Samsung’s Fold 8 battery leak brings me joy but also a bit of annoyance.
Samsung hasn’t significantly modified the Galaxy Z Fold’s battery in recent years, but that may change soon. Since 2021, the company has consistently utilized a 4,400mAh battery, while rivals like Honor and OPPO have succeeded in integrating larger batteries into sleeker foldable devices.
According to fresh information discovered by GalaxyClub, the upcoming Galaxy Z Fold 8 might feature a 5,000mAh battery, a clear upgrade from the 4,400mAh cell present in the Galaxy Z Fold 7 and various versions prior.
This may not appear to be a drastic alteration, but it would represent the largest battery Samsung has ever included in a standard Fold model. The company has maintained a similar battery size for many years. The Galaxy Z Fold 2 contained a 4,500mAh battery, and since the Fold 3, the battery has hovered around 4,400mAh, even as display and performance demands have risen.
Why foldables utilize dual batteries
Similar to previous Fold versions, the Galaxy Z Fold 8 will likely employ a dual-battery configuration. This design is essential for foldable smartphones. Each segment of the device possesses its own battery, working in unison as one system.
The leaked specifications indicate one battery with a rating of approximately 2,369mAh and the other about 2,485mAh, yielding a combined rated capacity of around 4,845mAh. Samsung would probably promote that as a typical 5,000mAh capacity, which is common practice for smartphone batteries.
If these figures are accurate, that’s roughly a 13 to 14 percent rise compared to the Fold 7. While it’s not a substantial leap, it should contribute to improved daily battery longevity. Conversely, some Chinese brands are already providing foldable devices with significantly larger batteries, sometimes 6,000mAh or more, in phones with similar thinness.
Meanwhile, the Galaxy Z Flip 8 may not receive a battery upgrade this year. This could be disappointing for fans of clamshell foldables.
The battery isn’t the sole aspect anticipated to evolve in Samsung’s forthcoming foldable. Initial leaks suggest that the Galaxy Z Fold 8 could feature a 6.5-inch cover screen, a larger 8-inch foldable OLED display, a Snapdragon 8 Elite Gen 5 for Galaxy chip, and a minimum of 12GB of RAM along with 256GB of storage.
Software enhancements may also contribute to extended battery life. The device is expected to operate on Android 17 with One UI 9, potentially making it one of the first Samsung products to launch with that version immediately.
One element that the leaks have not clarified is the charging speed. Samsung’s Fold phones have utilized 25W wired charging for several years, while other leading phones, including Samsung’s own Galaxy S26 Ultra, can now charge at significantly higher rates.
Samsung is anticipated to unveil its next foldable phones around mid-2026, likely alongside the Galaxy Z Flip 8 and possibly other new foldable designs.
Android Central’s Perspective
I’m pleased to see Samsung finally enhancing the Fold’s battery. For a device designed for multitasking and extensive screen usage, battery life ought to be a priority. A 5,000mAh battery should translate to fewer mid-day charges for users who make use of the inner display as Samsung intends. Nevertheless, it’s evident that other brands already present foldables with considerably larger batteries, making this upgrade feel more like Samsung merely trying to keep pace. I value the improvement, but truthfully, this change should have occurred a few years back.
