- The collapsible iPhone could be 4.8 mm thick when unfolding
- That would make it thicker than the 4.2 mm thick Samsung Galaxy Z Fold 7
- Being thicker can, however, come with some benefits
One of the more impressive things about the Samsung Galaxy Z Fold 7 is just as slim it is, at only 4.2 mm thick when unfolded. It is actually so slim that the very rumored foldable iPhone may not be able to match it, despite the fact that this device is probably not launching until 2026 at the earliest-at what time Samsung may have an even thinner folding.
According to Leaker Setsuna Digital (via Apple Insider), the folding iPhone will be 4.8 mm thick when unfolded, which although it is certainly slim, is a full 0.6 mm thicker than the Samsung Galaxy Z Fold 7.
Still, this would have the iPad Pro 13-inch (2024) beat as it is 5.1 mm thick. It would also hit 7.8 mm iPhone 16, so this could still be one of Apple’s slimmest devices – at least when unfolded.
When we are folded, we assume it will be at least twice as thick as when unfolded, but it is unlikely that it is exactly twice as thick as the folded dimensions of phones are usually more than twice the unfolded, with the Galaxy Z Fold 7 for example 8.9 mm thick.
Still, this rumor may be inaccurate – the source has a mixed track record, and we have heard other thicknesses performed earlier, with a previous leak pointing to a 4.6 mm thickness.
Thinner is not always better
Either way, however, it sounds like Apple’s upcoming phone is likely to be thicker than the Samsung Galaxy Z Fold 7, but that’s not necessarily a bad thing. Yes, this means that when folded closed, this device may be a little thick, but it can also give way to a larger battery or better cameras than the phone might otherwise have.
We would think it is a change that many people would probably take, so for now we are not too concerned that Apple may not win this particular match.
But with the folding iPhone that probably won’t land until the end of 2026, we would still take all rumors about it with a pinch of salt for now.
