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.
ASUS Zenfone 12 Ultra
The gimbal-stabilized main camera is the genuine highlight; the rest of the system is solid-for-the-price but clearly trails rival flagships.
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.
ASUS Zenfone 12 Ultra
Snapdragon 8 Elite plus ROG-derived cooling makes this a fast, stable performer with no thermal drama.
Motorola Razr Fold
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.
ASUS Zenfone 12 Ultra
Strong real-world endurance from the 5,500mAh cell with fast 65W charging — though lab testing shows a regression versus the 11 Ultra.
Motorola Razr Fold
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.
ASUS Zenfone 12 Ultra

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.
