6 things to know before you buy the iPhone Duo

Before purchasing the iPhone Duo, there are six key factors to consider. Firstly, the front screen of the device includes a persistent sidebar for frequently used apps, which replaces the traditional iPhone dock at the bottom. While this is a clever design choice, it does take up space and may make the front screen feel cramped, especially when opening websites.

Secondly, you should anticipate unfolding the device more frequently than you might expect. The inner display of the Duo offers a larger canvas for everyday tasks, leading users to reach for the larger screen more often. Thirdly, the larger inner screen excels at reading, watching videos, and typing, offering a natural feel for everyday work.

Many users may even choose to use it as their primary screen most of the time. Fourthly, not every app is optimized for the Duo yet. While many apps have been optimized for the outer display, developers still need to work on fully utilizing both screens. LinkedIn, for example, appears as a regular iPhone app on the larger screen, which can be awkward.

Fifthly, the Duo replaces Face ID with a side-mounted Touch ID button, requiring users to register a finger from each hand. This change may lead to awkward moments if you aren't prepared for it. Lastly, the Duo's battery is a strong point, with a dual-battery design that provides battery life close to that of the iPhone 18 Pro Max, lasting well over a day with regular use.

In conclusion, the iPhone Duo offers a unique iPhone experience, and whether it suits you depends on your priorities. If a larger screen is what you're seeking, the compromises on the front screen and some apps should be more easily manageable.
