It’s happening. Samsung has officially adopted silicon-carbon batteries on its latest foldables, though you wouldn’t know that by looking at the spec sheet for the Galaxy Z Fold 8 or any other new devices.
In multiple press briefings this week, Samsung confirmed to members of the media that the Galaxy Z Fold 8, Z Fold 8 Ultra, and Z Flip 8 are all using silicon-carbon batteries.
Silicon-carbon batteries are well-known right now as the new technology makes it possible to squeeze much higher-capacity batteries into the same size. For other foldables, like the Razr Fold or Honor Magic V6, that means surpassing 6,000 mAh. For Samsung, it just means we’re finally getting a reasonably-sized battery.
Galaxy Z Fold 8 packs a 4,800 mAh battery into a smaller chassis than the Fold 7, which had a 4,400 mAh battery. Z Fold 8 Ultra jumps up to 5,000 mAh despite being thinner than the Fold 7, and both of those feats are likely thanks to silicon-carbon.
Samsung acknowledged the elephant in the room – the comparatively low specs here – by pointing to three pillars it was instead focused on. Performance, longevity, and safety. That last one is probably a big focus, given the scars left from history, but performance and longevity are also important. While silicon-carbon batteries are clearly the way of the future, they’ve only been around for so long, and there are still some rough edges to smooth out.
