Samsung unveiled the Galaxy Z Fold7 with a 4,400 mAh battery, the same as its predecessor, despite the device's dual screens consuming more power.
The decision not to increase the battery size was driven by user preferences, with Fold7 users prioritizing improvements in other areas such as cameras, weight, and screen size.
The trade-off for a slimmer design limited the space available for a larger battery, indicating a challenge in accommodating a bigger power source.
Rivals using advanced battery technologies like silicon-carbon (Si/C) batteries may prompt Samsung to upgrade battery options in future Fold models for enhanced performance.
