Not a multi-day phone — yet. By Chase DiBenedetto on March 13, 2026.
Samsung’s upcoming Galaxy Z Flip 8 may not get as many upgrades as users are expecting, if a new leak turns out to be true. Alleged spec leaks suggest that the new entry into Samsung’s Razr-style flip phone line won’t be reinventing the battery, according to the blog GalaxyClub. The leak links two EB-BF776 and EB-BF777 batteries to the Z Flip 8 model, which Android Authority explains have a total rated capacity of 4,174mAh — the same capacity as the previous Galaxy Z Flip 7.
Other Android phones have upgraded their battery setups with silicon-carbon batteries, but the Z Flip has remained on a more standard 4,300mAh capacity battery, around 100mAh smaller than the Samsung Galaxy Z Fold 7.
Still, the Galaxy Z Flip 7 scored high marks in Mashable’s initial review, including the AI phone’s seamless cover screen, solid processing power, and all-day battery life. “I wouldn’t call this a multi-day phone, but it’s very not bad, and you’ll get a lot more mileage out of it if you use the cover screen as often as possible,” wrote our reviewer Adam Doud.
