The Samsung Galaxy Z Fold 8 is rumored to bring a noticeable battery upgrade, with a total capacity of about 4,854 mAh – around 13% more than the Samsung Galaxy Z Fold 7.
This would mark the first significant increase in years for Samsung foldables, potentially boosting real-world battery life. The phone is expected to be marketed with a typical 5,000 mAh capacity.
Despite the improvement, it may still fall short of the upcoming Apple iPhone Fold, which is rumored to feature a larger 5,500 mAh battery.
