We’ve come across battery speculations about Samsung’s upcoming Galaxy S devices lately.
What you should know:
– Speculations suggest Samsung is exploring enhancements for its forthcoming Edge smartphone, possibly by introducing new “battery materials.”
– These innovative materials might deliver a “larger” overall capacity for the Galaxy S26 Edge’s battery, although the exact figures are uncertain.
– Further conjecture indicates the Galaxy S26 Edge could be even slimmer than the 5.8mm thickness of the S25 Edge.
– A report mentioned that Samsung was pursuing a new “SUS CAN” battery material to significantly enhance the capacities of its Galaxy phones.
There are some whispers suggesting Samsung is developing two upgrades for its sleekest smartphone slated for 2026.
The anticipated upgrades may enhance the Galaxy S Edge series’ attractiveness, according to Ice Universe on X (via SamMobile). The source supposedly can “confirm” that the Galaxy S26 Edge will boast a “larger battery” when Samsung launches it next year. Speculative reports suggest this expanded battery will be made possible by some new “battery material technology” that Samsung is reportedly considering.
It appears that Samsung is not backing down from its enthusiasm for creating slim (and even slimmer) devices.
The post on X asserts that Samsung is allocating resources to develop a Galaxy S26 Edge that is even more slender than the S25 Edge. The source did not provide any predictions for its battery capacity or thinner dimensions, so we’ll need to take this information cautiously for the time being.
Samsung introduced the S25 Edge, the fourth member of the S25 lineup, in May. We are likely still quite a while from a second-generation release, but there are some recent updates worth noting.
Gaining the Edge
Samsung’s Galaxy S25 Edge was launched with the “beyond slim” tagline, as the company truly emphasized the sleekness and slimness of slab phones. The device features a 6.7-inch display and a dual camera setup (200MP primary lens), but its most striking element was its 5.8mm thickness. The S25 Edge is thinner than the other devices in the S25 series; however, this came at the cost of its battery.
A trade-off was inevitable, and it appears that the device’s 3,900mAh battery was the result of thinness ambitions. Additionally, Samsung equipped the phone with a 25W wired charging adapter, which can reach 55% charge in thirty minutes.
A “larger battery” would unquestionably allow the device to last longer. The approach Samsung takes to achieve this is crucial. Some users on X speculate that Samsung might adopt the silicon-carbon approach for the S26 Edge. Similar rumors have surfaced earlier this year from South Korea, so that’s one angle of speculation.
A recent report suggests that Samsung has shifted its focus and is now actively pursuing a new battery material called “SUS CAN.” Reportedly, this material can “significantly” enhance a device’s battery capacity, although it’s unclear how much this could mean. It’s also been noted that SUS CAN could benefit future Galaxy phones by providing greater energy density and faster charging speeds.
