- Samsung Galaxy S26 series could use silicon-carbon batteries
- This should allow a capacity increase of 10 to 15%
- The Samsung Galaxy S26 Ultra could then have a battery of up to around 5,750 mAh
The Samsung Galaxy S25 series is almost here, but reports suggest their batteries won’t be any bigger than last year’s phones. So if you’re hoping for improved battery life, you might want to wait for the Samsung Galaxy S26 series, which could have much bigger batteries.
According to @Jukanlosreve – citing leaker @UniverseIce – the Samsung Galaxy S26 series will use silicon-carbon batteries. This type of battery has only recently started to make its way into phones, with the OnePlus 13, Honor Magic 7 Pro and Xiaomi 15 Pro already having silicon-carbon batteries.
All three of these phones have much larger batteries than most handsets, at 6,000 mAh, 5,850 mAh, and 6,100 mAh respectively, and that’s no coincidence, as this battery type allows for approximately 10-15% higher, so a larger capacity battery can take up the same amount of space.

Up to approximately 5,750 mAh
The source doesn’t say what capacities we can expect from the Samsung Galaxy S26 series batteries, but for reference, the Samsung Galaxy S24 has a 4,000 mAh battery, the Samsung Galaxy S24 Plus has a 4,900 mAh one, and the Samsung Galaxy. The S24 Ultra has a 5,000 mAh battery. We expect the same from the Samsung Galaxy S25 series.
So, assuming a 10-15% increase, we could be looking at a battery between 4,400 mAh and 4,600 mAh for the Samsung Galaxy S26, between 5,390 mAh and 5,635 mAh for the Galaxy S26 Plus, and between 5,500 mAh. and 5,750 mAh for the Samsung Galaxy S26. Samsung Galaxy S26 Ultra.
These are significant enough increases that these phones could last much longer between charges than current Galaxy S models. So if battery life is a priority for you, it might be worth the wait.
Of course, this is just a rumor for now, and a very early one, so even if the source is reliable, we can’t expect it to happen.
Additionally, while rumors suggest that the battery capacities of the Samsung Galaxy S25 series won’t be higher than those of the S24 series, we won’t know for sure until these phones launch on January 22. And even if there is no change in capacity, they could still offer improved lifespan through software optimizations.
So there may be no need to wait until 2026 to have a more durable Samsung smartphone, but in any case we’ll have a clearer idea soon.
