iPhone 18 Foldable Ultra Launch: Apple's First Folding iPhone Explained
If you are tracking the 2026 smartphone market, Apple's September 9 "Surprise and Shine" event is impossible to ignore: the first foldable iPhone is finally here, the A20 Pro 2nm chip debuts, and iOS 27 brings a full overhaul. This post is both a quick spec sheet for the iPhone 18 lineup and a buying guide—use the table and key points below to decide whether this foldable is worth your money.
Launch Context
- Historic milestone: Apple finally enters the foldable arena with a book-style inward fold, offering a ~7.8-inch display that rivals the iPad mini when opened.
- Performance leap: The A20 Pro uses TSMC's 2nm process, delivering roughly 18% more performance and 30% better efficiency, paired with 12GB of RAM for Apple Intelligence.
- Premium pricing: Starting at approximately $2,099 (around 14,085 RMB), it becomes the most expensive iPhone ever, targeting the ultra-premium segment.

Key Facts
Here is a side-by-side comparison of the three models:
| Spec | iPhone Ultra | iPhone 18 Pro | iPhone 18 Pro Max |
|---|---|---|---|
| Chip | A20 Pro (2nm, WMCM, 12GB LPDDR5) | same | same |
| Cover display | 5.5" OLED (folded) | 6.3" OLED | 6.9" OLED |
| Inner display | 7.8" OLED (unfolded) | — | — |
| Camera | Dual (main + ultrawide) | Triple (variable aperture) | Triple (variable aperture) |
| Battery | ~3500mAh | ~4400mAh | ~4700mAh |
| Starting price | ~$2,099 | ~$1,099 | ~$1,199 |
| OS | iOS 27 | iOS 27 | iOS 27 |
Every model gets the A20 Pro, using a 2nm process and WMCM packaging that integrates RAM onto the same wafer as the CPU and GPU. The Ultra unfolds to a ~7.8-inch inner OLED with an iPad mini-style landscape layout and dual-app split-screen support. The Ultra starts around $2,099 with constrained launch supply, while the Pro series pricing stays flat year-over-year.
Key Highlights
Apple invested heavily in foldable engineering, with three areas standing out:
- Liquid metal hinge: A liquid metal alloy hinge balances durability and crease management, with Apple claiming 200,000 fold-cycle testing.
- Optically clear adhesive: A special optically clear adhesive layer between panels keeps the crease less visible over long-term use.
- Side Touch ID: Because the folded body is extremely thin (roughly 4.5mm per side), Face ID is replaced by side-mounted Touch ID.
These details show Apple did not simply copy Android foldables—it redefined the folding experience from materials, interaction, and system levels.
Buying Advice
- [ ] Confirm budget: iPhone Ultra starts around $2,099; evaluate whether you need max storage
- [ ] Check supply: Foldable production is limited at launch; expect longer shipping times
- [ ] Verify carrier bands: Regional variants support different 5G frequency bands
- [ ] Assess use case: A 7.8-inch inner screen is great for multitasking but less convenient one-handed
- [ ] Review warranty: Foldable repairs are expensive; AppleCare+ is strongly recommended
- [ ] Compare alternatives: Samsung's Galaxy Z Fold 8 is already available, cheaper, and has a mature ecosystem
Industry Positioning and Impact
The iPhone Ultra launch marks Apple's official entry into the foldable era, with the A20 Pro chip and iOS 27 delivering a unique hardware-software combination. The $2,099 starting price is steep, but for users who want cutting-edge technology, the appeal remains strong. Given constrained supply, a rational assessment of your needs is advisable before committing. For the foldable segment, Apple's entry should accelerate supply-chain maturity and price erosion while applying direct competitive pressure on incumbents like Samsung and Xiaomi.
