- A new feature called “Battery AI” is rumored to be added to a future Galaxy S line, which could extend the phone’s battery life by 5% to 10% by managing background tasks more efficiently.
- Despite the unchanged battery capacity, the introduction of “Battery AI” could potentially offset criticism by improving overall battery performance without hardware changes.

Full Story
Oh, did you hear? There was this tweet floating around. Yeah, it spilled the beans on the Galaxy S25 Ultra’s battery life. So, Sammy’s planning to stick with the same ol’ 5,000mAh battery. And yep, it’ll support 45W fast charging, courtesy of @Sawyergalox’s sleuthing.
Originally, though, Samsung had this grand plan. They wanted to stack batteries, you know? That would’ve bumped up battery life and even cranked charging up to a zippy 65W. But, ah, plans change. Now they’re saying, “Let’s wait for 2026 and the Galaxy S26 Ultra.”
It’s kinda a bummer, right? The Galaxy S25 Ultra not getting a battery upgrade. But wait, there’s this other leaker, PandaFlash (hat tip to Wfcctech). He’s thrown a curveball our way. Talks about a secret sauce from Samsung called “Battery AI.” Supposedly, it’s this nifty trick that could add 5% to 10% more juice to your phone’s day.
Now, we’ve seen software that tries to stretch battery life before. Usually, it’s about choking the life out of your CPU/GPU or putting the 5G modem on a diet. But PandaFlash? He’s in the dark about how “Battery AI” actually works. He guesses it’s about kicking unnecessary background tasks to the curb.
Oh, and about when this “Battery AI” magic is supposed to hit the stage. PandaFlash didn’t spell it out, but he’s been chatting a lot about the 2025 Galaxy lineup. So, it’s not a wild guess to think the Galaxy S25, along with its siblings, the S25+ and S25 Ultra, might be the debutantes.
Considering Samsung’s already rolled out Galaxy AI on this year’s flagship, it’s not a leap to think “Battery AI” will join the party next year. Especially since the Snapdragon 8 Gen 4 and Exynos 2500 are expected to be the brains of the operation for the 2025 models.
If Samsung actually pulls this off next year, it could be a game-changer. Might even make folks rethink their grumbles about the Ultra’s battery staying put at 5000mAh since the Galaxy S21 dropped in 2021.
