A very reliable industry source — especially when it comes to news about upcoming Samsung products — confirmed that the Galaxy S26 Ultra will also have a disappointing battery. The phone will very likely come with yet another 5,000 mAh battery. And, if Samsung does increase the battery capacity, it will most definitely stay under 5,400 mAh.
Samsung is taking it very slow with improving the batteries on its phones, in my opinion. I know that the Galaxy Note 7 disaster probably still haunts Samsung, but the company’s competitors are stepping things up a notch. We have now seen various Chinese phones that have batteries as big as 7,000 mAh, usually using new dense battery technologies.
Unfortunately, it seems that Samsung does not see the importance of improved battery life. The new Galaxy S25 Edge only has a battery capacity of 3,900 mAh, something that a Samsung executive defended in a recent interview.
Like the Samsung Galaxy S25 Edge, Apple is also working on an iPhone 17 Air that it will announce later this year. As if this new obsession with slim phones with tiny batteries wasn’t bad enough, the Galaxy Z Fold 7 is reportedly going to have a measly 4,400 mAh battery as well.
