GoKawiilCNET Lab Tests Rank Foldable Phone Battery Life Across Samsung, Apple, Google, Motorola
CNET tested five book-style foldable phones in 2026 — the Samsung Galaxy Z Fold 8 and Z Fold 8 Ultra, Motorola Razr Fold, Google Pixel 11 Pro Fold and Apple's new iPhone Duo — to compare battery performance using its smartphone lab data. The outlet separated book-style and flip-style foldables for comparison due to differences in design and screen size, noting the Galaxy Z Fold 8 can last a full day despite its slim build.
