TL; DR
  • The Samsung Galaxy Z Fold7 will feature a 4,400 mAh battery, just like the Z Fold6.
  • The Z Flip7, on the other hand, will get a 300 mAh boost, making the battery 4,300 mAh.
  • Samsung is also expected to launch an FE version of the Z Flip7, called the Z Flip7 FE. 
  • All the foldables and the Watch8 series will be unveiled at the Samsung Unpacked scheduled for July 9, at 7:30 PM.

Samsung’s foldables are getting thinner and lighter, but one thing that hasn’t changed is the battery on the Galaxy Z Fold7. Just like last year, the new Fold will pack a 4,400 mAh battery, as confirmed through its EPREL certification. And while this is the case with the Fold7; the Z Flip7, on the other hand, gets a boost to 4,300 mAh, up from 4,000 mAh on the Flip6. 

Samsung Galaxy Z Fold7: What to Expect 

Z Fold7

Despite the unchanged battery size, Samsung is clearly pushing forward in other areas. The Fold7 is expected to be Samsung’s slimmest book-style foldable yet, measuring just 4.5mm when open and about 9mm when folded. 

It’s also reportedly 11mm wider than the Z Fold6, giving the outer display more real estate—up to 6.5 inches, while the inner display stretches to 8.2 inches. That solves one of the biggest complaints about earlier Z Folds: a narrow, cramped cover screen.

The design refinements go further with slimmer bezels, a sleeker hinge, and possibly less crease on the inner screen. The device is also lighter, dropping down to 215g from the 239g Z Fold6. This will crown it the lightest book-style foldable ever.

Inside, you’ll find the Snapdragon 8 Elite for Galaxy, likely paired with faster storage and improved thermals. The camera setup is rumored to finally get serious, with a 200 MP main sensor, plus a 12 MP ultra-wide and a 10 MP 3X telephoto lens. The under-display selfie camera is being replaced with a 10 MP punch hole camera.

While the Fold7 remains stuck with 4,400 mAh, the clamshell-style Galaxy Z Flip7 gets a small but notable bump. The Flip7 will come with a 4,300 mAh battery—up from 4,000 mAh on the Flip6. That’s confirmed by EPREL listings, which also mention up to 42 hours of single-charge usage. 

The Flip7 retains a compact footprint (13.7mm folded, 6.5mm open) but now features a 6.9-inch inner screen and a larger 4.1-inch outer display.

Also new this year is the Galaxy Z Flip7 FE—Samsung’s first Fan Edition foldable. It is said to feature a 4,000 mAh battery (3,887 mAh rated), and bring the Flip experience to a lower price bracket. Both Flip models this year will feature an Exynos chipset.
