Dropping a foldable phone is the most common error users make, but the potential for damage often arises from the inner display. Items such as cards, coins, or keys can scratch or puncture the screen when the phone is closed. Samsung emphasizes the importance of ensuring that no foreign objects are atop the device before folding it shut.

Environmental factors can complicate care for foldable phones. For those working in dusty conditions or living near the beach, it can be difficult to keep sand or dirt from entering the device, which can lead to damage.
Different models of foldable phones offer varying levels of durability. For instance, the Galaxy Z Fold8 and Fold8 Ultra have an IP48 rating, while the iPhone Duo has a higher IP68 rating. The first digit in these ratings indicates protection against solid particles, with a rating of 4 meaning that particles 1mm and larger cannot enter, and a 6 indicating a device that is completely dust-tight.
Users should handle the inner display of a foldable phone with special care, as it does not have the same robustness as traditional screens. Actions like scratching at minor smudges with a nail can damage the display. Additionally, users should resist the urge to remove factory-applied protective films, as Samsung recommends keeping these in place. Likewise, applying an unapproved screen protector could adversely affect the foldable display; only those specifically designed for a model should be used.
As for lifespan, foldable phones do not have a set longevity, but manufacturers conduct tests by folding devices between 200,000 and 500,000 times. If a user opens and closes their device 100 times daily, it may last between 5 to 10 years under those conditions. However, this is not guaranteed, as real-world usage can differ from lab testing. For example, while Samsung claimed the Galaxy Z Fold7 could function after 500,000 folds during testing, historical data suggests that earlier models fell short of similar endurance in actual use.
Ultimately, users should prioritize checking for dirt or foreign objects before closing their foldable phones and be cautious about the level of pressure applied to the display. Regular maintenance, such as using a soft cloth to wipe the screen, is crucial to prolonging the device's lifespan. Users should be aware that while features like the IP68 rating imply strong resistance to water and dust, these protections can diminish with normal use.
