Nintendo Switch 2 Leaks: Replaceable Battery and Secret EU Designs

Nintendo confirms EU-bound ‘Switch 2’ prototype with modular battery—raising questions about global release strategy

Nintendo has officially acknowledged the existence of a prototype for its next-generation console, codenamed “Switch 2,” in the European Union, where regulatory filings reveal a design featuring an interchangeable battery module—a feature absent in the current model. The confirmation, first reported by heise online and later corroborated by Nintendo’s own submissions to the European Union Intellectual Property Office (EUIPO), marks the first concrete detail about the console’s hardware evolution since cryptic references to a “Switch 2” code surfaced earlier this year.

The EUIPO filings, registered under four distinct design patents, depict a console shell nearly identical to the original Switch in form factor but with a detachable battery compartment positioned on the underside. Industry analysts speculate this could address long-standing consumer complaints about the current model’s battery life, particularly in handheld mode, where players often report durations as short as two to four hours for demanding titles. Nintendo has not disclosed whether this modular design will extend to all regions or if it represents a localized adaptation to EU regulations on right to repair and sustainability directives, which have grown stricter in recent years.

In a statement to Nintendo Connect, the company declined to comment on the prototype’s status beyond confirming its existence. “We are always exploring ways to improve the experience for our players,” a spokesperson said, adding that “any final product would undergo rigorous testing before release.” The vagueness mirrors Nintendo’s historically cautious approach to teasing hardware, where even minor details—such as the inclusion of a pro controller in the original Switch reveal—were met with years of speculation.

The revelations follow the recent decoding of a cryptic “Switch 2” code embedded in the firmware of the current console, which jpgames.de reported last month. While the code itself offered no technical details, its presence suggested Nintendo was internally referencing a successor project. The EU filings now provide the first physical evidence of that work, though the absence of a formal announcement leaves critical questions unanswered: Will the modular battery be a standard feature, or a regional exception? Are other hardware upgrades—such as a more powerful chipset or improved thermal management—already in development?

Industry reactions hint at broader implications

The modular battery design has sparked comparisons to Sony’s DualSense controller, which also introduced a removable battery pack—a move widely seen as a response to consumer demand for longer play sessions. In an interview with PlayFront, a Sony spokesperson declined to comment on whether the company viewed Nintendo’s prototype as a competitive threat, stating only that “we remain focused on delivering innovative experiences for our users.” The parallel developments underscore how console manufacturers are increasingly prioritizing battery longevity and repairability as key differentiators in an era where sustainability and cost-of-ownership concerns are reshaping consumer expectations.

Meanwhile, the timing of the EU filings—submitted just weeks after Nintendo’s fiscal year ended—raises questions about whether the company is preparing for a regional launch of the Switch 2 before a global rollout. The European market has historically been an early adopter for Nintendo hardware, given its strong sales performance and regulatory environment that often precedes broader approvals. However, Nintendo has not provided a timeline, and industry leaks suggest internal debates persist over whether to prioritize software maturity (with next-gen titles like Zelda and Metroid sequels in development) or hardware readiness.

A puzzle piece without the full picture

Despite the prototype’s confirmation, fundamental questions remain unanswered. Nintendo has not disclosed whether the modular battery will be user-serviceable or require professional assistance, a critical distinction given the EU’s right to repair legislation. Nor has the company clarified whether the Switch 2 will retain the original’s hybrid docking system or adopt a new approach—such as a standalone handheld design, which rumors have persistently circulated since 2021.

What is clear is that Nintendo is actively progressing the project. The four EUIPO filings, submitted between March and May 2024, cover variations in color schemes, port placements, and shell materials, suggesting iterative design phases. Yet the absence of a public roadmap—combined with Nintendo’s tendency to delay hardware announcements until the final quarter—leaves the industry in a state of informed speculation.

The next concrete step may come from Nintendo’s own channels. Earlier this year, the company registered a domain (switch2.nintendo.com), which currently redirects to a placeholder page. Whether this signals an impending reveal or remains a placeholder for internal use is unclear. For now, the modular battery prototype stands as the most tangible evidence yet that the Switch 2 is not merely a rumor—but a project in its final stages of hardware definition, even if its release remains shrouded in silence.
