1. Fold series in a nutshell
The Galaxy Z Fold line is all about turning a phone into a tablet—and back again. From the Fold 4 to Fold 6, Samsung has refined this concept with lighter builds, better durability, and smarter features.
But if you’re wondering what’s really changed under the hood—here’s a breakdown that skips the fluff and gets straight to what matters.
2. Design and hinge evolution
| Model | Weight | Folded Thickness | Hinge |
|---|---|---|---|
| Z Fold 4 | 263g | 15.8mm | Standard U-shape hinge |
| Z Fold 5 | 253g | 13.4mm | New Flex Hinge (zero gap) |
| Z Fold 6 | 239g | 12.1mm (slimmer than ever) | Titanium Flex Hinge |
The Fold 6 is the lightest and slimmest yet, with a flatter design and better feel in hand.
3. Display upgrades
- Z Fold 4: 7.6" inner QXGA+, 6.2" outer – solid but narrow cover screen
- Z Fold 5: Same size, brighter peak brightness
- Z Fold 6: Wider 6.3" outer, anti-reflective inner display, 2600 nits brightness
The Fold 6 makes multitasking on the outer screen feel less cramped and more usable day-to-day.
4. Performance and hardware
- Fold 4: Snapdragon 8+ Gen 1
- Fold 5: Snapdragon 8 Gen 2 for Galaxy (faster GPU)
- Fold 6: Snapdragon 8 Gen 3 (improved thermals, AI acceleration)
For heavy multitaskers, the Fold 6 not only opens apps faster, but handles DeX and split-screen more efficiently.
5. Camera and productivity
| Model | Main Camera | Front Camera | S Pen Support |
|---|---|---|---|
| Fold 4 | 50MP + 10MP + 12MP | Under-display (4MP) | Yes (optional pen) |
| Fold 5 | Same hardware, better processing | Improved 4MP UDC | Yes, case accessory needed |
| Fold 6 | New sensor tuning, better HDR and zoom | Refined under-display tech | Yes, still no slot |
For photography, S Pen sketching, and video meetings, Fold 6 delivers smoother and smarter results—especially under tough lighting.
6. Battery life and durability
- All models have 4400mAh battery + 25W wired / 15W wireless charging
- Fold 6 improves endurance thanks to software tuning and Snapdragon efficiency
- Durability: Fold 6 has Gorilla Glass Armor + stronger hinge tolerance
7. Final thoughts
Fold 4: Still capable, best for used deals
Fold 5: Balanced refinement, ideal for most upgraders
Fold 6: Slimmest, smartest, and most refined—especially if you're in on the AI and multitasking game
If you're upgrading from Fold 4 or earlier, Fold 6 is a noticeable leap. From Fold 5? Upgrade if you want a lighter device or use the outer screen a lot.
