3-Line TL;DR
- Apple's first foldable, the iPhone Duo, starts at $1,999 in the US, with preorders on October 16 and sales on October 23
- It is heavier and thicker than the Galaxy Z Fold8 and costs $100 more, but it runs the same A20 Pro as the iPhone 18 Pro
- I use a Galaxy Fold and will stay with Samsung, but if I did not live in Korea I would probably have bought the Duo
Only $100 more than the Fold8 in the US
Source: Apple US store, Samsung US, Apple Korea store, Fold8 Korean launch price report; checked October 15, 2026
- The Duo starts at $1,999 for 256GB and tops out at $3,199 for 2TB (Apple)
- That is $800 more than the iPhone 18 Pro, which starts at $1,199 (Apple)
- The Galaxy Z Fold8 starts at $1,899.99, so the gap with the Duo is just $99.01
- At that point the Duo stops looking like a luxury toy and starts looking like a normal foldable price
- Korea is a different story: Apple asks ₩3,290,000 for the 256GB Duo, while Samsung launched the Fold8 at ₩2,278,100
- So in Korea the Duo costs 1.44 times the Fold8, roughly a million won more
- Samsung's home market gets its phones at a friendlier price, which is the main reason I am staying with the Fold
Same chip as the iPhone 18 Pro, with a vapor chamber

- The Duo uses the A20 Pro, the same chip as the iPhone 18 Pro (Apple specs)
- The Fold8 runs the Snapdragon 8 Elite Gen 5 (Samsung)
- In Beebom's tests, the A20 Pro scored about 31% higher in Geekbench 6 single-core and about 23% higher in multi-core
- The bigger gap is in 3DMark stability, which compares the slowest of 20 GPU loops with the fastest
- The A20 Pro kept 80% of its speed, while the Snapdragon phone kept 25%
- Those scores came from other phones, so treat them as a chip comparison, not a Duo vs Fold8 test
- Apple says a vapor chamber cools the Duo's A20 Pro for demanding tasks and games (Apple)
- The chip, steady thermals and the feel of unfolding the screen are what make the Duo look worth it to me
- One caution: a pre-release unit reportedly got very hot during 4K recording and editing, with no measured temperatures (The Mac Observer)
- If your phone becomes your editing studio, wait for retail-unit heat tests
It still feels a little in-between
Source: Apple specs, Samsung US; each maker's own battery test
- At 254 g, the Duo is 53 g heavier than the 201 g Fold8
- Closed, it is 11.3 mm thick, 1.6 mm thicker than the Fold8
- There is no Face ID, so you unlock it with Touch ID in the side button
- Apple Pencil support is listed as coming later this year, so the note-taking pitch is not complete on day one
- In return you get up to 2TB of storage and Apple's rating of up to 31 hours of video on the inner screen
- That mix is why it feels in-between: too heavy to be an easy phone, too new to replace an iPad yet
| If you are... | My take |
|---|---|
| A US iPhone user curious about foldables | Worth buying; the $100 premium over the Fold8 is small |
| A Galaxy Fold user in Korea | Stay put; the Duo costs about 44% more there |
| Someone who edits 4K video on the phone | Wait for retail heat tests first |
| Waiting for the Fold9 | Watch whether Samsung answers on chip speed and sustained performance |
The Fold9 has homework now
- I will keep buying Folds, but the Duo came out more competitive than I expected
- Samsung still wins on weight and thickness, and the gap is not small
- What it should worry about is the A20 Pro's lead in sustained GPU speed
- If the Fold9 gets better cooling and keeps its home-market pricing, Fold users have little reason to switch
- If it does not, Apple's $100 premium looks easier to pay each year
Community Reactions
- One Hacker News commenter noted the Duo is priced close to the Samsung Fold8 with similar dimensions, but still preferred the Fold8's square edges (Hacker News)
- Another was surprised by $1,999 after reports of up to $2,500 and called it price competitive with other foldables (Hacker News)
- A long-time Galaxy Fold user simply called foldables the future (Hacker News)
- Others pushed back on paying $2,000 for a phone at all (Hacker News)
Q&A (Field Notes)
- Q. When can I buy it?
- Preorders open October 16 at 5 a.m. PT in the US and at 9 p.m. the same day in Korea, with sales starting October 23 in both
- Q. Is the A20 Pro in the Duo the same as in the iPhone 18 Pro?
- Apple lists the same chip, and my iPhone 18 Pro gaming post covers what it does in games, but the Duo's own sustained results still need testing
- Q. Is the crease gone?
- Apple says its display layers glide to minimize the crease, which is not the same as no crease, so check it in a store
- Q. Should a Fold8 owner switch?
- Only if you want iOS badly; the Duo is heavier and thicker, and in Korea it costs far more
