Samsung Galaxy Z Fold 8 rumours suggest bigger battery and tablet-like display

Samsung’s next generation of foldable smartphones is already generating buzz months ahead of its expected launch, thanks to a fresh round of leaks hinting at battery upgrades and possible design changes.

While foldable phones have steadily improved over the years, battery life and charging speeds remain key concerns for many users. Now, newly surfaced information suggests that Samsung may be planning to push the battery capacity of its flagship foldable further, though not every aspect of the device may see a dramatic upgrade.

The leaks also point towards a possible shift in design strategy for Samsung’s foldable lineup, with reports hinting at a wider form factor aimed at improving everyday usability.

A report from GalaxyClub suggests that the upcoming Galaxy Z Fold 8 could arrive with a 5,000mAh battery. If this information proves accurate, it would mark roughly a 13 per cent increase compared with the battery capacity of the Galaxy Z Fold 7.

That would make it the largest battery ever used in Samsung’s Galaxy Z Fold series so far, although it would still fall short of the 5,600mAh battery reportedly featured in the Galaxy Z TriFold.

It remains unclear whether Samsung will also introduce faster charging with the Fold 8.

Previous Galaxy Z Fold models have been capped at 25W wired fast charging. However, the company may finally consider an upgrade, possibly bringing support for 45W or even 60W charging. Such a move would align the foldable more closely with Samsung’s flagship Galaxy S26 Ultra, which already supports 60W fast charging.

Samsung Galaxy Fold 8: What to expect

Battery upgrades may not be the only change Samsung is preparing for its next foldable.

Another leak, shared on the Chinese social media platform Weibo by tipster Digital Chat Station, suggests that Samsung could be developing a wider foldable smartphone with a slightly different display strategy.

According to the tipster, the device may feature a 7.6-inch main screen when unfolded. That would technically be smaller than the 8-inch inner display seen on the Galaxy Z Fold 7, but the difference may come down to a redesigned aspect ratio.

Earlier reports have suggested Samsung could experiment with a shorter, wider shape that resembles a tablet-style 4:3 format. Such a layout could make the cover display easier to type on and offer a more comfortable experience for reading, browsing and watching videos when the device is opened.

The broader foldable phone market is also expected to become more competitive in the coming years.

Industry insiders believe that Samsung and Apple could lead the global foldable smartphone segment by 2026. Meanwhile, companies such as Huawei and other Chinese manufacturers may dominate the category within China.

If those predictions prove correct, Samsung’s upcoming foldable devices will likely play a key role in determining how the next phase of the foldable smartphone race unfolds.
