Galaxy Z Fold 8 tipped for 5,000mAh battery boost, Galaxy Wide Fold also in the works

Samsung's Galaxy Z Fold series is set to receive a battery upgrade for the first time in several generations, according to new information from GalaxyClub. The upcoming Galaxy Z Fold 8 is expected to feature a total battery capacity of 4,854mAh, which Samsung will likely advertise as 5,000mAh - representing a 13% increase over the current 4,400mAh cell in the Galaxy Z Fold 7.

What's new in the Galaxy Z Fold 8 battery

The battery upgrade comes from two separate cells: one rated at 2,369mAh and another at 2,485mAh. This dual-cell configuration is standard for Samsung's book-style foldables, allowing for a more even distribution of weight and heat across the device. While the increase to 5,000mAh is welcome news, it still falls short of what competitors like Oppo, Motorola, and Huawei offer in their foldable devices.

Interestingly, the Galaxy Z Flip 8 is expected to skip this battery upgrade cycle, maintaining its current capacity. This suggests Samsung is prioritizing battery improvements for its larger foldable form factor where power demands are typically higher.

Galaxy Wide Fold joins the lineup

Alongside the Galaxy Z Fold 8, Samsung appears to be developing a more affordable alternative called the Galaxy Wide Fold. Testing has revealed a 2,393mAh battery that could combine for approximately 4,900mAh total capacity. This would position the Wide Fold slightly below the flagship Fold 8 but still above the current Fold 7.

The Wide Fold strategy mirrors Samsung's approach with its Galaxy Wide series of budget smartphones, potentially offering a more accessible entry point into the foldable market without the premium price tag of the flagship Fold series.

Charging speeds remain uncertain

Samsung has historically capped charging speeds at 25W for its Fold lineup, even as competitors push beyond 40W and 65W charging. However, the recently announced Galaxy Z TriFold supports 45W wired fast charging, raising questions about whether this technology will trickle down to the Fold 8.

The company's conservative approach to charging speeds has been a point of criticism, particularly given that faster charging could significantly improve the user experience for power users who need quick top-ups throughout the day.

How it compares to the competition

Even with the battery upgrade, Samsung's 5,000mAh capacity in the Fold 8 would still lag behind offerings from Chinese manufacturers. Devices like the Oppo Find N3 and various Motorola Razr models have pushed beyond 5,000mAh, while Huawei's Mate X series has featured even larger batteries.

The gap is particularly notable given that foldables typically have more internal space for batteries compared to traditional smartphones, thanks to their unique hinge designs and internal component layouts.

Who this upgrade is for

The battery increase will benefit power users who rely on their foldables for productivity tasks throughout the day. The larger capacity should provide better endurance for multitasking, media consumption, and productivity workflows that take advantage of the Fold's larger inner display.

For the Wide Fold, the slightly smaller but still improved battery capacity suggests Samsung is targeting users who want foldable functionality without the premium battery expectations of the flagship model.

Looking ahead

The Galaxy Z Fold 8 and Wide Fold are expected to launch in July alongside the Galaxy Z Flip 8. While the battery improvements are incremental rather than revolutionary, they represent Samsung's continued refinement of its foldable technology.

Whether the company will address charging speeds remains one of the biggest questions heading into the launch. Given the competitive pressure from Chinese manufacturers and the success of faster charging in Samsung's other product lines, an upgrade to at least 35W or 45W seems increasingly likely, though not yet confirmed.

The battery upgrades, combined with expected improvements in other areas like processor performance and display technology, suggest Samsung is taking a measured approach to evolution rather than revolution with its 2026 foldable lineup.
