iPhone 18 Pro vs iPhone Duo: Prices and Who Should Upgrade

Which new iPhones did Apple actually launch in 2026?

Apple's September 2026 launch did not include a standard iPhone 18. On 9 September Apple announced three new models: the iPhone 18 Pro, the iPhone 18 Pro Max and its first foldable, the iPhone Duo ^[3][4]. As of 13 November 2026 Apple's US store lists six iPhone lines: iPhone Duo, iPhone 18 Pro and Pro Max, iPhone Air, iPhone 17, iPhone 17e and iPhone 16 ^[1]. The UK store lists the same six ^[2].

The foldable is not called iPhone Fold or iPhone 18 Fold; Apple's name is iPhone Duo ^[3]. A cheaper iPhone 18, an iPhone 18e and a second iPhone Air are expected in spring 2027 according to reports compiled by MacRumors, but Apple has not announced them, so treat them as rumour ^[9].

When could you buy them?

The 18 Pro and Pro Max went on pre-order on 12 September and on sale on 18 September in more than 65 countries and regions, with about 20 more from 25 September ^[4]. iPhone Duo followed later: pre-orders on 16 October and availability from 23 October in more than 70 countries and regions, including the US, the UK and Türkiye, and 28 more from 30 October ^[3].

How much do the iPhone 18 Pro and iPhone Duo cost?

In the US, the iPhone 18 Pro starts at $1,199, the Pro Max at $1,299 and the iPhone Duo at $1,999 ^[1][4][3]. In the UK, Apple's store lists the iPhone 18 Pro from £1,199 and the iPhone Duo from £1,999 ^[2]. Each country has its own pricing and tax treatment, so the pound and dollar figures are not directly comparable.

Storage drives the price up quickly. On the US store, the iPhone 18 Pro runs from $1,199 for 256GB to $2,399 for 2TB, and iPhone Duo from $1,999 for 256GB to $3,199 for 2TB ^[10][11]. Apple also offers iPhone Duo from $83.29 a month over 24 months in the US ^[3].

Did older iPhones get more expensive?

Yes. MacRumors reported that on launch day Apple raised the US starting prices of the iPhone 16, iPhone 17, iPhone Air and iPhone 17e by $100 each ^[8]. On 13 November Apple's US store showed the iPhone Air from $1,099 and the iPhone 17e from $699, matching those figures. It showed the iPhone 17 from $899 with carrier activation (a footnote ties this price to a $30 connectivity discount) and $929 unlocked, and $829 for an unlocked 128GB iPhone 16 ^[1][12]; the $799 starting price MacRumors reported for the iPhone 16 was not visible on the store page. MacRumors linked this to memory costs, citing earlier comments by Tim Cook to The Wall Street Journal; that explanation is reported, not stated in Apple's press releases ^[8]. The guide RAM Shortage covers why memory got pricier.

Apple's September press release listed Apple Trade In credit of $175 to $885 in the US for an iPhone 13 or later ^[4]. Apple says trade-in values vary with the condition, year and configuration of the device ^[10], so check the figure on the day you buy.

What is different about the iPhone Duo?

iPhone Duo is a book-style foldable. Closed, it has a 5.4-inch outer display that Apple says gives 90% of the screen area of the iPhone 18 Pro; opened, a 7.6-inch inner display that Apple says is 50% larger than the iPhone 18 Pro Max ^[3]. Both screens share the same aspect ratio, and the inner screen has a nano-texture finish that Apple says reduces glare and minimises crease visibility ^[3].

Other differences from the Pro models, from Apple's specifications ^[3][7]:

• Unlocking: Touch ID in the side button rather than Face ID ^[3].
• Size: 5.2 mm thick open and 11.3 mm closed, at 254 g, heavier than the 18 Pro's 211 g and close to the Pro Max's 249 g ^[5][7].
• Cameras: a 48MP Fusion main camera that also gives a 12MP 2x optical-quality crop, plus a 48MP ultra wide, but no dedicated telephoto lens; the Pro models add a 4x telephoto ^[5][7].
• Battery: Apple lists up to 44 hours of video playback on the outer display and 31 hours on the inner display ^[7].
• SIM: eSIM only, on both the US and UK specifications ^[7][13]. The guide What Is an eSIM? explains what that means if you travel or switch carriers often.

Apple said iPhone Duo would support Apple Pencil with USB-C later in 2026 ^[3]; check that this has arrived before you buy for note-taking.

iPhone 18 Pro or Pro Max: what changed?

The iPhone 18 Pro has a 6.3-inch display and the Pro Max 6.9-inch ^[5]. Both use the A20 Pro chip, which Apple says is built on a 2-nanometre process, and Apple's N1 wireless networking chip; Apple says the iPhone 18 Pro introduces its C2 cellular modem system, and mmWave is now supported in the US ^[4]. The main camera is a 48MP Fusion sensor with a variable aperture, a first for iPhone according to Apple ^[4]. Storage goes up to 2TB ^[1][5]. Colours are burgundy, glacier, silver and black ^[4].

The changes Apple highlights are the A20 Pro chip, the variable-aperture main camera and, on the 18 Pro, the C2 modem ^[4]. Whether that justifies an upgrade depends on the phone you have now.

Are US and UK iPhones the same?

Not quite, and the difference matters for battery claims. Apple sells eSIM-only iPhone 18 Pro and Pro Max models in the US and several other countries, including Canada, Japan, Mexico, Saudi Arabia and the UAE ^[4]. In the UK, Apple's specifications list the 18 Pro with both a nano-SIM slot and eSIM ^[6].

The eSIM-only version lists more battery life. Apple's US specifications list up to 36 hours of video playback for the 18 Pro and 45 hours for the Pro Max ^[5], while the UK specifications list 34 and 43 hours ^[6]. If you read a battery figure in a review, check which version was tested. iPhone Duo is eSIM only in both countries, with the same 44 and 31 hours listed ^[7][13].

If you buy an iPhone abroad, check that it supports your home carriers' bands and eSIM, and remember that warranty and returns are handled by the country of purchase.

Should you upgrade now or wait?

A simple way to decide:

• You want the newest Pro camera and chip: the iPhone 18 Pro or Pro Max is the current top of the range ^[4].
• You want a phone that becomes a small tablet: iPhone Duo is Apple's only foldable, but at $1,999 or £1,999 to start it costs $800 more than the 18 Pro in the US, has no dedicated telephoto lens and is first-generation hardware ^[1][3].
• You normally buy the standard iPhone: there is no iPhone 18 yet. Reports point to spring 2027, but that is not confirmed by Apple ^[9]. Meanwhile, Apple's US store showed the iPhone 17 from $899 with carrier activation ($929 unlocked) on 13 November, after the price rise ^[8][12].
• Your phone works fine and gets updates: waiting costs nothing; prices for older models went up, not down, this year ^[8].

What is still only rumour?

Anything not on Apple's site is unconfirmed. That includes the timing, name and price of a standard iPhone 18, an iPhone 18e and an iPhone Air 2, all reported for spring 2027 ^[9]. MacRumors' roundup collects reports and analyst claims rather than Apple announcements, so plans can change ^[9].

Apple did confirm some software items as coming later, such as Apple Pencil support on iPhone Duo and support for the SynthID standard, which Apple says can help identify AI-generated or AI-edited images on the 18 Pro models ^[3][4]. Confirmed-but-not-shipped is different from shipped: check Apple's release notes before relying on it.
