Are you ready for the "thinnest folding machine in the world"?
Yes, ladies and gents, it looks like Samsung will snatch that crown away from Oppo... unless, of course, the razor-thin Find N5 receives an unusually early sequel with an even slimmer profile.

Fold 7 is today tipped to rock a 3.9mm (!!!) waist "after unfolding" and the same 8.9mm as its direct rival "after folding."
While the Oppo Find N5 measures 4.2mm unfolded and 8.9mm folded (which initially seemed like very hard-to-beat dimensions), theis today tipped to rock a 3.9mm (!!!) waist "after unfolding" and the same 8.9mm as its direct rival "after folding."
In case you're wondering, the Snapdragon 8 Elite powerhouse was previously rumored to measure 4.5mm and 9.5mm in thickness in its unfolded and folded state respectively, which would have already marked a big progress over the Z Fold 6 's 5.6mm and 12.1mm figures.

Going down to as little as 3.9 millimeters is simply mind-boggling, making the aforementioned 4,400mAh battery capacity feel like nothing short of an engineering miracle. Then again, the Oppo Find N5 somehow offers 5,600mAh juice, so I can totally understand if you'd rather see the

Fold 7 measure the same 4.5mm as its predecessor, for instance, while bumping the cell size to 5,000mAh or more.
As for the "thinnest foldable in the world" title, something tells me very few prospective buyers will care about that sort of "achievement", especially with brands like Oppo, Vivo, or Honor often excelling at quickly beating such (meaningless) records.

Don't forget about the Z Flip FE , aka Z Flip Xe , either, which is likely to settle for a significantly smaller battery compared to theand could thus (theoretically) reduce its bigger, costlier, and more sophisticated brother's profile as well.
If you were disappointed to find out earlier this week that the fast-approaching Galaxy Z Fold 7 is likely to keep its predecessor's battery size unchanged , the latest gossip on social media regarding Samsung's next big book-style foldable might make you radically reconsider your stance on the rumored 4,400mAh cell capacity.
