Samsung details the journey of making the Z Fold8 and Z Fold8 Ultra thinner and lighter
Samsung engineers detailed the technical challenges of reducing the weight and thickness of the Galaxy Z Fold8 and Z Fold8 Ultra. The process involved optimizing hundreds of components, including battery design and material science, to maintain performance while slimming the device.
Why it matters
Engineering breakthroughs in foldable devices are essential for improving user ergonomics and competing in the high-end smartphone market.
The original Galaxy Fold weighed a hefty 276g – and that isn’t even the heaviest Fold. That honor goes to the Z Fold2 , which tipped the scales at 282g. And yet Samsung’s latest book-style foldable is only 201g.
Okay, to be fair, this refers to the Galaxy Z Fold8 , which has a smaller form factor than previous Folds. This is the story of how Samsung engineers made their Z foldables both lighter and thinner.
The Galaxy Z Fold7 achieved an ambitious goal. Samsung asked “Could a foldable be lighter than a bar-type flagship smartphone?” and then found a way to do it – the Z Fold7 weighs 215g, which is 3g less than the Galaxy S25 Ultra.
