The upcoming iPhone 16 lineup could offer significantly longer battery life: Apple is increasing the energy density of batteries in its upcoming devices, allowing them to last longer between charges, analyst says of the Ming-Chi Kuo supply chain. Kuo points out that higher energy density leads to higher heat production: To address this challenge, Apple is encapsulating the new batteries in stainless steel. This choice will not only help dissipate heat better, but will also make the batteries easier to replace. This feature responds to new European Union regulations, which now require greater ease of replacing batteries in electronic devices.
The decision to use stainless steel for the battery casing represents a significant change from previous models. Traditionally, iPhone batteries have been encased in less durable materials that offer limited protection against heat. The move to stainless steel not only improves thermal management, but also offers greater overall durability for the device. The iPhone 16, therefore, in addition to the introduction of Apple’s artificial intelligence, could represent an interesting turning point in smartphone battery technology. The next generation of smartphones will be unveiled in September.
