iPhone Air vs Galaxy Z Flip8

battery, size and a missing water rating

Samsung prints 4,300 mAh for the Flip8. Notebookcheck reports 3,149 mAh for the Air. I'd buy the Flip8 unless you're staying on iPhone.

Amber marks my pick for that row.

Thin slab or a phone that folds in half? Pick one and you've mostly picked your battery too.

I haven't held either phone. What follows comes from Apple's and Samsung's own spec pages, read on November 7, 2026, plus battery figures reported by Notebookcheck and by iChip. The 7.4 and the picks are mine.

What they cost

The iPhone Air is $1,099Not verifiedNot verified (checked November 1, 2026). The Galaxy Z Flip8 is $1,199.99Not verifiedNot verified (checked November 1, 2026). Both start at 256GB.

The storage ceilings differ. Apple sells the Air with up to 1TB, and Samsung stops the Flip8 at 512 GB. If you shoot a lot of video and never delete anything, that matters more than any battery chart below.

Battery: the Air's dumb problem

Apple doesn't print a battery capacity for the Air. Notebookcheck reports 3,149 mAh, against 3,692 mAh for the base iPhone 17. Samsung prints 4,300 mAh for the Flip8. That's about 1,150 mAh more, in the phone that folds.

The tests back that up, with a caveat. Notebookcheck's article covers runs by YouTube reviewer Dave2D, not its own lab. In those, the Air lasted about 3 hours 11 minutes of Genshin Impact at 600 nits, where the iPhone 17 managed about 5 hours. In a Reddit and social-app run, the Air gave 9.5 hours of active use and the iPhone 17 just over 13. That's a big gap for a phone at this price.

For the Flip8, iChip reports GSMArena's average-load test at 14 hours 14 minutes, up from 11 hours 52 minutes on the Flip7. That's a secondhand report of GSMArena's figure.

Different tests, different people, so they don't sit on one scale. The maker claims can be compared, though. Apple says up to 27 hours of video. Samsung says up to 31.

Charging doesn't rescue the Air either. Apple says up to 50% in 30 minutes with a 20W or stronger adapter, sold separately. Samsung's product page gives no wired charging wattage for the Flip8.

Size, weight and the fold

The Air has a 6.5-inch OLED screen, weighs 165 g and is 5.64 mm thick. The Flip8 opens to a 6.9-inch screen and weighs 180 g. Unfolded, it's 6.1 mm thick. Samsung's page doesn't print the folded thickness or height.

So the Air is 15 g lighter, and about half a millimeter thinner than the Flip8 when it's open.

Water and dust

Apple rates the Air IP68, down to 6 meters for up to 30 minutes. Samsung's product page doesn't give the Flip8 an IP rating.

This annoys me. A phone with a hinge is exactly the one where I want to see the number before I take it to the beach.

Chips, cameras and updates

The Air runs Apple's A19 Pro. The Flip8 runs a Snapdragon 8 Elite Gen 5 for Galaxy. Neither spec page lists RAM.

On cameras, Apple lists a 48MP Fusion camera system. Samsung lists a 50 MP wide camera with what it calls "2x optical quality zoom." With no camera test to go on, I won't pick a winner here.

Samsung promises up to 7 OS upgrades and security updates. Apple's spec page doesn't state an update period.

Which I'd buy

If you're on Android, or willing to switch, I'd buy the Galaxy Z Flip8. It has the bigger battery, the longer video claim and a 14-hour GSMArena result. The missing IP rating is the one thing I'd check at the store before paying. It came out in July 2026, per Which?, so it's this year's model.

If you're staying on iPhone and want the thinnest one, the Air is the pick. Just plan your day around that 3,149 mAh cell. And budget for a power bank, because the box doesn't come with a charger either.

Every phone I cover is in phones.
