Samsung's next-generation foldables are here | The Vergecast Livestream

What It Covers

Samsung's Unpacked event introduces three foldable devices — the Z Fold 8 (wide), Z Fold 8 Ultra (tall), and Z Flip 8 — alongside Galaxy Watch 9 and Watch Ultra 2. Hosts David Pierce and Nilay Patel evaluate form factors, silicon-carbon battery technology, Gemini AI integration, and whether these $1,200–$2,100 devices justify their price.

Key Questions Answered

• •Wide foldable form factor: The Z Fold 8's 16:10 exterior and 4:3 interior screen ratio resolves a longstanding foldable design problem — the shorter, wider profile allows thumb reach across most of the display. Every hands-on reviewer reported the same reaction: it feels natural immediately despite looking squat in photos. This consensus suggests Samsung found the correct foldable geometry.
• •Silicon-carbon battery trade-offs: Samsung's Z Fold 8 series debuts silicon-carbon battery chemistry in mainstream US phones, offering higher energy density in smaller size. Samsung deliberately applied the technology conservatively rather than maximizing capacity, acknowledging silicon expands more and degrades faster than lithium-ion. Buyers of $2,000+ devices should factor in accelerated capacity loss over a two-year ownership cycle.
• •Gemini vs. Siri AI gap: Google Gemini's proactive, minute-to-minute assistance — surfacing calendar additions, task automation across Ticketmaster, Uber, DoorDash, Expedia, and Resi — currently outpaces Apple's Siri AI meaningfully. Samsung's early access to Gemini features positions Android foldables as the primary testing ground for agentic AI before Apple's competing foldable launches in September 2026.
• •Price ceiling kills mainstream adoption: No Samsung foldable reviewed here crosses into mass-market territory. The Z Flip 8 at $1,200 represents the lowest entry point; the Z Fold 8 Ultra reaches $2,100. Historical precedent shows foldables need pricing closer to $800–$1,200 to drive switching behavior. Until that threshold is reached, these remain high-end science projects rather than category-defining products.
• •Ecosystem lock-in limits competition: Galaxy Watch 9 and Watch Ultra 2 (60-hour rated battery, 5,000 nits brightness, diving certification) do not realistically compete against Apple Watch for iPhone users. Smartwatch purchasing decisions are dictated almost entirely by phone ecosystem, not feature differentiation. Buyers should evaluate the full Samsung Galaxy ecosystem — phone, watch, glasses — as a single purchasing decision rather than individual devices.
