As foldable phones are developed, battery capacity becomes a significant challenge. Since the batteries have such a unique form factor, companies must decide how to integrate them best. The batteries in these products are typically smaller than those in traditional smartphones. The upcoming Galaxy Z Flip7 appears to have a larger battery than its predecessor.

Samsung may include a battery with a typical capacity of 4,300 mAh in the Galaxy Z Flip7. In addition to the 2,985 mAh cell (EB-BF767ABY), the Korean giant uses a 1,189 mAh cell (EB-BF766ABY). Companies often market their devices’ batteries with approximations, despite the sum of both cells being under 4,300 mAh. Samsung Galaxy Z Flip6’s battery has a typical capacity of 4,000 mAh, while the sum of its internal batteries reaches 3,887 mAh.

Accordingly, the battery would be 7.5% bigger on the next-generation model. The device is rumored to have a larger foldable internal display. A higher-capacity cell was probably required for a longer battery life.

The Galaxy Z Flip7 could have an internal display measuring 6.85 inches, slightly larger than the 6.7-inch display on the current Galaxy Z Flip6. Likewise, the Z Flip6 will have a larger external display (4.3 inches). Samsung executives confirmed last year that the Exynos 2500 chip would be used in the phone.
