The Charging Gap: Why Foldables Have Struggled with Wireless Power
A Historical Context: From Wired Dominance to Wireless Ambitions
Foldable smartphones emerged in the late 2010s as a niche innovation, with Samsung’s Galaxy Fold (2019) and Galaxy Z Fold (2020) setting the standard for foldable technology. Early models relied on wired charging due to technical limitations—foldable displays, flexible materials, and the need for robust power management made wireless charging unreliable. By 2021, Samsung introduced 5W wireless charging on the Galaxy Z Fold 3, a modest improvement, but still far behind non-foldable flagships.
This lag was not just technical but also strategic. Foldables were marketed as premium devices for professionals, creatives, and power users who demanded long battery life and rapid refueling. Yet, if wireless charging was slow or unreliable, users would default to wired solutions—undermining the convenience Samsung had promised.
The Competitor’s Edge: Huawei and Xiaomi Lead the Charge
While Samsung lagged, Huawei’s Mate X series (2019) and Xiaomi’s Mi Fold (2020) pushed wireless charging forward with 15W and 20W solutions, respectively. These competitors did not just offer faster charging—they integrated it seamlessly with their ecosystems, ensuring compatibility with home charging pads, car adapters, and even industrial power stations.
By 2023, Xiaomi’s Mi Fold 5G and Huawei’s Mate X4 continued this trend, with some models supporting 25W wireless charging, aligning with the charging speeds of flagship non-foldable smartphones like the Samsung Galaxy S24 Ultra (25W). This created a charging hierarchy:
- Premium foldables (Huawei, Xiaomi): 15W–25W
- Samsung’s early foldables: 5W–10W
- Non-foldables (Samsung, Apple): 25W–30W
The result? Users who needed fast charging for work or travel preferred non-foldables, while foldable enthusiasts settled for slower, less convenient solutions.
The Enterprise Adoption Dilemma: Why Speed Matters for Businesses
For Samsung, the enterprise market was always a critical target. Foldables were designed for professionals who needed multi-device functionality—taking notes on one side, browsing on the other, and powering through long meetings. But if charging was slow, productivity suffered.
A 2023 Deloitte survey found that 68% of business users consider rapid, cable-free charging a decisive factor when evaluating premium smartphones. When asked which features were most important for foldable adoption in corporate settings, wireless charging ranked third, behind only display quality and processor performance.
Yet, Samsung’s foldables were often disconnected from enterprise charging infrastructure. Unlike Huawei’s Mate X series, which included car charging adapters and industrial power stations, Samsung’s foldables relied on proprietary charging pads that were expensive and not universally compatible.
The Problem: If Samsung’s foldables couldn’t charge quickly enough, they risked being perceived as less practical than non-foldable alternatives—even if their fold-and-unfold convenience was superior.
