- More Galaxy S26 Edge battery details have leaked
- The phone could stick to lithium-ion technology
- A greater capacity of 4,200 mAh was predicted
Now that the Samsung Galaxy S25 Edge has been released, we can start thinking about what the Galaxy S26 Edge will offer – but it seems that one of the new features that are supposedly concerned with the phone will now be pushed back to a subsequent model.
Certification documents relating to the telephone observed by Samobile confirm that the 2026 handset will stick to the traditional Lithium-ion battery technology which has been supplying smartphones for a few decades.
Earlier this year, we talked that Samsung would jump to the higher silicon-carbon battery technology with the Galaxy S26 series, which offers larger capacities (and more time between loads) in batteries of the same size.
Now it seems that it does not happen – at least for the Samsung Galaxy S26 Edge, where the additional capacity would have been welcome. As we say in our review Galaxy S25 Edge, the battery life on the “is not great”.
Forward
However, the same regulatory certification indicates another type of battery upgrade: the Galaxy S26 Edge will be delivered with a capacity battery of 4,200 mAh, compared to the capacity of 3,900 mAh of the current model, such as rumors previously.
This should mean a little additional time between the charges, and I hope that Samsung will be able to set up additional hardware and software optimizations which mean that the battery life will not be concerned about 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 be no more model in 2026 – and three flagship products rather than four for the Galaxy S26 series.
The Samsung Galaxy S26 series should be launched in January 2026, if Samsung sticks to its usual schedule. Before that, we expect to see a new Galaxy S25 Fe phone and some Galaxy Tab S11 tablets announced next Thursday.
