As more and more users get Apple iPhone 15 series models, related usage problems are gradually exposed. Users have complained a lot about the overheating of the new iPhone 15 Pro and Pro Max models. Some users claimed on Apple’s official iPhone community forum that the titanium case was too hot to hold.

A user wrote on Apple's official forum: "I bought the new iPhone 15 Pro. It is too hot to handle. Can I leave it charging for a long time?" This question received "metoo" clicks from hundreds of users.

There are also user complaints about the overheating of the Apple iPhone 15 Pro series on social platforms X and Reddit. Someone on the Apple forum posted that the thermometer next to the phone showed a temperature of 44 degrees Celsius.

Apple has not yet issued an official response to the problem of overheating of its mobile phones, nor has it provided public feedback on user issues on its official forum.

However, the company's customer support page notes that the device may become warm during first-time setup, wireless charging, or when the user uses graphics-intensive or processor-intensive applications such as games.

In fact, it’s not just the iPhone 15 Pro that has overheating issues, the iPhone 14 Pro and Pro Max also have similar overheating issues. The iPhone 15 Pro series casing is made of titanium metal, which is thinner and lighter than the stainless steel metal of the iPhone 14 Pro. Although the two have similar thermal conductivity properties, because the titanium metal is lighter and absorbs less heat, iPhone 15 Pro users may experience poor heat dissipation more significantly.

According to Apple’s official website, iPhone 15 Pro and iPhone 15 Pro Max are made of sturdy and lightweight aviation-grade titanium, bringing Apple’s lightest Pro models ever. This has also become a big selling point for the company in promoting this year's new iPhone Pro models.

Ming-Chi Kuo believes that Apple may solve this problem through software updates, but unless it reduces the performance of the processor, the improvement in heat dissipation may be limited. He also said that if the heat dissipation problem is not solved, it may affect iPhone Pro sales.

Tests by the iPhone repair website iFixit show that the iPhone 15 Pro with a titanium alloy shell and the iPhone 14 Pro with a stainless steel shell are not as good at thermal conductivity as the aluminum alloy materials used in the basic models of the iPhone 14 and iPhone 15, but Apple can reduce the heat generated by the phone by reducing the peak performance of the phone's processor.

CCSInsight principal analyst Ben Wood believes that even if Apple implements software updates to limit the peak performance of the processor, the vast majority of mobile phone users will not notice these performance changes. He also said that judging from past practice, overheating issues will not lead to recalls of Apple phones.

Apple's high-end iPhone Pro models have been the company's main product series in recent years to maintain high gross profit margins on mobile phones. Market forecasts also show that demand for Pro models has grown significantly since the release of iPhone 14, with shipments even exceeding that of basic models, especially in emerging markets such as China and India.

A reporter from China Business News checked Apple's official website in China and found that the delivery cycle of the iPhone 15 Pro has been shortened from last week. The current order is placed and the estimated delivery date is 2-3 weeks; however, the estimated delivery date of the iPhone 15 Pro Max is longer, 5-6 weeks. In contrast, there is no need to wait for the basic iPhone 15 model.

Brokerage Wedbush said that most of Apple's early pre-orders for the iPhone 15 series come from iPhone 15 Pro and iPhone 15 Pro Max, which is a good thing for Apple because the Pro series has a higher average selling price (ASP), which helps improve the company's profit margins. The company predicts that the ASP of the Apple iPhone 15 series will be around US$925, which is about US$100 higher than the same period last year. The price of the ProMax model has increased by 9%, which is also the first price increase in five years.
