Samsung phone battery upgrades remain cautious—here’s why

Samsung fans have been asking for years: When are we getting better phone batteries? Not just minor tweaks, but real, game-changing upgrades. Meanwhile, competitors like Xiaomi and OnePlus are pushing out devices with super-fast charging and next-gen battery tech. Samsung, on the other hand, seems stuck in neutral. And that’s not by accident.

A new insider report from PandaFlash X suggests the ghost of the Galaxy Note 7 still haunts Samsung. Back in 2016, the Note 7 was pulled from shelves after its batteries started swelling, overheating, and in some cases, catching fire. The fiasco led to a global recall and cost the company billions, not just in refunds, but in reputation.

That moment has shaped every battery decision Samsung’s made since.

Take the recently launched Galaxy S25 Edge. It’s a sleek, ultra-thin device, but the trade-off is obvious: battery capacity. Some had hoped Samsung would use high-density silicon-carbon cells to offset the size limitation. But those hopes were dashed at launch. Now we know why. The company is taking its time—painfully so—testing advanced chemistries to make sure history doesn’t repeat itself.

While brands like Xiaomi are showing off solid-state battery prototypes and pushing 120W fast charging in commercial phones, Samsung is sticking to safer, slower tech. It’s not that they can’t match these specs—they’re choosing not to—at least not yet.

While tech enthusiasts might feel that approach is outdated, it’s hard to blame them. No company wants to go through another Note 7 situation. So, when will we finally see real Samsung phone battery upgrades? Possibly soon. But not before they’ve tested the hell out of it.
