Does the iPhone 15 still have a heating problem?

After Apple launched the iPhone 15 series last fall, some of the early users who had access to these phones encountered a heating problem and raised this issue through social networks.

Apple quickly released a software update to solve the heating problem. However, a few months later, some iPhone 15 owners were still complaining about their devices heating up.

One Reddit user said, “Apple’s quality control has significantly decreased.” Another user reported, “My iPhone 15 Pro Max gets hot even when I’m not using it.”

Another person confirmed this problem and wrote, “My iPhone 15 Pro Max gets hot and the battery drains quickly.”

What was Apple’s response?

On October 7, 2023, the creator of the iPhone and MacBook released an update and claimed that the bug caused by the initial setup, which was the main reason for the excessive heating of the phones, has been resolved.

The Cupertino-based company announced, “We have identified several reasons that may cause the iPhone to overheat. The phone’s temperature may increase in the first few days after setup or recovery due to the execution of many activities in the background.”

Did the operating system update really solve the problem?
Despite several iOS 17 updates, some iPhone 15 users are still complaining about its excessive heat. Interestingly, Apple indirectly confirmed this issue and called the performance of the iPhone 15 Pro and Pro Max at higher temperatures than previous iPhones their “expected behavior”. Therefore, the iPhone 15 heating problem still exists, but not as severely as before.

It seems that the technology giant from Cupertino intends to completely solve the thermal problem of its phones with the use of graphene in the iPhone 16; a problem that it ultimately could not solve with software. We have to see how much the use of graphene will affect the price of the iPhone 16 series.


What is graphene?

Graphene is an atomic-scale hexagonal lattice made of carbon atoms. It is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice. Each atom in a graphene sheet is connected to its three nearest neighbors by σ-bonds and a delocalised π-bond, which contributes to a valence band that extends over the whole sheet.

Graphene is a one-atom-thick layer of carbon atoms arranged in a hexagonal lattice. It is the building-block of Graphite (which is used, among others things, in pencil tips), but graphene is a remarkable substance on its own – with a multitude of astonishing properties which repeatedly earn it the title “wonder material”.

Graphene conducts heat and electricity very efficiently along its plane. The material strongly absorbs light of all visible wavelengths, which accounts for the black color of graphite, yet a single graphene sheet is nearly transparent because of its extreme thinness. Microscopically, graphene is the strongest material ever measured.

Graphene is a material that is extracted from graphite and is made up of pure carbon, one of the most important elements in nature and which we find in daily objects like the lead of a pencil. Graphene stands out for being tough, flexible, light, and with a high resistance.
Graphene is a single layer of carbon atoms arranged in a hexagonal lattice structure, forming a two-dimensional (2D) material with exceptional mechanical, electrical, and thermal properties. It is widely studied for its potential use in various fields such as electronics, energy storage, and biomedicine.
