As it turns out, the new Galaxy Z Fold 8 won’t look anything like the Z Fold 7 and will be wider. The true successor to the “seventh” will be the Galaxy Z Fold 8 Ultra smartphone. According to a leak, it will retain the familiar design but gain a larger battery and support faster charging. All the details come from an insider, so they should be treated as rumors rather than official specifications.

This is the smartphone that will become the successor to the Galaxy Z Fold 7
Samsung Galaxy Z Fold 8 Ultra Technical Specifications
The source of the information is well-known insider Ice Universe, who regularly leaks data about Samsung devices. According to him, the Galaxy Z Fold 8 Ultra will maintain a weight of around 215 grams and nearly the same dimensions as the Galaxy Z Fold 7. In other words, the new device will feel the same in the hand as the current model.
There are two main changes. First, the battery will grow to 5,000 mAh compared to 4,400 mAh in the Galaxy Z Fold 7. Second, it will feature 45W charging support (the current model is limited to 25W wired charging). According to the same data, the regular Galaxy Z Fold 8 will also get the same charging speed. These are still unconfirmed figures, but if they’re accurate, the combination of a larger battery and faster charging addresses the two main complaints about foldable smartphones: short battery life and slow recharging.
The Thinnest Android Smartphone
When unfolded, the thickness will be 4.1 mm, and the overall dimensions will remain the same as the Galaxy Z Fold 7. This means the body won’t get thicker or larger despite the bigger battery inside.

The smartphone will be incredibly thin
For a foldable smartphone, this is an important detail: manufacturers have been fighting for every millimeter for years because these devices are still noticeably thicker than regular phones when folded. If Samsung can fit a bigger battery into the same body, that would be careful engineering work, not a marketing gimmick.
Differences Between Galaxy Z Fold 8 Ultra and Z Fold 7
In short, the Galaxy Z Fold 8 Ultra is described as a Galaxy Z Fold 7 with a bigger battery and fast charging. A new processor and some other improvements are also mentioned, but without specifics. In practice, this means the following:
- the smartphone should last longer without needing to be plugged in thanks to the 5,000 mAh battery;
- recharging will be noticeably faster thanks to 45W instead of 25W;
- in the hand and in the pocket, the device will feel the same as the Galaxy Z Fold 7.
For those already using the Galaxy Z Fold 7, the reason for an urgent upgrade is debatable: the design is the same, and the improvements mainly concern battery life. However, for owners of older foldable models or those just considering the format, these changes could be the deciding factor. If you’re used to classic flagships like the Samsung Galaxy S26, the foldable format is still a different usage scenario with a large inner screen.
Galaxy Z Fold 8 Ultra Release Date
According to rumors, both smartphones will launch in July, with July 22 mentioned as the expected date. The presentation is supposed to be held in London, but Samsung has not officially confirmed any of this, and the announcement date remains at the level of speculation.

The new foldable is expected to launch as early as July 22
So it’s best to take all the specifications with a grain of salt. Before the official announcement, the battery, charging, and thickness figures could change, and the model names could change even more so, considering that Samsung has noticeable confusion with naming its foldable devices this generation. If you’re choosing between the company’s current flagships, it’s wiser to focus on already released models and real reviews rather than rumors about upcoming devices.
The bottom line is simple: the leak looks plausible and targets the two weak points of foldable smartphones — battery life and charging speed. But for now, this is just an insider report from Ice Universe, and until the July presentation, there’s no need to rush to conclusions or, especially, to make a purchase.
