Over time, three priorities became clear: developing larger, more immersive displays, designing thinner and lighter devices without compromising durability, and offering ultra performance while preserving the unique advantages of the foldable form factor. Delivering all three became the defining engineering challenge behind the latest Galaxy Z series<\/a>.<\/p>\n

Q. Samsung describes foldable innovation as engineering one connected system. What does that mean in practice?<\/p>\n

With foldables, every component is interconnected. Making a device thinner, for example, means redesigning the display, hinge, battery, thermal system, and internal architecture together. Rather than optimizing individual parts separately, we engineer the entire device as one connected system. This end-to-end engineering philosophy extends from component design and materials to manufacturing, validation, and the final product experience \u2014 allowing engineering advancements to become improvements people experience every day.<\/p>\n

\"Samsung<\/p>\n

Samsung engineered each of the latest foldables as one connected system to bring about key improvements for users.
\nQ. The new Galaxy Z series<\/a> introduces Flex Titanium technology. What engineering challenges did it solve?<\/p>\n

Our goal was to make foldables thinner and lighter without compromising the viewing experience or durability. That required us to rework the display support structure protecting the ultra-thin OLED panel while preserving the flexibility needed for repeated folding.<\/p>\n

Used in demanding industries such as aerospace, titanium offered the strength and resistance against permanent deformation essential for a foldable display. But selecting the material was only the beginning. The real challenge was developing the processing, structural design, and manufacturing expertise needed to make titanium suitable for repeated folding.<\/p>\n

\"Flex<\/a><\/p>\n

Flex Titanium technology makes the display thinner and more durable while reducing crease visibility.<\/p>\n

Flex Titanium combines two titanium-based elements. The titanium plate beneath the display serves as the primary structural support, helping absorb pressure and impacts from both the front and rear of the device. A precision-engineered lattice structure \u2014 created through a hybrid manufacturing process \u2014 allows the plate to remain flexible while maintaining structural strength. Beneath the display panel, the titanium-alloy film provides the strength, flexibility, and elastic recovery needed to support repeated everyday folding, even at a thickness of just tens of micrometers \u2014 roughly one-third the thickness of a human hair.<\/p>\n

\"Flex<\/a><\/p>\n

Flex Titanium technology features an exceptionally thin titanium-alloy film and precision-engineered titanium plate.<\/p>\n

Together, these innovations strengthened the display support structure while reducing display module thickness by 10%, creating additional space for the battery, thermal system and camera. For users, that translates into a thinner, lighter device with a flatter display and reduced crease visibility.<\/p>\n

Q. How did Samsung reinvent the battery system for the latest Galaxy Z series<\/a>?<\/p>\n

Users expect longer battery life, faster charging and a thinner foldable \u2014 without compromising safety, stability, or long-term reliability. Meeting those expectations required reengineering the battery system, not simply increasing battery capacity.<\/p>\n

We introduced a silicon-carbon anode to improve energy density, but the innovation extends beyond the anode. Because silicon-carbon materials are more reactive, maintaining long-term stability under high-voltage conditions meant optimizing the entire battery system. Improvements to the display structure also created additional internal space, allowing us to redesign the battery system while preserving a slimmer form factor. As a result, Galaxy Z Fold8 Ultra features a 5,000 mAh battery.1<\/a><\/p>\n

The same philosophy shaped charging. Rather than applying a single solution across the lineup, we developed charging architectures tailored to each foldable form factor. Galaxy Z Fold8 Ultra<\/a> and Galaxy Z Fold8<\/a> use a dual-path charging architecture that helps distribute power more efficiently across the battery system, enabling faster, more stable and reliable charging while improving heat management. This supports 45 W fast charging,2<\/a> enabling Galaxy Z Fold8 Ultra<\/a> to reach a 67% charge in 30 minutes.3<\/a> For Galaxy Z Flip8<\/a>, the charging architecture was separately optimized for the unique spatial and thermal requirements of its compact form factor.<\/p>\n

Q. To ensure foldables can withstand years of everyday use, how does Samsung validate durability before bringing a device to market?<\/p>\n

For us, durability isn\u2019t just about design \u2014 it must be proven through testing. We validated the complete foldable system under conditions that reflect how people use their devices. The latest Galaxy Z series<\/a> was subjected to more than 100 reliability validation tests covering real-world conditions including drops, repeated folding, pressure, moisture, and debris. Our goal was to understand how the complete device performs in everyday use, identify potential issues before they reach customers and build foldables people can trust.<\/p>\n

Q. Looking back at the entire development process, how would you describe Samsung\u2019s approach behind the Galaxy Z series<\/a>?<\/p>\n

Everything starts with the user. Over seven generations, we\u2019ve transformed user insights into innovations in materials, components and the overall device experience. That philosophy continues to guide the Galaxy Z series<\/a> \u2014 delivering foldables that are thinner, more durable, more capable, and more intuitive year after year.<\/p>\n
