Samsung Galaxy Z Fold 8 Ultra Tipped With 5,000mAh Battery and 45W Charging

Samsung is preparing to expand its foldable lineup with a new tier this year. The Galaxy Z Fold 8 Ultra is expected to launch alongside the standard Galaxy Z Fold 8, and early reports from SamMobile point to hardware upgrades targeting three areas where the current flagship foldable has drawn the most criticism: battery life, charging speed, and display crease.

Battery capacity is the headline spec. The Galaxy Z Fold 8 Ultra is reported to carry a 5,000mAh cell, up from the 4,400mAh in the Galaxy Z Fold 7. That’s a 600mAh increase — not transformative on paper, but relevant in a form factor where thinness and the foldable hinge have always pushed battery size down. The Fold 7’s battery life has been adequate rather than excellent, and the jump to 5,000mAh could push the Ultra closer to the all-day endurance standard people expect at this price point.

Charging speed is getting a larger proportional upgrade. The Fold 8 Ultra is tipped to support 45W super fast charging, compared to the 25W currently offered on Samsung’s foldables. At 45W, filling a 5,000mAh battery takes considerably less time than the current setup allows. Samsung’s non-folding flagships — the Galaxy S25 Ultra, for example — have supported faster charging for a while, and the gap between the S and Z series on this front has been a consistent complaint from foldable users.

The display crease is the most technically interesting reported improvement. Every foldable phone has a visible crease at the fold point, and while Samsung has reduced it with each generation, it remains noticeable — especially under direct light. Reports for the Fold 8 Ultra suggest the company is targeting a near-crease-free result this time around. If that holds up when the device actually ships, it would be the most meaningful display improvement in the Fold line since Samsung introduced the first Galaxy Z Fold, and almost certainly the lead marketing point for the device.

Samsung hasn’t confirmed pricing or an exact launch date. The “Ultra” label the company uses on its S series phones implies a premium above the standard Fold — the Galaxy Z Fold 7 launched at around $1,799 in the US, so the Fold 8 Ultra could push past $2,000. That would put it in direct competition with Google’s Pixel 10 Pro Fold and above most of the foldable field in terms of price.

The Galaxy Z Fold 8 Ultra would be the first time Samsung has run a dual-tier foldable strategy at launch — offering both a standard and an Ultra version simultaneously rather than a single flagship. Whether that segmentation works depends on whether the Ultra’s improvements justify the price gap over the base Fold 8.

Samsung hasn’t announced when it plans to officially reveal the Galaxy Z Fold 8 series, but the company typically holds its Galaxy Unpacked event in July for new foldables. A summer reveal with a late July or early August shipping date would follow the same pattern as previous years. Watch for teaser posts on Samsung’s official channels and leaks from the supply chain as the date approaches.
