Samsung’s next-generation foldable smartphones—the Galaxy Z Fold 7 and Galaxy Z Flip 7—are shaping up to be thinner, sleeker, and more powerful than ever. Thanks to a recent UL Demko certification leak, we now have a clear look at their battery specifications. While there are some encouraging upgrades, there are also trade-offs to consider, especially for battery longevity and daily usage patterns.
For US audiences eagerly awaiting Samsung’s July announcement, understanding these battery changes can help set realistic expectations. We’ll break down what the certifications reveal, compare the new models to last year’s Fold 6 and Flip 6, and explain what these battery tweaks mean for real-world performance and charging habits in the United States.
Battery Specifications Revealed: A Mix of Good and Bad News
According to the UL Demko documents, the Galaxy Z Fold 7 continues Samsung’s dual-cell battery design with two modules rated at 2,126 mAh and 2,146 mAh, for a combined capacity of 4,272 mAh. This total is essentially on par with the Fold 6’s rated 4,273 mAh, though Samsung previously marketed a “typical” capacity of 4,400 mAh for that model.
On the flip side, the Galaxy Z Flip 7 appears to bump up its cell sizes over the Flip 6. It now features two battery modules of 1,189 mAh and 2,985 mAh, totaling 4,174 mAh. That’s a noticeable increase over the Flip 6’s 3,887 mAh battery (2,790 mAh + 1,097 mAh), which Samsung labeled as 4,000 mAh typical. These figures suggest the Flip 7 may finally close the battery gap that foldable clamshell designs have traditionally struggled with.
Detailed Look at the Galaxy Z Fold 7 Battery
Despite shaving even more millimeters off the Fold’s thinness, Samsung has maintained nearly the same battery capacity as last year. The slight difference between the two cells’ sizes—just 20 mAh—points to a more balanced power delivery approach, which could improve heat distribution and longevity.
In practical terms, US users can expect similar endurance to the Fold 6, which delivered around a full day of moderate use (email, web browsing, social media) and 6–7 hours of screen-on time on the primary display. If Samsung’s “typical” rating again exceeds the summed cell capacities, we may see a claimed 4,400 mAh figure, too, which translates to marginal gains under real-world conditions.
Galaxy Z Flip 7 Ups the Ante with a Bigger Cell
The Flip 7’s battery upgrade is arguably more significant. By expanding the larger cell from 2,790 mAh to 2,985 mAh and boosting the smaller one, Samsung promises a typical capacity rating upward of 4,300 mAh. That could close the gap with many non-folding flagship phones in the US market.
Consumers who have struggled with the Flip 6’s shorter battery life—often around 4–5 hours of screen-on time—may finally see a full day of light to moderate use on a single charge. Early testers will want to monitor standby draw and how the external cover display affects overall battery drain during notifications and quick interactions.
Wireless and Fast Charging Capabilities
Beyond capacity, the new certification hints that both foldables will support 25 W wireless charging. This marks an upgrade for the Flip line, which peaked at 15 W wireless on the previous model. For US buyers, that means faster top-ups on Qi chargers and better compatibility with popular wireless charging pads from brands like Anker and Belkin.
On the wired front, Samsung is expected to maintain its 25 W USB Power Delivery standards over the US-friendly USB-C port. Combined with the dual-cell architecture, rapid charging should split intelligently across both modules to minimize thermal throttling. Still, third-party charger support and cable quality will play crucial roles in achieving the advertised speeds.
Release Timeline and US Pricing Estimates
Samsung has reportedly commenced mass production of both models, with a formal unveiling slated for mid-July. US preorders should open immediately afterward, accompanied by carrier deals from Verizon, AT&T, and T-Mobile. Trade-in promotions and Samsung’s own upgrade program will further sweeten the launch.
Based on prior releases, we anticipate US pricing to start around $1,899 for the base Galaxy Z Fold 7 model and approximately $1,099 for the Galaxy Z Flip 7. Higher-storage variants or premium color options may push prices closer to $1,999 and $1,199, respectively. Buyers should watch for bundle incentives, such as free Galaxy Buds or discounted Galaxy Watch offers.
What This Means for US Consumers
Overall, the Galaxy Z Fold 7’s battery consistency suggests Samsung prioritized design refinement over raw capacity gains. Fans of the Fold line who value slim profiles and flagship performance should see similar all-day endurance as before, with minor improvements in power management.
The Flip 7, however, stands to gain the most in battery terms. US users who were previously on the fence due to the Flip 6’s limited runtime may find this year’s model more viable as a daily driver. Combined with faster wireless charging and solid carrier support, the Flip 7 could cement Samsung’s dominance in the foldable market across the United States.
