Make more of your iPhone: what duo-iphone.com is about

If you want to make more of your iPhone, you need dependable guidance rather than marketing promises. That is the aim of duo-iphone.com: we put news, models, accessories and iOS features into context and keep confirmed manufacturer information, our own assessment and rumours clearly apart. The site is written for readers who are about to buy a phone or who simply want to get more out of the one they already use.

The focus is on the iPhone Duo, which Apple presented on 9 September 2026 as its first foldable iPhone, according to the Apple Newsroom. For Germany, Apple names 16 October 2026 as the start of preorders and 23 October 2026 as the market launch. The inner display measures 7.6 inches and the outer display 5.4 inches; Apple lists the A20 Pro chip, and storage ranges from 256 GB to 2 TB. These are manufacturer specifications, not results of our own long-term testing, and we label them that way. We also cover the iPhone 18 Pro and the iPhone 18 Pro Max, because many readers weigh these models against each other.

We label key specifications as manufacturer specifications and name the source where known; concept images are clearly marked as editorial illustrations. We only mention our own measurements or hands-on impressions where they are documented in the article itself. How we work, how we handle corrections and how paid links are marked is explained on the page Editorial principles and transparency, which also states that paid links do not influence ratings or rankings.

Choosing the right iPhone: guides and comparisons

Choosing a model depends less on spec sheets than on how you use your phone. If you multitask, read documents or edit photos, the large inner display of the Duo offers more room. For quick messages and one-handed use, the compact outer display is the obvious choice. Whether switching between the two screens suits your routine is best tried out in person. The iPhone Duo model info page is a quick start with storage, eSIM, protection and charging.

Our iPhone comparisons place the Duo, the iPhone 18 Pro and the iPhone 18 Pro Max side by side by display, camera, battery, storage and use. We deliberately avoid artificial winners and explain instead who each model suits in everyday life. A good entry point is iPhone Duo vs iPhone 18 Pro; if you prefer to browse by topic, you will also find comparisons for travel, streaming and battery life.

If you have already decided, the guides hub helps with the switch: the preorder page with switching checklist, preparing your eSIM and transferring your data from your current phone. Practical iOS 27 guides, such as battery settings, and tips for the iPhone 18 Pro camera complete the picture.

Accessory tips: protection, charging and everyday use

With accessories, compatibility matters more than marketing. On a new foldable, parts that merely look similar can still fit badly. Check the exact model name and make sure the hinge and folding area can move freely. A generic label such as iPhone case is not proof of compatibility. For most people, a suitable case or folio, proper screen protection and a USB-C charger with a good cable are enough to start with. Stands, mounts or power banks should follow how you actually use the phone.

Our accessory checks collect articles on cases, chargers, power banks, mounts and audio. The iPhone Duo accessories page gives an overview by use case; we compare protection under cases and folios and in the Duo screen protection article. If you charge wirelessly, MagSafe and Qi2 explained covers the differences; according to the Duo overview, the Duo supports both and charges over USB-C when wired. Background is available in the article on USB-C charging.

Some model, accessory and guide pages contain product search links to Amazon.de that are marked as commission-based. A commission may be paid on purchases made through these links; they are not verified price or availability promises.
