Samsung Galaxy Z Flip 7 could fix its predecessor's biggest weakness

Samsung's flagship phones, like the Galaxy S25 Ultra, deliver excellent battery life, easily lasting over a day of heavy use. The same is not true for its foldable phones, though, which struggle to last a full workday under heavy load — mainly due to their relatively tiny batteries. Last year, Samsung increased the Galaxy Z Flip 6’s battery from 3,700 mAh to 4,000 mAh for better longevity. Given the modest yearly changes that Samsung phones typically pack, the company will surprisingly give another battery boost to its flip foldable this year.
