Samsung Galaxy Z Flip8 review: the battery test and the specs

Samsung Galaxy Z Flip8 review

more battery, and one test to prove it

The Galaxy Z Flip8 ran 14 hours 14 minutes in GSMArena's battery test, as reported by iChip, against 11 hours 52 minutes for the Flip7. That's the only published test I could read, so there's no score yet.

My verdict

No score yet. The one test I could read is a secondhand battery result, and it's a good one: 2 hours 22 minutes more than the Flip7. I'd look at the Flip8 if battery life kept you away from flip phones, and I'd keep a Flip7 if you already own one.

What I like

14 h 14 min in GSMArena's average-load battery test, per iChip (Flip7: 11 h 52 min)

Up to 7 OS upgrades and security updates, per Samsung

180 g and 6.1 mm unfolded, per Samsung

Snapdragon 8 Elite Gen 5 for Galaxy chip

What annoys me

Only one published test I could read, and it covers battery only

Samsung's US specs page didn't load, so RAM, IP rating and charging speed are unconfirmed

No camera or screen test I could read

Which?'s review is paywalled, so its verdict is unknown to me

I haven't used the Galaxy Z Flip8. I'm working from Samsung's US product page, read on November 7, 2026, and from one battery result: GSMArena's, as reported by iChip on August 24, 2026. That's the only published test I could read.

Which? has reviewed it too. The page is paywalled, so I can't tell you what it found. Which? does say the phone came out in July 2026.

One secondhand number isn't enough for a score. So there isn't one.

The price

The Flip8 is $1,199.99Not verifiedNot verified as of November 1, 2026, for the base 256 GB model, unlocked. Samsung also sells a 512 GB version. I haven't priced that one.

Battery, the one thing someone measured

GSMArena's average-load test ran the Flip8 for 14 hours 14 minutes. The Flip7 managed 11 hours 52 minutes in the same test, per iChip. That's 2 hours 22 minutes more, or about 20%, by my arithmetic.

A caveat. I didn't read GSMArena's own page; the figure reaches me through iChip, which credits GSMArena. I'd trust it more with a second outlet behind it, and none I could read has published one.

Samsung's own claim is up to 31 hours of video playback from a 4300 mAh battery. Nobody I could read has tested that.

What Samsung lists

Open, the screen is 6.9 inches. Closed, the cover screen is 4.1 inches. The phone weighs 180 g and is 6.1 mm thick unfolded. It runs a Snapdragon 8 Elite Gen 5 for Galaxy, and the main camera is a 50 MP wide with what Samsung calls 2x optical-quality zoom.

The line I'd weigh hardest is the update promise: up to 7 OS upgrades plus security updates. On a phone at this price ($1,199.99Not verifiedNot verified), that's what spreads the cost over years. I'd hold Samsung to it.

What I couldn't confirm

Samsung's US specs page didn't load for me on November 7, 2026. The product page I read doesn't list RAM, the IP rating, wired charging speed or folded height. You'll see figures for all four elsewhere, and I can't stand behind any of them yet. If dust or water resistance matters to you, check the rating on Samsung's page before you pay.

The camera and screen haven't been tested anywhere I could read. That bothers me more than the missing RAM figure.

If you own a Flip7

Keep it. Two hours and 22 minutes in one test is a real gain, but it doesn't justify spending $1,199.99Not verifiedNot verified on a phone that replaces one from the previous year.

If battery kept you away from flip phones

This is the case for the Flip8. The GSMArena figure is the reason I'd look at it at all, and the update promise is the reason I'd keep it a long time. I'd still wait for a second test before buying.
