Samsung is expected to announce the Galaxy Z Fold4 this Fall and it will bring a bunch of design changes. According to the leakster Ice Universe, those will result in significant weight reduction and the new foldable will tip the scales at under 260g.
Detailed specs of the upcoming phone are yet to arrive, so at this point we can only speculate on how the weight loss will be achieved. The battery capacity will be unchanged, while bezels will be trimmed slightly, but probably not enough to account for the 5% difference. A new hinge design may be involved, but there’s no solid evidence.
One other means the Galaxy Z Fold4 may drop some weight is that if it replaces the aluminum body and hinge with some form of plastic, however that is an unlikely answer as a result of it could lose its premium look. Both means, we’re looking out for extra leaks within the upcoming months that ought to assist us type a clearer image.
