Motorola's first book-style foldable trades the iconic flip for a Samsung-like book form, with a Material Expressive look, a flat-folding hinge and a notably heavy body.

Samsung Galaxy S26 Ultra
Slimmer (7.9mm vs 8.2mm), lighter (214g vs 218g), back to aluminum frame after two years of titanium, softer rounded corners that lose the last of the Note family's boxy heritage, and a new unified camera plateau that aligns with the Z Fold 7. The S Pen now has a rounded cap that only inserts one way. Reviewers are split on whether the new design is a confident refresh or a step closer to looking like the S26+/Pixel/iPhone crowd.
Motorola Razr Fold
Historically the foldable Achilles heel — but Motorola invested in hardware and software here, and DxOMark ranks it the best camera in any foldable.
Samsung Galaxy S26 Ultra
Same sensors as the S25 Ultra (200MP main 1/1.3in, 50MP ultrawide, 10MP 3x telephoto, 50MP 5x periscope, 12MP selfie) but the main and 5x get wider apertures (f/1.4 from f/1.7; f/2.9 from f/3.4). Reviewers agree the low-light gain is real and visible without leaning on AI. New software tricks: APV codec for near-lossless 1080p/4K video, Horizon Lock super-stabilization, and an expanded Photo Assist with generative editing. The unloved 10MP 3x sensor and AI-aggressive 30x+ zoom are the recurring weak points.

Snapdragon 8 Gen 5 with 16GB RAM — fast for everyday use and surprisingly good in long sessions, but the choice of the non-Elite chip in a $1,899 phone is the headline criticism.
Samsung Galaxy S26 Ultra
Snapdragon 8 Elite Gen 5 for Galaxy, paired with 12 or 16GB RAM and up to 1TB storage, comfortably tops every published Android benchmark and trades blows with the iPhone 17 Pro in single-core. A redesigned, larger vapor chamber keeps sustained performance up, though Wild Life stress runs still shed 30-40% of peak GPU output under load.

The standout: the largest battery in the book-foldable space delivering class-leading endurance, plus 80W wired charging — three times faster than the Galaxy Z Fold 7.
Samsung Galaxy S26 Ultra
The S26 Ultra inherits the same 5,000 mAh capacity Samsung's used since the S20 Ultra — six years unchanged — but 60W wired charging is genuinely faster and Qi 2.2 25W wireless is overdue. Reviewers split: most say battery life is 'fine' but no longer flagship in a market where OnePlus 15 ships with 7,300 mAh and Oppo Find X9 Pro packs 7,500 mAh. Charging speeds are now a competitive feature, not a weakness.

The surprise strength — Motorola's foldable software is widely called the best balance of Pixel simplicity and Samsung multitasking, undercut only by Motorola's update-timeliness history.
Samsung Galaxy S26 Ultra
One UI 8.5 ships on Android 16 with seven years of OS + security updates promised. Beyond the new transparent glass UI choices, the story is Galaxy AI — Now Brief, Now Nudge, Photo Assist, Creative Studio, summarized notifications, plus Gemini task automation (beta) for limited ride-share and food-delivery flows. Reviewers split sharply on whether the AI features are genuinely useful or 'slop', but a local-only AI processing toggle gets near-universal praise.
Motorola Razr Fold
At $1,899 it undercuts the Z Fold 7 and is the only premium book foldable many US buyers can actually purchase — value hinges on whether the non-Elite chip and update questions matter to you.
Samsung Galaxy S26 Ultra
At $1,300 starting (256GB), $1,499 (512GB), $1,799 (1TB), the S26 Ultra still costs more than the OnePlus 15 ($899 with double the storage), the Pixel 10 Pro XL ($1,199), and the iPhone 17 Pro Max ($1,199). Reviewers position the value case around the privacy display, the camera versatility, the seven-year update window, and the One UI ecosystem rather than raw spec-for-spec parity.
