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.
GoKawiil's interpretation of the reporting above, not reported fact.
Battery life has historically been a weak point for foldables due to their large displays, hinge mechanisms and limited space for heat dissipation, so improvements suggest the category is maturing technically. CNET's testing indicates that advances such as silicon-carbon batteries and more efficient processors are narrowing the gap with traditional slab phones, which could make foldables more appealing to mainstream buyers. Apple's entry with the iPhone Duo may also signal growing legitimacy for the foldable category as a whole.
- CNET tested five book-style foldables in 2026, including new entrants from Apple and Google.
- Newer battery technology like silicon-carbon cells is helping foldables close the battery-life gap with slab phones.
- Apple's $1,999 iPhone Duo marks its first foldable entry, arriving later than competitors from Samsung and Motorola.
