Samsung's goal is to create a device with extensible screen that can suit the various types of mobile phone usages. However, battery capacity remains one of the main obstacles.

A Samsung launched its first folding phone in 2019 and has since been one of the most prolific companies in this segment. In addition to “high” folding phones, Samsung has also been betting on “flip” design and this year even presented a flexible screen model with a wider design.
The South Korean company seems to have no intention of sticking around and, as other rumors have pointed out, Samsung is developing a mobile phone with an extensible screen – which means that users will no longer have to open devices if they want access to a larger screen.
The possibility for Samsung to launch a mobile phone equipped with an extensible screen was corroborated by the Ice Universe page on social network X, which indicated that users can switch between proposals of 16:19 and 21:9 as they are doing.
“ Samsung is developing a mobile phone whose screen extends from 16:9 to 21:9. Some people prefer a wider screen, while others like the higher format. This design should accommodate both, allowing users to adjust proportions as they are doing. If Samsung can do it, it might be a very interesting solution”, can be read in the latest publication made by this page on X.
However, the author says that “battery capacity is the big challenge”. The reason is the mechanism that allows the screen to be extended, “which must require a considerable amount of internal space” and that would not allow the battery to have as high a capacity as would be desirable.
“ How much capacity could Samsung fit in there? Would it be enough autonomy with the screen fully extended? These are questions Samsung has to answer before this is a practical device for everyday life.”, write the Ice Universe page.
It is good to remember that the latest information that circulated about Samsung's plans for the folding market indicated that in 2027 the company plans to launch even more foldable than this year.
It is not yet known whether this folding mobile phone with extensible screen would be part of this batch, but if the mobile phone is still in development it is possible that the technology wants to play it safe and launch it only in 2028.
Samsung is developing a phone with a display that can extend from 16:9 to 21:9. Some people prefer a wide screen, while others like a taller form factor. This design could accommodate both, letting users adjust the proposals to suit what they’re doing. If Samsung can make it work, it could be a very appealing solution. Battery capacity is the big challenge, though. The sliding mechanics would take up a considerable amount of internal space, leading less room for the battery. How much capacity could Samsung fit inside? And would it deliver through battery life with the full extended screen? These are questions it needs to answer before this alley is a practical everyday device.
