Galaxy Z Flip7 & Z Fold7 

In 2025, the foldable smartphone market has matured significantly, with competitors pushing the envelope in terms of design, performance, and especially battery life.  

For many fans and tech enthusiasts, this came as a disappointment, especially when battery longevity has long been the Achilles heel of the Galaxy Z series. 

The launch of the Galaxy Z Flip7 and Z Fold7 was the perfect moment for Samsung to debut its rumored new battery technology—possibly using stacked battery design or advanced silicon-anode cells. 

This is a missed strategic opportunity at a time when consumers expect flagship devices—especially premium foldables—to be uncompromising in every aspect.  

With battery life being a make-or-break factor for many users, Samsung risks losing its dominance in the foldable segment if it continues to underdeliver in this area. 

User feedback so far reflects mixed sentiments. While some appreciate the improved cameras and software upgrades, others feel let down by the battery capacities.  

Samsung had the perfect chance to leap ahead of its competition in 2025 by introducing new battery technologies in the Galaxy Z Flip7 and Z Fold7.
