Samsung Rumored To Use Stacked Battery Technology For The Galaxy S24 Ultra, While Also Adding Fast-Charging Support
Samsung Rumored To Use Stacked Battery Technology For The Galaxy S24 Ultra, While Also Adding Fast-Charging Support-February 2024
Feb 12, 2026 1:14 PM

Samsung was previously reported to be working on an improved battery technology that would allow the Galaxy S24 series to feature a 10 percent larger capacitythan earlier models. While this is a step in the right direction, an updated rumor claims that this technology will remain exclusive to the Galaxy S24 Ultra, which is not surprising to hear.

Latest rumor also claims that the stacked battery technology might find its way to the Galaxy S24 Plus

The Korean giant is rumored to have started the prototyping phase of its stacked battery technology, which is based on EV, so some of the techniques used to mass produce those cells will likely be migrated to mobile devices. Unfortunately, RGcloudS on Twitter states that stacked batteries will only be found on the Galaxy S24 Ultra, with a small chance that these components will make their way to the Galaxy S24 Plus. It is likely that increased costs will prevent Samsung from bringing this technology to all three flagship models in 2023.

The tipster also notes in his series of tweets that the company is expected to start production at its Cheonan plant located in Seoul, but the manufacturing equipment necessary to start making these stacked batteries has yet to arrive at the Cheonan plant. RGcloudS also mentions that a pilot run of these stacked batteries will commence in China, but because these components will be produced in limited quantities, it is likely that the company will reserve them for the Galaxy S24 Ultra.

1/3

Stacked battery is on track, but limited

Most likely only for 24U & 24+

or just 24U

meanwhile,

apple used it on entire iP15 lineup

24U & 24+ have "rated" 5000 MaH

But 24U stacked structure is different

to make it cooler, they applied cooling gel. for 65W & stability https://t.co/8khM2oAToc

Aside from the advanced battery technology, there is also the possibility that Samsung incorporates 65W fast charging to the Galaxy S24 Ultra and Galaxy S24 Plus. To help remedy the overheating factor, cooling gel is said to be applied to the stacked battery. As for the advantages of this technology, we already talked about how adopting this method can help increase battery capacity, but incorporating it in smartphones will also help protect future devices by making them shock-resistant and reducing the risk of swelling.

Again, we recommend our readers treat this information with a pinch of salt, and we will be back with more details. Keep in mind that Samsung can alter its plans without any hint, so while we wish to see the stacked battery technology on the Galaxy S24 Ultra, there is a chance that the commercial units will miss out on this upgrade.
