on the left side of the phone.
Also the Wall Street Journal Joanna Stern and 9to5Google Max Weinbach reported that the iPhone 15 Pro Max heats up significantly during charging.
The A17 Pro chip used in the Pro models was reported in the first Chinese reviews of the device to heat up especially during gaming, writes BGR website.
In thermal camera measurements, iPhone 15 models have heated up to almost 47 degrees during demanding use, he writes 9to5Mac website. According to the site, some users have noticed heating even during light use, such as browsing on social media.
Of course, it is normal for a new iPhone to run hot during the first day or two after use. This happens especially when restoring the system from an old iPhone or from a backup made to the iCloud cloud service. Reinstalling applications in the background and indexing photos, for example, load the device.
However, the reported heating problems have continued longer than usual. Initially, there was speculation that the background could be the more disappointing than expected performance of Apple’s new A17 chip in relation to the fact that it was designed with the new, expected three-nanometer manufacturing process. In other words, Apple would have slightly overclocked the phones’ CPUs relative to what the phones were originally designed for, to make the phones look better in performance comparisons.
A financial analyst who is considered a trusted Apple expert Ming-Chi Kuon according to the heating problem is not caused by the A17 chips. Kuo himself believes that the heating is due to the design of the device: on the one hand, from its smaller heat loss area than its predecessor, on the other hand, from the titanium used in the body of the Pro models, whose thermal conductivity is worse than steel. Kuo writes about his findings On the Medium platform.
