A recent report said that the world’s first smartphone with a rollable, aka extendable, aka slideable display is coming next year. Samsung will be the company that will make it, and now we’ve received some additional information about it.
Display on Samsung’s first rollable phone will extend from 16:9 to 21:9 aspect ratio
Ice Universe, one of the best-known and most reliable tipsters around, confirmed the news. He said that Samsung is developing a phone with a display that can “extend from 16:9 to 21:9,” as he’s referring to the display’s aspect ratio.
The tipster did not say that the phone is coming in 2027, even though it probably is. He did, however, say that the battery capacity is a big challenge for Samsung. That is kind of logical, though, so it’s not a surprise.
The sliding mechanism does take up a considerable amount of internal space, which, in turn, leaves less room for the battery. While he did not mention it, this could be the company’s first phone with a pure silicon-carbon battery.
Samsung has had several phones thus far (the Galaxy Z Fold 8 series) that dabble in silicon-carbon tech, but they don’t feature silicon-carbon batteries per se. Those are still technically Li-Ion batteries.
Well, in order to accommodate the sliding mechanism, Samsung may be forced to go down the silicon-carbon route, as those batteries take less physical space.
The durability of the sliding mechanism is also a concern
In a comment to Ice Universe’s post, Ross Young, another tipster, shared another concern. He said that the durability of the sliding mechanism is also a big concern for the company.
I actually recently wrote an editorial on the topic of Samsung’s rollable phone, and questioned whether we actually need it. Foldable smartphones have become so good that releasing a rollable phone at this point in time may not be the best idea. Only time will tell, though.
