Will Samsung EVER use Silicon-Carbon batteries to make phones lighter?

📖Discussion📕🖊️

We all know the pain of dropping a 230g flagship on your face in bed. Phones have become literal bricks, mostly due to bulky Lithium-Ion batteries.

​Meanwhile, Honor and Xiaomi are killing it with Silicon-Carbon (Si-C) batteries. By replacing graphite with silicon, they get much higher energy density—meaning phones can finally be thinner, lighter, and still pack 5,500+ mAh.

​Rumors show Samsung SDI is developing them, but they keep skipping them for the Galaxy flagships due to high production costs.

​What do you think?

Is there any chance Samsung will finally bite the bullet and use Si-C tech to drop the weight of their phones?

Or are we stuck carrying bricks forever?
