- Samsung Galaxy S26 series could use silicon-carbon batteries
- This should allow for a 10-15% increase in capacity.
- The Samsung Galaxy S26 Ultra could have a battery of up to 5,750 mAh
The Samsung Galaxy S25 series is almost here, but reports suggest its batteries won’t be any bigger than those in last year’s phones. So if you’re hoping for longer battery life, you might want to wait for the Samsung Galaxy S26 series, which could have much larger batteries.
According to @Jukanlosreve, citing leaker @UniverseIce, the Samsung Galaxy S26 series will use silicon-carbon batteries. This type of battery has recently started to arrive in phones, such as OnePlus 13, Honor Magic 7 Pro and Xiaomi 15 Pro that already have silicon-carbon batteries.
Those three phones have much larger batteries than most phones, at 6000 mAh, 5850 mAh and 6100 mAh respectively, and that’s no coincidence, as this type of battery allows for around 10-15% more density of energy, so a larger capacity battery can take up the same amount of space.

Up to around 5,750 mAh
The source does not say what capacities we can expect from the Samsung Galaxy S26 series batteries, but for reference, the Samsung Galaxy S24 has a 4000 mAh battery, the Samsung Galaxy S24 Plus has a 4900 mAh one and the Samsung Galaxy S24 Ultra It has a 5000 mAh battery. We expect the same from the Samsung Galaxy S25 series.
So, assuming a 10-15% increase, we could be looking at 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 Ultra.
These are large enough increases that these phones can last much longer between charges than the current Galaxy S models, so if battery life is a priority for you, it may be worth the wait.
Of course, this is just a rumor for now, and a very early one at that, so while the source is reliable, we wouldn’t count on that happening.
Furthermore, although rumors suggest that the battery capacity of the Samsung Galaxy S25 line will not be greater than that of the S24 series, we won’t be sure of this until these phones launch on January 22. And even if there are no changes to capacity, they could still offer improved life through software optimizations.
So you may not have to wait until 2026 for a longer-lasting Samsung smartphone, but in any case, we’ll have a clearer idea soon.
