Samsung warns Apple to keep folding iPhone light

Samsung’s latest memo to Apple stresses that a folding iPhone’s weight will be a decisive factor, according to a Wired report. The Korean conglomerate, which has already released the Galaxy Z Fold 5 and Z Flip 5, says it is “absolutely welcome” to see Apple enter the foldable market but warns that the device’s heft could make or break its success. The note, shared with industry insiders, comes as Apple is expected to unveil a folding model at its next annual developer conference in September.

Samsung’s caution comes at a time when the foldable premium segment is growing fast. Since 2019, Samsung has led the market with two distinct lines: the high‑end Fold, which opens into a tablet‑sized display, and the more compact Flip, which resembles a flip phone. Both devices have carved out a niche among tech enthusiasts and early adopters. Apple’s rumored entry, announced by Apple’s chief design officer in a recent interview, would bring the brand’s design prowess and ecosystem power to the foldable space. Industry analysts predict that a successful iPhone Fold could capture a sizeable share of the $15‑$20 billion global foldable market by 2025, pushing Samsung to maintain a competitive edge.

Weight is a technical hurdle that Samsung says Apple must address. The Galaxy Z Fold 5 weighs 269 grams, while the Flip 5 sits at 181 grams. In comparison, Apple’s current flagship, the iPhone 15 Pro, weighs 188 grams. Samsung’s engineers argue that a heavier foldable phone could feel clunky, reduce battery life, and increase wear on hinges, leading to a poorer user experience. They recommend using lighter materials, such as carbon‑fiber composites or advanced aluminum alloys, and optimizing internal components for a slimmer profile. Samsung also hints that a lighter design could help Apple meet regulatory standards for battery safety and improve portability for everyday carry.

If Apple follows Samsung’s advice and delivers a lightweight folding iPhone, it could shift the competitive landscape. A well‑balanced device would appeal to both power users and mainstream consumers, potentially accelerating mainstream adoption of foldables. Samsung will likely monitor Apple’s design choices closely and could adjust its own product roadmap accordingly. As the launch date approaches, analysts will be watching for any signs that Apple has addressed the weight challenge, as it could determine whether the new iPhone Fold becomes a hit or a cautionary tale in the premium smartphone market.
