A recent experiment has demonstrated how new battery technology could dramatically increase the capacity of foldable smartphones. The Samsung Galaxy Z TriFold, originally launched with a 5,600mAh battery, was upgraded to an impressive 9,600mAh through the use of advanced silicon-carbon (Si/C) battery cells.
The Galaxy Z TriFold was unveiled by Samsung in December as the company’s first triple-folding smartphone. Despite its innovative design and premium specifications, the device’s 5,600mAh battery capacity was considered modest compared with many modern smartphones. Some conventional smartphones and foldable devices now feature batteries approaching or exceeding the 6,000mAh mark.
To demonstrate the potential of newer battery technology, the YouTube channel Strange Parts conducted a modification experiment on the Galaxy Z TriFold. The creators replaced the phone’s original battery cells with silicon-carbon batteries sourced from the Honor Magic V6 foldable smartphone.
Silicon-carbon battery technology is becoming increasingly popular among smartphone manufacturers because it allows higher energy density compared to traditional lithium-ion batteries. This means manufacturers can fit larger battery capacities into the same physical space without increasing the device’s size.
After installing the new Si/C battery cells, the modified Galaxy Z TriFold achieved a total battery capacity of approximately 9,600mAh. This represents a massive increase of around 71 percent compared with the device’s original battery capacity.
The experiment highlights how emerging battery technologies could significantly extend the battery life of future foldable smartphones. Larger batteries are particularly important for foldable and tri-fold devices because their larger displays and complex mechanisms often consume more power than traditional smartphones.
However, the upgrade carried out by the YouTube creators was purely experimental and not intended for everyday users. Replacing smartphone batteries with unofficial components can be risky and may damage the device or cause safety issues.
Still, the results demonstrate the potential advantages of silicon-carbon battery technology. As more manufacturers adopt this approach, future foldable smartphones could offer significantly longer battery life without increasing thickness or weight.
For now, Samsung continues to rely on conventional battery technology, but experiments like this suggest that high-capacity batteries could soon become a key feature in next-generation foldable devices.
