- More details of the Galaxy S26 edge battery have been leaked
- The phone could keep lithium -ion technology
- A greater capacity of 4,200 mAh has been predicted
Now that the Samsung Galaxy S25 edge is outside, we can start thinking about what the Galaxy S26 Edge will offer, but it seems that one of the new rumored features that supposedly arrives with the phone will now return to a later model.
The certification documents related to the phone seen by Sammobile confirm that the 2026 phone will remain with the traditional lithium -ion battery technology that has promoted smartphones during the last decades.
Earlier this year, there had been talk that Samsung would make the leap to the upper silicon carbon battery technology with the Galaxy S26 series, which offers greater capabilities (and more time between loads) in batteries of the same size.
Now it seems that this will not happen, at least for the Samsung Galaxy S26 Edge, where the additional capacity would have been very welcome. As we express in our Galaxy S25 EDGE review, the battery life on the “is not great” device.
Forward and up
However, the same regulatory certification points to a different type of battery update: the Galaxy S26 EDGE will apparently come with a 4,200 mAh capacity battery, compared to the capacity of 3,900 mAh of the current model, as previously rumored.
That should mean extra time between charges, and hopefully Samsung can gather some additional hardware and software optimizations that mean that battery life will not be something to worry about in the Galaxy S26 Edge.
There have also been rumors that the Galaxy S26 EDGE could effectively replace the Samsung Galaxy S25 Plus model, so there would not be a Plus model in 2026, and three flagships instead of four for the Galaxy S26 series.
The Samsung Galaxy S26 series should be launched in January 2026, if Samsung adheres to its usual schedule. However, before that, we hope to see a new Galaxy S25 FE phone and some Galaxy Tab S11 tablets announced next Thursday.
