Samsung hasn’t exactly been aggressive with battery upgrades on its smartphones. The Galaxy Z Fold series, in particular, has been sitting on the same 4,400mAh capacity for years now, even as competitors have been pushing much higher numbers for some time. That might finally be about to change.
A new report from GalaxyClub suggests the upcoming Galaxy Z Fold 8 could see a noticeable bump. The device is said to use a dual-battery setup with a combined rated capacity of around 4,854mAh, split between two cells (2,369mAh and 2,485mAh). As usual, Samsung will likely market that as a 5,000mAh battery, which would be roughly a 13% increase over previous models.
The Fold 8 is expected to launch in July, alongside the Galaxy Z Flip 8. Interestingly, the Flip doesn’t seem to be getting the same treatment this time, with leaks suggesting its battery will remain unchanged. So the focus, at least for now, is clearly on the Fold.
Even then, Samsung still isn’t leading the pack. Some competitors are already pushing 6000mAh+ capacities. So while this is progress, it’s more of a catch-up move than a leap ahead.
There’s also a small twist in the leak. Another battery, rated at 2,393mAh, has reportedly been spotted in testing. It’s not confirmed what it belongs to, but speculation points to a possible “Galaxy Wide Fold”, a different take on the Fold design that could launch around the same time.
If that turns out to be real, it might come with a combined capacity somewhere near 4,900mAh. Slightly below the Fold 8, but still better than what Samsung has been offering so far. The idea seems to be a wider form factor, possibly making the device feel more tablet-like when opened up.
All of this points to Samsung slowly responding to pressure in the foldables space. It’s not a dramatic overhaul, but the battery upgrade alone could make the Fold 8 a bit more practical for everyday use.
There’s still a lot we don’t know, but with the expected July 2026 launch window getting closer, more details should start to surface soon.
