Samsung Unpacked 2024: Galaxy Z Fold7 Launches With Familiar Battery Size

Yesterday at Samsung’s highly anticipated Unpacked 2024 event, the company introduced the latest additions to its foldable lineup: the Galaxy Z Fold7, Galaxy Z Flip7, and Galaxy Z Flip7 FE. While the Galaxy Z Flip7 impresses with a notable battery capacity upgrade, the Fold7 retains the same 4,400 mAh battery as its predecessor, sparking debate and curiosity among tech enthusiasts worldwide.

The Reason Behind the Unchanged Battery in the Fold7

Many expected a bigger battery for the newest Galaxy Z Fold, given the device’s two large displays and the growing demands of power users. Responding to inquiries from SamMobile, Samsung explained that consumer feedback was the driving force; Flip users prioritized longer battery life, leading to a larger battery for the Flip7. For Fold7 users, the focus shifted to other vital improvements: advanced camera systems, a thinner and lighter build, and an expanded cover screen.

Features and Competitive Upgrades

In line with these priorities, the Galaxy Z Fold7 boasts significant hardware and design upgrades. The device is slimmer and lighter than ever, enhancing portability, and the wider external display improves usability. Enhanced camera hardware also provides a competitive edge against rival Chinese foldables—except in battery life.

Battery Limitations: Innovation Meets Practical Design

The Fold7’s unwavering 4,400 mAh battery is a direct result of Samsung’s emphasis on thinness and minimized weight. Industry experts believe that increasing battery size without compromising the Fold’s sleek profile may not be feasible until Samsung adopts new battery technologies, such as silicon-carbon (Si/C) cells already used by top Chinese brands. With current lithium-ion constraints, achieving greater capacity in the same space remains a challenge, especially as larger displays demand more power.

Market Relevance and Use Cases

Despite the unchanged battery, the Z Fold7 remains highly appealing to professionals, multitaskers, and early adopters seeking top-tier foldable technology and productivity features. Its refined design, improved camera system, and immersive displays ensure it stands out in a competitive market. However, power users who prioritize all-day battery life may hope for technology advancements in future generations.
