The Google Pixel 10 Pro Fold, marketed as Google’s “most durable foldable ever,” recently faced a catastrophic battery explosion during a stress test by popular YouTuber JerryRigEverything, marking an unprecedented event in a decade of smartphone testing. This incident, coupled with lingering questions about its IP68 dust resistance and a history of structural weaknesses mirroring previous Pixel Fold models, presents significant concerns for investors scrutinizing Google’s hardware division and the long-term viability of foldable smartphone technology.
On October 14, a routine stress test on the new Google Pixel 10 Pro Fold took an alarming turn when the device’s battery unexpectedly exploded. This unprecedented incident, captured on video by renowned durability tester Zack Nelson of JerryRigEverything, has sent shockwaves through the tech community and raised critical questions for investors regarding Google’s hardware strategy and the future of the foldable smartphone market. The incident marks the first battery explosion in Nelson’s decade-long career of testing smartphones, casting a shadow over Google’s claims of producing its “most durable foldable yet,” as reported by Fortune.
The Exploding Device: A Critical Engineering Failure
The catastrophic failure occurred during Nelson’s bend test, an extreme scenario designed to push devices to their limits. After the phone’s structure had already fractured at an antenna line, Nelson attempted to straighten it. This action caused the battery’s internal layers to pinch together, leading to a short circuit and an immediate thermal runaway. Thermal runaway is a self-perpetuating process within lithium-ion batteries where heat generation exceeds the battery’s ability to dissipate it, triggering exothermic reactions that can elevate temperatures beyond 1,000 degrees Celsius and result in fire or explosion.
What makes this incident particularly concerning for investors is not just the explosion itself, but the nature of the failure. The device broke at the exact same structural weak point—the antenna lines near the hinge—that plagued its predecessors, the original Pixel Fold and the Pixel 9 Pro Fold. This recurring vulnerability suggests a fundamental design flaw that Google has failed to address across generations, despite marketing the Pixel 10 Pro Fold as a pinnacle of durability.
IP68 Rating Under Scrutiny: Dust Resistance Claims Questioned
Beyond the explosion, Nelson’s testing also challenged Google’s claims regarding the phone’s IP68 dust and water resistance, a feature Google prominently highlighted as a unique selling point for its new foldable. Google had stated that its “gearless hinge” design eliminated tiny spaces, making the Pixel 10 Pro Fold the first foldable to achieve full IP68 certification, according to a Google blog post.
However, when Nelson poured sand into the hinge during his dust resistance evaluation, the phone emitted “disturbing crunching sounds.” This strongly indicated that particles had infiltrated the mechanism, directly contradicting Google’s claims and the supposed efficacy of its redesigned hinge. While lab conditions for IP ratings differ from real-world “torture tests,” the ease with which dust penetrated the device raises questions about its practical resilience in daily use, where pocket lint and environmental dust are constant companions.
A History of Fragility: Pixel Fold Line’s Recurring Durability Issues
The Pixel 10 Pro Fold’s issues are not isolated incidents but rather a continuation of durability challenges that have plagued Google’s foldable line since its inception. The original Google Pixel Fold launched to reports of inner screens cracking after less than a week of use, with users on Reddit posting photos of cracks spreading from the middle of the display. Ron Amadeo of Ars Technica even experienced screen damage from a small speck of debris, attributing it to the screen protector not fully covering the OLED display and the phone folding completely flat without bumpers.
This history of fragility is a significant concern for investors. While other foldable manufacturers like Samsung also faced early durability issues with their first-generation devices, they have made strides in subsequent models. The fact that Google’s latest iteration fails at the same antenna line weak point and struggles with dust ingress despite its IP68 claims suggests a slower learning curve in critical mechanical design compared to its competitors.
Investment Implications: Brand Trust, Market Share, and Future Innovation
For investors, the Pixel 10 Pro Fold’s durability debacle presents several critical implications:
- Brand Reputation and Trust: Google’s explicit marketing of the device as “extremely durable” and having industry-leading IP68 resistance is now severely undermined. A battery explosion, even in an extreme test, is a serious blow to consumer confidence and could lead to significant brand damage, impacting sales across Google’s hardware portfolio.
- Competitive Disadvantage: In the fiercely competitive foldable market, where players like Samsung (with models like the Galaxy Z Fold 7) have seemingly avoided similar catastrophic failures in identical tests, Google’s position looks precarious. This could hinder its ability to capture significant market share in a segment that, while niche (around 1% of worldwide smartphone ownership in 2023), holds significant long-term growth potential.
- Increased Costs and R&D Burden: Recurring design flaws and potential safety concerns could lead to higher warranty claims, increased customer service costs, and the need for costly redesigns. Investors might question the efficiency of Google’s hardware R&D, especially for a device that retails at a premium price point of $1,799 to $2,149.
- The Future of Foldable Design: The incident forces Google, and potentially the broader industry, to re-evaluate fundamental mechanical design choices. Should Google prioritize robust chassis and battery protection even if it increases weight or thickness? This is a trade-off that impacts user experience and competitive positioning.
While Google excels in software, AI, and photography, the mechanical execution of its foldable hardware appears to be lagging. The company must address these engineering vulnerabilities decisively to maintain investor confidence and secure a meaningful foothold in the evolving smartphone market.

Looking Ahead: A Wake-Up Call for Google
The Pixel 10 Pro Fold debacle serves as a serious wake-up call for Google. As the company continues its push into hardware, particularly in innovative but challenging form factors like foldables, fundamental engineering and safety cannot be overlooked. Relocating vulnerable components like antenna lines and reinforcing battery protection zones will be crucial steps to prevent future incidents and build the necessary trust with consumers and investors alike. The long-term success of Google’s foldable ambitions, and indeed the broader acceptance of foldable technology, hinges on overcoming these persistent durability hurdles.
