IPhone 16 Pro Max or the first stainless steel battery case for enhanced thermal protection

According to well-known analyst Guo Mingxuan, Apple plans to launch iPhone 16 Pro Max improves the energy density of its battery. This means that under the same volume, the mobile phone Its endurance will be stronger; In the case of the same endurance, its volume will also be smaller.

In order to deal with the heat problem caused by the increase of battery energy density, Apple used a stainless steel battery case for the first time to dissipate heat. Although the heat dissipation effect of stainless steel is not as good as that of aluminum, its durability and resistance corrosion More sexual. In addition to heat dissipation, the stainless steel battery case can also provide better protection performance, which protects the battery and iPhone system. The use of stainless steel battery case can also reduce the difficulty of battery disassembly, which also helps Apple meet the requirements of EU regulations for mobile phone battery disassembly in the future.

Xinwei Communication is one of the main suppliers of stainless steel battery cases. According to the order volume, this order will contribute less than 5% to the revenue of SINO Communications in 2024. However, due to Apple's high requirements for stamping production procedures, the gross margin of stainless steel battery shells is better than that of ordinary metal stampings, and it is expected to achieve good profits in the second quarter.
