Samsung’s next-generation foldable flagship, the Galaxy Z Fold7, is expected to redefine slim design standards in the foldable smartphone category. While an official announcement is still pending, a series of leaks and industry insider tips hint at significant design improvements, performance upgrades, and subtle refinements that may give Samsung an edge in the premium foldable market.

Key Highlights

Galaxy Z Fold7 tipped to measure just 3.9mm when unfolded, and 8.9mm when folded

Could beat OPPO Find N5 to become the thinnest foldable phone

Expected to feature faster 45W wired charging

May continue with 4400mAh battery capacity

New S Pen with a thicker tip for better usability

Launch expected around July 2025

Slimmer Than Ever Before: New Dimensions Revealed

According to reputable tipster ICE CAT (@UniverseIce), the Galaxy Z Fold7 will surpass previous foldables in slimness, coming in at just 3.9mm when unfolded and 8.9mm when folded. This would make it even thinner than OPPO’s Find N5, which holds the current record at 4.21mm unfolded and 8.93mm folded.

Early rumors had previously pointed to a slightly thicker profile (4.5mm/9mm), but these new measurements suggest Samsung is going all-in on making this its most streamlined foldable device yet.

Battery and Charging Upgrades

While Samsung is expected to retain the 4400mAh battery seen in its predecessor, the Galaxy Z Fold6, the Z Fold7 may introduce 45W fast wired charging support — a considerable bump from the previous 25W standard. This should lead to significantly reduced charging times, offering a better day-to-day experience for power users.

Enhanced S Pen Experience

Another standout upgrade may come in the form of a redesigned S Pen. Reports suggest Samsung will equip the Galaxy Z Fold7 with a thicker-tipped stylus, aimed at improving precision and comfort when writing or sketching on the large foldable display. This change addresses previous complaints of the S Pen feeling too “scratchy” or unnatural on flexible screens.

Galaxy Z Flip7 and the S26 Series Could Follow Suit

Samsung is also reportedly working on the Galaxy Z Flip7, which may pack a 4300mAh battery — aligning with its predecessor but possibly benefiting from new power management features.

In a related development, Samsung’s future flagship — the Galaxy S26 series — is also rumored to carry forward the thin design ethos, pointing to a broader brand strategy focused on sleek, lightweight builds without compromising functionality.

Expected Launch Timeline

Although official details are scarce, the Samsung Galaxy Z Fold7 is widely expected to be unveiled in July 2025, alongside the Flip7 and possibly other accessories or ecosystem devices. More leaks and specifications are likely to surface in the coming weeks, giving enthusiasts a better idea of what’s in store.

Conclusion

If these leaks hold true, the Galaxy Z Fold7 could set a new benchmark for foldable smartphone design. With its ultra-thin form factor, improved S Pen functionality, and faster charging, Samsung appears poised to strengthen its leadership in the foldable space — giving users more reason than ever to switch to a flexible form factor.
