Durability: Are Foldable Phones Suitable for Everyday Use?
Many consumers have a common concern when first encountering foldable phones: are foldable screens durable enough? Compared to traditional candybar phones, foldable screens have a more complex structure, especially the hinge and flexible screen itself. Therefore, they require more care to protect during daily use.
The iPhone Duo features a Grade 5 titanium construction, Ceramic Shield 2 outer screen protection, and a Ceramic Shield back panel, offering an IP68 protection rating. Apple further enhances the device's overall strength through multi-layered materials, internal support structures, and a precision hinge design. The Galaxy Z Fold8 uses an Armor Aluminum frame, Gorilla Glass Ceramic 3 outer screen, and Gorilla Glass Victus 2 back panel, along with a reinforced folding hinge structure. Its protection rating is IP48.
It's important to note that IP68 and IP48 do not mean that foldable screens are completely immune to damage. The testing standards for these two standards differ, especially regarding protection against dust and particulate matter. Therefore, it cannot be simply assumed that foldable phones can be used as casually as regular candybar phones.
Why Do Foldable Phones Need Better Protection?
Foldable phones are typically expensive, and screen repairs can be costly. Therefore, choosing suitable protective accessories after purchasing the phone is crucial. For foldable phones, the case not only needs to protect the exterior but also needs to be slim to avoid adding weight or bulk, offer a comfortable grip, be compatible with magnetic accessories, and protect the hinge area.
aulumu has also released corresponding phone cases for these two foldable phones. The two iPhone Duo cases are made of aramid fiber, designed for users who prefer unique aramid fiber protective cases and a refined, ultra-thin feel. The case body uses 1500D imported aramid fiber with a dual-screen full-coverage bezel design, combined with an aluminum alloy lens protector for a reinforced structure, offering both high-level protection and strong magnetic fit. The case is only 1.4 mm thick and weighs approximately 30 grams, achieving a balance between lightweight protection and a unique particle array aesthetic for the iPhone Duo. There's no need to worry about adding extra weight to the phone.

Both the main display and the cover display have protective bezels around their edges. Reinforced corners and a raised TPU camera protector reduce everyday scratches and prevent the camera from directly contacting flat surfaces. The magnetic hinge cover moves synchronously with the device's folding and unfolding, always covering and protecting the hinge area. Built-in magnets ensure compatibility with MagSafe accessories, including the aulumu G09 magnetic stand.
Price and Value: Which Foldable Is Worth the Investment?
For first-time foldable phone buyers, price is also a significant factor. Both products belong to the high-end foldable phone market, but their starting prices differ by approximately $100. While the price difference isn't particularly large, consumers also need to consider the cost of storage capacity, protective cases, charging devices, and other accessories.
The iPhone Duo's advantages lie in the Apple ecosystem, its long-standing software experience, and its ability to collaborate with other Apple devices. The Galaxy Z Fold8, on the other hand, offers a lighter body, a more flexible Android operating experience, and Samsung's mature foldable screen product portfolio. If you already own a large number of Apple devices, the iPhone Duo, even with its slightly higher price, may better suit your long-term needs. Conversely, if you want to experience the large-screen multitasking capabilities of a foldable screen and value portability, the Galaxy Z Fold8 is highly competitive.
Which Foldable Should First-Time Buyers Choose?
Based on the above comparisons, we can provide more specific purchase recommendations according to different user needs.
