Samsung's Galaxy Z TriFold received a significant battery upgrade through an unofficial modification. The Strange Parts YouTube channel replaced the original 5,600 mAh battery with Honor's Si/C battery technology from the Magic V6. This increased the trifold's total capacity to 9,600 mAh, representing a 71% improvement over Samsung's original specifications.

Samsung continues to avoid Si/C batteries in its foldable lineup, even in 2026, while competitors like Honor embrace the technology. The 5,600 mAh capacity of Samsung's flagship trifold trails behind other folding smartphones, many of which now feature batteries in the 6,000 mAh range.

The battery swap demonstrates the potential of Si/C technology in enhancing user experience despite manufacturer limitations. While Samsung hasn't embraced this approach, the 71% boost proves the viability of third-party modifications for consumers seeking extended battery life in their premium foldable devices.
